Release note — v2.7.1

ThatCode v2.7.1 — first ThatCode Windows release after the Muse pivot.

Repo agent on your machine. Bring your own API.

Highlights

• Single coding agent with sandboxed tools, change review, and verify loop
• RAG + @ context — @codebase, @file, @folder, @symbol, project rules
• Agent tiers (auto / quick / standard / deep / explain), plan-before-edit, streaming replies
• Reliability fixes — final message delivery, tool activity UX, parse fallbacks, Windows npm.cmd support

Upgrading from Muse 2.x: clean install (com.thatcode.app is a new app id).

Muse v2.1.0

Muse v2.1.0 extends the companion with new personalities and memory, and gives the executor git workflow, MCP, and smarter task handling — while staying local-first and companion-first.

---

Highlights

Personalities

Choose how Muse feels in conversation. Luna, Sage, and Spark share the same executor but bring different tone and localized greetings. Switch in Settings anytime.

Long-term memory

Save facts and preferences in SQLite from Settings. Memories are injected into companion chat and delegated tasks so Luna (or Sage/Spark) can remember what matters to you across sessions.

Git workflow tools

The executor can git_add, git_commit, and git_checkout_branch inside your sandboxed workspace — useful for small, guided repo changes without leaving the chat.

Task queue

When enabled in Settings, delegated tasks run sequentially instead of overlapping — better for multi-step coding or planning sessions.

Auto-index RAG

Turn on the workspace file watcher to re-index RAG automatically when files change. Keeps retrieval in sync with your project.

MCP client (minimal)

Connect a stdio MCP server from Settings. Muse merges extra mcp_* tools into the executor loop for lightweight extensibility.

Command allowlist

Extend which shell command prefixes the executor may run — editable in Settings for your local workflow.

• From v1.x: See CHANGELOG.md for v1.5 and v2.0 changes (workspace tools, verify loop, change review, structured tools, context pack).
