• Fix #345: Crash during cropping of photos with X-ABCROP-RECTANGLE parameter when error occurred during crop, e.g. picture format not supported by php-gd.
• New: When exporting a VCard from a carddav addressbook, the export is now handled by rcmcarddav. The exported card is exactly the card on the server, including any properties not supported by roundcube / rcmcarddav. The only exception is the photo property: photos referenced by URI will be downloaded and stored inside the card; photos with X-ABCROP-RECTANGLE will be stored cropped. This is to improve interoperability with the importing application.
• Fix #345: When exporting a VCard from a carddav addressbook, the PHOTO property in the exported card contained an invalid value.
