Caddy vs Sonarr: at a glance
What is Caddy?
Caddy 2.11's betas add ECH key rotation and a release process without its founder.
Caddy's tracked entries are the two 2.11 betas from December 2025 and January 2026. Beta 1 was the first release cut by the maintainer team's automated process without the original author, and brought time-based log rolling, argon2id basic auth and named socket activation. Beta 2 added ECH key rotation, multiple intermediates in PKI signing chains and a fix for the ZeroSSL issuer.
What is Sonarr?
Sonarr's 5.0 builds keep cycling through tester feedback toward release.
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; 5.0.0.2608 fails executables and risky files by default for most indexers. 5.0.0.2635 follows with UI changes from Discord feedback, disabled response caching on authentication endpoints, and fixes for calendar search, bulk tag removal and color-impaired mode.

Caddy 2.11's betas add ECH key rotation and a release process without its founder.
◆ Current state
Caddy's tracked entries are the two 2.11 betas from December 2025 and January 2026. Beta 1 was the first release cut by the maintainer team's automated process without the original author, and brought time-based log rolling, argon2id basic auth and named socket activation. Beta 2 added ECH key rotation, multiple intermediates in PKI signing chains and a fix for the ZeroSSL issuer.
◆ Where it's heading
Caddy is investing in privacy-preserving TLS through Encrypted ClientHello, and in project continuity through a team-run release pipeline. The rest of the betas are edge-case fixes, consistent with a mature server polishing details.
◆ Prediction
The beta notes point to a 2.11 stable release; no newer entries are tracked, so its timing isn't visible here.
Sonarr
5.0INFRA · APIS
Sonarr's 5.0 builds keep cycling through tester feedback toward release.
◆ 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; 5.0.0.2608 fails executables and risky files by default for most indexers. 5.0.0.2635 follows with UI changes from Discord feedback, disabled response caching on authentication endpoints, and fixes for calendar search, bulk tag removal and color-impaired mode.
◆ Where it's heading
5.0 is a hardening release: legacy auth and integrations gone, safer handling of what downloads may land, and a new UI being reworked in public. Three builds in four days, each answering user feedback, point to an active testing phase rather than a long-lived branch.
◆ Prediction
Expect more 5.0.0 builds with UI polish and fixes; when 5.0 replaces 4.x as the default track is not clear from these entries.
