Tailwind v4 sorting now uses property signatures (
669a96f)
The useSortedClasses v4 sorter now compares candidates by Tailwind’s property signature, not just property index/count. That aligns Biome’s ordering with Tailwind’s own tie-break rules for broader utilities and arbitrary-property cases, reducing mis-sorts in the v4 preset.
Structured type-inference profiling added to biome check (
55c2427)
The CLI now wires in a dedicated type-inference profiler path alongside existing rule profiling, with a new check-command option and execution hooks to collect and drain snapshots. This makes it possible to measure inference work separately, which should help diagnose performance regressions and hotspots more precisely.
WeakMap global type is now generated, not hand-maintained (
1258023)
WeakMap was migrated into generated global type data, keeping its T, U type parameters and adding generator validation to enforce the expected shape. This reduces manual divergence in the predefined globals model and makes future codegen changes safer.
Other misc changes
- Fixed a bench build issue in HTML handling (4fb9d39).
- Dependency bumps:
regex,proc-macro2,libc,jiff. - Minor docs and internal cleanup around HTML embeds and codegen fixtures.
