The latest stable version of Kayako Classic is 4.98.9. We advise using this version for optimal performance and compatibility.
We released version 4.99.x with the intention of supporting PHP 8.2.1, as detailed in our Kayako Classic Server Configuration and System Requirements. However, this update encountered several complexities, leading to stability issues in the 4.99.x versions. For reference, you might encounter errors like "Cannot access protected property" after upgrading to version 4.99.8.
In light of these challenges, our focus has shifted towards maintaining the stability and security of the currently stable version, 4.98.9, which supports PHP 7.3.x.
