The big feature in release v3.2.2 of Ktistec is pinned posts with support for the Mastodon Featured Posts collection. Federation works both ways—pin a post on Ktistec and it will show up as a pinned post on Mastodon and vice versa. When you refresh an actor profile, Ktistec also fetches and updates the actor's pinned posts. This is another small step in the direction of supporting all features that Mastodon-compatible client applications expect to access via the API. It's also useful in its own right.

The other major feature, which I posted a short video demonstrating here, is X-Ray Mode. X-Ray Mode is a developer and power-user tool for inspecting ActivityPub JSON-LD representations of actors, objects, and other content. Pressing Ctrl+Shift+X on any page displays the data behind the page—like an x-ray. You can:

• Cached Version: View the local JSON-LD representation stored in the Ktistec database
• Remote Version: Fetch and view the original JSON-LD representation from the source server
• Navigation: Click on any ActivityPub IRI to navigate to that object
• History: Use Alt+Left and Alt+Right to navigate through your viewing history

This feature is useful for debugging federation issues, understanding ActivityPub structures, and verifying how content is stored and represented.

Here's the full changelog for the release:

Added

• Support for pinned posts and the Mastodon "featured posts" collection.
• X-Ray Mode for viewing and navigating JSON-LD resource (actor, object, etc.) representations.
• Back links on thread pages for easier navigation. (fixes #1)
• License page for LibreJS compliance. (fixes #127)
• Highlighting of recently fetched hashtagged posts.

Changed

• Improved presentation of audio and video media.
• Refactored theming/styling implementation.

The next release will focus on smaller features and bug fixes.

Enjoy!

Release v3.2.1 of Ktistec adds support for bookmarking posts. This was so immediately useful I don't know why it took me so long to get around to it!

Pinned/featured posts are in the works for the next release.

The full changelog:

Added

• Support for bookmarking posts.

Fixed

• Invalidate user's sessions after changing password.
• Ignore supplied languages that don't conform to expected format.

Changed

• Upgrade Kemal.

In other thoughts... I'd like to make followed hashtags more consumable. I follow ~10 hashtags and: 1) it's hard to tell what's new, 2) it feels like they arrive in large batches that are difficult to digest, and 3) the reading experience is meh.

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!

Vacations are wonderful. It is a privilege to be able to travel without worry. It's also wonderful to be home, and to have the time to work on projects I care about. With those thoughts in mind, I present release v3.1.1 of Ktistec, an ActivityPub server written in the Crystal programming language!

This release is a mixed bag of small features and improvements:

Added

• Auto-link URLs in posts. (fixes #24)
• Support searching by actor username. (fixes #102)
• Support hourly granularity in metrics charts.

Fixed

• Mark actor as down if refresh fails.
• Remove draft posts from the everything collection.
• Ignore charts with no points in the date range.
• Ensure HTTP::Client instances are closed.

I added support for multiple users at the beginning of the month. I'm very interested in feedback on how that's working out for anyone using it.

This release of Ktistec merges the main_3.x branch into the main branch.

Managing two branches, and two releases, was a lot of work. And sometimes changes were lost in the shuffle, like:

Added

• Add a small banner to highlight "offline" status.
• Support YAML MCP prompts and hot-reloading.

I have about a dozen more features and fixes that are ready for the next release, but to keep things simple, I'm doing the merge first, in its own commit.

#ktistec #fediverse #activitypub #crystallang

I'm trying to decide how much of "quote posts" I want to support in Ktistec. On one hand, it's not trivial functionality, and I really do question how much extra value someone's comments on someone else's post will add to the Fediverse. On the other hand, I dunno... assuming Mastodon limits abuse by enforcing quoting rules, Ktistec could probably just follow along and display quoted posts. Is there any value in just that?

#ktistec #activitypub #fediverse

Release v2.4.16 of Ktistec... because I forgot to include some critical code in v2.4.15... namely, the menu.

Changed

• Reorganize the admin menu.

If you're not planning on adding additional users, you don't need to update!
