What is ArchivesSpace?

An archives platform whose big releases are infrastructure debt being paid down

ArchivesSpace publishes release candidates rather than a continuous stream, and the two substantive entries here bracket its recent history. v4.0.0-RC1 was an infrastructure release — Bootstrap, Rails, JRuby, jQuery and Jetty all moved forward, the staff CSS migrated from less to sass, and specs were ported to capybara. v4.2.0-RC1 is the opposite in scale: bug fixes plus small configurable options for the staff and public interfaces.

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.

ArchivesSpace vs Radarr: editorial side-by-side

A0.0

An archives platform whose big releases are infrastructure debt being paid down

◆ Current state

ArchivesSpace publishes release candidates rather than a continuous stream, and the two substantive entries here bracket its recent history. v4.0.0-RC1 was an infrastructure release — Bootstrap, Rails, JRuby, jQuery and Jetty all moved forward, the staff CSS migrated from less to sass, and specs were ported to capybara. v4.2.0-RC1 is the opposite in scale: bug fixes plus small configurable options for the staff and public interfaces.

◆ Where it's heading

The pattern is a maintained institutional application, not a product chasing new capability. The 4.0 work was explicitly framed as changes users would barely notice but that unblock future development, and 4.2 spends its budget on the specific friction archivists hit — mobile PDF downloads, setting users inactive, controlling which fields carry over when duplicating a resource. Configuration options rather than features is the recurring shape.

◆ Prediction

Expect 4.2.0 to reach a final release with the RC contents intact, and subsequent releases to continue mixing small interface fixes with periodic dependency modernization.

5.0

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.
