🐦⬛ Mastodon Bird UI 5.0.0-beta.1-2026-11-08 (nightly) is out. This is Bird UI rebuilt for Mastodon 5, the new 5.0 design that is now in beta.
The nightly follows Mastodon 5.0.0-beta.1. If you are on Mastodon 4, stay on 4.7.3-2026-10-11 from the main branch.
New:
- Rewritten from scratch for the Mastodon 5 design
- Micro-interactions, likes and boosts are whimsical
- Notifications, content warnings, link cards and thread lines look like they did on Mastodon 4
- Follows Mastodon's own light, dark and high contrast settings
- A darker, blurred backdrop behind the composer and every popup
- A new install script for Mastodon 5, or paste dist/mastodon-bird-ui.css into Custom CSS
- The star favorite, light and language variants are no longer supported

Release notes and full changelog: https://github.com/rollecode/mastodon-bird-ui/releases/tag/5.0.0-beta.1-2026-11-08
Lots of nightly updates coming in today!
Most notable bugs:
- When you type a hashtag or at-person, the popout gets in the way
- Ultra Accessible themes for vision impaired have some font size issues
- Some hover states and element proportions, especially padding, have regressions from v5 and the new nightly theme
- Bugs in the advanced view
The latest changes are in the nightly branch, and work is still in progress. You can follow my work here: https://github.com/rollecode/mastodon-bird-ui/tree/nightly
Some of these are core issues and will probably be fixed or changed in Mastodon v5 stable. If not, fixes will go live in our fork.

Small personal plug: people keep asking what to use now that EchoFeed is winding down, so here is what I use. I built it, so take that with whatever grain of salt you like.
FeedEcho watches your RSS, Atom, or JSON feeds and posts new items wherever you want them:
- Mastodon (one-click OAuth), Bluesky, micro.blog, Matrix, Discord, Telegram, email, generic webhooks
- Jinja2 templates for the post format, with a live preview
- Field-scoped filters (tag:, author:, url:, content:) and per-echo content warnings
- Drip mode, auto-queue, or review-first drafts if you don't want it posting unsupervised
- Image attachments with optional AI alt text, duplicate protection, retries with backoff
- Built-in feed reader with folders, OPML import/export, saved searches, and a compose desk
- Self-host with Docker or use the hosted one
Happy to answer questions if anyone is setting it up.
