Changelogs

asn1crypto 0.22.0 -> 0.23.0

0.23.0

• Backwards compatibility break: the tag_type, explicit_tag and
  explicit_class attributes on core.Asn1Value no longer exist and were
  replaced by the implicit and explicit attributes. Field param dicts
  may use the new explicit and implicit keys, or the old tag_type and
  tag keys. The attribute changes will likely to have little to no impact
  since they were primarily an implementation detail.
• Teletex strings used inside of X.509 certificates are now interpreted
  using Windows-1252 (a superset of ISO-8859-1). This enables compatibility
  with certificates generated by OpenSSL. Strict parsing of Teletex strings
  can be retained by using the x509.strict_teletex() context manager.
• Added support for nested explicit tagging, supporting values that are
  defined with explicit tagging and then added as a field of another
  structure using explicit tagging.
• Fixed a UnicodeDecodeError when trying to find the (optional) dependency
  OpenSSL on Python 2
• Fixed next_update field of crl.TbsCertList to be optional
• Added the x509.Certificate.sha256_fingerprint property
• x509.Certificate.ocsp_urls and x509.DistributionPoint.url will now
  return https://, ldap:// and ldaps:// URLs in addition to http://.
• Added CMS Attribute Protection definitions from RFC 6211
• Added OIDs from RFC 6962

cffi 1.10.0 -> 1.11.0

1.11

=====

• Support the modern standard types char16_t and char32_t.
  These work like wchar_t: they represent one unicode character, or
  when used as charN_t * or charN_t[] they represent a unicode
  string. The difference with wchar_t is that they have a known,
  fixed size. They should work at all places that used to work with
  wchar_t (please report an issue if I missed something). Note
  that with set_source(), you need to make sure that these types are
  actually defined by the C source you provide (if used in cdef()).

• Support the C99 types float _Complex and double _Complex.
  Note that libffi doesn't support them, which means that in the ABI
  mode you still cannot call C functions that take complex numbers
  directly as arguments or return type.

• Fixed a rare race condition when creating multiple FFI instances
  from multiple threads. (Note that you aren't meant to create many
  FFI instances: in inline mode, you should write ffi = cffi.FFI() at module level just after import cffi; and in
  out-of-line mode you don't instantiate FFI explicitly at all.)

• Windows: using callbacks can be messy because the CFFI internal error
  messages show up to stderr---but stderr goes nowhere in many
  applications. This makes it particularly hard to get started with the
  embedding mode. (Once you get started, you can at least use
  ffi.def_extern(onerror=...) and send the error logs where it
  makes sense for your application, or record them in log files, and so
  on.) So what is new in CFFI is that now, on Windows CFFI will try to
  open a non-modal MessageBox (in addition to sending raw messages to
  stderr). The MessageBox is only visible if the process stays alive:
  typically, console applications that crash close immediately, but that
  is also the situation where stderr should be visible anyway.

• Progress on support for callbacks in NetBSD__.

• Functions returning booleans would in some case still return 0 or 1
  instead of False or True. Fixed.

• ffi.gc()__ now takes an optional third parameter, which gives an
  estimate of the size (in bytes) of the object. So far, this is only
  used by PyPy, to make the next GC occur more quickly (issue 320).
  In the future, this might have an effect on CPython too (provided
  the CPython issue 31105 is addressed).

• Add a note to the documentation: the ABI mode gives function objects
  that are slower to call than the API mode does. For some reason it
  is often thought to be faster. It is not!

1.10.1

=======

lxml 3.8.0 -> 4.0.0

4.0.0

==================

Features added

• The ElementPath implementation is now compiled using Cython,
  which speeds up the .find*() methods quite significantly.

• The modules lxml.builder, lxml.html.diff and lxml.html.clean
  are also compiled using Cython in order to speed them up.

• xmlfile() supports async coroutines using async with and await.

• iterwalk() has a new method skip_subtree() that prevents walking into
  the descendants of the current element.

• RelaxNG.from_rnc_string() accepts a base_url argument to
  allow relative resource lookups.

• The XSLT result object has a new method .write_output(file) that serialises
  output data into a file according to the <xsl:output> configuration.

Bugs fixed

• GH251: HTML comments were handled incorrectly by the soupparser.
  Patch by mozbugbox.

• LP1654544: The html5parser no longer passes the useChardet option
  if the input is a Unicode string, unless explicitly requested. When parsing
  files, the default is to enable it when a URL or file path is passed (because
  the file is then opened in binary mode), and to disable it when reading from
  a file(-like) object.

Note: This is a backwards incompatible change of the default configuration.
If your code parses byte strings/streams and depends on character detection,
please pass the option guess_charset=True explicitly, which already worked
in older lxml versions.

• LP1703810: etree.fromstring() failed to parse UTF-32 data with BOM.

• LP1526522: Some RelaxNG errors were not reported in the error log.

• LP1567526: Empty and plain text input raised a TypeError in soupparser.

• LP1710429: Uninitialised variable usage in HTML diff.

• LP1415643: The closing tags context manager in xmlfile() could continue
  to output end tags even after writing failed with an exception.

• LP1465357: xmlfile.write() now accepts and ignores None as input argument.

• Compilation under Py3.7-pre failed due to a modified function signature.

Other changes

• The main module source files were renamed from lxml.*.pyx to plain
  *.pyx (e.g. etree.pyx) to simplify their handling in the build
  process. Care was taken to keep the old header files as fallbacks for
  code that compiles against the public C-API of lxml, but it might still
  be worth validating that third-party code does not notice this change.

pyopenssl 17.2.0 -> 17.3.0

17.3.0

---

Backward-incompatible changes:
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

• Dropped support for Python 3.3.
  677 <https://github.com/pyca/pyopenssl/pull/677>_
• Removed the deprecated OpenSSL.rand module.
  This is being done ahead of our normal deprecation schedule due to its lack of use and the fact that it was becoming a maintenance burden.
  os.urandom() should be used instead.
  675 <https://github.com/pyca/pyopenssl/pull/675>_

Deprecations:
^^^^^^^^^^^^^

• Deprecated OpenSSL.tsafe.
  673 <https://github.com/pyca/pyopenssl/pull/673>_

Changes:
^^^^^^^^

• Fixed a memory leak in OpenSSL.crypto.CRL.
  690 <https://github.com/pyca/pyopenssl/pull/690>_
• Fixed a memory leak when verifying certificates with OpenSSL.crypto.X509StoreContext.
  691 <https://github.com/pyca/pyopenssl/pull/691>_

---

• Pull request 178: with_metaclass now properly proxies __prepare__ to the
  underlying metaclass.

• Pull request 191: Allow with_metaclass to work with metaclasses implemented
  in C.

• Pull request 203: Add parse_http_list and parse_keqv_list to moved
  urllib.request.

• Pull request 172 and issue 171: Add unquote_to_bytes to moved urllib.parse.

• Pull request 167: Add six.moves.getoutput.

• Pull request 80: Add six.moves.urllib_parse.splitvalue.

• Pull request 75: Add six.moves.email_mime_image.

• Pull request 72: Avoid creating reference cycles through tracebacks in
  reraise.

zope.interface 4.4.2 -> 4.4.3

4.4.3

---

• Avoid exceptions when the __annotations__ attribute is added to
  interface definitions with Python 3.x type hints. See issue 98 <https://github.com/zopefoundation/zope.interface/issues/98>_.
• Fix the possibility of a rare crash in the C extension when
  deallocating items. See issue 100 <https://github.com/zopefoundation/zope.interface/issues/100>_.

That's it for now!
