Sage 3.1.2 Release Tour
Notebook Bugs
- Many bugs introduced in 3.1.1 where fixed by Mike Hansen and Timothy Clemans.
- A new testing procedure was implemented hopefully preventing regressions like in 3.1.1. in the future
Improved Dense Linear Algebra over GF(2)
M4RI (http://m4ri.sagemath.org) was updated to the newest upstream release which
- provides much improved performance for multiplication
- provides improved performance for elimination
- contains several build and bugfixes
- hashs and matrix pickling was much improved
dense matrices over \mathbb{F}_2 can now be written to/read from 1-bit PNG images
Doctest Coverage Hits 60%
- Mike Hansen wrote doctests for almost all pexpect interfaces which will ensure greater stability across the board.
New PolyBoRi Version (0.5) and Improved Interface
PolyBoRi was upgraded from 0.3 to 0.5rc
mq.SR now returns PolyBoRi equation systems if asked to
- support for boolean polynomial interpolation was added
QEPCAD Interface
Developer's Handbook
- John H Palmieri rewrote/rearranged large parts of the 'Programming Guide' (now 'Developer's Guide') which should make getting started easier for new developers.
Improved 64-bit OSX Support
Fast Numerical Integration
GAP Meataxe Interface
Better SymPy Integration
Hidden Markov Models
Faster Determinants of Matrices over Multivariate Polynomial Rings
