Release notes

Sourced from webpack's releases.

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
