&lt;p&gt;on Ubuntu 16.04. This was discovered with libmongoc, since it was using whichever version of zstd was installed on the system, and Ubuntu 16.04 comes with version 0.5.1 by default.&lt;/p&gt;</description>

Do you know if any other drivers might have similar issues?&lt;/p&gt;</comment>

Then I think it wouldn&apos;t offer it in the negotiation phase at all.&lt;/p&gt;</comment>
