+### Bug Fixes
+
+
+- *(build)* Set default value for secondary CA cert to false
+([MEN-8351](https://northerntech.atlassian.net/browse/MEN-8351)) ([aca8e5d](https://github.com/mendersoftware/mender-mcu/commit/aca8e5d4788aa4cb428220e56914bb17db8f29c7))  by @lluiscampos
+
+
+  The secondary CA cert is really optional, as a custom Mender Server
+  could use the same domain for both API calls and Artifacts storage.
+  
+  Set `MENDER_NET_CA_CERTIFICATE_TAG_SECONDARY_ENABLED` default to `n` and
+  instead select it when selecting hosted Mender option(s).
