Log Message:
py-msgpack: updated to 1.0.0

1.0.0

Remove Python 2 support from the msgpack/_cmsgpack. msgpack/fallback still \ 
supports Python 2.
Remove encoding option from the Packer and Unpacker.
Unpacker: The default value of max_buffer_type is changed to 100MiB.
Unpacker: strict_map_key is True by default now.
Unpacker: String map keys are interned.
Drop old buffer protocol support.
Support Timestamp type.
Support serializing and decerializing datetime object with tzinfo.
Unpacker: Fix Unpacker.read_bytes() in fallback implementation.

0.6.2

Support Python 3.8.
Update Cython to 0.29.13 for support Python 3.8.
Some small optimizations.

0.6.1

This release is for mitigating pain caused by v0.6.0 reduced max input limits \ 
for security reason.

unpackb(data) configures max_*_len options from len(data), instead of static \ 
default sizes.
Unpacker(max_buffer_len=N) configures max_*_len options from N, instead of \ 
static default sizes.
max_bin_len, max_str_len, and max_ext_len are deprecated. Since this is minor \ 
release, it's document only deprecation.

0.6.0

This release contains some backward incompatible changes for security reason (DoS).

Important changes

unpacker: Default value of input limits are smaller than before to avoid DoS \ 
attack. If you need to handle large data, you need to specify limits manually.
Unpacker doesn't wrap underlaying ValueError (including UnicodeError) into \ 
UnpackValueError. If you want to catch all exception during unpack, you need to \ 
use try ... except Exception with minimum try code block.
PackValueError and PackOverflowError are also removed. You need to catch normal \ 
ValueError and OverflowError.
Unpacker has strict_map_key option now. When it is true, only bytes and str \ 
(unicode in Python 2) are allowed for map keys. It is recommended to avoid \ 
hashdos. Default value of this option is False for backward compatibility \ 
reason. But it will be changed True in 1.0.

Other changes

Extension modules are merged. There is msgpack._cmsgpack instead of \ 
msgpack._packer and msgpack._unpacker.
Add Unpacker.getbuffer() method.
unpacker: msgpack.StackError is raised when input data contains too nested data.
unpacker: msgpack.FormatError is raised when input data is not valid msgpack format.
