Hello folks,

4
available at

              http://sagemath.org/download.html

7


8
This is the first release after the excellent Sage Days 6 in Bristol.

9
We are a couple days late, mostly due to a rocky initial alpha0 that

10
took some time to sort out and also the new policy that all patches

11
have to be reviewed before they can get merged.

The usual suspects contributed major pieces to this release:

14


15
 - Bill Hart

16
 - John Cremona

17
 - Josh Kantor

18
 - Martin Albrecht

19
 - Michael Abshoff

27
Sorry if I forgot anybody, it has been quite a turbulent release

28
cycle. Thanks to all the reviewers, all the testers, especially

29
Jaap Spies, and please send me patches for the doctest failures.

Cheers,

* Major Features, New Spkgs and Bugfixes

36


37
Major new features are John Cremona's g0n, updates to flint, scipy &

38
numpy, cvxopt and sympy as well as major bug fixes to libfplll and

39
memory leak fixes in linbox. This is also the first release that

40
compiles on OSX 10.5 "out of the box", i.e. without the need to have

41
gfortran installed.

for details.

63
* Known Issues with 2.8.13

64


65
 - cvxopt fails to import on OSX PPC (ticket #1222)

66
 - g0n, i.e. cremona.spkg fails to compile on Linux/Itanium with

67
  older gcc and also Solaris.

68


69
* Upcoming Releases

70


71
2.8.14 is planned for next week, depending on how close the release

72
will be to Sage Bug Day 6 on December 2nd, 2007 we might do another

73
2.8.15 release the day before. Major spkg candidates for 2.8.14 are

74


75
 - Singular 3-0-4

76
 - PolyBoRi

77
 - ATLAS BLAS/Lapack

78


79
It looks unlikely that we will achieve the major goals for 2.9, namely

80
Solaris 32 bit support and OSX 10.5 64 bit support, in the next two

81
weeks, so we might do a couple more 2.8.x releases.
