Features

• add output.trustedTypes

Bugfixes

v5.36.2

Compare Source

Bugfixes

• correctly handle errors thrown during parser/generator creation
  • e. g. validation errors for asset module options
• use a better automatic runtime name for workers
  • not too long to cause filename problems
• no longer assume assets do not get removed when the compiler is running
  • Using output.clean is against this assumption
  • It fixes a bug where assets are missing, when removed and readded to the compilation
• fix a problem when chained dependOn, which causes too many modules being included in entrypoints

v5.36.1

Compare Source

Performance

• add cache.profile (type: "filesystem" only) flag for more info about (de)serialization timings
• avoid complex "by exports" splitting for splitChunks in development mode
• faster hashing for the common case
• improve algorithmic complexity for merging InitFragments to solve performance in an edge case

v5.36.0

Compare Source

Features

• add support for class fields (stage 4)

Performance

• improve (de)serialization performance of dependency locations

v5.35.1

Compare Source

Bugfixes

• fix an __webpack_exports__ is not defined error with some library types

performance

• improve stats grouping performance
• improve providedExports analysis performance
• improve hashing performance
• lazy merge dependencies from creating context modules
• improve dependency parents access performance

v5.35.0

Compare Source

Bugfixes

• fix handling of build dependencies with # in path

Performance

• improve memory usage when using the filesystem cache

When reading a file into a Buffer and picking smaller slices of the Buffer
the small slices still keep a reference to the large original Buffer.
The leads to increased memory usage. A fix would be to clone the slice into
a smaller Buffer when wasting too much memory, but this has a performance cost.
There is now a new option cache.allowCollectingMemory which controls that.
For one-off builds you probably want allowCollectingMemory: false and
for watch builds you probably want allowCollectingMemory: true.
It defaults to false in production mode and true in development mode.

Compare Source

Performance

• Improved performance of ProgressPlugin
• Improved performance of chunk graph generation
  • This can boost performance when many chunks are used, especially incremental build performance
  • Modules from parent chunks are now tracked during chunk graph generation, which allows to skip these modules in async chunks. This often renders optimization.removeAvailableModules unneeded, expect in scenarios where chunks are merged during optimization.
• optimization.removeAvailableModules is now disabled in development mode by default
  • optimization.removeAvailableModules will be disabled for all modes in next major release, feel free to disable it in production too if you want extra performance.
