MB 2.1.0

Install or upgrade with brew install jthingelstad/tap/mb (or brew upgrade mb).

• Versioned results. Every CLI --format json envelope and MCP result starts with "schema_version": 1. Adding a field keeps the version; removing, renaming or retyping one bumps it.
• Per-tool output schemas. Each of the 23 MCP tools publishes the schema of its own result instead of one generic envelope, and docs/mcp-schemas.json collects them. Tests validate real stdio results against them.
• Compact MCP reads. Read tools return content_text, a flat author, and links and images lists, without the HTML, the upstream author and _microblog blocks, feed metadata or the repeated identity. Own-blog lists return a 500-character excerpt. Live, a typical session's results are about a third of their 2.0 size. Pass verbose: true for the full shape. profile_get adds a flat profile, and blog_posts now reports returned_count. CLI JSON is unchanged apart from schema_version.
• Inbox rebaseline. When the saved mention has aged out of Micro.blog's recent mentions window, inbox reports anchor_missing: true and still offers no acknowledgement. After the person agrees, inbox with rebaseline: true lets the recent window be acknowledged, and checkpoint_ack reports rebaselined with the previous_checkpoint.
• Heartbeat pages. The first heartbeat stays a 3-post snapshot; later heartbeats page 20 posts at a time since the checkpoint. count still overrides.
• State file name. The shared receipt and checkpoint store is now ~/.config/mb/state.sqlite3. An existing 2.0 mcp-state.sqlite3 keeps being used while it is the only one, so no receipts or checkpoints are lost; nothing is moved or renamed automatically.
• Install name. The Homebrew tap is now jthingelstad/tap: brew install jthingelstad/tap/mb.
