525faaeffc Issue #25262. Added support for BINBYTES8 opcode in Python implementation of 
unpickler.  Highest 32 bits of 64-bit size for BINUNICODE8 and BINBYTES8
opcodes no longer silently ignored on 32-bit platforms in C implementation.

d5d818d40b Issue #18473: Fixed 2to3 and 3to2 compatible pickle mappings. 
Fixed ambigious reverse mappings.  Added many new mappings.  Import mapping
is no longer applied to modules already mapped with full name mapping.

Added tests for compatible pickling and unpickling and for consistency of
_compat_pickle mappings.

d05c9ff845 Issue #6784: Strings from Python 2 can now be unpickled as bytes objects. 
Initial patch by Merlijn van Deen.

I've added a few unrelated docstring fixes in the patch while I was at
it, which makes the documentation for pickle a bit more consistent.

b6a2f2a0d1 Make framing optional in pickle protocol 4. 
This will allow us to control in the future whether to use framing or not.
For example, we may want to turn it off for tiny pickle where it doesn't
help.

The change also improves performance slightly:
