<p><em>Sourced from <a

releases</a>.</em></p>
<blockquote>
<h2>gix v0.85.0</h2>
<h3>Bug Fixes (BREAKING)</h3>
<ul>
<li>
<p>avoid duplicate network connection when adopting a remote-controlled
hash kind.
Connections can now be created from detached remotes, internally,
which makes them independent of the underlying repository.</p>
<p>This is breaking as it comes with a cleanup of
<code>Connection</code> lifetimes,
which will break anyone who stores them in a struct. So hopefully
nobody is affected.</p>
</li>
<li>
<p>bound the clone object-hash adoption retry
The clone fetch loop adopts the remote's object format and retries when
it differs from the freshly initialized local repository. Adoption makes
the next iteration's hashes match, but if the reopened repository
somehow
still disagrees the loop would re-handshake forever. Track whether we
already retried and fail with IncompatibleObjectHash on a second
mismatch
instead. The error variant is introduced here, as this is its only
user.</p>
<p>Also silence clippy::never_loop on default (sha1) features, where the
sha256-gated <code>continue</code> is absent and the loop always returns
first pass.</p>
</li>
</ul>
<h3>New Features (BREAKING)</h3>
<ul>
<li>
<p>add leaf-only tree-editor removal via
<code>Editor::remove_leaf()</code>
Motivation comes from <a
href="https://redirect.github.com/gitbutlerapp/gitbutler/pull/14312">gitbutlerapp/gitbutler#14312</a>,
where callers had to split tree-entry deletions from additions to avoid
accidentally deleting a newly-added subtree after adding A/one and then
deleting
A.</p>
<p>Add Editor::remove_leaf() to gix-object and expose it through gix
object tree
editors and cursors. The new API keeps remove() behavior unchanged,
remains
tolerant of absent paths, but returns an error when the target entry
exists and
is a tree.</p>
</li>
</ul>
<h3>Bug Fixes</h3>
<ul>
<li>
<p>adopt the remote's object format when cloning
A clone into a freshly initialized repository hit an
<code>unimplemented!</code>
panic when the remote used sha256, since the local repository defaults
to sha1.</p>
<p>Reconfigure the still-empty local repository to the remote's object
format and retry the fetch, matching git's behavior of inheriting
the remote's hash on clone.</p>
<p>Without the sha256 feature gix_hash::Kind has a single variant, so
the
local and remote hashes can never differ; the mismatch check is compiled
out entirely in that case.</p>
</li>
<li>
<p>write fetched remote symrefs as direct refs
Previously <code>gix</code> had made-up behaviour to 'improve' on
standard Git,</p>
</li>
</ul>
