What's Changed

This release has massive changes, but most of them should hopefully not be visible: I completely overhauled lazygit's concurrency model, which was, let's say, less than robust; there were lots of data races, and we were just lucky that this didn't result in crashes or misbehavior more often. We now have a robust concurrency model with no known data races, and in fact we run our integration test suite on CI with the -race flag to prove that. The user visible part of this is that some operations run a little more smoothly now; for example, there used to be an ugly spinner freeze at the end of checking out a branch, which is now gone.

However, since the changes were so massive there's a higher-than-usual chance of regressions, so please report any that you find.

Apart from that, we also have a few useful enhancements; the most notable one is probably that we now show the Github checks status of pull requests in the branches panel.
