Microsoft ships TypeScript 7.0 Beta featuring a native Go port of the compiler and language service, delivering often 10x faster builds, reduced memory use, and parallelized type-checking for large codebases.

The fourth release candidate for Elixir 1.20 lands ahead of a planned May 2026 final, capping the largest type-system milestone in the language's history with whole-function inference, cross-clause analysis, and a roughly 10% compiler speedup.

Gleam v1.16.0, released April 24, adds JavaScript source maps, package-wide parallel error reporting, and a roughly 30% speedup for single-character string-prefix matching on JavaScript.

Crystal 1.20.0 lands with a Linux io_uring event loop, CPU-feature targeting via @[TargetFeature], a new array-based Process API, kernel TLS, and a fix for an HTTP request-smuggling vulnerability.

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.

Microsoft has released TypeScript 6.0, the final major version built on the original JavaScript compiler codebase. The release introduces sweeping default changes, deprecates legacy module formats, and adds a migration flag to prepare codebases for TypeScript 7.0, which will be built entirely in Go.

LLVM 22.1 landed on March 11 with distributed ThinLTO, C2y named loops and defer, Armv9.7-A assembly, and AMD Zen 4 optimizations as the toolchain removes Google NaCl.
