Release notes
*Sourced from [ecdsa's releases](https://github.com/warner/python-ecdsa/releases).*
> ## ecdsa 0.13.3
> Fix CVE-2019-14853 - possible DoS caused by malformed signature decoding
> Fix CVE-2019-14859 - signature malleability caused by insufficient checks of DER encoding
>
> Also harden key decoding from string and DER encodings.
>
> ## ecdsa 0.13.2
> Restore compatibility of setup.py with Python 2.6 and 2.7.
>
> ## ecdsa 0.13.1
> Fix the PyPI wheel - the old version included .pyc files.
>
> ## ecdsa 0.13
> Fix the argument order for Curve constructor (put openssl_name= at the end,
> with a default value) to unbreak compatibility with external callers who used
> the 0.11 convention.
>
> ## ecdsa 0.12
> Switch to Versioneer for version-string management (fixing the broken
> `ecdsa.__version__` attribute). Add Curve.openssl_name property. Mention
> secp256k1 in README, test against OpenSSL. Produce "wheel" distributions. Add
> py3.4 and pypy3 compatibility testing. Other minor fixes.
