# v2.4.0
- CHANGED entire plugin Lua implementation (rewrite)
- CHANGED moved *almost all* functions into MP.\*
- CHANGED console to use a custom language (type `help`, `list`, or `status`!)
- CHANGED all files of a Lua plugin to share a Lua state (no more state-per-file)
- ADDED many new Lua API functions, which can be found at <https://wiki.beammp.com/en/Scripting/functions>
- ADDED Commandline options. Run with `--help` to see all options.
- ADDED HTTP(S) Server (OpenAPI spec coming soon!)
- ADDED plugin directories to `package.path` and `package.cpath` before `onInit`
- ADDED ability to add `PluginConfig.toml` to your plugin folder to change some settings
- ADDED ability to share a lua state with other plugins via `StateId` setting in `PluginConfig.toml`
- ADDED ability to see name-to-thread-ID association in debug mode
- ADDED dumping tables with `print()` (try it with `print(MP)`)
- ADDED `MP.GetOSName()`, `MP.CreateTimer()`, `MP.GetLuaMemoryUsage()` and many more (see <https://wiki.beammp.com/en/Scripting/functions>)
- ADDED `MP.Settings` table to make usage of `MP.Set()` easier
- ADDED `FS.*` table with common filesystem operations
- FIXED i/o thread spin when stdout is /dev/null on linux
- FIXED removed extra whitespace infront of onChatMessage message
# v2.3.3
- CHANGED servers to be private by default

**If** you're building it from source, you'll need `libboost1.70-all-dev` or `libboost1.71-all-dev` or higher as well.
If you can't find this version of boost (only 1.6x, for example), you can either update to a newer version of your distro, build boost yourself, or use an unstable rolling release (like Debian `sid` aka `unstable`).
In the end you should end up with a command something like this:
```sh
sudo apt install git make cmake g++-10 liblua5.3 libz-dev rapidjson-dev libopenssl-dev
```
In the end you should end up with a command something like this:
```sh
sudo apt install git make cmake g++-10 liblua5.3 libz-dev rapidjson-dev libopenssl-dev
```
### How to build
On windows, use git-bash for these commands. On Linux, these should work in your shell.
1. Make sure you have all [prerequisites](#prerequisites) installed
2. Clone the repository in a location of your choice with **`git clone --recurse-submodules https://github.com/BeamMP/BeamMP-Server`**. Now change into the cloned directory by running `cd BeamMP-Server`.
2. Clone the repository in a location of your choice with `git clone --recurse-submodules https://github.com/BeamMP/BeamMP-Server`.
3. Ensure that all submodules are initialized by running `git submodule update --init --recursive`. Then change into the cloned directory by running `cd BeamMP-Server`.
4. 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).
5. Run `cmake .` (with `.`)
5. Run `cmake . -DCMAKE_BUILD_TYPE=Release` (with `.`)
6. Run `make`
7. 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.

USAGE:
BeamMP-Server [arguments]
ARGUMENTS:
--help
Displays this help and exits.
--config=/path/to/ServerConfig.toml
Absolute or relative path to the
Server Config file, including the
filename. For paths and filenames with
spaces, put quotes around the path.
--working-directory=/path/to/folder
Sets the working directory of the Server.
All paths are considered relative to this,
including the path given in --config.
--version
Prints version info and exits.
EXAMPLES:
BeamMP-Server --config=../MyWestCoastServerConfig.toml
Runs the BeamMP-Server and uses the server config file
which is one directory above it and is named
'MyWestCoastServerConfig.toml'.
