Gemini CLI updates auto routing for 3.5 flash and adds Antigravity CLI migration docs
Gemini CLI's June 2026 releases focused on model routing, Antigravity CLI migration and terminal stability. Seven releases shipped, from v0.45.0 to v0.49.0, and the release notes are mostly raw pull request lists, so only the clearer changes are summarized here.
On models, v0.45.0 updated the default auto routing, v0.46.0 added a transition to the flash GA model when an experiment flag is present, and v0.47.0 changed auto mode to use 3.5 flash when the flag is enabled. v0.47.0 also added documentation and migration commands for Antigravity CLI and raised the cap on how often the Antigravity transition banner can show. Reliability work included hardening PTY resize against native crashes, an atomic update in MCP tool discovery, fail-fast handling of zero-quota limits to avoid a retry-loop hang, and a path traversal fix during skill install. v0.45.1 to v0.45.3 were patch cherry-picks.

- Default auto routing updated, and a transition to the flash GA model when an experiment flag is present (v0.45.0, v0.46.0)
- Zero-quota limits now fail fast instead of hanging in a retry loop (v0.49.0)
- Path traversal vulnerabilities prevented during skill install (v0.49.0)
- PTY resize hardened against native crashes; MCP tool discovery now updates atomically (v0.46.0, v0.47.0)
