            <title>[CDRIVER-463] what&apos;s the corresponding relation between mongodb server and c driver</title>
                <link>https://jira.mongodb.org/browse/CDRIVER-463</link>
                <project id="10030" key="CDRIVER">C Driver</project>
                    <description>&lt;p&gt;I upgrade mongodb server to version 2.6.5 from 2.0.2 recently. It seems that c driver vesion 0.7.1 do not support mongodb 2.6.5. No data can be inserted into mongodb since I upgrade mongodb. So I want to know what&apos;s the corresponding relation between mongodb server and c driver? Is there a version of c driver compatible for both mongodb  2.6.5 and 2.0.2? It&apos;s important to me because we are runing both 2.6.5 and 2.0.2.&lt;/p&gt;</description>

&lt;p&gt;The C driver versions &amp;gt; 1.0.0 should support mongod as far back as 2.2, so 2.2.1 should be supported.  That said, minor versions of the server don&apos;t receive security updates, so I&apos;d advise that you try to upgrade to 2.2.7 if possible.&lt;/p&gt;

&lt;p&gt;Regards,&lt;br/&gt;

Thanks  very much for your help. I am sorry that I make a mistake about my old mongodb version. The last version I used is 2.2.1.  Is 2.2.1 more similar to 2.2.7 that c driver 1.0.2 may support better?&lt;br/&gt;
thanks again.&lt;/p&gt;</comment>
                            <comment id="766940" author="jason.carey" created="Tue, 18 Nov 2014 16:06:10 +0000"  >&lt;p&gt;I&apos;m sorry to hear you&apos;ve run into problems upgrading your installation of mongodb.  Unfortunately you&apos;re running a configuration that we no longer support.  The current stable revision of the C driver is 1.0.2 and the oldest version of mongod that we specifically test against with that driver is 2.2.7.  Upgrading will also require a rewrite of your client code, because the api for the c driver changed significantly between the 0.7.1 and 1.0.0.  On the plus side, after you&apos;ve made the upgrade to 1.0.0 you&apos;ll get a guarantee of abi stability from us until 2.0.0, so that should be the last time investment you&apos;ll have to make for a while.&lt;/p&gt;

&lt;p&gt;As to whether the newer version of the c driver will work with 2.0.2, I&apos;m honestly unsure.  I don&apos;t test against that configuration, so I can&apos;t promise that if it works today that it will always work, but 2.2 is quite similar to 2.0.  So keeping in mind that some tests won&apos;t pass (if nothing else aggregation didn&apos;t exist in 2.0, so those methods won&apos;t work), you may be able to get some functionality.&lt;/p&gt;

&lt;p&gt;Latest stable revision of the c driver: &lt;a href=&quot;https://github.com/mongodb/mongo-c-driver/releases/tag/1.0.2&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://github.com/mongodb/mongo-c-driver/releases/tag/1.0.2&lt;/a&gt;&lt;br/&gt;
Docs for that revision: &lt;a href=&quot;http://api.mongodb.org/c/1.0.2/&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;http://api.mongodb.org/c/1.0.2/&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;Thanks for using the C driver,&lt;br/&gt;
