Bump version to v3.8.5

This PR implements a new lua function and packet used for sends dialogs
to the client.

## Example:


https://github.com/user-attachments/assets/97bb5813-ea12-4b1d-a049-2f7ebf6b6da3

Example serverside code:
```lua
--MP.ConfirmationDialog(player_id: number, title: string, body: string, buttons: object, interaction_id: string, warning: boolean = false, reportToServer: boolean = true, reportToExtensions: boolean = true)

function onChatMessage(player_id, player_name, message)
    MP.ConfirmationDialog(player_id, "Warning", "Watch your tone buddy!!", 
        {
            {
                label = "OK",
                key = "dialogOK",
                isCancel = true
            }
        }, "interactionID", true)
end

MP.RegisterEvent("onChatMessage", "onChatMessage")


function dialogOK(player_id, interaction_id)
    MP.SendChatMessage(-1, MP.GetPlayerName(player_id) .. " clicked OK")
end

MP.RegisterEvent("dialogOK", "dialogOK")
```

### Details:
Each dialog can have multiple buttons, each button having it's own
callback event (`key`).
Each dialog can also have one button with `isCancel` being true,
settings this property to true causes the button's event to be called
when the users pressed `esc` to exit out of the dialog. If a dialog is
created without any button being the cancel button then the user will
only be able to exit the dialog by restarting the session or pressing
one of the buttons.

`interaction_id` will be sent as the event data with a button press
event, to track from which dialog the button press came. As when
multiple dialogs are opened they will stack and it will become difficult
to track what button on which dialog was pressed without having multiple
event handlers.

