 In the core package, the MCP server moves to the 1.0 `bm_*` tools: twelve tools such as `bm_read`, `bm_write`, `bm_edit`, `bm_search`, and `bm_context`, plus an opt-in `bm_project_delete`, with typed refusals and a manual page for each. `bm doctor` becomes a read-only report on your real projects, with the command that fixes each problem, and a `memory-doctor` skill walks an agent through it. Fixes cover watching newly created projects, large vector deletions and interrupted migrations on SQLite, and a stale storage read that could roll a note back to an older version. FastAPI is upgraded past the v0.24.1 pin.
 
-Breaking changes: the MCP tools are renamed and their arguments change, and with several projects, note and search tools need an explicit project. Read [Basic Memory 1.0](/whats-new/basic-memory-1-0) for the highlights and [Migrating to 1.0](/reference/migrating-to-1-0) before switching clients.
