[Dave Brondsema <br...@apache.org>]

The Apache Allura team is pleased to announce the release of Apache Allura 1.15.0

Apache Allura is an open source implementation of a software forge, a web site 
that manages source code repositories, bug reports, discussions, wiki pages, 
blogs, and more for any number of individual projects.

1.15.0 adds support for more Python versions (see next section) and 
Content-Security-Policy headers. Many other fixes and improvements are also 
included, they relate to SEO, performance and different parts of Allura.

This release supports Python 3.7 through Python 3.11

The next release will drop support for Python 3.7 so please upgrade your Python 
version soon, to stay compatible with future Allura releases.