+# Contributing to BeamMP-Server
+
+Unlike other parts of BeamMP, the BeamMP-Server does not have any dependency to the BeamNG.drive game. 
+
+To contribute *C++ code*, you'll need a MacOS, Linux or Windows PC, and intermediate to advanced knowledge of C++.
+For reference, you should know be reasonably comfortable with the STL, the concept of RAII, templates, and generally know how to read & write post-C++17 code. To contribute anything else, you won't need most of this (though it'd be helpful to have some vocabulary about computers).
+
+# Ways to Contribute
+
+## Bug Reports
+
+If you work with BeamMP-Server, either by simply using it, or even writing plugins for it, and you run into any issues, we definitely want to know about it. Please use [GitHub issues](https://github.com/BeamMP/BeamMP-Server/issues) and select the "Bug" template, read it, and fill it out accordingly.
+
+## Bug Fixes
+
+If you are interested in fixing bugs, check out the [GitHub issues](https://github.com/BeamMP/BeamMP-Server/issues). There, you can pick any issue that has nobody assigned to it. For example, some bugs which we definitely need some help with are marked with the "help wanted" tag.
+
+Once you picked a bug, you need to reproduce it. Start by following the instructions in the bug report, and don't be afraid to ask for more information or clarification on the issue itself.
+
+Refer to [getting started with the codebase](#getting-started-with-the-codebase) for more information on how to build the server. You can also ask on our [Discord server](https://discord.gg/beammp), or on IRC ([irc.libera.chat](https://web.libera.chat/), join `#beammp`).
+
+## Features
+
+If you want to add new features, please make an issue for it first or ask on our [Discord server](https://discord.gg/beammp), or on IRC ([irc.libera.chat](https://web.libera.chat/), join `#beammp`).
+
+You need to make sure the feature isn't being worked on by someone else, and aligns with the vision we have for the server.
+
+# Git Guidelines
+
+**Read this carefully. Failing to follow these rules results in your changes not being accepted**. This applies for outside contributors, members of the BeamMP development team ("BeamMP Developers"), project owners, maintainers, frequent contributors, and literally everyone else. **It applies to everyone**.
+
+## How to Commit
+
+Commit messages **MUST** (mandatory):
+
+- start with a **lower case action verb in present tense**, for example `add`, `fix`, `implement`, `refactor`, `remove`, `rename`. *Counter examples (these are bad): ~~`Fixed`, `fixing`, `added`, `removing`~~*.
+- not have a first line much longer than 70 characters.
+- explain briefly the changes made.
+- reference the issue by number, if there is an issue the commit addresses, like so: `#<number>`. Example: `#123`.
+
+If any of these are not followed, **your changes will not be accepted.**
+
+Commit messages **SHOULD** (optional, "nice to have"):
+
+- only address one "atomic" change.
+- have an empty second line, and the subsequent lines explaining the changes in more detail (if more detail is available).
+
+Commits may be squashed (via a Git "interactive rebase") in order to satisfy these rules, but history that is >1h old should not be rewritten if possible. Force pushes are ugly ;)
+
+## Pulling, Merging
+
+Do **NOT** pull with merge. This is the default git behavior for `git pull`, but creates ugly and unnecessary commit messages like `"merge origin/master into master"`. Instead, pull with rebase, for example via `git pull -r`. If you get conflicts, resolve them properly.
+
+The only acceptable merge commits are those which actually merge functionally different branches into each other, for example for merging one feature branch into another.
+
+## Workflow
+
+### Making an issue and fixing it
+
+1. Create an issue detailing the feature or bug.
+2. Assign a milestone to the issue, or wait for a maintainer to add a milestone to your issue.
+3. Fork the repository and base your work on the branch mentioned in the milestone attached to your issue (e.g. `v3.0.0 (develop)` -> `develop`).
+4. Program your feature or bug fix.
+5. Open a PR that references the issue by number in the format: `#12345`.
+6. Someone will review your PR and merge it, or ask for changes.
+
+### Fixing an existing issue
+
+1. Fork the repository and base your work on the branch mentioned in the milestone attached to your issue (e.g. `v3.0.0 (develop)` -> `develop`).
+2. Program your feature or bug fix.
+3. Open a PR that references the issue by number in the format: `#12345`.
+4. Someone will review your PR and merge it, or ask for changes.
+
+## Branches
+
+- `minor`: Minor releases, like `v1.2.3` -> `v1.3.0` or `v1.2.3` -> `v1.2.4`.
+- `develop`: Major releases, like `v1.2.3` -> `v2.0.0`, and larger feature/minor releases.
+
+## Unit tests & CI/CD
+
+We use GitHub Actions, which runs our unit-tests. PR's which fail these tests, or even fail any of our actions (which run automatically), will not be merged and require further changes until they compile, link, and all tests pass properly. If you have issues with this, feel free to ask in our [Discord server](https://discord.gg/beammp), or on IRC ([irc.libera.chat](https://web.libera.chat/), join `#beammp`)
+
+### What should I call by branch?
+
+Keep branch names **unique**, **descriptive**, and **shorter than 30 characters**. Names must be in present-tense, such as `fix-xyz`, **not** ~~`fixing-xyz`~~.
+
+We generally use *feature branches*, so we keep one branch per feature or fix.
+
+For example:
+- You want to fix issue number #123? You could call the branch `fix-123`.
+- You want to add a feature described in issue #456? You could call the branch `implement-456`.
+- You want to add a feature or fix a bug that has no issue? You should probably make an issue for it first! Or, if you're not ready for that yet, you could call it by the feature name or bug description, for example for a bug that makes cars disappear: `fix-disappearing-cars`.
+
+## Pull Requests, Code Review
+
+Once you are ready to show what you did, and get feedback on it, you open a Pull-Request on GitHub. Please make sure to pick the right branches, and a descriptive title. Mention any related issues with `#<issue number>`, for example `#123`.
+
+Make sure to explain what the PR does, what it fixes, and what needs to still be done (if anything).
+
+A BeamMP-Developer must review your code in detail, and leave a review. If this takes too long, feel free to @ a maintainer/developer, or leave another comment on the PR. It helps to say something like "Ready for review", for example.
+
+# Getting Started with the Codebase
+
+1. Look at current Pull-Requests, look at the git branches, or ask in our [Discord server](https://discord.gg/beammp), or on IRC ([irc.libera.chat](https://web.libera.chat/), join `#beammp`), in order to find out which branch you should work on to minimize conflict. See [this section on branches](#branches) for more info.
+2. Fork the repository (with that branch) on GitHub. GitHub, by default, gives you only the `master` branch when forking, so make sure you fork with other branches enabled when you want to work on a branch that isn't master (it's a checkbox when you fork).
+3. Clone the fork to your local machine.
+4. Check out the branch you want to work on (see 1.).
+5. Run `git submodule update --init --recursive`.
+6. Make a new branch for your feature or fix from the branch you are on. You can do this via `git checkout -b <branch name>`. See [this section on branches](#branches) for more info on branch naming.
+7. Install all dependencies. Those are usually listed in the `README.md` in the branch you're in, or, more reliably, in one of the files in `.github/workflows` (if you can read `yaml`).
+8. Run CMake to configure the project. You can find tutorials on this online. You will want to tell CMake to build with `CMAKE_BUILD_TYPE=Debug`, for example by passing it to CMake via the commandline switch `-DCMAKE_BUILD_TYPE=Debug`. An example invocation on Linux with GNU make would be 
+`cmake . -DCMAKE_BUILD_TYPE=Debug` . 
+9. Build the `BeamMP-Server` target to build the BeamMP-Server, or the `BeamMP-Server-tests` target to build the unit-tests (does not include a working server). In the example from 8. (on Linux), you could build with  `make BeamMP-Server`, `make -j BeamMP-Server` or `cmake --build . --parallel --target BeamMP-Server` . Or, on Windows, (in Visual Studio), you would just press some big green "run" or "debug" button.
+10. When making changes, refer to [this section on how to commit properly](#how-to-commit). Not following those guidelines will result in your changes being rejected, so please take a look.
+11. Make sure to add Unit-tests with `doctest` if you build new stuff. You can find examples all over the latest version of the codebase (search for `TEST_CASE`).
+
+# Code Guidelines
+
+## Formatting
+
+1. Use `clang-format` to format your code before committig. A `.clang-format` file is provided in the root of the repository.
+2. All identifiers, type names, function names, etc. should be `PascalCase`. Type names may also have the `T` prefix, although this is not enforced (for example `TNetwork`).
+
+## Modular code
+
+Write code that is modular and testable. Generally, if you can write a good unit-test for it, it's modular. If you can't, it's not.
+
+Don't overdo it though - sometimes its okay to just write code, do the job, be done with it. You'll get feedback on this in the code review for your PR.

