v5.0.0-beta.4

Features

• add dependencies to ProgressPlugin, enabled by default
• add support for npm fund

Persistent Caching

• make SourceMap and source names in NormalModule context-independent
• upgrade webpack-sources
  • use only public methods for serialization
• add caching support for SourceMapDevToolPlugin (all non eval based source-map devtools)

Bugfixes

• different resolve options are not cached separately
• fix throttling of ProgressPlugin output

Performance

• resolver cache respects resolve.cacheWithContext now, which defaults to false
• merge concurrent resolve request in cache
• newly created file system snapshots are considered as valid now
• avoid creating arrays in ModuleGraph getConnections
• allocate lazily:
  • ModuleGraphConnection.explanations
  • ChunkGraphModule.entryInChunks, ChunkGraphModule.runtimeInChunks
  • Module.warnings, Module.errors
  • NormalModule._sourceSizes, NormalModule.presentationalDependencies
  • Module.factoryMeta
  • ModuleGraphModule.outgoingConnections
• omit unneeded process.nextTicks
• remove return value of ChunkGraph.connectChunkAndModule to skip check
• upgrade webpack-sources
  • cache utf-8 to buffer conversions and reverse
  • cache string to json conversions and reverse
• ProgressPlugin
  • fix throttling of output
• AsyncQueue
  • use setImmediate instead of process.nextTick to schedule the next task
    • This keeps event loop spinning and improved build speed
• hoist some expressions/RegExps

Persistent Caching

• nested plain object are (de)serialize in one pass
• print warning when big strings are serialized
• upgrade webpack-sources
  • avoid serializing strings, prefer Buffers
• allow lazy stringified etags for identity check for memory cache
