Maybe there have been improvements, but I'm not aware of issues in the
latest release either.

I have not checked whether it builds against the current libnl snapshot
since it is too much of a moving target with incompatible API changes
and no easy version etc. defines that could be used to automatically fix
the application builds. It used to be possible to build hostapd against
a libnl snapshot at the time when the forward compatibility code was
added into driver_nl80211.c.

As long as a library keeps changing its API in ways that are not even
trying to be backwards compatible, does not provide any defines to
allow this to be handled cleanly, and the author does not reply to
questions and suggestions to improve this situation, then yes, I'm not
very interested in doing the development work before the next release
is available or at least there is reasonable expectation on the new API
being frozen for 2.0 release.

Naming used here may not be clear enough if you have not been following
the development process in the past, but yes, hostap.git is indeed the
development branch and continues to be that. hostap-*.git will be stable
branches which will be created more or less when a stable release is
created. Stable release updates like 0.6.8 and 0.6.9 are only available
from the stable branches, not from the main development repository.