+                       Version 3, 19 November 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU Affero General Public License is a free, copyleft license for
+software and other kinds of works, specifically designed to ensure
+cooperation with the community in the case of network server software.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+our General Public Licenses are intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  Developers that use our General Public Licenses protect your rights
+with two steps: (1) assert copyright on the software, and (2) offer
+you this License which gives you legal permission to copy, distribute
+and/or modify the software.
+
+  A secondary benefit of defending all users' freedom is that
+improvements made in alternate versions of the program, if they
+receive widespread use, become available for other developers to
+incorporate.  Many developers of free software are heartened and
+encouraged by the resulting cooperation.  However, in the case of
+software used on network servers, this result may fail to come about.
+The GNU General Public License permits making a modified version and
+letting the public access it on a server without ever releasing its
+source code to the public.
+
+  The GNU Affero General Public License is designed specifically to
+ensure that, in such cases, the modified source code becomes available
+to the community.  It requires the operator of a network server to
+provide the source code of the modified version running there to the
+users of that server.  Therefore, public use of a modified version, on
+a publicly accessible server, gives the public access to the source
+code of the modified version.
+
+  An older license, called the Affero General Public License and
+published by Affero, was designed to accomplish similar goals.  This is
+a different license, not a version of the Affero GPL, but Affero has
+released a new version of the Affero GPL which permits relicensing under
+this license.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU Affero General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Remote Network Interaction; Use with the GNU General Public License.
+
+  Notwithstanding any other provision of this License, if you modify the
+Program, your modified version must prominently offer all users
+interacting with it remotely through a computer network (if your version
+supports such interaction) an opportunity to receive the Corresponding
+Source of your version by providing access to the Corresponding Source
+from a network server at no charge, through some standard or customary
+means of facilitating copying of software.  This Corresponding Source
+shall include the Corresponding Source for any work covered by version 3
+of the GNU General Public License that is incorporated pursuant to the
+following paragraph.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the work with which it is combined will remain governed by version
+3 of the GNU General Public License.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU Affero General Public License from time to time.  Such new versions
+will be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU Affero General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU Affero General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU Affero General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU Affero General Public License as published
+    by the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU Affero General Public License for more details.
+
+    You should have received a copy of the GNU Affero General Public License
+    along with this program.  If not, see <https://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If your software can interact with users remotely through a computer
+network, you should also make sure that it provides a way for users to
+get its source.  For example, if your program is a web application, its
+interface could display a "Source" link that leads users to an archive
+of the code.  There are many ways you could offer source, and different
+solutions will be better for different programs; see section 13 for the
+specific requirements.
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU AGPL, see
+<https://www.gnu.org/licenses/>.

