 ### Added
 * due to github runner changes, the regular mac build is now arm64, so we added support for intel x86 apple build in nightlies and releases (via separat artifact)

+* support help popup display viewing progress[[@wugeer](https://github.com/wugeer)](https://github.com/extrawurst/gitui/pull/2388))
