Thanks to Oleh + Prypin for the report and Pierce Lopez for the fix. +* :bug:`990` The (added in 2.2.0) ``bcrypt`` dependency should have been on + version 3.1.3 or greater (was initially set to 3.0.0 or greater.)

This fixes a common case where an ECDSA key is in known_hosts and the + server also has an RSA host key. Thanks to Pierce Lopez. +* :support:`906 (1.18+)` Clean up a handful of outdated imports and related + tweaks. Thanks to Pierce Lopez. +* :bug:`984` Enhance default cipher preference order such that + ``aes(192|256)-cbc`` are preferred over ``blowfish-cbc``. Thanks to Alex + Gaynor. +* :bug:`971 (1.17+)` Allow any type implementing the buffer API to be used with + `BufferedFile <paramiko.file.BufferedFile>`, `Channel + <paramiko.channel.Channel>`, and `SFTPFile <paramiko.sftp_file.SFTPFile>`. + This resolves a regression introduced in 1.13 with the Python 3 porting + changes, when using types such as ``memoryview``. Credit: Martin Packman. +* :bug:`741` (also :issue:`809`, :issue:`772`; all via :issue:`912`) Writing + encrypted/password-protected private key files was silently broken since 2.0 + due to an incorrect API call; this has been fixed. + + Includes a directly related fix, namely adding the ability to read + ``AES-256-CBC`` ciphered private keys (which is now what we tend to write out + as it is Cryptography's default private key cipher.) + + Thanks to ``@virlos`` for the original report, Chris Harris and ``@ibuler`` + for initial draft PRs, and ``@jhgorrell`` for the final patch. +* :feature:`65` (via :issue:`471`) Add support for OpenSSH's SFTP + ``posix-rename`` protocol extension (section 3.3 of `OpenSSH's protocol + extension document + <http://cvsweb.openbsd.org/cgi-bin/cvsweb/src/usr.bin/ssh/PROTOCOL?rev=1.31>`_), + via a new ``posix_rename`` method in `SFTPClient + <paramiko.sftp_client.SFTPClient.posix_rename>` and `SFTPServerInterface + <paramiko.sftp_si.SFTPServerInterface.posix_rename>`. Thanks to Wren Turkal + for the initial patch & Mika Pflüger for the enhanced, merged PR. +* :feature:`869` Add an ``auth_timeout`` kwarg to `SSHClient.connect + <paramiko.client.SSHClient.connect>` (default: 30s) to avoid hangs when the + remote end becomes unresponsive during the authentication step. Credit to + ``@timsavage``. + + .. note:: + This technically changes behavior, insofar as very slow auth steps >30s + will now cause timeout exceptions instead of completing. We doubt most + users will notice; those affected can simply give a higher value to + ``auth_timeout``. + +* :support:`921` Tighten up the ``__hash__`` implementation for various key + classes; less code is good code. Thanks to Francisco Couzo for the patch. +* :support:`956 backported (1.17+)` Switch code coverage service from + coveralls.io to codecov.io (& then disable the latter's auto-comments.) + Thanks to Nikolai Røed Kristiansen for the patch. +* :bug:`983` Move ``sha1`` above the now-arguably-broken ``md5`` in the list of + preferred MAC algorithms, as an incremental security improvement for users + whose target systems offer both. Credit: Pierce Lopez. +* :bug:`667` The RC4/arcfour family of ciphers has been broken since version + 2.0; but since the algorithm is now known to be completely insecure, we are + opting to remove support outright instead of fixing it. Thanks to Alex Gaynor + for catch & patch. +* :feature:`857` Allow `SSHClient.set_missing_host_key_policy + <paramiko.client.SSHClient.set_missing_host_key_policy>` to accept policy + classes _or_ instances, instead of only instances, thus fixing a + long-standing gotcha for unaware users. +* :feature:`951` Add support for ECDH key exchange (kex), specifically the + algorithms ``ecdh-sha2-nistp256``, ``ecdh-sha2-nistp384``, and + ``ecdh-sha2-nistp521``. They now come before the older ``diffie-hellman-*`` + family of kex algorithms in the preferred-kex list. Thanks to Shashank + Veerapaneni for the patch & Pierce Lopez for a follow-up. +* :support:`- backported` A big formatting pass to clean up an enormous number + of invalid Sphinx reference links, discovered by switching to a modern, + rigorous nitpicking doc-building mode. +* :bug:`900` (via :issue:`911`) Prefer newer ``ecdsa-sha2-nistp`` keys over RSA + and DSA keys during host key selection. This improves compatibility with + OpenSSH, both in terms of general behavior, and also re: ability to properly + leverage OpenSSH-modified ``known_hosts`` files. Credit: ``@kasdoe`` for + original report/PR and Pierce Lopez for the second draft. +* :bug:`794` (via :issue:`981`) Prior support for ``ecdsa-sha2-nistp(384|521)`` + algorithms didn't fully extend to covering host keys, preventing connection + to hosts which only offer these key types and no others. This is now fixed. + Thanks to ``@ncoult`` and ``@kasdoe`` for reports and Pierce Lopez for the + patch. * :feature:`325` (via :issue:`972`) Add Ed25519 support, for both host keys and user authentication. Big thanks to Alex Gaynor for the patch. + + .. note:: + This change adds the ``bcrypt`` and ``pynacl`` Python libraries as + dependencies. No C-level dependencies beyond those previously required (for + Cryptography) have been added. + * :support:`974 backported` Overhaul the codebase to be PEP-8, etc, compliant (i.e. passes the maintainer's preferred `flake8 <http://flake8.pycqa.org/>`_ configuration) and add a ``flake8`` step to the Travis config.
