Tiki is the Free/Libre and Open Source (FLOSS)
web application with the most built-in features.

🎉We are happy to announce the release of Tiki 30 LTS. Another Tiki release is always more than a new version number. It is the result of months of coding, testing, fixing, reviewing, translating, documenting, and discussing, with contributions from people across the Tiki community. Tiki 30 continues that tradition while bringing the platform forward in several important areas. As an LTS (Long-Term Support) release, Tiki 30 provides a stable foundation for organizations looking for a Tiki version to deploy and maintain for the coming years. Modernization under the hood A lot of work in Tiki 30 happens behind the scenes. Dependencies and development tools have been updated, older components have been replaced, and compatibility with newer versions of PHP and other technologies has been improved. This work may not always be visible, but it is important for keeping a platform that has been evolving for more than 20 years healthy and maintainable

We have released Tiki 30.1, Tiki 29.4, Tiki 27.8 and Tiki 24.15 to address vulnerabilities affecting the related branches. These releases include a mix of security fixes and stability improvements. We strongly urges all site administrators to apply these updates immediately. Vulnerable versions include: Tiki 30.0 Tiki 29.3 and earlier Tiki 27.7 and earlier Tiki 24.14 and earlier If you are running any of these versions, please update your website without delay to protect your data, users, and overall system integrity. These releases also include stability improvements that reinforce the long-term reliability of your Tiki instance. What's New?
