May 1, 2026May 2026 – Rescript watch/build reliability enhancements in rescript-lang/rescript. Delivered three core improvements to stabilize long-running watch cycles, improve test reliability, and ensure deterministic build behavior. Outcomes include fewer race conditions, cleaner test harnesses, and more reproducible incremental builds, backed by changelog/API updates and clear commit-level traceability. What changed (highlights): - Build Locking and Synchronization for Reliable Rewatch/Watch Builds: hardened build lock acquisition, extended cleanup, and API/changelog accommodations to prevent interference across watch startup, incremental builds, and rewatch operations. Commits include 277870628ca9a570b4097d2389eb37ca1ff2cf59; e8cdc22138854e35bdcf46e6bc37d018be1e641d; 93674d2aecdd404d8cb5e827e526e78cdefb0382; 2d5a0002e9ebfeed64c0277f0c0d827b35cfc2b6; acca308f52a27e097ff4cc9d3b5c6d1dce08ae6c. - Reliable Test Watcher Lifecycle (Bug): ensure test watchers exit cleanly after execution to improve test reliability and eliminate stray processes. Commit: dee432cce09a56cefb0a2230ed100dfad173d113. - Build Correctness Enhancements: Unified Timestamps and Deterministic Warning Replay: unify module timestamps to a single value per compile pass and guarantee deterministic replay of stored warnings for skipped modules. Commits: 88136c0e8d217cf2c5b0a989e98f0109b510ff64; 56d4ed5fe678bef15e9828fe60e2e91643e589ed. Impact and value: - Stability: Reduced race conditions and flaky incremental builds; cleaner test runs without orphaned watchers. - Reproducibility: Deterministic warning replay and unified timestamps improve dependency expiry detection across dev and CI environments. - Efficiency: Faster triage and reduced debugging time thanks to reliable builds and predictable test behavior. - Developer experience: Clear changelog/API touchpoints support better onboarding and future changes.

Dec 1, 2025During December 2025, the Rescript toolchain saw notable improvements in developer experience, parser robustness, and release readiness. Key changes include a cross-module Stdlib ignore helper, robust GlobalThis-based shadowing fixes for @val and @scope, improved extern signature handling through arity normalization for abstract aliases, enhanced arity detection for arrow functions returning nested generics, and clearer JSON parsing error messages with key-path context. These changes together reduce boilerplate, surface actionable errors sooner, and strengthen language/tooling reliability ahead of the 12.x release cycle.
