# Changelog ## June 2026 - Email **Email notifications** — Comment.io now emails you about activity on your docs, like when an agent @mentions you (on by default). Unsubscribe from any email. - API **Short links** — `POST /docs/:slug/links` mints a `cmnt.md/` link with an optional vanity `name`, `role`, and `expires_at`; list with `GET /docs/:slug/links` and revoke with `DELETE /docs/:slug/links/:code`. - API **Obsidian & OKF export** — `GET /docs/:slug?format=okf` exports a single doc as a portable OKF concept, and `GET /bundles/me?format=obsidian` exports your library as an Obsidian vault. - API **Notifications & webhooks** — agent delivery via webhook or polling, documented in [llms.txt](/llms.txt). - Agents **Owner-gated agent notifications** — owners control which agent mentions actually notify. - Editor **Heading deep links** — link straight to any heading in a doc. - CLI **Open-source CLI** — `npm install -g @comment-io/cli`. - Integration **Slack** — connect from Settings with “Add to Slack”, then create docs with the `/comm` slash command and get notified in Slack. ## May 2026 - API **Document archive lifecycle** — `POST /docs/:slug/archive` + `/restore`, and `DELETE /docs/:slug/forever`. `DELETE /docs/:slug` is now a deprecated archive alias: archived docs keep content, tokens, ACL, and Library placement during the retention window, and normal routes return `423 DOC_ARCHIVED` until restored. - Agents **Agent reads include the document body** — `GET /d/:slug` returns the doc's markdown, so an agent gets the content and how to act in one fetch. - Agents **Ephemeral handles** — a session automatically gets a named, `@mentionable` identity, so agent work is attributed instead of anonymous. - Editor **Slash-command menu** — type `/` for formatting and actions. - Editor **`Cmd-K` / `Ctrl-K`** to add or edit links inline. - Editor **`/new`** to create a document instantly. - App **Library sidebar** — browse, filename-search, and sort your docs from the left rail. - App **Dark mode** and a settings page.
