Some highlights: defined by Python now have a "Py" or "_Py" prefix, and the same is true for most macros and typedefs. -If you were an alpha tester, here are the most relevant changes since -1.5a4 (of course all known bugs have been fixed, leaks plugged, and -some documentation has been added).

The full list of changes +since 1.5b1 is presented at the end of the Misc/NEWS file. + + - Thanks to all who contributed doc strings for library modules! + + - The portability problems caused by indented preprocessor commands + and C++ style comments should be gone now. + + - Lots of improvements to python-mode.el again. - - Package directories now *require* the presence of __init__.py (or - .pyc/.pyo as applicable). Packages can now contain shared - library modules. + - Changes in pickle.py and cPickle.c: when unpickling an instance of + a class that doesn't define the __getinitargs__() method, the + __init__() constructor is no longer called. This makes a much + larger group of classes picklable by default, but may occasionally + change semantics. To force calling __init__() on unpickling, define + a __getinitargs__() method. Other changes too, in particular + cPickle now handles classes defined in packages correctly. The + same change applies to copying instances with copy.py. - - New module 'fileinput' to iterate over the lines of a list of files. + - Locale support in the "re" (Perl regular expressions) module. Use + the flag re.L (or re.LOCALE) to enable locale-specific matching + rules for \w and \b. The in-line syntax for this flag is (?L). - - New module 'locale' for localized number formatting and string case - sensitivity. + - The built-in function isinstance(x, y) now also succeeds when y is + a type object and type(x) is y. - - New module 'xmllib' to parse XML files. + - repr() and str() of class and instance objects now reflect the + package/module in which the class is defined. - - Some more support for Tk extensions (PIL, TIX, BLT, TOGL). + - Module "ni" has been removed. (If you really need it, it's been + renamed to "ni1". Let me know if this causes any problems for you. + Package authors are encouraged to write __init__.py files that + support both ni and 1.5 package support, so the same version can be + used with Python 1.4 as well as 1.5.) - - Fixed address list parsing in module 'rfc822'. + - The thread module is now automatically included when threads are + configured. (You must remove it from your existing Setup file, + since it is now in its own Setup.thread file.) - - More deployment (and only one fix) for the 're' module. + - New command line option "-x" to skip the first line of the script; + handy to make executable scripts on non-Unix platforms. - - New Python mode for Emacs. + - In importdl.c, add the RTLD_GLOBAL to the dlopen() flags. I + haven't checked how this affects things, but it should make symbols + in one shared library available to the next one. - - OS/2 support. + - The Windows configuration adds a new main program, "pythonw", and + registers a new extension, ".pyw" that invokes this. This is a + standard Python interpreter that does not pop up a console window; + handy for pure Tkinter applications. All output to the original + stdout and stderr is lost; reading from the original stdin yields + EOF. If you don't read instructions |
