+### Minimal mongodb version is now `4.2.0`
+
+Mongodb version before `4.2.0` have been dropped (`3.6` & `4.0`) as they are now unsupported by the latest mongodb drivers
+and are EOL for a couple of years.
+
+This also means `mongodb-memory-server-global-4.0` has been dropped and wont receive a update to 11.0.0.
+
+Distribution support has been adjusted to only contain 4.2.0 and higher as well, this means the following are now the minimal versions:
+
+- Ubuntu: 16.04
+- Elemtaryos: 4
+- Linux mint: 18
+- Debian: 9.2
+- Rhel: 6.2
+- Fedora: 12
+
 <!-- ### Mongodb Driver Version upgraded to 6.x
 
 The used MongoDB Driver version is now `6.7.0`.
