I downloaded and installed LibreOffice 5.2.0 beta2 as described in LibreOffice 5.2.0 beta2 as a snap package. It weighed in at 1015 MiB.
There will certainly be more updates before the RC is out. My question is this: will snap packages get differential (delta) updates or will the entire snap package, 1 GiB in this case, have to be downloaded each time?
(BTW: this version fixes the long-standing vanishing clipboard content issue!)
Postscript question: I want to know if I can delete
libreoffice_22.214.171.124.beta2_amd64.snap, the 1 GiB "source" file, or must it remain on the system for the delta updates to work?
