This release includes breaking changes. Review the notes before updating production or shared instances.

Memos 0.30 delivers a major writing and navigation refresh centered on a rebuilt Markdown editor, richer memo details, configurable multi-column feeds, and faster feed rendering. It also replaces the MCP integration with an OpenAPI-driven tool surface, expands deployment-time configuration, and strengthens authentication, sharing, and private-instance access boundaries.

Breaking Changes

  • Private mode by default - Instances without --instance-url or MEMOS_INSTANCE_URL now run in private mode. Anonymous visitors are redirected to sign-in, anonymous API access is limited to setup, authentication, and shared-memo routes, and RSS feeds are unavailable. Set the instance URL to retain the previous public behavior.
  • Shared memo API - GetMemoByShare and GET /api/v1/shares/{shareId} have been replaced by GetSharedMemo and GET /api/v1/shares/{shareToken}/memo. Share-token responses are now limited to the shared memo, attachments, and reactions; parent memos, comments, and relations are no longer exposed through the token.
  • CEL timestamp filters - The now() function has been replaced by the now timestamp variable, and time fields now use CEL timestamps. Update saved shortcuts to use expressions such as created_ts >= now - duration("24h").
  • New MCP endpoint and tool names - MCP is now a stateless, tools-only endpoint generated from the OpenAPI schema. Clients must use /mcp and the new service-prefixed tool names. The previous prompts, resources, tool-filtering headers, route aliases, and unprefixed tool names have been removed.

New Features

Markdown Editing

  • Decorated-source editor - The editor has been rebuilt with CodeMirror 6, preserving Markdown verbatim while styling headings, formatting, tags, and mentions in place.
  • Formatting toolbar - A toggleable toolbar provides controls for headings, lists, task lists, code blocks, bold, italic, strikethrough, and inline code.
  • Smarter authoring - Tag completion, list indentation, improved keyboard shortcuts, and focus mode make it faster to write and organize memos.
  • GFM footnotes - Markdown rendering now supports GitHub Flavored Markdown footnotes with footnote navigation.

Memo Details and Feeds

  • Redesigned detail sidebar - Memo details now use a property rail with quick actions, editable visibility, metadata, attachments, relations, and a scroll-aware outline.
  • Flexible columns - Memo feeds support one, two, three, or automatically fitted columns, with balanced layouts as cards resize.
  • Persisted display preferences - Column count, compact mode, and link preview settings are saved between visits.
  • Restored feed position - Returning to a feed after viewing another page restores the previous scroll position.

MCP and API Tools

  • OpenAPI-driven MCP server - The hand-written MCP implementation has been replaced by a curated tool surface generated from the public API schema.
  • Expanded operations - MCP tools cover memos, comments, relations, reactions, shortcuts, identities, and attachments, including attachment uploads.
  • Canonical resource names - Canonical and nested resource names can be passed directly to follow-up tools.

Webhooks and Deployment

  • Signed webhooks - Standard Webhooks HMAC-SHA256 secrets can be generated, revealed, and used to verify webhook payloads.
  • Webhook management - Existing webhooks can be edited, and the interface shows whether signing is configured.
  • File-backed settings - Identity providers and supported instance settings can be supplied as validated JSON files under /etc/secrets.
  • Protected runtime overrides - File-backed settings cannot be changed through the UI or API until their files are removed.
  • Self-signed S3 support - S3-compatible storage can use insecureSkipTlsVerify when connecting with self-signed certificates.

Filters, Tags, and Settings

  • More powerful CEL shortcuts - Filters now support string matching, regular expressions, collection predicates, timestamp accessors, set operations, and an untagged-memos example.
  • Per-user tag settings - Tag colors and content-blur rules are now user-specific. Existing instance tag settings are copied to current users during migration.
  • Refreshed settings - Settings navigation and the access-token page now provide clearer guidance, safety notes, and last-used timestamps.
  • Searchable locale picker - The locale selector is easier to navigate, European locale coverage has expanded, and missing Japanese and Simplified Chinese translations are complete.

Improvements and Bug Fixes

  • Authentication and SSO - First-time SSO provisioning is now atomic across supported databases, valid external identifiers can become local usernames, and concurrent sign-ins no longer leave orphaned users.
  • Private-instance boundaries - Access policy is consistently enforced across Connect, REST Gateway, files, RSS, and share-token routes.
  • MCP reliability - Tool schemas, nested resource routing, error results, destructive-operation annotations, and oversized request handling have been hardened.
  • API compatibility - New resource IDs and annotations follow AIP conventions while remaining compatible with legacy UUID identifiers, and user-stat resources now return canonical names.
  • Comments and tasks - Memo details load every page of comments, expanded task-list state is preserved, and comment webhooks include the parent memo relation.
  • Tag parsing - Tags inside links are ignored, literal tags can be escaped with a backslash, and tag names support Unicode combining marks.
  • Interface polish - Loading feedback, mobile control spacing, long location labels, radio-group alignment, and tooltip positioning are improved.
  • Container startup - The container entrypoint no longer restarts indefinitely when MEMOS_UID=0.

Performance Improvements

  • Faster feeds and Explore - Fingerprinted assets are cached more effectively, media and rich renderers are deferred until needed, and feed content near the viewport is prioritized.
  • Shared data lookups - User and memo lookups are reused across creators, reactions, comments, mentions, and relations to reduce duplicate requests.
