Hi,

hard to trigger, or they affect non-default configurations (ie: Python3)
There is no urgency to update if you were not affected.

* fix multiple bandwidth limits shown as selected in menu
* fix HTML5 initial focus issue

* fix handling of special characters in filenames from drag and drop
* fix stale xauth lock files
