What is Kavita?

Kavita overhauls its Kavita+ premium tier and integrates Hardcover for book recommendations, its most significant monetization move in three years.

Kavita v0.9.1 delivers a complete redesign of Kavita+, the platform's premium subscription layer. The Hardcover integration — adding OAuth login and recommendation support — arrived alongside Hardcover's own launch of OAuth and Vibes recommendations, with v0.9.1.4 required to enable recommendations. The 50x scanner performance improvement from v0.8.9 continues to pay dividends for large libraries.

What is SOGo?

SOGo's 5.12 line keeps shipping security fixes, now with mandatory settings attached.

SOGo, Alinto's self-hosted webmail, calendar and contacts suite, has made most 2026 releases about security. v5.12.11 in September fixed password reset poisoning and several XSS injections, and made a SOGoPasswordRecoveryBaseURLs setting mandatory when password recovery is on, with a warning that the XSS fix may affect webmail display. v5.12.12 in October fixed another major vulnerability and now verifies LDAP TLS certificates by default.

6.3

Kavita overhauls its Kavita+ premium tier and integrates Hardcover for book recommendations, its most significant monetization move in three years.

◆ Current state

Kavita v0.9.1 delivers a complete redesign of Kavita+, the platform's premium subscription layer. The Hardcover integration — adding OAuth login and recommendation support — arrived alongside Hardcover's own launch of OAuth and Vibes recommendations, with v0.9.1.4 required to enable recommendations. The 50x scanner performance improvement from v0.8.9 continues to pay dividends for large libraries.

◆ Where it's heading

The Kavita+ overhaul repositions the premium tier from a metadata downloader into a connected reading ecosystem. Hardcover integration is the first external service partnership for Kavita+, suggesting the project is moving beyond a standalone reader toward a recommendation and discovery layer. The recurring pattern of epub reader and reading experience improvements reflects a platform that has matured past basic library management.

◆ Prediction

Kavita will deepen the Hardcover integration with additional recommendation signals and expand Kavita+ to include connections to other reading platforms — likely Anilist or similar — as the subscription layer evolves from metadata tools to a reading discovery platform.

2.5

SOGo's 5.12 line keeps shipping security fixes, now with mandatory settings attached.

◆ Current state

SOGo, Alinto's self-hosted webmail, calendar and contacts suite, has made most 2026 releases about security. v5.12.11 in September fixed password reset poisoning and several XSS injections, and made a SOGoPasswordRecoveryBaseURLs setting mandatory when password recovery is on, with a warning that the XSS fix may affect webmail display. v5.12.12 in October fixed another major vulnerability and now verifies LDAP TLS certificates by default.

◆ Where it's heading

Fixes are increasingly arriving with secure defaults that break lax configurations, first password recovery URLs and then LDAP certificate checks. Feature work has been absent since 5.12.4 a year ago.

◆ Prediction

Further 5.12.x security releases are likely; operators should expect more defaults that require configuration changes.
