td.ArrayList` (so the change was in standard library code rather than the language). Those default values had actually already been deprecated (with intent to remove) for around a year, so this wasn't exactly a new change either. As another example, Andrew has updated Awebo (https://codeberg.org/awebo-chat/awebo), a text and voice chat application, to the new version of Zig. Across Awebo's entire dependency tree (which includes various packages for graphics, audio, and probably some other stuff), the full set of necessary changes was: * Same as above, change `.{}` to `.empty` in a few places, due to removal of deprecated defaults * Add one extra `comptime` annotation to logic which was constructing an array at comptime * Append `orelse @alignOf(T)` onto an expression to deal with a newly-possible `null` case These are all trivial fixes which Zig developers would be able to do pretty much on autopilot upon seeing the compile errors. So, while there were a handful of small breaking changes, they don't seem to me like a particularly big deal (for a language where some level of breakage is still allowed). The main thing this PR achieved was instead a combination of bugfixes, and enhancements to existing features (particularly incremental compilation).
