Release Date: 2019-01-25

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.
