###### Highlights

- End-to-end encrypted mobile push notifications are now generally
  available and enabled if both server and client are modern.
- Uploaded images and audio files now use the `![alt text](url)` markdown
  syntax, which does not require a separate link element.
- Added a new organization setting for media preview size,
  controlling image and video thumbnail sizes in message content.
- Added support for using Jdenticons for default profile pictures.
  Jdenticons render better in both Zulip themes and have less
  privacy risk than Gravatar, and are the default for new
  organizations.
- Redesigned the Recent Conversations view with a new table layout,
  one-line conversation display, folder filter dropdown, improved
  column sizing and alignment, and better touchscreen support.
- Redesigned channel-specific settings, with a much cleaner view and a
  dedicated "Permissions" tab. The channel settings panel now supports
  filtering by folder.
- Emoji-only messages now render the emoji extra large.
- Linkifiers now support reverse linkification: pasting a URL
  matching a linkifier pattern auto-converts to its short text
  form.
- Added a jump-to-date picker in the message feed, accessible by
  clicking a date separator or the date in the conversation header bar.
- Added support for administrators to bulk-edit most settings for
  existing users via the "Default user settings" panel. Administrators
  can choose to only edit settings for users who haven't already
  changed that setting. (Security and privacy settings cannot be
  edited by administrators).
- Added Nextcloud Talk, Constructor Groups, and Webex as video call
  provider options.
- Added a "Report message" feature, with a configurable private channel
  for moderators to handle reports.
- Added demo organizations, which allow testing Zulip without
  sharing an email address.
- Improved search typeahead with topic suggestions from all subscribed
  channels and nicer styling for channel/topic pair suggestions.
- Added many new default external account types for custom profile
  fields, made the URL pattern optional, and made external accounts
  available for matching users in typeahead.
- Added a beta data import tool for Microsoft Teams.
- Migrated the help center to Starlight, the Astro-based static site
  generator, adding full-text search and a modernized design.
- The Zulip Docker container has been reworked, and the new version
  published as https://ghcr.io/zulip/zulip-server. This resolves nearly
  all outstanding issues in the issue tracker, and adds tests and
  substantially more documentation, for both Docker Compose and Helm
  deployments. See the [upgrade notes](#upgrade-notes-for-120) for details.
