Another issue that comes up is that with 1.9 being GPLv2+ and 1.10
now GPLv3+ it is no longer possible to link GPLv2 only programs
(such as those linking against the Qt libraries) against 1.10.  A nice
solution would be to install 1.9 in parallel to 1.10, but as they share
the same SONAME the dynamic linker cannot distinguish them :/

I wish you had bumped the shared library major version for the
license change from GPLv2+ to GPLv3+.  Now distributors are forced to
either stay with 1.9 or introduce a distribution-local SONAME for
the 1.10 version.
