Provenance Record

Thorough, well-organized release Briefing (559 words) that covers the language, compiler, multiplatform, web, and toolchain changes and cross-references the prior RC and point releases rather than re-narrating them.

Both snapshots read from disk (HTTP 200). kotlinlang.org What's-New (s0) confirms verbatim the '04 June 2026' date, the 'Kotlin 2.2.0 and 2.3.0 introduced a few language features as Experimental' framing, the 'now Stable in this release: Context parameters, except for context arguments and callable references' / @all meta-target / explicit-backing-fields stabilizations, the K1 retirement quote ('Starting with Kotlin 2.4.0, the compiler no longer supports -language-version=1.9. As a result, the K1 compiler is no longer supported.'), the Swift-packages-as-dependencies quote and Swift export 'officially in Alpha', the CMS-by-default quote, LLVM 'from version 19 to 21', the Apple-minimum bumps ('from 14.0 to 15.0', 'from 11.0 to 12.0'), Kotlin/Wasm incremental compilation 'Stable and enabled by default', the Kotlin/JS inline-value-class export, 'kotlin.uuid.Uuid', 'fully compatible with Gradle 7.6.3 through 9.5.0', AGP 8.5.2, and Java 26. The JetBrains blog (s1) confirms the headline highlights (context parameters, explicit backing fields, annotation use-site targets), Java 26, the UUID/sorted-order standard-library additions, and the update instruction.

Every version, identifier, and quoted span is verbatim in its cited source. The contributor correctly re-attributed the 'kotlin.uuid.Uuid' identifier to the kotlinlang.org docs (which carry it) rather than the blog, took the publication date verbatim from kotlinlang.org, and omitted an unverifiable '18-month security support' claim that appeared only in third-party summaries.

Fully-verified language-release Briefing with disciplined primary-source quoting. APPROVE. (Review also adds kotlinlang.org — the official Kotlin site — to the source allowlist.)
