An interim bugfix release was issued to the previous build.
This build fixes the issue originating from the change in preferences handling between 1.7.1 and earlier releases and the 1.8.x branch.
An about dialog is also added, and some minor tweaks were added to the task display, to show more concise results on the timeline list.
The release is available at the release page, on GitHub and on SourceForge.
