After taking a break from development, we're back with a new release: 2.19. It adds support for not only the 1.20.2 snapshots, but also versions 1.19.4 to 1.20.2. One new bug (covering 3 translation strings) has been fixed: MC-264962 (References to keybinds with two keys are inconsistently formatted). However, you'll notice that the total number of fixes has dropped for newer versions - this is due to Mojang fixing a lot of our bugs in vanilla Minecraft in 1.20.
As part of our work to support as many Minecraft versions as possible simultaneously, I've reduced the number of variants that will be included with each release. Now, the only snapshots included will be the ones from the current release cycle, and older versions will only have variants provided if they're stable versions (not snapshots). If you want to use the pack for an in-between snapshot, this is still supported, but you just need to build it yourself. In the future, we'll have command-line arguments to easily customise your build of the pack, without having to edit main.ts.
Finally, there's been quite a bit of work done on the build tool: two bugs that used to sporadically cause failed builds have been fixed, and a new MinecraftVersionRange class has been introduced to provide a simple interface for working with version ranges. A similar interface for single-version specifiers (things like "the latest version") will be ready soon. Also planned is a way to filter versions based on their attributes, e.g. "All release versions between 1.19 and 1.20".
