• [jest-runtime] Validate TC39 import attributes (with { type: 'json' }) on ESM imports (#​16127)

• [jest-config] Allow collectCoverage and coverageProvider in project config without a validation warning (#​16132)

• [jest-environment-node] Fix --localstorage-file warning on Node 25+ (#​16086)
• [jest-reporters] Apply global coverage threshold to unmatched pattern files in addition to glob/path thresholds (#​16137)
• [jest-reporters, jest-runner, jest-runtime, jest-transform] Fix coverage report not showing correct code coverage when using projects config option (#​16140)
• [jest-runtime] Resolve expect and @jest/expect from the internal module registry so test-file imports share the same JestAssertionError as the global expect (#​16130)
• [jest-runtime] Improve CJS-from-ESM interop: __esModule/Babel default unwrap, broader named-export coverage, and shared CJS singleton across importers (#​16050)
• [jest-runtime] Load .js files with ESM syntax but no "type":"module" marker as native ESM (#​16050)
• [jest-runtime] Extend the .js-with-ESM-syntax fallback to require() on Node v24.9+ - falls back to require(esm) when the CJS parser rejects ESM syntax (#​16078)
• [jest-runtime] Fix deadlocks and double-evaluation in concurrent ESM and wasm imports (#​16050)
