A side-by-side editorial comparison of EGroupware and Prowlarr — release velocity, themes, recent moves, and the top alternatives to consider.
EGroupware is pushing its old branch off a cliff on 15 August, and sweetening the landing with passkeys.
Releases arrive in pairs — one for the 23.1 branch, one for the current 26.x — usually within minutes of each other and usually flagged SECURITY. The 23.1 notes have carried an end-of-support warning for weeks; coverage stops on 15 August 2026. The 26.x side of each pair carries the actual product work: WebAuthN as a second factor, CalDAV timezone and recurrence fixes, invoice XML exemption codes, OpenID library upgrades.
A steady indexer-maintenance cadence: fixes, definitions, translations, repeat.
Prowlarr ships every week or two off the develop branch, and the entries are consistently small: indexer definition corrections, parsing fixes, dependency bumps and Weblate translation batches. The only user-facing addition in this window is showing indexer-specific categories in search. Every entry opens with the same boilerplate about switching update branches, which is the feed's own shape rather than news.

The 26.x side of each pair carries the actual product work: WebAuthN as a second factor, CalDAV timezone and recurrence fixes, invoice XML exemption codes, OpenID library upgrades.
The pattern is a forced migration executed through security cadence rather than announcement. Each paired release makes the gap wider: 23.1 receives the fix, 26.x receives the fix plus features, and the deadline text repeats. Underneath, the substantive work is authentication — WebAuthN, OpenID Connect verification fixes, email_verified handling — for a self-hosted suite whose buyers care about exactly that.
Expect one or two more 23.1 security releases before 15 August and then nothing, with the paired-release rhythm collapsing to a single 26.x train afterwards.

The only user-facing addition in this window is showing indexer-specific categories in search. Every entry opens with the same boilerplate about switching update branches, which is the feed's own shape rather than news.
The value being shipped is upkeep of the indexer catalogue — PreToMe categories, M-Team category updates, MyAnonamouse author name handling, IPTorrents query parameters. That is the actual product for an indexer manager, but it means the release history reads flat: no architectural change, no new integration surface, no shift in what Prowlarr does. Version numbers move faster than capability.
Expect the same rhythm — per-indexer definition fixes and dependency bumps cut every one to two weeks — with any notable change arriving as a small search or UI addition rather than a release theme.
