Normal 3.3 bugfixes are not done until 3.4.0 (final) is released. There 
will be a 3.3.4 at that time.

Yes. 3.3 patches are merged forward unless not applicable.

After normal maintenance ends, code-only, security-fix-only releases of 
x.y continue after that until 5 years after x.y.0.  3.3.0 was released 
2012 Feb so security releases will continue until about 2017 Feb.

The initial 2.6 release was about 2008 Sept, I believe, so this is 5 
years later.

Yes. Core developers will be very happy when normal maintenance of 2.7 ends.

2.7, released about 2010 July, is a special case. It is already past the 
normal maintenance period of 2 years and will get occasional releases 
until 2015. Security fixes after that are not decided.
