Release Notes
webpack/webpack

Performance
- fix missing increment in sorting optimization from last release
v5.38.0
Features
-
new URL("data:...", import.meta.url)
is now supported - add
module.rules[].scheme
as condition to match the request scheme (likedata
,http
, etc.)
Bugfixes
- fix tracking of changes and removals during watching in some edge cases
- fix incorrect renaming of class fields in concatenatenated modules
- fix crash in HMR when removing runtimes from the compilation
Performance
- lazy import some internal modules only when used
- allow unsafe caching of the entrypoint
- improve performance of sorting exports info map
- update to latest webpack-sources for improved source map performance
v5.37.1
Bugfixes
- When using multiple configurations in watch mode and calling
Watching.invalidate
,dependencies
andparallelism
of the config array is now respected correctly - Fix a crash when accessing the
stats
after the next compilation has started - fix collecting changes when using
Watching.suspend
- fix schema of
RuleCondition.not
and allow passing a condition directly instead of only an array
Developer Experience
- typings accept a ReadonlyArray of configurations now
Contributing
- fix coverage reporting for child processes
- remove outdated loader from readme
v5.37.0
Features
- add
output.trustedTypes
Bugfixes
- fix inclusion of too many chunk in the filename function when using
dependOn
- allow errors to be
null
in fs callbacks
Developer Experiences
- make ESM tracking info message less verbose
- add typings for loaders
v5.36.2
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
- Using
- fix a problem when chained dependOn, which causes too many modules being included in entrypoints
v5.36.1
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
Features
- add support for class fields (stage 4)
Performance
- improve (de)serialization performance of dependency locations
v5.35.1
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

v5.35.0
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 wantallowCollectingMemory: false
and for watch builds you probably wantallowCollectingMemory: true
. It defaults to false in production mode and true in development mode.

resolve.extensions
and handle them in this order - add
pnpapi
as builtin external when usingtarget: "node"

target: "node"
- fix deprecation message from LimitChunkCountPlugin

Memory
- eliminated some memory leaks

- This fixes a problem with concatenated modules in builds with multiple runtimes and force-merged shared chunks
- ensure that entrypoints are always re-executed when HMR-updated
