Release notes

Sourced from webpack's releases.

v5.108.4

Patch Changes

• Speed up non-CSS-Modules parsing by not building unused selector AST nodes. (by @​alexander-akait in #21324)

• Speed up non-CSS-Modules CSS parsing by dropping value tokens nothing reads. (by @​alexander-akait in #21324)

• Resolve HTML asset URLs against the document <base href>. (by @​alexander-akait in #21329)

• Add HTML integration tests: generateError output, ignored src, null-char parse. (by @​aryanraj45 in #21328)

• Reduce CPU and memory overhead of HTML and CSS parsing and code generation. (by @​alexander-akait in #21332)

• Reduce HTML parser memory and CPU by skipping unused AST nodes. (by @​alexander-akait in #21323)

• Reduce HTML parser memory by storing the AST in struct-of-arrays form. (by @​alexander-akait in #21331)

• Key the provided-exports cache on a lazy barrel's still-lazy re-export targets. (by @​hai-x in #21326)

• Default output.globalObject to globalThis for universal targets. (by @​alexander-akait in #21314)

• Pass through new URL(...) directory references instead of resolving them. (by @​alexander-akait in #21312)

v5.108.3

Patch Changes

• Speed up CSS parsing and reduce CSS AST node memory. (by @​alexander-akait in #21285)

• Fix HMR codegen crash for harmony accept with unresolved imports. (by @​xiaoxiaojx in #21302)

• Match harmony accept dependencies by module reference so HMR codegen handles imports without a module or chunk id. (by @​alexander-akait in #21303)

v5.108.2

Patch Changes

• Fix lazy barrel deferral of ungrouped side-effect imports. (by @​hai-x in #21291)

v5.108.1

Patch Changes

• Fix invalid property access for escaped namespace imports with multi-character mangled export names. (by @​xiaoxiaojx in #21280)

• Add frames to ProfilingPlugin TracingStartedInBrowser event so the trace loads in Chrome DevTools. (by @​alexander-akait in #21269)

v5.108.0

Minor Changes

• Treat top-level await and import.meta as ES module markers, matching Node.js syntax detection so no explicit module type is needed. (by @​alexander-akait in #21218)
