The major feature in v3.2.0 of Ktistec is thread analysis. The previous release, v3.1.2, added support for viewing threads from Lemmy communities. I follow the Open Source community, which leads to many large threads. The thread on FFMpeg and Google has 112 posts and is still growing.

Thread analysis helps me navigate these extensive conversations. It includes: top contributors, a timeline histogram, and notable branches.

The analysis applies several heuristics to identify interesting branches of the main thread. “Interesting” is subjective, but the algorithm currently looks for sudden bursts of activity and highlights those areas. Ktistec uses this to create a table of contents that links directly to those branches. Clicking on one of these links takes you to a branch-only view that focuses on the selected part of the thread.

It's fast—I anticipated needing to cache analyses, but analyzing a thread with over 400 posts takes only about 50 milliseconds on my production server.

This release also addresses an object visibility regression that was introduced in a previous version.

Full Changelog

Added

• Thread analysis that displays key participants, a timeline histogram, and notable branches
• New MCP tools: analyze_thread and get_thread
• Focal point rendering support for image attachments

Fixed

• Regression in object visibility affecting replies to threads

Changed

• Enhanced MCP tool details for likes, dislikes, and announces
• Improved cookie security.

There are two big features in release v3.1.3 of Ktistec: auto-approve followers and a new image viewer.

Auto-approve followers is conceptually simple ("the server automatically sends an Accept activity when it receives a Follow activity") but it required extensive changes to some of the oldest code in the codebase: the inboxes and outboxes controllers. I refactored inbox and outbox side-effect processing into independent services, which made it possible to support side-effects like auto-approve follow (and also auto-follow back), without having to go through the controllers.

A more significant change for me personally was replacing the lightGallery image gallery (an external dependency) with my own implementation. It's not as slick, and not as full of features—I wrote it in two days—but it is fully free software, and that's important to me.

Added

• Add admin page for managing OAuth access tokens.
• Add support for auto-approve followers. (fixes #26)
• Add support for auto-follow back.

Fixed

• Prevent triggering actor refresh when user is anonymous.

Changed

• Replace "lightgallery" dependency with custom image viewer.
• Set OAuth access token expiry to 30 days (previously expired after 24 hours).
• Refactor inbox and outbox processing into dedicated processor services.

The OAuth changes set the groundwork for better support of the Mastodon API and the Fediverse clients that depend on it. Stay tuned!

I'm working on federation issues.

👻 Release v3.1.2 of Ktistec improves support for Lemmy and community servers like it that distribute content by wrapping it in Announce activities (FEP-1b12: Group federation support). Ktistec also supports the audience property, although support for that was removed from Lemmy earlier this year.

🎃 This release also adds support for delivering to shared inboxes, which are widely supported by other ActivityPub servers. Despite being federated, the Fediverse is not highly distributed, and this optimization can reduce outbound delivery traffic by 10-20x.

Added

• Support for the Dislike activity.
• Support for the audience property on activities and objects.
• Support for delivery to shared inboxes.
• Support for full-width hash signs in hashtags (e.g. ＃日本語) commonly used in Japanese and other Asian languages.

Fixed

• Strip HTML from object summaries rather than escaping it.
• Properly unwrap Lemmy-style Announce activities.

Changed

• Destroy discarded drafts instead of deleting them.

Enjoy!
