Prowlarr vs SiYuan: at a glance
What is Prowlarr?
A steady indexer-maintenance cadence: fixes, definitions, translations, repeat.
Prowlarr ships every week or two off the develop branch, and the entries are consistently small: indexer definition corrections, parsing fixes, dependency bumps and Weblate translation batches. The only user-facing addition in this window is showing indexer-specific categories in search. Every entry opens with the same boilerplate about switching update branches, which is the feed's own shape rather than news.
What is SiYuan?
SiYuan stabilises 3.8.1 after a seven-build beta run, all of it widening the agent surface it opened in 3.8.0
SiYuan has just cut 3.8.1 stable, the endpoint of a beta chain that ran six builds in five days. The release groups into three areas: AI integration work - custom editor actions syncing across devices, an Agent panel shortcut, user-level skills read from a shared agents directory, nested rerank API formats and OpenAI Responses API support; editing and database throughput, including virtualised grouped-table rendering and faster document loading; and cross-platform reliability covering HEIF/HEIC previews, PDF export and mobile behaviour. A batch of MCP and publishing-service fixes rounds it out.

Prowlarr
5.0COLLAB
A steady indexer-maintenance cadence: fixes, definitions, translations, repeat.
◆ Current state
Prowlarr ships every week or two off the develop branch, and the entries are consistently small: indexer definition corrections, parsing fixes, dependency bumps and Weblate translation batches. The only user-facing addition in this window is showing indexer-specific categories in search. Every entry opens with the same boilerplate about switching update branches, which is the feed's own shape rather than news.
◆ Where it's heading
The value being shipped is upkeep of the indexer catalogue — PreToMe categories, M-Team category updates, MyAnonamouse author name handling, IPTorrents query parameters. That is the actual product for an indexer manager, but it means the release history reads flat: no architectural change, no new integration surface, no shift in what Prowlarr does. Version numbers move faster than capability.
◆ Prediction
Expect the same rhythm — per-indexer definition fixes and dependency bumps cut every one to two weeks — with any notable change arriving as a small search or UI addition rather than a release theme.
SiYuan
6.3COLLAB
SiYuan stabilises 3.8.1 after a seven-build beta run, all of it widening the agent surface it opened in 3.8.0
◆ Current state
SiYuan has just cut 3.8.1 stable, the endpoint of a beta chain that ran six builds in five days. The release groups into three areas: AI integration work - custom editor actions syncing across devices, an Agent panel shortcut, user-level skills read from a shared agents directory, nested rerank API formats and OpenAI Responses API support; editing and database throughput, including virtualised grouped-table rendering and faster document loading; and cross-platform reliability covering HEIF/HEIC previews, PDF export and mobile behaviour. A batch of MCP and publishing-service fixes rounds it out.
◆ Where it's heading
This is consolidation of the surface 3.8.0 opened, not an extension of it. The agent, semantic search and MCP endpoint arrived in the 3.8.0 line; 3.8.1 makes them portable and pluggable - skills come from a directory the user controls, editor actions follow the user between devices, and the provider layer now speaks the OpenAI Responses API rather than one bespoke shape. The high beta count against a modest final diff shows a project stabilising a young subsystem rather than building a new one.
◆ Prediction
The next line most likely pushes on the skills directory - discovery, sharing or marketplace distribution of user-level skills - since that is the piece 3.8.1 made user-editable without giving it a distribution path.
