Release Notes

webpack/webpack

### [`v5.30.0`](https://togithub.com/webpack/webpack/releases/v5.30.0) [Compare Source](https://togithub.com/webpack/webpack/compare/v5.29.0...v5.30.0) ### Features - add GC to memory cache - opt-in via `cache.maxGenerations` when `cache.type: "memory"` - default for `cache.type: "filesystem"` and `mode: "development"` - configure via `cache.maxMemoryGenerations` when `cache.type: "filesystem"` - Generations = Rebuilds - add GC for untouched filesystem cache files - allow to configurate GC for the filesystem cache via `cache.maxAge` - allow to disable memory cache when using the filesystem cache with `cache.maxMemoryGenerations: 0` - Caches will be cleared on Compiler close resp Cache shutdown (after persisting for the filesystem cache) ### Bugfixes - add a few workarounds for v8 bug that causes memory leaks in optimized code (only partially fixes it) - after serializing filesystem no longer keeps cache items in memory, instead it will read them from disk again when accessed GC = Garbage Collection
