A side-by-side editorial comparison of Corteza and Easy!Appointments — release velocity, themes, recent moves, and the top alternatives to consider.
Corteza 2026.9.0 goes final after a week of single-fix candidates.
Corteza shipped 2026.9.0 on October 19, closing a run of release candidates that each fixed one edge: MySQL 8 cast checks in rc.4, deny rules in permission reports in rc.5 and MySQL-compatible reminder timestamps in rc.6. The release entry only links to the 2026.9 changelog. Before this, the feed was a slow patch train on the 2024.9 line, ending at 2024.9.10 in late August.
Easy!Appointments 1.6 lands video conferencing, GDPR tools, and a serious security overhaul across its CalDAV and booking stack.
Easy!Appointments, an open-source self-hosted scheduler, is shipping its 1.6 major version through a long pre-release cycle that has introduced Jitsi and Google Meet integration, CAPTCHA and ALTCHA anti-abuse protection, GDPR features, and a rebuilt CalDAV synchronization stack. The 1.6.1 security hardening pre-release then landed a concentrated batch of serious vulnerability fixes: LDAP injection in directory search, SSRF in CalDAV URL handling, cross-account appointment takeover, provider credential exposure to secretary accounts, and CAPTCHA bypass — a set that suggests the expanded surface area of 1.6.0 brought corresponding security debt.

The jump from 2024.9 to 2026.9 opens a new major line after two years on the old one. Two of the final three fixes targeted MySQL, which suggests the release was validated across database backends. What the new line adds for users still isn't visible in the feed.
Expect 2026.9.x patch releases to follow the same pattern as 2024.9, with occasional fixes over months. Whether 2024.9 keeps receiving patches is unclear from the entries.

The 1.6 release line is expanding Easy!Appointments from a simple booking page into a more complete scheduling platform: video conferencing links, richer calendar sync, GDPR compliance tooling, and hardened multi-provider access controls all move it closer to commercial alternatives. The security work in 1.6.1-beta.1 is as important as the features — self-hosted deployments that serve real customer data need these fixes before anyone should run 1.6 in production.
A stable 1.6.1 release is the next step, clearing the pre-release label once the security fixes are confirmed across the beta testing community. After that, the CalDAV and video conferencing integrations will likely expand — CalDAV push notifications or two-way Google Calendar sync are the natural follow-ons.
