Hi Viacheslav,

The commit in the 'Fixes' line is the commit that announces the deprecation
notice, sure this patch is not fixing it.

I am removing the above 'Fixes' line.

This patch is breaking the ABI and it can't be backported anyway, but
the 'Fixes' line still can be useful for documentation purpose, so if there
is valid fix commits please share them and I can squash them in next-net.
