I have released the standalone version of Sherpa 4.5.0 at the Sherpa website:
in past releases, the purpose is to allow Python users to install
Sherpa as a Python module, without reference to any other CIAO package
I release the source code tarball, sherpa-4.5.0.tar.gz, that contains all the Sherpa source code we released with CIAO 4.5. Release notes can be found at NOTES-4.5.0.txt. The new version is also available at the cxcdev github repository for Sherpa.
This is a major release, to sync the standalone version with the recent CIAO 4.5 release.
