Release notes for MacPython 1.5.1
1997-10-08 12:35:17 -03:00
---------------------------------
1998-01-06 08:13:16 -04:00
Open Issues and bugs:
1998-04-27 12:14:36 -03:00
- Packages ("dotted import") appears to have problems for the cfm68k
version of MacPython. Please report anything of interest you find as
soon as possible, preferrably to pythonmac-sig@python.org. I no longer
have access to a reasonable 68K machine, so it may well be that this
means the demise of cfm68k Python is near.
- Printing a NumPy "array([1.2])" may cause a crash in
cfm68k-Python. Same comments as above.

Changes since the previous version:
1998-04-27 12:14:36 -03:00
Here are the mac-specific changes since MacPython 1.4, with
end-user-visible changes near the top and API changes and other things
that are developer-only more to the bottom. Changes marked with a [*]
are new changes since 1.5b3 (there has never been a MacPython 1.5
final). And, of course, all Guido's 1.5.1 changes are
incorporated.
1998-04-27 12:14:36 -03:00
- Imported modules are now case-checked: the case of the filename
should match the name under which you import it [*]
- There is now some minimal documentation on building true standalone
applications in Python, see building.html [*]
- Python's private resources now use numbers from 228 up, because of
conflicts with Tk. This may affect you if you include private
resources in applets. [*]
- Audio_mac spike bug fixed. [*]
- FrameWork menu cleanup fixed. [*]
- More MacOS errors now have a (somewhat) symbolic description. [*]
- mactty module added to allow basic access to a serial line. [*]
- toolbox modules have been regenerated, occasionally giving access to
new functionality. They are now based upon Universal Headers version
3.1 [*]
- Waste module now uses Waste 1.3 [*]
- Waste module now exports WE{Get,Set}TabSize [*]
- Ordinal support in aetypes added (by Bill Bedford) [*]
- ColorPicker module added (by Just van Rossum). It isn't documented,
but the docstring should be good enough. [*]
- Printing module added (by Just van Rossum). It isn't documented and
it isn't easy to understand, but with Inside Mac beside you it might
be useable. There's a test script in Mac:Lib:test. [*]
- Sndihooks module added to give access to sound-input. Only lightly
tested and not documented yet. [*]
- fstat() added to mac module. [*]
- double dispose in MacOS.splash() fixed. [*]
- Qt module now supports getting/setting movie times [*]
- BuildApplet now also accepts old applets as input, which are updated
to the current Python version [*]
- Moved Mac:Lib:toolbox and scripting to lib-toolbox and
lib-scripting, analogous to Guido's changes. Initial sys.path settings
reflect this change
- Added cPickle and cStringIO modules
1998-01-06 08:13:16 -04:00
- Balloon help in set-preferences dialog and EditPythonPrefs
- An interface to the Help Maganer has been added
1997-10-10 12:48:57 -03:00
- New modules "preferences" and "pythonprefs" which allow access to
Python preferences and implements a general preference-handling
1998-01-06 08:13:16 -04:00
framework. New EditPythonPrefs uses this.
1997-10-10 12:48:57 -03:00
- Applescript suite modules are now in a separate Mac:Lib:scripting
1998-01-06 08:13:16 -04:00

ConfigurePython
1997-10-08 12:35:17 -03:00

1997-10-10 12:48:57 -03:00
exit
1997-10-08 12:35:17 -03:00
- Influencing command-. and event processing (formerly MacOS.SetYield
1997-10-10 12:48:57 -03:00
and MacOS.SetScheduleTimes) has been changed, see the manual
1997-10-08 12:35:17 -03:00
- FrameWork (or your own windowing code) can use asynchronous
1997-10-10 12:48:57 -03:00
callbacks to keep user interface responsive during long computations
- Module to interface to Internet Config added
- Module calldll added that allows calling of arbitrary C routines
from MacOS toolboxes
- gdbm module added
- ctb error handling fixed, and some memory leaks plugged
- Various of the documentation files in Mac:Demo have been updated

to close themselves.
- Loading of PYC resources from the application greatly speeded up,
especially for CDROM based applications
- interrupt check/eventloop only entered 10 times per second, giving
big speedup

- Twit resource number conflict with debuggee fixed
- sys.path preference can now be longer than 255 chars
- cfmfile module allows parsing and merging of CFRG resources
- PythonFAT and PythonApplet are now fat (PPC/CFM68K) applications, so
applets can be moved between architectures.
- Twit resource number conflict with debuggee fixed

- unshar made a bit more mac-friendly (input output dialogs)
- img: added png, xbm, bmp support

- Project "segment" structure changed to more-or-less follow folder
structure
- fullbuild redesigned
