* If this is an RC1 (first Release Candidate) build, create a new branch `release/nn` where `nn` is the major version number, then apply changes similar to [PR#9573](https://github.com/OpenTTD/OpenTTD/pull/9573). You also need to forwardport the changelog, as in [PR#10113](https://github.com/OpenTTD/OpenTTD/pull/10113).
* Update the version in `CMakeLists.txt` in the master branch, heading for the next major release, e.g. from 14.0 to 15.0.
* Add a new (empty) AI compatibility script in `bin/ai/`
* Add the new version to CheckAPIVersion in `src/ai/ai_info.cpp` and `src/game/game_info.cpp`
* Add the new version to `src/script/api/ai_changelog.hpp` and `src/script/api/game_changelog.hpp`
* Update the version of regression in `bin/ai/regression/regression_info.nut`
* Add the new version to `ApiVersions` in `src/ai/ai_info.hpp` and `src/game/game_info.hpp`.
* Add the new version to `src/script/api/ai_changelog.hpp` and `src/script/api/game_changelog.hpp`.
* Update the version of regression in `bin/ai/regression/regression_info.nut`.
* Add a new (empty) AI compatibility script in `bin/ai/` and `bin/game/` for the version of the branch.
* Add a note to `src/saveload/saveload.h` about which savegame version is used in the branch.
* If this is a later RC or release build and the release branch already exists, you'll need to backport fixes and language from master to this branch, which were merged after the branch diverged from master. You can use these two helper scripts: https://github.com/OpenTTD/scripts/tree/main/backport
