EGroupware vs Komga: at a glance
What is EGroupware?
EGroupware retires 23.1 and keeps shipping security fixes every week or two.
EGroupware shipped six 26.x releases in October, five flagged as security updates, including a critical fix plus a TinyMCE patch on 30 October. The final 23.1 release on 21 October closes that branch. Feature work continues in mail: unseen mail on top, delayed mark-as-read, a warning on large To/Cc lists with a move-to-Bcc offer, resolving distribution lists, and browser-side OCR for invoice PDFs that removes the Tika dependency.
What is Komga?
Komga's NextUI beta keeps gaining features while the old UI gets only translations.
Komga ships every one to two weeks, and almost all feature work lands in NextUI, the rewritten web interface served at /next. The third NextUI beta in 1.28.0 added contextual navigation, such as moving between books in a series or read list, and 1.29.0 added Notable Entities metadata that only NextUI shows. The latest patches fix page counts and KOReader hashes and carry dependency and translation updates.

EGroupware
5.0COLLAB
EGroupware retires 23.1 and keeps shipping security fixes every week or two.
◆ Current state
EGroupware shipped six 26.x releases in October, five flagged as security updates, including a critical fix plus a TinyMCE patch on 30 October. The final 23.1 release on 21 October closes that branch. Feature work continues in mail: unseen mail on top, delayed mark-as-read, a warning on large To/Cc lists with a move-to-Bcc offer, resolving distribution lists, and browser-side OCR for invoice PDFs that removes the Tika dependency.
◆ Where it's heading
Security releases arrive at a near-weekly rate alongside steady mail client polish, now on a single supported branch. The invoice OCR change moves processing into the browser to shed a server dependency.
◆ Prediction
More security-led 26.x releases are near certain; with 23.1 retired, the work should concentrate fully on 26.
Komga
5.0COLLAB
Komga's NextUI beta keeps gaining features while the old UI gets only translations.
◆ Current state
Komga ships every one to two weeks, and almost all feature work lands in NextUI, the rewritten web interface served at /next. The third NextUI beta in 1.28.0 added contextual navigation, such as moving between books in a series or read list, and 1.29.0 added Notable Entities metadata that only NextUI shows. The latest patches fix page counts and KOReader hashes and carry dependency and translation updates.
◆ Where it's heading
NextUI is moving from preview to the main interface: each minor release adds features exclusive to it, and the old web UI now receives only translations and dependency bumps. The server side keeps adding API checks and Kobo sync fixes underneath.
◆ Prediction
Expect further NextUI betas with editing and navigation features, and eventually a release that makes NextUI the default; the entries don't give a date.
