Ensure all changes are on the `master` branch.\n1. Ensure the version number is correct in `RLBotCS/Main.cs`.\n1. In GitHub’s UI, create and publish a new release (this will create the tag for you).\n   - Use the next version number, e.g. `v1.0.0`.\n   - Mark the release as **pre-release** initially.\n1. Wait for the GitHub Actions workflow to build the release and upload it to the release page.\n1. After the workflow finishes, edit the release and set it as the **latest release**.\n\n### Release rollbacks\n\nInstances of RLBot download the version tagged as the latest release. To rollback a release or otherwise change the version being distributed, simply **mark any other verison at the latest release** in GitHub's UI.\n\n## Maintenance\n\n### Formatting\n\nThis project uses the CSharpier formatter. You can run it with `dotnet csharpier format .`\n\n### Flatbuffers\n\nThe Core project uses flatbuffers, which involves generating C# code based on a specification\nfile called `rlbot.fbs`. Find this in `./FlatBuffer` after it's been generated.\n\nThe [flatbuffers-schema](https://github.com/RLBot/flatbuffers-schema) submodule should be kept update to date:\n\n- `cd flatbuffers-schema`\n- `git checkout main`\n- `git pull`\n\nThe needed Flatbuffers code is automatically generated upon compilation of the project.\n\n### Bridge\n\nThe `Bridge.dll` file in `RLBotCS/lib` is built from a _closed-source_ repository due to legal reasons.\nIt is maintained by RLBot developers who have signed an agreement with Psyonix to keep it private.\n\nThe dll file is platform-independent and works for building the project on both Windows and Linux.\n\n### rl_ball_sym\n\nThe native binaries that live in `RLBotCS/lib/rl_ball_sym` generate the ball prediction that core then distributes to bots \u0026 scripts that request it.\nThe `dll`/`so` are dynamically loaded at run time while developing core, and the `a`/`lib` files are statically linked during publishing.\n\nAll source code and releases for building the dlls can be found at \u003chttps://github.com/VirxEC/rl_ball_sym_dll\u003e but the core of the code is a library that's published for anyone's use at \u003chttps://crates.io/crates/rl_ball_sym\u003e.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Frlbot%2Fcore","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Frlbot%2Fcore","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Frlbot%2Fcore/lists"}
