update changelog and make it easier to find

[j]

I just went to https://pypi.python.org/pypi/lockfile and noticed 0.11.0 was released (the last version I used was 0.10.2), so I want to see what's changed.

The long_description rendered to https://pypi.python.org/pypi/lockfile contains a "Documentation" link pointing to http://docs.openstack.org/developer/pylockfile but there's no changelog there. It also contains a "Source" link pointing to http://git.openstack.org/cgit/openstack/pylockfile but the RELEASE-NOTES file there hasn't been updated since 0.9.1 (see http://git.openstack.org/cgit/openstack/pylockfile/tree/RELEASE-NOTES).

There is also a lot of confusion caused by duplicate and unsynchronized content being scattered across a bunch of different places. For example, at the bottom of https://pypi.python.org/pypi/lockfile among the package metadata there is a "lockfile package documentation" link pointing to http://pythonhosted.org/lockfile/ which appears to be an abandoned instance of the sphinx html docs last updated for version 0.9.1. There's also https://github.com/smontanaro/pylockfile and https://github.com/openstack/pylockfile both of whose relationships to the other links are unclear.

Fixing these issues would go a long way toward improving the lockfile getting started experience. Thanks for your consideration.

pylockfile has been retired. We won't be making any more updates to it. See the fasteners library for a supported alternative.
