Zed ships stable v1.20.1 and pre-release v1.21.0 with Grok sign-in and DeepSeek Flash 4.1
Zed Industries
Zed published stable v1.20.1 on Sep 16 with optional cursor movement animation, configurable window titles, Gemini 3.8 Flash support, and binaries roughly 25% smaller from stripped debug symbols. The v1.21.0 pre-release adds SuperGrok sign-in for Grok models in the Agent Panel, DeepSeek Flash 4.1 support, an agent.prevent_idle_sleep setting for long agent turns, and faster syntax-highlighted rendering.
Why it matters
Zed keeps widening its agent-panel model catalog (Grok, DeepSeek, Gemini), and the prevent_idle_sleep setting acknowledges multi-hour agent turns as a first-class editor workload.