 ## About Building from Source
 
-We only allow building unmodified (original) source code for public use. `master` is considered **unstable** and we will not provide technical support if such a build doesn't work, so always build from a tag. You can checkout a tag with `git checkout tags/TAGNAME`, where `TAGNAME` is the tag, for example `v1.20`.

You can checkout a tag with `git checkout tags/TAGNAME`, where `TAGNAME` is the tag, for example `v3.4.1`. See [the tags](https://github.com/BeamMP/BeamMP-Server/tags) for possible versions/tags, as well as [the releases](https://github.com/BeamMP/BeamMP-Server/releases) to check which version is marked as a release/prerelease. We recommend using the [latest release](https://github.com/BeamMP/BeamMP-Server/releases/latest).
 
 ## Supported Operating Systems
 
-The code itself supports (latest stable) Linux and Windows. In terms of actual build support, for now we usually only distribute windows binaries and sometimes linux. For any other distro or OS, you just have to find the same libraries listed in the Linux Build [Prerequisites](#prerequisites) further down the page, and it should build fine. We don't currently support any big-endian architectures.

 ## Build Instructions
 
-**__Do not compile from `master`. Always build from a release tag, i.e. `tags/v2.0`!__**
+On Linux, you need some dependencies to **build** the server (on Windows, you don't):
 
-Currently only linux and windows are supported (generally). See [Releases](https://github.com/BeamMP/BeamMP-Server/releases/) for official binary releases. On systems to which we do not provide binaries (so anything but windows), you are allowed to compile the program and use it. Other restrictions, such as not being allowed to distribute those binaries, still apply (see [copyright notice](#copyright)).
+```
+liblua5.3-dev curl zip unzip tar cmake make git g++
+```
 
-### Prerequisites
+You can install these with your distribution's package manager. You will need sudo or need root for ONLY this step.
 
-#### Windows
+The names of each package may change depending on your platform.
 
-Please use the prepackaged binaries in [Releases](https://github.com/BeamMP/BeamMP-Server/releases/).
+If you are building for ARM (like aarch64), you need to run `export VCPKG_FORCE_SYSTEM_BINARIES=1` before the following commands.
 
