[Maria-developers] ABI breakage in Connector/C sometime between 2.0.0 and 2.2.2

While preparing Debian packaging for MariaDB Connector/C version 2.2.2, I noticed that there's an ABI breakage without a corresponding change of SONAME: version 2.0.0 had a symbol "get_tty_password@Base" whereas version 2.2.2 doesn't. I'm wondering how big of a breakage it is - i.e. is that something that was never meant to be in the API/ABI in the first place, or is an oversight? I'm also wondering whether it's worth renaming the Debian package from libmariadb2 to libmariadb2a because of this. -- Daniel Schepler
