Highlights

Note: 3.119.3 shipped only as previews and was never released as a stable package. All of the work below rolled up into 3.119.4.

This preview cycle focused on native dependency updates and stability fixes. libwebp, brotli, libexpat, and libpng were all bumped to their latest versions, and Spectre mitigations landed for both the Windows and Linux native libraries. Two community contributors — ❤️ @sshumakov and ❤️ @Copilot — contributed the security hardening and an AoT crash fix.
