aurweb 4.8.0 released

[Lukas Fleischer]

Dear aurweb contributors and users,

This is a bit of a late announcement but we are pleased to announce that
aurweb 4.8.0 has been released last week!

Several bugs have been fixed, we made some significant performance
improvements by caching results of expensive database queries, and a
simple CAPTCHA has been added to combat the growing number of spam
accounts.

For a comprehensive list of changes, please consult the Git log [2]. As
usual, bugs should be reported to the aurweb bug tracker [3].
