+
+*October 2026 · Basic Memory Cloud is rolling out 1.0 now. The core package's 1.0 changes are on `main` and not yet in a published release: see the [Unreleased section of the changelog](https://github.com/basicmachines-co/basic-memory/blob/main/CHANGELOG.md#unreleased).*
+
+In Basic Memory Cloud, every project opens as a [Wiki](/cloud/wiki), with an overview, folder pages, and a change log kept current as `index.md` and `log.md` files in the Open Knowledge Format. Notes can hold [live notes](/cloud/live-notes) components (KPIs, Gantt charts, comparisons, task boards) written in Comark, including live views that query the project each time you open them. Uploaded PDF, Word, PowerPoint, and CSV files become searchable notes. [Basic Memory agents](/agents/about) (beta) look after notes on their own, with every change in a shared review queue you can keep or undo. In browsers that support WebMCP, the web app gives browser agents tools that act as you. Plans move to Cloud ($19), Pro ($99), and Business ($250), with usage credits, member limits, and a spending limit you set; see [Plans and Billing](/teams/seats-and-billing) and [Usage and Credits](/cloud/usage-and-credits).
+
+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.
