Release note

Performance

  • #2395 - perf-benchmarks: Replaces the Best performance tests with Tachometer.

  • #2428 - perf-benchmarks: Adds bundlesize package to check that the JavaScript bundle sizes of the LWC repository don't exceed a given threshold.

  • #2405 - engine-core: Changes the template compilation of text nodes (with interpolated expressions), so it only generates one vnode.

  • #2426 - synthetic-shadow: micro-optimization for patchedAddEventListener. It avoids cloning an Array of arguments every time addEventListener is called.

Bug fixes

  • #2393 - synthetic-shadow: Fixes incorrect behavior when light DOM components are used with synthetic shadow DOM (#2386).
