<p>An update that has seven fixes can now be installed.</p>
<h2>Description:</h2>
<p>This update for go1.24, go1.23, go1.22, go1.21 fixes the following issues:</p>
<p>Changes in go1.24:</p>
<ul>
<li>Use libalternatives only on suse_version >= 1610 and keep
update-alternatives support for older distributions.</li>
<li>
<p>Drop the update-alternatives migration path for libalternatives builds.</p>
</li>
<li>
<p>Packaging: Enable libalternatives for SLE16.1 and Tumbleweed
Refs boo#1245878</p>
</li>
<li>Drop go1.24 dependency on update-alternatives fixes bsc#1264393</li>

the inital version of go1.x.</li>
<li>go1.21 will be the initial version of Go in the bootstrap chain
until gcc gccgo is updated to support a language level newer
than go1.18.</li>
<li>Refs boo#1247816 bootstrap go1.21 with gccgo</li>
<li>Refs boo#1248082 drop unused gccgo bootstrap code in go1.22+</li>
