v0.2.280
Shared chat experience for every agent.
Pin a turn layout, collapse tool calls by default, set a chat accent — once. Every agent inherits the same UX (Claude, Codex, Antigravity, oMLX). Default turn layout is now nested cards.
Changelog

Coding agents — four real ones, one local
v0.2.280
Local oMLX sessions resume across launches.
Quit the app, relaunch, switch decks, swap models — your oMLX conversation continues with the model's working memory intact. Backed by a new per-feature omlx-sessions.sqlite.
v0.2.269
Run a fully-local coding agent.
A 5th agent harness landed: oMLX (local). Defaults to Qwen3.5-9B running on your Mac, with four sandboxed tools (list_dir, read_file, write_file, run_command) scoped to your workspace and an Approve / Deny / YOLO flow for destructive calls.
v0.2.264
Google Antigravity is a first-class agent.
Added support for Google's Antigravity (the Gemini coding harness) alongside Claude and Codex. The 96 MB harness binary auto-downloads on first use; YOLO mode skips per-tool confirmations once you've signed off on the workflow.
Performance
v0.2.279
79% faster long code streams. 92% lower worst-case latency on long conversations.
Document-chunked markdown rendering coalesces streaming text into stable chunks, so the renderer only re-parses the trailing few paragraphs per delta. Long Antigravity sessions feel real-time again.
v0.2.277
88% faster transcripts on long Gemini sessions.
A split-projection cache means settled turns are never re-projected; only the open turn re-runs through the renderer per event. Combined with a shared markdown block cache, the worst-case 1097-event session dropped from 53 ms to 6.5 ms per layout pass.
v0.2.263
Smaller, faster releases.
dsymutil + strip -x in the build pipeline shaved ~49 MB off the shipped binary. Crash-log symbolication is preserved via a sibling dSYM bundle. No behaviour change.
Privacy & quality of life
v0.2.275
Goodbye Keychain prompts.
API keys now live in a single 0600 JSON file under Application Support — same security posture as your shell's dotfiles, none of the "Allow Deckosaurus to access your keychain?" pop-ups. One-shot migration moves any existing keys across.
Multi-session UX
v0.2.266
Up to four parallel Antigravity sessions per deck.
Tab-strip UX mirrors Claude's: spin up multiple agent conversations per workspace, switch with the keyboard, each with its own persisted transcript on disk.
Polish
v0.2.255
Files reshape: tree in the deck sidebar, document tabs in the Files widget.
The file tree is now a top-level sidebar — always available regardless of which panel is active. Toggle it with Cmd+B. Read-only preview tabs sit alongside persistent editor tabs.
