v0.30.0-rc.1

A rebuilt Markdown editor, OpenAPI-driven MCP tools, flexible memo feeds, and signed webhooks

July 14, 2026
View tagged release

This release candidate rebuilds the Markdown editing experience, introduces a stateless OpenAPI-driven MCP server, and adds flexible memo feed layouts, signed webhooks, file-backed deployment settings, and more powerful filters. It also includes breaking changes to public access, CEL time filters, and MCP clients.

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, and anonymous API access is limited to setup, authentication, and shared-memo routes. Set the instance URL to retain the previous public behavior.
  • CEL timestamp filters - The now() function has been replaced by the now timestamp variable, and time fields now use CEL timestamps.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") or timestamp(<epoch>) instead of comparing time fields with bare epoch values.
  • New MCP endpoint and tool names - The MCP server 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 and list indentation make it faster to write and organize memos.
  • GFM footnotes - Markdown rendering now supports GitHub Flavored Markdown footnotes with footnote navigation.

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  • OpenAPI-driven MCP server - The hand-written MCP implementation has been replaced by a curated tool surface generated from the public API schema.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.
  • Shared authorization - MCP reuses the public API's authentication and authorization behavior for more consistent access control.

Memo Feed Customization

  • 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.
  • Predictable memo placement - Newly created memos remain easy to find above pinned content.
  • Full content by default - Compact rendering is now opt-in for single-column feeds.

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 the insecure_skip_tls_verify option when connecting with self-signed certificates.

Filters, Tags, and Localization

  • 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.
  • 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 Security

  • More reliable SSO setup - SSO option loading is more stable, and OAuth client authentication can be detected automatically.
  • Clearer instance setup state - Setup now distinguishes new instances from populated instances that no longer have an administrator.
  • Cross-origin bearer authentication - Cross-origin API requests work with bearer tokens while cookie authentication remains restricted to same-origin requests.
  • Consistent user pagination - ListUsers now returns predictable paginated results.

Editor and Memo Reliability

  • Editor polish - Formatting toggles, keyboard shortcuts, file paste and drop handling, focus-mode layout, empty-space caret behavior, and CodeMirror spacing are improved.
  • Persistent task expansion - Expanded task-list state is preserved.
  • Complete comment loading - Memo detail views load every page of comments.
  • Richer webhook payloads - Comment webhook events include the parent memo relation.

Tags and Interface

  • More accurate tag parsing - Tags inside links are ignored, literal tags can be escaped with a backslash, and tag names support Unicode combining marks.
  • Refreshed account pages - Sign-in, sign-up, and About pages have updated layouts, with common controls aligned across the app.
  • Improved loading feedback - Mismatched memo skeletons have been replaced by a delayed spinner.
  • Mobile and location polish - Mobile control spacing is improved, and long location labels are truncated without hiding the full address.
  • Container startup fix - The container entrypoint no longer restarts indefinitely when MEMOS_UID=0.
