We have the following branches in our repository: `v4.2` and `v5.0`. Each branch has two builds (for linux and windows).
When a PR is merged to the `v4.2` branch, the related webhook triggers all of the builds for both `v4.2` and `v5.0`:
This is how the `Testsv42_Linx64` build is configured. The rest of the builds are configured similarly.
Additional note: the v5.0 branch contains some commits from the v4.2 branch - the v4.2 branch is merged to v5.0 once in a while.
