on icon on my L5 desktop disappearde. It first letter must be something between A nd F, because I noted that the icons shifted one position to the left (see screen shot): Firefox was before where now Foliate is and Goodvibes was were now Gscriptor is. The move of the location of Goodvibes which I start often called my attention, What icon could it be and why the update removed something?
The scripts were not removed, but the desktop icons are no longer visible. They can still be invoked via terminal, with the commands: l5-contacts-importer file.vcf and l5-contacts-exporter
The reason for this is that gnome-contacts now supports importing and exporting contacts. The contacts handling scripts in the package librem5-goodies were always seen (at least by me) as a stopgap until gnome-contacts had this feature.
The reason why the scripts were not completely removed, just had the desktop icon hidden, is that there are still two things that these scripts can do that gnome-contacts does not:
import and export contacts in batch via a terminal
import vcard (contacts) via bluetooth (which is useful for some users migrating data from other devices)
But if you want you can have the icons showing up again in the app tray, by copying the files
