* Added support for the Counter Mode KDF defined in SP 800-108 Rev 1.
* Reduce the minimum tag length for the EAX cipher to 2 bytes.
* An RSA object has 4 new properties for the CRT coefficients: ``dp``, ``dq``, ``invq`` and ``invq`` (``invp`` is the same value as the existing ``u``).
* GH#526: improved typing for ``RSA.construct``.
* GH#534: reduced memory consumption when using a large number of cipher objects.
* GH#598: fixed missing error handling for ``Util.number.inverse``.

* Import and export of ECC curves in compressed form.
* The initial counter for a cipher in CTR mode can be a byte string (in addition to an integer).

* More meaningful error messages while importing an ECC key. - Resolved issues
* GH#123 and #125. The SSE2 command line switch was not always passed on 32-bit x86 platforms.

* Added a native extension in pure C for modular exponentiation, optimized for SSE2 on x86. In the process, we drop support for the arbitrary arithmetic library MPIR on Windows, which is painful to compile and deploy. The custom modular exponentiation is 130% (160%) slower on an Intel CPU in 32-bit (64-bit) mode, compared to MPIR. Still, that is much faster that CPython\'s own `pow()` function which is 900% (855%) slower than MPIR. Support for the GMP library on Unix remains.
* Added support for
*manylinux
* wheels.
* Support for Python 3.7. - Resolved issues
