What changed in each release, and what testing wowlua against real addons taught us.
M8, the standard library: wowlua: modules written in wowlua, typed, and tested in game on WoW: Forever. examples/core-demo uses no third-party libraries for its events, saved variables, settings, minimap button, keybindings and comms.
Release notes on the changelog.
M7's exit criterion is met: SuuUI, a WoW: Forever addon adopted with wowlua init, was published from CI to CurseForge, Wago and GitHub with one tag push.
M7, optimization and publishing: bundled, minified and optimized release builds, and wowlua publish to four addon sites.
wowlua init --from-pkgmeta adopts a packager project. Thirty-six addons, packaged by the packager and built by wowlua at pinned commits, load identical code in every flavor and client locale.
M6, the package manager. Addons built with the BigWigs packager migrate with wowlua init --from-pkgmeta and build the same, checked on thirty-six addons.
M5, debugging: wowlua:debug, wowlua:reflect and wowlua:log; profiling, tracing and runtime checks; the in-game dev window (/wl); wowlua trace.
M4, the type checker: basic and strict mode, generics, narrowing, flavor guards, wowlua lint and wowlua fix.
M3: classes, widget classes, enums and decorators, and the standard-library infrastructure.
M2: lowering of syntax sugar and modules.
M1: the parser and the emitter.
M0, the foundation: an existing Lua addon builds and installs from a wowlua.json, with generated TOCs for several flavors.
