Tiki 15 is a Long-Term Support (LTS) version of Tiki Wiki CMS Groupware that was first released in April 2016 and received 9 incremental updates, the most recent in mid-2020. Tiki 15 has reached the end of its service life, as shown by Version Lifecycle. This means The Tiki Community will no longer provide fixes or updates for Tiki 15, so users are encouraged to upgrade to the latest Long Term Support version - Tiki 21 as of this writing.

Any organization using Tiki 15 that wishes to continue using that version and not miss out on security fixes and other code maintenance is encouraged to select a qualified Tiki consultant.

Avan.tech offers professional enterprise support

In particular, we would like to announce that Avan.tech has come forward to offer enterprise LTS support for Tiki 15. Avan.tech is also offering extended enterprise support for other past and future LTS versions of Tiki. If interested, please contact them directly. We are appreciative and excited that for the first time Tiki LTS versions will be privately supported for a period of up to 10 years. This will not affect the release cycles of Tiki, and our current period of five years of LTS support will be maintained for future Tiki releases.
