The latest version should have all modifications included in it. I would recommend taking a backup first just in case
Most of the changes we made related to the locations manager and that has not been updated. Please wait a couple of hours though since verison 3.4.53 needs to be released to fix a repeating events editing problem
I have problems with this new version.
Once I have Joomla Normal Caching enabled, which is the standard setting of my site, I am getting a "Call to a member function get() on null" error. If I disable caching, it is working.
I am using Jevents since many years but never had such issue.
