Kotlin 2.3.20 ships name-based destructuring, default Build Tools API on Kotlin/JVM, Gradle 9.3.0 compatibility, and Wasm string performance gains of up to 4.6 times.

Rust 1.95 lands with a new `cfg_select!` macro, `if let` guards in `match`, stabilized APIs, and a stricter stance on custom target JSON on stable.

SQLite 3.52.0, expected to release around March 11, 2026, will add ALTER TABLE support for NOT NULL and CHECK constraints, a new Query Result Formatter for the CLI, two new JSON array functions, and query planner improvements.
