But could you confirm, whether the applications I have created using older versions support the latest SDK?

&lt;p&gt;You can still access the previous SDK version in the Toolchain Manager. Open the &lt;em&gt;nRF Connect for Desktop&lt;/em&gt;, select the &lt;em&gt;Toolchain Manager&lt;/em&gt; and go to the &lt;strong&gt;Settings&lt;/strong&gt; on the top left. From here, &lt;strong&gt;de-select&lt;/strong&gt; the &amp;quot;&lt;em&gt;Show only 3 newest minor versions&lt;/em&gt;&amp;quot;.&lt;/p&gt;

&lt;p&gt;Now when you go back to the &amp;quot;&lt;em&gt;SDK Environments&lt;/em&gt;&amp;quot;, you can find all the previous version available for installation.&lt;/p&gt;
&lt;p&gt;Regards,&lt;/p&gt;
