Version 1.8.2 changes - Safari is.....
The list of supported browsers for Mango has been greatly relaxed. It is now assumed that future versions of already supported browsers will also be supported. Also, Safari is not officially supported as well.
Did you mean "Safari is now officially supported as well"
Please note that Serotonin has limited resources for completely testing various browser and platform combinations. The only browser that we can "officially support" is Firefox, which is what is nearly exclusively used for Mango development.
Let's say that other browsers like Safari are "unofficially supported", meaning that we are happy to hear reports of ways in which they do not work, but cannot guarantee that any such problems will be fixed promptly, if at all.
