Tiki 25, our biggest release ever in terms of new features and technical upgrades, was completed after nine months of intense development, a fitting conclusion to Tiki's 20th year of continuous development.

Some Tiki releases were characterized by big new features, some by big revamps of existing features, and some by big interface upgrades. Tiki 25 is notable for advancing in all three of these ways.

This release is available for download or installation via git or Tiki Manager. The PHP requirement remains at version 7.4. See https://doc.tiki.org/Tiki25 for full details.

Many thanks to all who contributed to bringing Tiki 25 to completion at a challenging time, demonstrating the antifragility of our "wiki way" of software development.

Read on for more specifics about version 25 of Tiki.

Websites running Tiki 21 should be upgraded to Tiki 21.7 to take advantage of bug and security fixes. Tiki 21.7 is available here: https://sourceforge.net/projects/tikiwiki/files/Tiki_21.x_UY_Scuti/21.7/.

Tiki 18 LTS was first released in January of 2018 and so in January, 2023 it will reach the end of its service life. This means it will no longer be maintained by the Tiki Community, and no longer receive security fixes or feature updates. Tiki 18 users are urged to upgrade their site to the latest Tiki Long-Term Support (LTS) version. Organizations that for some reason choose to continue using Tiki 18 can seek professional enterprise support from a Tiki consultant.

Tiki 24.2 was released on September 23, a quick but necessary update to the most advanced Tiki Long-Term Support version. Tiki 24.1 was released just a month ago, but websites using that version should be updated to version 24.2. We apologize for any inconvenience caused by the timing of this update.

On August 23, 2022, Tiki 18.9 LTS, Tiki 23.2 and Tiki 24.1 LTS were released, and Tiki 21.6 LTS was released the next day. These releases bring functional enhancements, bug fixes and security updates.

Tiki 24.1 LTS has received improvements and enhancements in trackers, calendars, web mail, newsletters, toolbars, wiki structures (page sets), French translations and many other areas.

For Tiki 21.6 LTS, there was some cleanup of old code as well as miscellaneous minor fixes and enhancements.

For users of Tiki 23, the update includes improvements and fixes in wiki plugins, trackers, maps, CKEditor functions, and user registration, among others. This is essentially an end-of-life release so users of Tiki 23 should consider upgrading to Tiki 24.

Tiki 18 LTS was updated for probably the last time as it is approaching the end of its service life. For more information, please see End of service life approaching for Tiki 18 - what options do you have?.

The releases include a fix for a security vulnerability reported by Egidio Romano (aka EgiX), whom we deeply thank for his detailed report.
