02 Feb '10

Leo 4.7 beta 3 February 2, 2009 Leo 4.7 beta 3 is now available at: http://sourceforge.net/project/showfiles.php?group_id=3458&package_id=29106 Leo 4.7 beta 3 fixes all known serious bugs in Leo. Leo is a text editor, data organizer, project manager and much more. See: http://webpages.charter.net/edreamleo/intro.html The highlights of Leo 4.7: -------------------------- - Leo now uses the simplest possible internal data model. This is the so-called "one-node" world. - Leo supports Python 3.x. - Leo requires Python 2.6 or above. - Several important improvements in file handling. - Leo converts @file nodes to @thin nodes automatically. - @auto-rst now works much more reliably reliably. - Leo no longer @noref trees. Such trees are not reliable in cooperative environments. - A new Windows installer. - Many other features, including new command line options and new plugins. - Dozens of bug fixes. Edward K.

Cython 0.12.1 released
by Robert Bradshaw 02 Feb '10

02 Feb '10

I'm happy to announce the release of Cython 0.12.1. == About == Cython is a language that makes writing C extensions for the Python language as easy as Python itself. Cython is based on the well-known Pyrex, but supports more cutting edge functionality and optimizations.Cython is an ideal language for wrapping external C libraries, and for fast C modules that speed up the execution of Python code. For more information, see http://cython.org. == Where to get it == http://cython.org http://pypi.python.org/pypi/Cython == New Features == * Type inference improvements. There have been several bug fixes and improvements to the type inferencer. Notably, there is now a "safe" mode enabled by setting the infer_types directive to None. (The None here refers to the "default" mode, which will be the default in 0.13.) This safe mode limits inference to Python object types and C doubles, which should speed up execution without affecting any semantics such as integer overflow behavior like infer_types=True might. There is also an infer_types.verbose option which allows one to see what types are inferred. * The boundscheck directive works for lists and tuples as well as buffers. * len(s) and s.decode("encoding") are efficiently supported for char* s. * Cython's INLINE macro has been renamed to CYTHON_INLINE to reduce conflict and has better support for the MSVC compiler on Windows. It is no longer clobbered if externally defined. * Revision history is now omitted from the source package, resulting in a 85% size reduction. Running make repo will download the history and turn the directory into a complete Mercurial working repository. * Cython modules don't need to be recompiled when the size of an external type grows. (A warning, rather than an error, is produced.) This should be helpful for binary distributions relying on NumPy. Several other bugs and minor improvements have been made. This release should be fully backwards compatible with 0.12. For a list of tickets closed, see http://trac.cython.org/cython_trac/query?group=component&milestone=0.12.1 == Contributors to this release == * Arfrever Frehtes Taifersar Arahesis * Stefan Behnel * Robert Bradshaw * Lisandro Dalcin * Julien Danjou * Mark Lodato * Dag Sverre Seljebotn Thanks also to the many who've submitted feedback and contributed to discussions on the mailing list.

by casevh 02 Feb '10

02 Feb '10

Everyone, I'm pleased to annouce the final release of GMPY 1.11. GMPY is a wrapper for the MPIR or GMP multiple-precision arithmetic library. GMPY 1.11 is available for download from: http://code.google.com/p/gmpy/ In addition to support for Python 3.x, there are several new features in this release: - Even faster conversion to/from Python longs. - Performance improvements by reducing function overhead. - Performance improvements by improved caching. - Support for cdivmod, fdivmod, and tdivmod. - Unicode strings are accepted on Python 2.x and 3.x. - Fixed regression in GMPY 1.10 where True/False were no longer recognized. Changes since 1.11rc1: - Recognizes GMP 5. - Bugs fixed in Windows binaries (MPIR 1.3.0rc3 -> 1.3.1). Comments on provided binaries The 32-bit Windows installers were compiled with MinGW32 using MPIR 1.3.1 and will automatically recognize the CPU type and use code optimized for the CPU at runtime. The 64-bit Windows installers were compiled Microsoft's SDK compilers using MPRI 1.3.1. Detailed instructions are included if you want to compile your own binary. Please report any issues! casevh
