Good morning, it's November 1st, 2026.
The throughline is reliability in hostile environments — Windows terminals, locked files, and strict security policies — alongside a major performance push in schema validation.
First, terminals. A cluster of work tackles stray color codes ending up in the prompt. On Windows, the compatibility layer answers the startup check immediately, so late and header-stripped color replies arrive after Pi thinks setup is done. Pull request 11642 filters those late replies out. Because some of this is…
Related on Windows: updates no longer fail when cleanup hits a locked file. If another Pi session holds open a native module, the cleanup step warned and aborted, leaving dependencies mismatched. Now, per pull request 11648, Pi warns, still installs dependencies for the new commit, and retries cleanup next time.…
Second, validation without code generation. Commit fab2c53 adds Pi Schema, which compiles JSON Schema once into plain functions with no eval, so it runs under strict content security policy. It passes all but one of over twenty-two hundred official suite tests, stays within twenty percent of the just-in-time leader…
Finally, Chord version 2 slice 10…
