-compiler core is now 10% smaller (from 7700 to under 7000 lines)
-weird templates would confuse user
-traditional important TI fixes (disappearing types, non-termination) -compiler should use about 25% less memory and CPU time -huge refactoring for readability in infer.py and cpp.py -extmod fixes: -incref None, so it doesn't get deallocated
-accept None when converting to custom class instance
-new command-line option -r, for faster random number generator (C rand()) -bounds checking is now on by default (for compatibility), -b now turns it off -many minor bug fixes/improvements -added os.SEEK*
-added file.next

- support for frozenset
- improved compiler flags under OSX
- important type inference fix (disappearing type) - improved variable overloading - casting improvements - fixes for setslice, delslice corner cases - xrange returns xrange object instead of iterator - several other bugfixes Shed Skin 0.0.30- user-defined class support in extension modules - blindingly fast set implementation (FFAO) - complex number support - many string formatting improvements - None maps to NULL instead of 0, and prints as 'None' - re.match_object.group accepts multiple arguments - casting improvements - inheritance from builtin exceptions other than Exception - hashing None should work now - important type inference fix - many, many bugfixes Shed Skin 0.0.29- datetime implementation (Karel Heyse, Pavel Vinogradov, FFAO, David Marek) - ConfigParser implementation (suggested by Albert Hofkamp) - staticmethod and property decorator support (Seo Sanghyeon) - GCC 4.3 fixes (Seo Sanghyeon, Winterknight) - FreeBSD, OpenSolaris and 64-bit support - support for mapping keys('%(key)x' % some_dict) - improvements to the import mechanism for nested modules (e.g. os.path) - __init__ is now less of a special case - many fixes for calling ancestor methods (e.g. __init__) - all example programs now compile to extension modules - avoid stack overflows for highly recursive/dynamic types - re.sub now accepts a replacement function - remove tuple hash caching (as CPython does not do this) - many, many bugfixes Shed Skin 0.0.28- basic 'socket' support (Michael Elkins) - support for os.{popen3, popen4} (Jaroslaw Tworek) - support for time.strptime under Windows (David Marek) - options for changing output dir, disabling annotation (Dave Tweed) - support for 'cmp' and 'reverse' arguments of 'sorted' and 'list.sort' - fixes for cross-module default arguments - important fixes for type inference and inheritance - restore compatibility with Python 2.3 - many minor bugfixes Shed Skin 0.0.27- support for 're', via libpcre (perl-compatible-regular-expressions) - support for 'time' (except for time.strptime under Windows) - basic support for 'staticmethod' and 'property' - support for 'fnmatch', 'glob' (bootstrapped) - improved support for 'os' (POSIX) - OSX support (including extension modules!) - many fixes for multi-dir/multi-file projects - several builtin optimizations (zip, list(str)..) - type model for 'datetime' (no C++ implementation yet) - split up compiler core, ss.py, into several files - many minor bugfixes Shed Skin 0.0.26-support for: -most os.path methods

Excellent work! I will be following the next releases. I am working on an ASCII Render Engine, based on Numpy and Python-Imaging. ASCII texts with 1600x1200 letters take quite a long time to render, 3-4 seconds was the best i could get... I need to get 30 per second, so i need to speed up 100 times. Maybe Shed Skin will be able to work with Numpy and Python-Imaging in the future.
shedskin is cool!
This is a great project. Please continue your dedicated work on this. I am using shedskin generated modules in production code - it works wonderfully!
@prah: have you considered using shedskin to generate an extension module? shedskin will probably never work directly with other modules than the most common ones in the standard library.
@freeall: I think so too, too bad I don't get much help!!
@abe: good to hear shedskin is useful for you.. please do let me know about any problems, even if you are able to work around them.
Is shedskin able to import custom .pyd file in windows?
no, shedskin needs .py files to do its type inference. what you might do, is generate another .pyd file with shedskin, and import both .pyd files in a regular python program. would that work?
