What is done, what is next, and what was left out on purpose.
- Complete rewrite for PHP 8.2+ (the old code stopped working with PHP 7)
- InnoDB schema with foreign keys, utf8mb4 and full text indexes
- Questions, answers, comments, votes, accepted answers, favourites
- Tags with wikis and synonyms, revision history with diffs
- Karma with a daily cap, configurable thresholds and a full audit trail
- 32 badges, awarded inline and by a background job
- Flags, community close votes, suspensions, moderator queue
- Markdown editor with preview, image upload, drafts in local storage
- Full text search with operators and search suggestions
- Argon2id passwords, email verification, password reset, TOTP 2FA, OAuth2
- Notifications, subscriptions, private messages, mail queue and digests
- JSON API for everything, with API keys and rate limits
- Admin area: settings, users, moderation, statistics, health
- German and English UI, RSS, sitemap, OpenSearch, schema.org markup
- Docker Compose stack, background job runner, CI, tests, smoke tests
- Importer for the 2013 database
Content
- Bounties end to end (the schema and the expiry job exist, the UI does not)
- Merge duplicate questions instead of only linking them
- Draft questions and scheduled publishing
- Code syntax highlighting (highlight.js as an optional include)
- Optional LaTeX rendering for maths heavy communities
Community
- Review queues in the style of "first posts" and "late answers"
- Trusted user privileges (edit without review, retag)
- Weekly "top contributors" mail
- User blocking and per-tag muting
Search
- Optional Meilisearch or Typesense backend for larger installations
- "Related questions" from a proper similarity score instead of MATCH
- Saved searches with mail alerts
Platform
- Translation coverage: 397 of 501 UI strings are translated to German
- More languages, ideally through a translation platform
- Webhooks for new questions and answers
- Single sign on via OIDC for company installations
- Import and export in the Stack Exchange data dump format
- Progressive web app with push notifications
- Accessibility pass with a screen reader
Operations
- Structured logging with a request id
- Prometheus metrics endpoint
- Backup and restore command
- Optional Redis session and cache backend
- A framework. The point of this project is that it runs anywhere with a copy of the files.
- A build step for the frontend. Vue islands from a CDN keep deployment to "upload the files".
- A plugin system with hooks everywhere. Skins and the API cover the realistic extension points; a hook system would age badly.
- Comment threading. Comments are for clarification, answers are for answers.
