 Changelog
 ---------
 
+**7.0.0**
+
+- Switched to install from ELRepo KMOD package for CentOS (see https://www.wireguard.com/install/). This change may break installation for systems with custom kernels. The role previously supported custom kernel implicitly because it was using DKMS package (contribution by @elcomtik)
+  
+  Role removes DKMS wireguard package, however it doesn't remove jdoss-wireguard-epel-7 repository. If you don't need this repository, do cleanup by:
+    * remove `/etc/yum.repos.d/wireguard.repo`
+
+
 **6.3.1**
 
 - Support Openstack Debian images (contribution by @pallinger)
