The file /usr/share/doc/insync/changelog.gz installed with Arch Linux is not a changelog.
I’m searching for the changes between versions and I couldn’t find it, not even online.
Tagging our engineer @jimperio and he will get back to you
Hi @hsantanna, Insync has an in-app changelog in the app window: [+] menu -> Support -> Release notes.
I will also take a look however at that changelog.gz file and get back to you.
