Google Gemini CLI released a v0.61.0-preview.0 with fixes for Flash model IDs and security hardening, alongside a v0.60.0 stable release focused on security improvements.

READY TO POST:

gemini-cli just dropped v0.61.0-preview.0 with a fix for flash model ids and some pretty significant security hardening. worth a look if you're building with it!

a new gemini-cli v0.60.0 stable release is out, focused on a bunch of security fixes and boundary validations. always good to see those updates.
