Hello folks,
this release is overdue, but here we go. We have loads of little
fixes, but also
* massive improvements to number fields (Francis Clarke)
* Cython 0.11 (upstream Cython team including Robert Bradshaw)
* rewrite fast_float to support more datatypes (Carl Witty)
* much better UTF8/unicode support in the notebook
Apologies to anyone I might have forgotten. Doctesting so far revealed
one new problem:
sage -t "devel/sage/sage/rings/number_field/
number_field_ideal_rel.py"
**********************************************************************
File "/space/wstein/farm/sage-3.4.1.alpha0/devel/sage/sage/rings/
number_field/number_field_ideal_rel.py", line 598:
sage: z = I.element_1_mod(J); z
Expected:
-8*b*a + 24
Got:
-21/2*b*a - 21/2
**********************************************************************
This issue is already in trac and has a patch that is part of a larger
patch.
Aside from the doctests failure that will pop up here is the plan for
3.4.1:
* downgrade GAP to 4.4.10 due to problems on Itanium
* upgrade to MPIR 1.0
* Merge the Brandt module patch at #5520
* SSE2 only support for ATLAS build
Sources as well as a sage.math only binary can be found in
http://sage.math.washington.edu/home/mabshoff/release-cycles-3.4.1/
Please build, test and report any issues.
Cheers,
Michael
