We are tw:DogFooding Tiki4 for the community site, documentation and developers's site.

The big question: "when should I upgrade?"

As with any software, new features can bring new bugs, or compatibility/upgrade issues.

If you are starting a new project, you should use Tiki 4.0

  • There are many improvements
  • Upgrades to Tiki 4.1, 4.2, are quite easy.


If you are already running a simple Tiki site (ex.: 3.x or 2.x)

  • Install Tiki 4.0 on a test site with backup data
  • Test, test, test.
    • If it all works fine for the features you are using, upgrade
    • If you find issues, please report them (and fix/contribute if you can)


If you are already running an advanced/complex Tiki site (ex.: 3.x or 2.x) and you can't test an upgrade, it would be wise to wait for Tiki 4.1
