Ginga v2.6.0
With release 2.6.0 we are moving to a new versioning scheme that makes
use of github tagged releases and a "dev" versioning scheme for updates
between releases.
This release includes many bugfixes and improvements, new canvas types
(XRange and YRange), a Command plugin, WCSMatch plugin, dynamically
configurable workspaces, OpenCv acceleration, an HTML5 backend and much
much more.
