New features and enhancements

Cipher auto-update

Dynatrace Managed installer

We updated the default cipher suites and added a cipher auto-update parameter to the Dynatrace Managed installer. It's set to off for existing nodes and on for new clusters (new nodes being added to the existing cluster keep parameters of a seed node).

When set to on, you set the cipher suites and protocols to default after each upgrade or reconfigure. If you manually change ciphers or protocols (using --ssl-ciphers or --ssl-protocols parameters), the cipher auto-update gets disabled (automatically set to off).
