Currents vs Sonarr: at a glance
What is Currents?
Currents now lets agents walk a Playwright trace instead of downloading it.
Currents is a Playwright test dashboard rebuilding itself around agent access. In six weeks it shipped agent-readable failure links, scoped personal access tokens, a hosted MCP server with OAuth, run attachments, and now a trace API built for agents. The trace API lets an agent read a Playwright trace one part at a time, choosing each next call from what it just read.
What is Sonarr?
Sonarr's 5.0 builds move from UI rework to safer restores and keyboard-friendly selects.
Sonarr is iterating on 5.0 builds while 4.0.x receives only occasional patches. 5.0.0.2569 removed Basic Auth, defunct IMDb lists and Kometa metadata, and 5.0.0.2608 fails executables and risky files by default for most indexers. 5.0.0.2635 reworked the UI from Discord feedback, and 5.0.0.2668 now validates a restored database and keeps the previous one until the restore completes, alongside keyboard shortcut fixes and type-ahead in selects.

Currents

Currents now lets agents walk a Playwright trace instead of downloading it.
◆ Current state
Currents is a Playwright test dashboard rebuilding itself around agent access. In six weeks it shipped agent-readable failure links, scoped personal access tokens, a hosted MCP server with OAuth, run attachments, and now a trace API built for agents. The trace API lets an agent read a Playwright trace one part at a time, choosing each next call from what it just read.
◆ Where it's heading
The sequence goes deeper each time: from a failure summary an agent can fetch, to a secure way in, to the logs around a run, to the trace itself. Currents is positioning as the place a coding agent goes to debug a CI failure, with humans as a second audience.
◆ Prediction
The likely next step is wiring the trace API and attachments into the MCP server so one agent session can reach all of it. The entries don't yet confirm that the trace API is exposed through MCP.
Sonarr
5.0INFRA · APIS
Sonarr's 5.0 builds move from UI rework to safer restores and keyboard-friendly selects.
◆ Current state
Sonarr is iterating on 5.0 builds while 4.0.x receives only occasional patches. 5.0.0.2569 removed Basic Auth, defunct IMDb lists and Kometa metadata, and 5.0.0.2608 fails executables and risky files by default for most indexers. 5.0.0.2635 reworked the UI from Discord feedback, and 5.0.0.2668 now validates a restored database and keeps the previous one until the restore completes, alongside keyboard shortcut fixes and type-ahead in selects.
◆ Where it's heading
5.0 is a hardening release: legacy auth and integrations gone, safer handling of what downloads may land, and now a safer restore path. Four builds in six days, each mixing fixes with small UX work, point to a testing phase that is narrowing toward polish rather than adding scope.
◆ Prediction
Expect more 5.0.0 builds focused on UI fixes and edge cases; when 5.0 replaces 4.x as the default track is not clear from these entries.
