Happy New Year!

It has been 203 days since the release of git gud, and Im incredibly grateful for how many people have played and enjoyed the game. Hopefully, everyone has picked up a new Git command or two along the way as well.

This update is a big one, the largest so far. One of the most important additions is the new Content Pack system, which is the plan going forward for continued development. Content packs will introduce new sets of challenges built around themed, real-worldstyle scenarios. Each pack will be low cost (around a dollar or two) and will go on sale whenever the base game does. Its important to me to keep git gud accessible while still being able to justify the time required to add meaningful new content and improvements. The first content pack will be releasing shortly alongside an introductory sale.

You may notice that this update includes a lot of changes. While some of that work was driven by the first content pack, I also added 246 new unit and integration tests. This surfaced a number of edge cases and areas that needed improvement, and it should significantly reduce the chance of regressions, particularly cases where previously valid challenge solutions would break after a major update.

git gud now includes support for git-filter-repo. I originally avoided this since it isnt part of core Git, but Ive listened to the community feedback encouraging its use over [c]git filter-branch[/c]. Existing challenges will continue to accept either tool as valid solutions, but an upcoming content pack introduces scenarios where company policy explicitly forbids [c]filter-branch[/c].

Ive also made another pass at tab completion. This iteration should be a noticeable improvement and closer to real-world behavior across common terminal environments.

Finally, macOS support is now included. This has been available in the development branch for about a week with no reported issues so far. If any problems do come up, please report them in the Steam Discussions bug reporting forum so they can be addressed quickly.

As a small but important note: going forward, each release will be archived as a beta branch. If you run into issues with [c]1.5.0[/c], youll be able to revert to [c]1.4.2[/c] while waiting for fixes. This was requested by a university that uses git gud in coursework and needs tighter control over version upgrades.

Thanks again to everyone for the continued support,\nSky
