### Release Notes

<details>
<summary>lxml/lxml (lxml)</summary>

### [`v5.2.1`](https://togithub.com/lxml/lxml/blob/HEAD/CHANGES.txt#521-2024-04-02)

[Compare Source](https://togithub.com/lxml/lxml/compare/lxml-5.2.0...lxml-5.2.1)

\==================

## Bugs fixed

-   [LP#2059910](https://togithub.com/LP/lxml/issues/2059910): The minimum CPU architecture for the Linux x86 binary wheels was set back to
    "core2", but with SSE 4.2 enabled.

-   [LP#2059977](https://togithub.com/LP/lxml/issues/2059977): `Element.iterfind("//absolute_path")` failed with a `SyntaxError`
    where it should have issued a warning.

-   [GH#416](https://togithub.com/GH/lxml/issues/416): The documentation build was using the non-standard `which` command.
    Patch by Michał Górny.

### [`v5.2.0`](https://togithub.com/lxml/lxml/blob/HEAD/CHANGES.txt#520-2024-03-30)

[Compare Source](https://togithub.com/lxml/lxml/compare/lxml-5.1.1...lxml-5.2.0)

\==================

## Other changes

-   [LP#1958539](https://togithub.com/LP/lxml/issues/1958539): The `lxml.html.clean` implementation suffered from several (only if used)
    security issues in the past and was now extracted into a separate library:

    https://togithub.com/fedora-python/lxml_html_clean

    Projects that use lxml without "lxml.html.clean" will not notice any difference,
    except that they won't have potentially vulnerable code installed.
    The module is available as an "extra" setuptools dependency "lxml\[html_clean]",
    so that Projects that need "lxml.html.clean" will need to switch their requirements
    from "lxml" to "lxml\[html_clean]", or install the new library themselves.

-   The minimum CPU architecture for the Linux x86 binary wheels was upgraded to
    "sandybridge" (launched 2011), and glibc 2.28 / gcc 12 (manylinux\_2\_28) wheels were added.

-   Built with Cython 3.0.10.

### [`v5.1.1`](https://togithub.com/lxml/lxml/blob/HEAD/CHANGES.txt#511-2024-03-28)

[Compare Source](https://togithub.com/lxml/lxml/compare/lxml-5.1.0...lxml-5.1.1)

\==================

## Bugs fixed

-   [LP#2048920](https://togithub.com/LP/lxml/issues/2048920): `iterlinks()` in `lxml.html` rejected `bytes` input in 5.1.0.

-   High source line numbers from the parser are no longer truncated
    (up to a C `long`) when using libxml2 2.11 or later.

## Other changes

-   [GH#407](https://togithub.com/GH/lxml/issues/407): A compatibility test was adapted to recent expat versions.
    Patch by Miro Hrončok.

-   Binary wheels use the library versions libxml2 2.12.6 and libxslt 1.1.39.

-   Windows binary wheels use the library versions libxml2 2.11.7 and libxslt 1.1.39.

-   Built with Cython 3.0.9.

### [`v5.1.0`](https://togithub.com/lxml/lxml/blob/HEAD/CHANGES.txt#510-2024-01-05)

[Compare Source](https://togithub.com/lxml/lxml/compare/lxml-5.0.2...lxml-5.1.0)

\==================

## Features added

-   Parsing ASCII strings is slightly faster.

## Bugs fixed

-   [GH#349](https://togithub.com/GH/lxml/issues/349): The HTML `Cleaner()` interpreted an accidentally provided string parameter
    for the `host_whitelist` as list of characters and silently failed to reject any hosts.
    Passing a non-collection is now rejected.

## Other changes

-   Support for Python 2.7 and Python versions < 3.6 was removed.

-   The wheel build was migrated to use `cibuildwheel`.
    Patch by Primož Godec.
