German blog reader MCG mentioned within this comment (thanks). I checked it on my system. The update was detected during an update search on the Thunderbird Portable and installed without complaint.
The changes can be found in the release notes. The new version no longer focuses on the attachment area of a window of a new mail when files are attached to the mail using a keyboard shortcut. In addition, the following vulnerabilities, some of which are rated 'high', will be removed from this security advisory.
