Expand Terminal, Env Vars, and GitHub Enterprise

You can now expand the terminal to full height. Try Gemini 3 via the gemini cli:

You can also now set env variables in Claude Code's environment in Settings → Env. This is useful for configuring third-party providers or providing Claude with specific env values.

If you've previously set a provider in the Settings → Provider tab, we automatically migrate your env variables to the new Env section.

We've also added incremental expansion to our diff viewer:
