Versions are year-based with a strict :doc:`backward-compatibility` policy. The third digit is only for regressions.
This is the first release under full stewardship of PyCA. We have made many changes to make local development more pleasing. The test suite now passes both on Linux and OS X with OpenSSL 0.9.8, 1.0.1, and 1.0.2. It has been moved to py.test, all CI test runs are part of tox and the source code has been made fully flake8 compliant.
We hope to have lowered the barrier for contributions significantly but are open to hear about any remaining frustrations.
- Python 3.2 support has been dropped.
It never had significant real world usage and has been dropped by our main dependency
cryptography. Affected users should upgrade to Python 3.3 or later.
The support for EGD has been removed. The only affected function :func:`OpenSSL.rand.egd` now uses :func:`os.urandom` to seed the internal PRNG instead. Please see pyca/cryptography#1636 for more background information on this decision.
Please note that you should use urandom for all your secure random number needs.
In accordance with our backward compatibility policy :func:`OpenSSL.rand.egd` will be removed no sooner than a year from the release of 15.2.0
- Added :func:`OpenSSL.crypto.dump_publickey` to dump :class:`OpenSSL.crypto.PKey` objects that represent public keys, and :func:`OpenSSL.crypto.load_publickey` to load such objects from serialized representations. [#382]
- Added :func:`OpenSSL.crypto.dump_crl` to dump a certificate revocation list out to a string buffer. [#368]
- Added :meth:`OpenSSL.SSL.Connection.state_string` using the OpenSSL binding
state_string_long. [#358] - Added support for the
socket.MSG_PEEKflag to :meth:`OpenSSL.SSL.Connection.recv` and :meth:`OpenSSL.SSL.Connection.recv_into`. [#294] - Added :meth:`OpenSSL.SSL.Connection.get_protocol_version` and :meth:`OpenSSL.SSL.Connection.get_protocol_version_name`. [#244]
- Switched to utf8string mask by default.
OpenSSL formerly defaulted to a T61String if there were UTF-8 characters present.
This was changed to default to UTF8String in the config around 2005, but the actual code didn't change it until late last year.
This will default us to the setting that actually works.
To revert this you can call
OpenSSL.crypto._lib.ASN1_STRING_set_default_mask_asc(b"default"). [#234]
The changes from before release 15.2.0 are preserved in the repository.
