Description Nicholas D Steeves 2020-05-28 16:28:30 UTC 
Hi!

Thank you for maintaining KAccounts, and particularly for the recent fixes for Google's changes.

When importing the latest version (20.04 at that time, later 20.04.1) I noticed that many symbols appeared to have been renamed, eg:

- _ZN16KAccountsDPlugin11qt_metacallEN11QMetaObject4CallEiPPv@Base 0.0
+ _ZN13AccountsModel11qt_metacallEN11QMetaObject4CallEiPPv@Base 4:20.04.0

P.S. The trailing version is a Debian (and derivatives)-specific version used for mappings between upstream symbols and Debian package versions.

Please bump ABI for 20.04.2, and I'll package it as soon as it's ready.  If you're interested in the Debian side of the discussion, it happened here:

Thank you,
Nicholas

Note that the actual ABI change is not what Nicholas mention, but rather this:
