</h1>
<p><code class="language-plaintext highlighter-rouge">lakefs-client</code> is now deprecated, and we will shortly publish its last
release to PyPI.</p>
<h2 id="what-is-changing">
<a href="#what-is-changing" class="anchor-heading"><svg viewBox="0 0 16 16" aria-hidden="true"><use xlink:href="#svg-link"></use></svg></a> What is changing?
</h2>
<p>Ever since we released lakeFS 1.0, we have supported these two SDKs to program for lakeFS with Python:</p>
<ul>
<li><a href="https://pypi.org/project/lakefs/"><code class="language-plaintext highlighter-rouge">lakefs</code>, the lakeFS High-Level Python SDK</a>. This is offers a structured easy way to use lakeFS from lakeFS.</li>
<li><a href="https://pypi.org/project/lakefs-sdk/"><code class="language-plaintext highlighter-rouge">lakefs-sdk</code>, the lakeFS HTTP API</a>. This is
auto-generated from the lakeFS OpenAPI spec. It is guaranteed to support
all lakeFS API actions. And it is covered by the lakeFS SDK interface
guarantees.</li>
</ul>
<p><strong>These clients will continue.</strong></p>
<p>Before lakeFS 1.0 we would publish only:</p>
<ul>
<li><a href="https://pypi.org/project/lakefs-client/"><code class="language-plaintext highlighter-rouge">lakefs-client</code>, a legacy older version of the lakeFS HTTP
API</a>. This too was auto-generated. However it cannot
provide interface guarantees. <strong>At no time could this client ever provide
forward- or backward- compatibility at the source code level.</strong></li>
</ul>
<p>We have continued to publish <code class="language-plaintext highlighter-rouge">lakefs-client</code> since the 1.0 release, in order
to provide continued support for existing users of this legacy Python SDK
client. But there are better alternatives, and its continued presence only
confuses our users.</p>
<p>Now it is time to deprecate this client, and we will stop publishing it at
or after the version 1.40 release of lakeFS.</p>

</h3>
<p>All existing uses will continue to work. Obviously we will not be pulling
these published versions because of this change. We will stop publishing
new versions of these clients.</p>

<p>Migration is covered by <a href="https://docs.lakefs.io/project/code-migrate-1.0-sdk.html#migrating-sdk-code-for-python">Migrating to 1.0</a>. In most
cases the changes are quite simple.</p>

</h3>
<p>No.</p>
<p>Version 1.40 will be the last release of lakeFS to include a new version of
the legacy client. In order to use any <em>new</em> features of the lakeFS API,
you will need to upgrade your programs to use <code class="language-plaintext highlighter-rouge">lakefs-sdk</code>.</p>

</h3>
<p>Yes.</p>
<p>A program that uses any 1.x version of <code class="language-plaintext highlighter-rouge">lakefs-client</code> still uses 1.x
versions of lakeFS APIs. Its usage of those APIs is still covered by the
lakeFS interface guarantees, so it will continue to work with future 1.x
releases.</p>

</h3>
<p>That is also going away. However we see much less usage of it.</p>