-Dependencies for windows can be installed with `vcpkg`, in which case the current dependencies are the `x64-windows-static` versions of `lua`, `zlib`, `rapidjson`, `boost-beast`, `boost-asio` and `openssl`.
+You can build on **Windows, Linux** or other platforms by following these steps:
 
-#### Linux / \*nix
+1. Check out the repository with git: `git clone --recursive https://github.com/BeamMP/BeamMP-Server`.
+2. Go into the directory `cd BeamMP-Server`.
+3. Specify the server version to build by checking out a tag: `git checkout tags/v3.4.1` - [Possible versions/tags](https://github.com/BeamMP/BeamMP-Server/tags)
+4. Run CMake `cmake -S . -B bin -DCMAKE_BUILD_TYPE=Release` - this can take a few minutes and may take a lot of disk space and bandwidth.
+5. Build via `cmake --build bin --parallel --config Release -t BeamMP-Server`.
+6. Your executable can be found in `bin/`.
 
-These package names are in the debian / ubuntu style. Feel free to PR your own guide for a different distro.
+When you make changes to the code, you only have to run step 4 again.
+### Building for FreeBSD
+Building is only supported for major release branches of FreeBSD that are currently not EOL. The build process is the same as on Linux, although build dependencies can be universally installed from ports via pkg:
+```
+pkg install git cmake-core zip bash devel/ninja devel/pkgconf lua53
+```
+After installing the necessary build dependencies, follow the Linux build instructions beginning from step 3. Beware that running the initial cmake command will compile vcpkg from source, as vcpkg has no native FreeBSD port - this may take some time.
 
-- `git`
+On systems with a single logical CPU core, `make` may fail to build the server when using the `--parallel` option when calling CMake. If you see error messages related to make, simply omit the `--parallel` from the command: `cmake --build bin --config Release -t BeamMP-Server`.
-- `make`
-- `cmake`
-- `g++`
 
-  Must support ISO C++17. If your distro's `g++` doesn't support C++17, chances are that it has a `g++-8` or `g++-10` package that does. If this is the case. you just need to run CMake with `-DCMAKE_CXX_COMPILER=g++-10` (replace `g++-10` with your compiler's name).
+### Runtime Dependencies
-- `liblua5.3-dev` 
 
-  Any 5.x version should work, but 5.3 is what we officially use. Any other version might break in the future.
+These are needed to *run* the server.
-  You can also use any version of `libluajit`, but the same applies regarding the version.
-- `libz-dev`
-- `rapidjson-dev`
-- `libopenssl-dev` or `libssl-dev`
 
-**If** you're building it from source, you'll need `libboost1.70-all-dev` or `libboost1.71-all-dev` or higher as well.
+Debian, Ubuntu and friends: `liblua5.3-0`
 
-### How to build
+Other Linux distros: `liblua` of *some kind*.
 
-On windows. use git-bash for these commands. On linux, these should work in your shell.
+Windows: No libraries.
 
-1. Make sure you have all [prerequisites](#prerequisites) installed
+## Support
-2. Clone the repository in a location of your choice with `git clone --recursive https://github.com/BeamMP/BeamMP-Server`. Now change into the cloned directory by running `cd BeamMP-Server`.
+The BeamMP project is supported by community donations via our [Patreon](https://www.patreon.com/BeamMP). This brings perks such as Patreon-only channels on our Discord, early access to new updates, and more server keys. 
-3. Checkout the branch of the release you want to compile (`master` is often unstable), for example `git checkout tags/v1.20` for version 1.20. You can find the latest version [here](https://github.com/BeamMP/BeamMP-Server/tags).
-4. Run `cmake .` (with `.`)
-5. Run `make`
-6. You will now have a `BeamMP-Server` file in your directory, which is executable with `./BeamMP-Server` (`.\BeamMP-Server.exe` for windows). Follow the (windows or linux, doesnt matter) instructions on the [wiki](https://wiki.beammp.com/en/home/Server_Mod) for further setup after installation (which we just did), such as port-forwarding and getting a key to actually run the server.
-
-*tip: to run the server in the background, simply (in bash, zsh, etc) run:* `nohup ./BeamMP-Server &`*.*
