Gemini CLI v0.57.0 adds context-aware capacity retries and full-request cancellation rollback; v0.59.0-nightly hardens MCP SSRF
Google DeepMind
v0.57.0 (Aug 25) dynamically resolves Cloud Workstations proxy redirect URIs for OAuth, implements context-aware silent retries with availability TTL for capacity errors, rolls back the entire multi-turn request on cancellation/abort, preserves empty text turns with tools/media, and adds a tool-call formatter and failure summaries for evals. Nightly v0.59.0-nightly.20260827 (Aug 27) adds SSRF prevention in MCP OAuth metadata discovery and authentication. v0.58.0-preview.0 (Aug 25) cleans up symlink handling and macOS Seatbelt container/runtime socket isolation.
Why it matters
The MCP SSRF hardening is a meaningful security uplift on a security-sensitive code path; the cancellation rollback behaviour prevents partial-state corruption when a multi-turn request is aborted.
