* Bug statistics
We closed 65 tickets. For details see
http://trac.sagemath.org/sage_trac/milestone/sage-4.4.2
or check out the closed ticket section at the end of the announcement.
* Doctesting coverage
For Sage 4.4.1, we had an overall weighted doctest coverage score of
81.7%, with 25,475 functions. In Sage 4.4.2, we increased the doctest
coverage by 0.4% and added 38 new functions. Thus for Sage 4.4.2 we
now have
* Overall weighted coverage score: 82.1%
* Total number of functions: 25,513
* Known issues
On 32-bit systems, there are random segfaults in doctests of
planarity.pyx. This issue is tracked at ticket #8756.
