SolidOpt is an open source project with limited funding and our roadmap depends very much on our contributors' free time. Nevertheless we are ambitious enough to provide reliable versioning and maintenance. Our "always usable" trunk policy helps most of our users to get the newest "goodies" right away from the repository.
We like Mono's versioning policy and our policy follows it:
MAJOR.MINOR.SVNREV
where SVNREV is the svn revision number for that version.
Subproject under SolidOpt's umbrella should follow the same versioning policy unless stated otherwise.
The planned date for releasing is 31.11.2013. Stay tuned!
