What is Readarr?

Six releases of small fixes and translations, then nothing since June 2025.

Readarr's last six entries run from March to June 2025 and are uniformly small: a truncated root-folder path, remote image links for posters and covers, NLog message templating, disabled SelectInput options, Weblate translation batches. Every entry opens with the same instructions about switching to the develop branch and not updating inside a running Docker container. Nothing in this window adds capability, and no entry has appeared in over a year.

What is SiYuan?

SiYuan 3.8.9 reaches RC, adding AI-agent extraction of images embedded in PDFs.

SiYuan moved 3.8.9 from beta.6 to rc.1 on Oct 28. The RC's only new item is AI-agent extraction of images embedded in PDFs; the rest of its long list matches beta.5's cumulative notes: pinned agent sessions, backlink filtering by database fields, block-reference collection through database automation, resizable table rows, mind-map themes and node copy/paste, TIFF previews and macOS proxy detection.

Six releases of small fixes and translations, then nothing since June 2025.

◆ Current state

Readarr's last six entries run from March to June 2025 and are uniformly small: a truncated root-folder path, remote image links for posters and covers, NLog message templating, disabled SelectInput options, Weblate translation batches. Every entry opens with the same instructions about switching to the develop branch and not updating inside a running Docker container. Nothing in this window adds capability, and no entry has appeared in over a year.

◆ Where it's heading

The pattern is a project in caretaker mode: auto-generated commit lists, incremental UI corrections, and internal work like using ReflectionOnly types to avoid loading assemblies unnecessarily. Volume held steady at roughly one release every one to two weeks until it stopped entirely. The entries themselves give no reason for the halt.

◆ Prediction

The changelog offers no signal of resumed development; without new entries there is nothing here to project forward beyond the fact that the feed went quiet after 0.4.18.

SiYuan 3.8.9 reaches RC, adding AI-agent extraction of images embedded in PDFs.

◆ Current state

SiYuan moved 3.8.9 from beta.6 to rc.1 on Oct 28. The RC's only new item is AI-agent extraction of images embedded in PDFs; the rest of its long list matches beta.5's cumulative notes: pinned agent sessions, backlink filtering by database fields, block-reference collection through database automation, resizable table rows, mind-map themes and node copy/paste, TIFF previews and macOS proxy detection.

◆ Where it's heading

The 3.8.x line keeps turning databases and mind maps into structured tools that act on the block graph, and the built-in agent is gaining reach into document content such as PDFs. The release cadence is fast and noisy, with most builds repeating the same cumulative notes.

◆ Prediction

A stable 3.8.9 is likely within days, with little added beyond fixes now that it has reached RC.
