Release v1.28.0 is a hotfix release to address a deadlock in the Netdata Agent. We intended to release this hotfix as v1.27.1, but we can't backtrack on a release once we've begun to publish new Docker images and binary packages on other platforms.
If the Agent-Cloud link (ACLK) connection drops and the Agent fails to queue an on_connect message, it also fails to properly release a lock in the web server thread.
