# Gemini CLI v0.57.0-preview.0: OAuth proxy fix, capacity-retry TTL, multi-turn rollback, TUI hang timeout

> Preview release with notable infrastructure fixes: Cloud Workstations OAuth proxy redirect now resolves dynamically, capacity errors use context-aware silent retries with a TTL, cancelled multi-turn requests roll back fully, the TUI no longer hangs indefinitely (execution timeout added), and a directory mismatch in IDE connections is fixed. Also includes evaluation tooling (tool call formatter, failure summaries) and many SSR-agent issues (privacy notice wording, /clear context reset docs, fixed admin error for personal accounts, strict-null errors in tests, subagent output formatted as markdown).
