> What changed in the platform and in this documentation, by date.

## 2026-09-23

- **Switch engines**: `PATCH /api/v2/agents/:id` accepts `engine` (optional `model`). The agent keeps its identity, skills, knowledge, channels and permissions; conversation memory stays with the previous engine.
- A new machine for an agent (after it is recycled) now starts with the skills and files you uploaded; before, it only got the identity.
- **Google Drive connector**: the agent reads the sheets, docs and CSVs you pick in Google's picker, and can append rows or update cells. It only sees what you pick. See [Connectors](/en/docs/connectors).

## 2026-09-21

- **Overridable system prompt**: `PATCH /api/v2/agents/:id` takes `promptMode` (`append` | `replace`); with `replace` the agent is only your identity, without the Ghosty persona. The house persona now answers in the language it is written to (it used to force Spanish).

## 2026-09-16

- **Docs for agents**: every page exists as markdown at `<url>.md`; "Copy markdown", "Open in Claude / ChatGPT" buttons and the MCP block; [documentation MCP server](/en/docs/protocols/docs-mcp) at `/mcp/docs` (`search_docs`, `read_doc`, `list_docs`, `openapi`); copyable prompts per guide; curl/TypeScript/Python tabs; "Try it" in the reference with your token.
- **Agent creator v2**: Describe / Template / Blank, eight house [recipes](/en/docs/getting-started/recipes), upload or download an agent's `.yaml` recipe.
- **Agent configuration API** (`/api/v2/agents/:id`): identity, model, files, skills and MCP servers with the agent's token. `ghosty-agent` skill for Claude Code/Cursor/Codex: `npx skills add https://ghosty.studio`. Guide: [Configure your agent](/en/docs/configure).
- The web chat now delivers PDFs and documents to the agent (it used to fail with "could not deliver").
- **WhatsApp per agent**: on the agent card turn on the channel and tick which numbers (connected from Sales) it answers.
- **Hand over an agent** to another account with its configuration, memory and files (card → Avanzado).
- What the agent delivers (documents, images) is saved in your account files and shown on the web.
- Archived conversations no longer show in the list.
- This documentation is born: getting started, concepts, channels, connectors, protocols (ACP, A2A, MCP), API with OpenAPI 3.1, events, errors.
- `/docs/acp` moves to [/docs/protocolos/acp](/en/docs/protocols/acp) (redirects).
- `/openapi.yaml` and `/llms.txt` available.

## 2026-09-14

- **Correct mid-turn**: writing to the agent while it works enters the running turn instead of waiting for it to finish (Teams and API).
- The stream batches tokens on mobile so as not to saturate the UI.

## 2026-09-11

- **Scheduled turns**: the agent can work for days without anyone connected (`POST …/schedule`).

## 2026-09-09

- Connectors in the mobile app: EasyBits as the first live connector.

## 2026-09-02

- An ACP agent comes back up on its own if its machine disappeared: transparent `revive` before the first message.

## 2026-08-27

- Attachments are delivered as **access** to the file: the agent reads it with its tools instead of receiving an inline copy.

## 2026-08-26

- `ghosty-acp` published on npm (MIT, zero dependencies).
