-## Unreleased
+## 2.7.1
+Bugfix release. Added small optimizations to emoji picker that should make it a bit more responsive, however it needs rather large change to make it more performant which might come in a major release.
+
 ### Fixed
-- AdminFE button no longer scrolls page to top when clicked
+- Instance default theme not respected
+- Nested panel header having wrong sticky position if navbar height != panel header height
+- Toggled buttons having bad contrast (when using v2 theme)
+
+### Changed
+- Simplify the OAuth client_name to 'PleromaFE'
+- Small optimizations to emoji picker
+
+
+## 2.7.0
+
+### Known issues
+We got some reports related to emoji picker performance, this hopefully will be fixed in 2.7.1.
+
+### Notes
+This release overhauls how themes work, themes now need to be "compiled", which can cause some delay when loading for the first time and temporarily look "wrong" in some places (popups, menus, dialogs). Please do report any issues, especially if your theme looks wrong or breaks interface when loading. Also report issues if you're experiencing constant performance issues.
+
+To admins: remember that you can update PleromaFE to recent `master` or `develop` in admin dashboard in "Front-ends" tab, scroll down to find PleromaFE box and click "Reinstall `master`" or dropdown and then "Reinstall `develop`". Currently there is no mechanism to check if there is an update or not.
+
+### Changed
+- Overhauled the way themes work, migrating to new Pleroma Interface Style Sheets system aka "Themes 3".
+- Notifications are no longer sorted by "seen" status since interacting with them can change their read status and makes UI jumpy. Old behavior can be restored in settings.
+- Notifications are now shown through a ServiceWorker (since mobile chrome does not allow them otherwise), it's always enabled, even if previously we only enabled it for WebPush notifications only. If you don't like websites "running" while closed, check how to disable them in your browser. Old way to show notifications will be used as a fallback but might not have all the new features.
+- Reorganized Settings modal to move out visual stuff into Appearance tab
+
+### Added
+- Emoji pack management to the admin panel
+- Support `status` notification type (subscriptions/bell, fixes PleromaFE on newer PleromaBE versions)
+- Poll end notifications.
+- Added option to not mark all notifications when closing notifications drawer on mobile, this creates a new button to mark all as seen.
+- Option to always "show" notifications when using web push for better compatibility with some browsers (chrome, edge, safari)
+- Option to toggle what notification types appear in native notifications, by default less important ones (likes, repeats, etc) will no longer show up in native notifications.
+- Option to treat non-interactive notifications (likes, repeats et all) as seen for visual purposes (no read mark, ignored in counters, still can show in native notifications)
+- Ability to resize UI (and certain components) scale independent of browser/text scale
+- Ability to override certain aspects of UI style independent of theme used (UI roundness, fonts, underlay)
+- Theme selector with visual previews of the theme
+- Display loading and error indicator for conversation page
+- Option to only show scrobbles that are recent enough
+- Interacting (opening reply box etc) or simply clicking on non-interactive notifications now marks them as read. Clicking on native notifications for non-interactive ones also marks them as seen.
+- Support group actors
+- Focusing into a tab clears all current desktop notifications
+- Ability to change size of emoji
+- Ability to view APNG (Animated PNG) attachments.
+- Support showing extra notifications in the notifications column
+- Create a link to the URL of the scrobble when it's present
+- Allow hiding custom emojis in picker.
+- Ability to mute sensitive posts (ported from eintei).
+- Native notifications now also have "badge" property that matches instance's favicon (visible in Android Chromium at least)
+- Display public favorites on user profiles
+- Display quotes count on posts and add quotes list page
+- Show a dedicated registration notice page when further action is required after registering
+
+### Fixed
+- Synchronized requested notification types with backend, hopefully should fix missing notifications for polls and follow requests
+- Error that appeared on mobile Chromium (and derivatives) when native notifications are allowed
+- Being unable to set notification visibility for reports and follow requests
+- Native notifications appearing as many times as there are open tabs. Clicking on notification will focus last focused tab.
+- The expiry date indication won't be shown if the poll never expires
+- Profile mentions causing a 422 error on newer PleromaBE versions.
+- Color inputs are less ugly now
+- Unread notifications should now properly catch up between sessions (eventually) in polling mode
+- Video posters on Safari
+
+
+## 2.6.1
+### Fixed
+- fix admin dashboard not having any feedback on frontend installation
+- Fix frontend admin tab crashing when no primary frontend is set
+- Add aria attributes to react and extra buttons
+
+## 2.6.0
+### Added
+- add the initial i18n translation file for Taiwanese (Hokkien), and modify some related files.
+- Implemented a very basic instance administration screen
+- Implement quoting
+
+### Fixed
+- Keep aspect ratio of custom emoji reaction in notification
+- Fix openSettingsModalTab so that it correctly opens Settings modal instead of Admin modal
+- Add alt text to emoji picker buttons
+- Use export-subst gitattribute to allow tarball builds
+- fix reports now showing reason/content
+- Fix HTML attribute parsing, discard attributes not strating with a letter
+- Make MentionsLine aware of line breaking by non-br elements
+- Fix a bug where mentioning a user twice will not fill the mention into the textarea
+- Fix parsing non-ascii tags
+- Fix OAuth2 token lingering after revocation
+- fix regex issue in HTML parser/renderer
+- don't display quoted status twice
+- fix typo in code that prevented cards from showing at all
+- Fix react button not working if reaction accounts are not loaded
+- Fix react button misalignment on safari ios
+- Fix pinned statuses gone when reloading user timeline
+- Fix scrolling emoji selector in modal in safari ios
+
+## 2.5.1

+- Optional confirmation dialogs when performing various actions
+- You can now set fallback languages
+
+## 2.5.0 - 23.12.2022

+- Notifications about likes/repeats/emoji reacts are now minimized so they always take up same amount of space irrelevant to size of post. (You can expand them to full if need be)

 # For Translators
 
-To translate Pleroma-FE, add your language to [src/i18n/messages.js](https://git.pleroma.social/pleroma/pleroma-fe/blob/develop/src/i18n/messages.js). Pleroma-FE will set your language by your browser locale, but you can temporarily force it in the code by changing the locale in main.js.
+To translate Pleroma-FE, use our weblate server: https://translate.pleroma.social/. If you need to add your language it should be added as a json file in [src/i18n/](https://git.pleroma.social/pleroma/pleroma-fe/blob/develop/src/i18n/) folder and added in a list within [src/i18n/languages.js](https://git.pleroma.social/pleroma/pleroma-fe/blob/develop/src/i18n/languages.js). 
 
-# FOR ADMINS
+Pleroma-FE will set your language by your browser locale, but you can change language in settings.
 
-You don't need to build Pleroma-FE yourself. Those using the Pleroma backend will be able to use it out of the box.
+# For instance admins
+You don't need to build Pleroma-FE yourself. Those using the Pleroma backend will be able to use it out of the box. Information of customizing PleromaFE settings/defaults is in our [guide](https://docs-develop.pleroma.social/frontend/CONFIGURATION/) and in case you want to build your own custom version there's [another](https://docs-develop.pleroma.social/frontend/HACKING/)
