The changelog generation scripts used for releases are overly elaborate
and fragile. A Changelog is also no substitute for the Git log so now we
simply ship a static Changelog that points to the Git log instead.
The check for the version number was checking against the 2.0.0 micro
version number which isn't expected to change for a long time so the
test was useless.
The release template had the wrong version number and download URL and
the subject was slightly different from what we used in the previous
release. Also the parts split out from the README were including the
-- separator. These have been removed using tail -n +1. The
documentation section is updated to match the message used for the
1.7.0 release. There is now a note about the release being a
development snapshot that only gets added depending on
COGL_RELEASE_STATUS.
This explicitly renames the cogl-2.0 reference manual to
cogl-2.0-experimental and renames the cogl-2.0 pkg-config file to
cogl-2.0-experimental.pc. Hopefully this should avoid
miss-understandings.
