As of XenForo v1.4 beta 3 I'm not able to install my Calendar add-on located here:

https://xenforo.com/community/resources/calendar.2675/

During the "Install New Add-on" procedure I click the Install Add-on button and I get the following message:

Code:
Please enter an ID using only a-z, A-Z, 0-9, and _ characters.
At first I thought the XML file name was the issue, but even if i rename the file to Calendar.xml the problem persists.
