Distro packagers have been consulted and as far as has been answered so
far, the lowest version of Twisted on the distros' platforms is 22.1, so
this bump should be safe.
This gives us 2 notable things:
- contextvar propagation support, which would let us remove A LOT of
logcontext machinery
and vastly simplify logcontext rules!
- The test helpers have moved to the new location, so no longer will you
import test helpers
from the 'correct' (non-deprecated) path and get told by CI (olddeps)
that your test
doesn't exist.
Changelog entries for those are reproduced below:
> - twisted.internet.defer.inlineCallbacks and ensureDeferred will now
associate a contextvars.Context with the coroutines they run, meaning
that ContextVar objects will maintain their value within the same
coroutine, similarly to asyncio Tasks. This functionality requires
Python 3.7+, or the contextvars PyPI backport to be installed for Python
3.5-3.6. (#<!--- -->9719, #<!--- -->9826)
>
> - twisted.test.proto_helpers has moved to twisted.internet.testing.
twisted.test.proto_helpers has been deprecated. (#<!--- -->6435)

Clean up `MetricsResource`, Prometheus hacks
(`_set_prometheus_client_use_created_metrics`), and better document why
we care about having a separate `metrics` listener type.
These clean-up changes have been split out from
https://github.com/element-hq/synapse/pull/18584 since that PR was
closed.

changelog</a>.</em></p>
<blockquote>
<h1>6.0.0 (2025-06-26)</h1>
<h2>Features added</h2>
<ul>
<li>
<p>GH#463: <code>lxml.html.diff</code> is faster and provides
structurally better diffs.
Original patch by Steven Fernandez.</p>
</li>
<li>
<p>GH#405: The factories <code>Element</code> and
<code>ElementTree</code> can now be used in type hints.</p>
</li>
<li>
<p>GH#448: Parsing from <code>memoryview</code> and other buffers is
supported to allow zero-copy parsing.</p>
</li>
<li>
<p>GH#437: <code>lxml.html.builder</code> was missing several HTML5 tag
names.
Patch by Nick Tarleton.</p>
</li>
<li>
<p>GH#458: <code>CDATA</code> can now be written into the incremental
<code>xmlfile()</code> writer.
Original patch by Lane Shaw.</p>
</li>
<li>
<p>A new parser option <code>decompress=False</code> was added that
controls the automatic
input decompression when using libxml2 2.15.0 or later. Disabling this
option
by default will effectively prevent decompression bombs when handling
untrusted
input. Code that depends on automatic decompression must enable this
option.
Note that libxml2 2.15.0 was not released yet, so this option currently
has no
effect but can already be used.</p>
</li>
<li>
<p>The set of compile time / runtime supported libxml2 feature names is
available as
<code>etree.LIBXML_COMPILED_FEATURES</code> and
<code>etree.LIBXML_FEATURES</code>.
This currently includes
<code>catalog</code>, <code>ftp</code>, <code>html</code>,
<code>http</code>, <code>iconv</code>, <code>icu</code>,
<code>lzma</code>, <code>regexp</code>, <code>schematron</code>,
<code>xmlschema</code>, <code>xpath</code>, <code>zlib</code>.</p>
</li>
</ul>
<h2>Bugs fixed</h2>
<ul>
<li>
<p>GH#353: Predicates in <code>.find*()</code> could mishandle tag
indices if a default namespace is provided.
Original patch by Luise K.</p>
</li>
<li>
<p>GH#272: The <code>head</code> and <code>body</code> properties of
<code>lxml.html</code> elements failed if no such element
was found. They now return <code>None</code> instead.
Original patch by FVolral.</p>
</li>
<li>
<p>Tag names provided by code (API, not data) that are longer than
<code>INT_MAX</code>
could be truncated or mishandled in other ways.</p>
</li>
<li>
<p><code>.text_content()</code> on <code>lxml.html</code> elements
accidentally returned a "smart string"
without additional information. It now returns a plain string.</p>
</li>
<li>
<p>LP#2109931: When building lxml with coverage reporting, it now
disables the <code>sys.monitoring</code>
support due to the lack of support in <a

`commonmark` has been deprecated in favor of `markdown-it-py`, and its
type hints have been [removed from
typeshed](https://github.com/python/typeshed/issues/13725).
This switches the release script to use `markdown-it-py` instead of
`commonmark` for parsing the `CHANGES.md`

<li>Fix usage of <code>typing_extensions.TypedDict</code> nested inside
other types

not allowed by the
type system but worked on older versions, so we maintain support.</li>
