See NEWS (in the Misc folder) -for machine-independent changes. +for machine-independent changes. But note that more things may have changed: MacPython +2.2a2 is built from newer sources than unix/windows 2.2a2 (for CVS users: the r22a2-mac +tag is what you are looking for). -- Handling non-ascii characters in sys.path on non-MacRoman systems should be fixed, - iff MacPython has a codec for the charset. Otherwise you should get an error, at least. - Pathnames in sys.path also retain their original case again. -- IDE could crash on corrupt preferences. Fixed. -- IDE will now work if you use either pre or sre as re. -- Evt.WaitNextEvent could give an error when bit 15 was set, which could cause a problem - with IDE in classic mode. Fixed. -- MacOS8.X users in classic mode had problems with Fm not loading, which also caused - IDE not working. Fixed. -- Fm.IsAntiAliasedTextEnabled and Fm.SetAntiAliasedTextEnabled have gone for now, to - fix the problem above. -- Disabled the Tkinter file I/O event handler, which was there but didn't work anyway. -- Problems with loading dynamic modules that are part of a package into BuildApplication- - generated programs were fixed. -- The order of the EasyDialogs yes/no/cancel buttons has been conformed to the Mac - standard. -- Handling of Dialogs and Windows that were not created by Python is a bit more graceful - now, which may fix some crashes. -- Ctl.SendControlMessage has gone. But it didn't work anyway. -- Various problems with the TextEdit and Waste demos have been fixed. -- Embedding/extending only: in preparation to allowing the use of MacPython modules in - unix-Python on OSX the xxx_New and xxx_Convert routines are now optionally vectored via - glue routines in macglue.c. The only change that may be needed for embedders/extenders is - that you may want to include pymactoolbox.h in your sources. -- Embedding/extending only: Most MacPython source is now much more Mach-O friendly, and - should work with Universal Headers 3.4. -- Experimental: an Mlte module has been added, an interface to the Multi Lingual Text - Engine. There is a minimal example in :Mac:Demos:mlte. -- Experimental: some support for FSRef objects has been added. You can do little more that - convert them to/from FSSpecs. Carbon only. -- Experimental: the CF module has some support for CoreFoundation types. CFString - and CFURL work, to a degree, and can be converted to/from Python strings and Unicode - objects. Carbon only. +- The main change is that all toolbox modules have moved to a package called Carbon. + So things like "import Res" should be changed to "from Carbon import Res", and + "from Res import *" to "from Carbon.Res import *". Please see the readme file for + some open questions and join the discussions on pythonmac-sig if you have anything + to contribute. Aside from reducing clutter this change will also benefit the + port to Mach-O/OSX Python later. +- On input MacPython now accepts either \n (unix style) or \r (mac style) newlines + for text files. This is an experimental feature; again: feedback is requested. +- There is a new module macresource which makes it easier to open a resource file + accompanying your script when the script is not (yet) converted to an applet. + This module will later also do the right thing in Mach-O/OSX Python. +- Threads had a stack that was too small for many serious Python applications (20K). + They now get 64K. There is still no overflow check, though. +- Garbage collection and the gc module have (finally) been enabled. +- EasyDialogs.ProgressBar now has indeterminate progressbars if you specify maxval=0. + This is also the new default. Patch supplied by Dean Draayer. +- Various outdated scripts have been moved to :Mac:Unsupported. +- Various outdated items from :Mac:Lib:test have been removed. What is not in this distribution -------------------------------- -- The garbage collection mods have not been enabled, mainly due to lack of test-time. -- Stackless Python/microthreads hasn't been ported to 2.1 yet. If/when it becomes available +- Stackless Python/microthreads hasn't been ported to 2.2 yet. If/when it becomes available Just will undoubtedly announce it on pythonmac-sig and the MacPython homepage. +- The toolbox modules have not been updated to Universal Header 3.4 or CarbonLib 1.4 yet.
