Sep 1, 2025September 2025, cloudflare/workerd: Implemented V8 deprecation compatibility update in the worker runtime by refactoring internal fields handling and embedder data access. This change replaces a single SetAlignedPointerInInternalFields call with two SetAlignedPointerInInternalField calls and adds a new type tag argument to SetAlignedPointerInEmbedderData, addressing deprecation warnings in recent V8 releases and improving type safety and future compatibility. The work reduces runtime warnings, simplifies migration paths for newer V8 versions, and strengthens the runtime's embedder data interface.
