Antigravity 2.21.1, CLI 1.3.1 Ship

This is a maturity-focused update: Antigravity is tightening the workflow around long-running, multi-agent development rather than chasing another flashy feature.

• –Advanced Search and Automations make the desktop app more useful as a persistent agent workspace.
• –Grouped edits, commands, and file reads improve reviewability, though collapsing activity can still hide important execution detail.
• –Native Android/Termux support expands where developers can run the CLI, while improved diff navigation makes terminal review less painful.
• –The rapid release cadence signals strong momentum but also creates upgrade churn for teams that need stability.
• –Product Hunt users praise planning and parallel agents while still flagging usage limits, weaker fallback models, and multi-file reliability concerns. [Community feedback](https://www.producthunt.com/products/google-antigravity)
