February 2026: Delivered targeted updates to saw-script and cryptol that bolster tooling interoperability and user experience. Key features delivered include a changelog update to reflect mir-json schema v8 support in saw-script and a VSCode extension bump to 0.1.3 for Cryptol. Major bugs fixed include corrections to Cryptol Language Server documentation typos for improved clarity. Overall impact: enhanced developer onboarding, reduced ambiguity around schema compatibility and extension behavior, and smoother integration with latest editor tooling. Technologies demonstrated: changelog governance, documentation quality assurance, release/version management, and cross-repo collaboration.

January 2026 monthly summary focusing on release engineering and cross-repo alignment across Crucible, Cryptol, and SAW-script. Delivered release readiness for Crucible 0.9 / Crux 0.12, Cryptol 3.5.0, and SAW-script 1.5, with coordinated submodule updates, dependency bumps, and versioning to support post-release development. Aligned test baselines for Crux-MIR and updated SAW baselines to reflect code changes. Implemented tooling compatibility improvements (LLVM-Pretty 21, crypton workaround, and parser AST tweaks). Resolved key bugs including a dependency conflict (dialing back parameterized-utils) and syntax/formatting cleanups. Documentation and release notes updated; lockfiles refreshed to ensure reproducible builds and clear post-release development paths.
