4.9.1 (2022-07-01)

Bugs fixed

• A crash was resolved when using iterwalk() (or canonicalize()) after parsing certain incorrect input. Note that iterwalk() can crash on valid input parsed with the same parser after failing to parse the incorrect input.

4.9.0 (2022-06-01)

Bugs fixed

• GH#341: The mixin inheritance order in lxml.html was corrected. Patch by xmo-odoo.

Other changes

• Built with Cython 0.29.30 to adapt to changes in Python 3.11 and 3.12.

• Wheels include zlib 1.2.12, libxml2 2.9.14 and libxslt 1.1.35 (libxml2 2.9.12+ and libxslt 1.1.34 on Windows).

• GH#343: Windows-AArch64 build support in Visual Studio. Patch by Steve Dower.

4.8.0 (2022-02-17)

Features added

• GH#337: Path-like objects are now supported throughout the API instead of just strings. Patch by Henning Janssen.

• The ElementMaker now supports QName values as tags, which always override the default namespace of the factory.

Bugs fixed

• GH#338: In lxml.objectify, the XSI float annotation "nan" and "inf" were spelled in lower case, whereas XML Schema datatypes define them as "NaN" and "INF" respectively.

3.7.4 (2021-02-25)

Bugfixes

• (SECURITY BUG) Started preventing open redirects in the aiohttp.web.normalize_path_middleware middleware. For more details, see https://github.com/aio-libs/aiohttp/security/advisories/GHSA-v6wp-4m6f-gcjg.

  Thanks to Beast Glatisant <https://github.com/g147>__ for finding the first instance of this issue and Jelmer Vernooij <https://jelmer.uk/>__ for reporting and tracking it down in aiohttp. [#5497](https://github.com/aio-libs/aiohttp/issues/5497) <https://github.com/aio-libs/aiohttp/issues/5497>_

• Fix interpretation difference of the pure-Python and the Cython-based HTTP parsers construct a yarl.URL object for HTTP request-target.

  Before this fix, the Python parser would turn the URI's absolute-path for //some-path into / while the Cython code preserved it as //some-path. Now, both do the latter. [#5498](https://github.com/aio-libs/aiohttp/issues/5498) <https://github.com/aio-libs/aiohttp/issues/5498>_
