    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. β€œInteresting” 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 fastβ€”I anticipated needing to cache analyses, but analyzing a thread with over 400 posts takes only about 50 milliseconds on my production server.Figure 1: Screenshot of the final design. Notable branches link to subsets of the thread.This release also addresses an object visibility regression that was introduced in a previous version.Full ChangelogAddedThread analysis that displays key participants, a timeline histogram, and notable branchesNew MCP tools: analyze_thread and get_threadFocal point rendering support for image attachmentsFixedRegression in object visibility affecting replies to threadsChangedEnhanced MCP tool details for likes, dislikes, and announcesImproved cookie security.#ktistec #fediverse #activitypub #crystallang
