No detailed change log; just check out the change log for the py3k-pep3137
branch. The most obvious changes:
- str8 renamed to bytes (PyString at the C level);
- bytes renamed to buffer (PyBytes at the C level);
- PyString and PyUnicode are no longer compatible.
I.e. we now have an immutable bytes type and a mutable bytes type.
The behavior of PyString was modified quite a bit, to make it more
bytes-like. Some changes are still on the to-do list.
Add a bytes iterator (copied from stringobject.c and reindented :-).
I (Guido) added a small change to _abcoll.py to remove the registration
of bytes as a virtual subtype of Iterator -- the presence of __iter__
will handle that now.
Additional patch by Christian Heimes to deal more cleanly with the
FILE* vs file-descriptor issues.
I cleaned up his code a bit, and moved the lseek() call into import.c.
to be called a buffer). Shares code with stringobject when possible.
Adds unit tests with common code that should be usable to test the PEPs
mutable buffer() and immutable bytes() types.

Support bytes.split() and bytes.strip() -- these split/strip using ASCII
whitespace (tab, space, CR, LF, FF, VT) like their str counterparts.
Also for rsplit(), lstrip() and rstrip().
And change all these functions to accept arbitrary buffer-API-supporting
arguments.
With unit tests.
From now on, trying to write str to a binary stream
is an error (I'm still working on the reverse).
There are still (at least) two failing tests:
- test_asynchat
- test_urllib2_localnet
but I'm sure these will be fixed by someone.
be answered with the comments removed.
There are many places that require checks when doing arithmetic for memory
sizes when allocating memory. Otherwise, overflow is possible with
a subsequent crash.
Fix SF #1777057 which was a result of not initializing the new BufferError
properly. Had to update the test for exceptions for BufferError too.
strings, in Latin-1. Bytes are once more pickled through bytes.__reduce__,
but now it returns "latin-1" as the second parameter.
Unfortunately this breaks datetime pickling. I'll have to investigate
further; reverting Martin's changes doesn't seem to help.
's' and 'c' codes.
Change pickle to dump bytes objects using the 'S'
code, and to load the 'S' code as byte objects.
Change datetime and array to generate and expect
bytes objects in reduce/unreduce.
