Look, it's simple:
3.0 is not really 3.0, but it should be considered 3.0-developer-alpha-gold.
The next release will be 3.2-beta-silver-GTi, followed quickly by 188.8.131.52-gold-gold-always-believe-in-your-soul, which may (or may not) be ready for end users.
Provided no show-stopper bugs are found in that (& if they are they'll just be re-classified as "WORKSFORME" and the submitter flamed), the final 184.108.40.206 version will be released to end users (apart from those in Arizona and Ohio. They have to wait for 3.1.5).
