Highlights

Section titled “Highlights”
  • Antigravity Agent & PR Generator: Integrated the Antigravity agent runner, Firestore dual-locking for concurrency, prompt templates, and ingestion testing utilities.
  • Caretaker Triage & Issue Management: Enhanced the issue triage workflow by automatically posting a comment before closing issues, and sanitizing and wrapping issue titles in untrusted_context.
  • Core API & Session Stability: Enforced HTTPS for GoogleCredentialsAuthProvider to prevent cleartext leakage, rotated session IDs on model fallback to prevent stateful API errors, and refined chat history by filtering out thought parts when context management is disabled.
