Release by release

  1. 30.5.2

    18 Sep 20261 new · 3 fixes
    • new

      @jest/transform: Strip TypeScript types with Node when no transformer claims a .ts, .mts or .cts file

    • fixed

      jest-core, jest-haste-map, jest-transform: Keep require('../package.json') external when bundling, so jest --version and the transform and haste-map cache keys report the released version instead of the previous one

    • fixed

      jest-each: Escape a table row's keys before building the $variable interpolation RegExp, so a column name such as count(*) no longer fails the whole table with Invalid regular expression, and a . or | in a column name is matched literally

    • fixed

      @jest/source-map: Resolve absolute Windows paths in a source map's sources and sourceRoot again, instead of appending them to the transformed file's directory

  2. 30.5.1

    1 Sep 20265 fixes

      jest-config: Don't warn about global-only options in the config that supplies the global config - the root config a project resolves to, or the first entry of --projects when no root config is passed

    • fixed

      jest-config, jest-types: Stop accepting reporters, coverageReporters, workerIdleMemoryLimit, cwd and runnerOptions in a project config - they were silently ignored, and now warn like the other global-only options

    • fixed

      jest-config, jest-validate: Warn about maxWorkers and coverageThreshold in a project config instead of dropping them without a word

    • fixed

      jest-resolve: Match moduleNameMapper patterns against the specifier as written again (reverting #16390)

    • fixed

      jest-runtime: Resolve package imports specifiers like #dep under ESM again
