Radarr vs SiYuan: at a glance
What is Radarr?
Radarr's 7.0 pre-release line now shows every audio and subtitle stream per file.
Radarr's 7.0 pre-release line is on its third build. 7.0.0 moved the app to .NET 10 and added OIDC login, PEM certificates and Trakt Smart List imports, and 7.0.1 lists every audio and subtitle stream per file. 7.0.2 adds Happy Eyeballs connection handling, custom ntfy headers, qBittorrent single-file imports from the root path, and stops logging the Postgres password during migration. The main branch is still on 6.4.4.
What is SiYuan?
SiYuan 3.8.11 alphas add freeform mind maps and plugin snapshots right after 3.8.10.
SiYuan pushed 3.8.10 through betas and release candidates between November 7 and 9, carrying workspace AI memory, database sub-items and a built-in Markdown editor. The 3.8.11 alphas followed within days: freeform mind map relationships with per-node connector styles, browsing and restoring plugin snapshots, excluding assets from cleanup, a built-in date picker and rich text in database primary keys. Alpha 4 adds search and replace in the standalone Markdown editor.

Radarr
5.0COLLAB
Radarr's 7.0 pre-release line now shows every audio and subtitle stream per file.
◆ Current state
Radarr's 7.0 pre-release line is on its third build. 7.0.0 moved the app to .NET 10 and added OIDC login, PEM certificates and Trakt Smart List imports, and 7.0.1 lists every audio and subtitle stream per file. 7.0.2 adds Happy Eyeballs connection handling, custom ntfy headers, qBittorrent single-file imports from the root path, and stops logging the Postgres password during migration. The main branch is still on 6.4.4.
◆ Where it's heading
The 7.0 cycle pairs a platform upgrade with deeper file-level detail: media info, import diagnostics and download-client labels. The media info migration was split into batches to avoid running out of memory, which shows the team is hardening the upgrade path for large libraries before a stable release.
◆ Prediction
More 7.0.x pre-release builds with import and media info fixes are likely before 7.0 reaches the main branch; the entries do not show a date for that promotion.
SiYuan
5.0COLLAB
SiYuan 3.8.11 alphas add freeform mind maps and plugin snapshots right after 3.8.10.
◆ Current state
SiYuan pushed 3.8.10 through betas and release candidates between November 7 and 9, carrying workspace AI memory, database sub-items and a built-in Markdown editor. The 3.8.11 alphas followed within days: freeform mind map relationships with per-node connector styles, browsing and restoring plugin snapshots, excluding assets from cleanup, a built-in date picker and rich text in database primary keys. Alpha 4 adds search and replace in the standalone Markdown editor.
◆ Where it's heading
SiYuan works in fast public cycles, with the next version's alphas starting as soon as the last one stabilises. 3.8.11 is about polish and editing depth: mind maps, databases and the new Markdown editor all get more control.
◆ Prediction
Expect more 3.8.11 alphas, then betas and release candidates with the same list, following the 3.8.10 pattern.
