Detail on the new features and enhancements introduced in MKE 3.5.3 is presented here, including:

Account lockout

MKE 3.5.3 supports an account lockout feature wherein log in attempts are blocked following a set number of unsuccessful log in attempts.

Image pruning

Administrators can now schedule the cleanup of unused images, whitelisting the images they want to keep.

Interlock proxy NGINX debugging mode

The Interlock proxy NGINX can now be run in debugging mode, which must be manually enabled.

Mirantis strongly recommends that you use debugging mode only for as long as is necessary, and that you do not use it in production environments.

Calico 3.19.3

MKE promotes Calico to version 3.19.3 when you upgrade to MKE 3.5.3.
