New features and enhancements

General

To take advantage of performance improvements, the latest security-vulnerability enhancements, and bug fixes, we've upgraded the following cluster node components:
- Cassandra and Elasticsearch will now use JRE 8u292
- Elasticsearch engine is now based on version 7.10
- Other components will now use JRE 11.0.11
Dynatrace Managed is now also supported on:
- Red Hat Enterprise Linux 8.4
- CentOS 8.4
- Oracle Linux 8.4
- Ubuntu 21.04

For more information, see Dynatrace Managed system requirements.

Cluster Management Console

Managing permissions of tens, dozens, or hundreds of environments can be challenging. To increase usability experience in configuring granular cluster permissions, we've improved the Groups overview page. The table got simplified and was enriched with advanced filtering capabilities. You can now build an advanced filter based on:
- Group name with any comparator of {contains, starts with, equals}
- Permissions included in an environment, a management zone, any environment or management zone, a cluster, or an account
- LDAP group name

See an example below:

Advanced filtering for groups overview

We continue to further enhance security by easily automating your API token protection. In this release, we're proceeding with earlier announced change and it's no longer possible to reveal generated token values in the Edit panel once those values have been saved. Remember to store the token in a safe place like a password manager, secret vault, or other password protection services. See the screenshot below, how improved Token Management UI looks like:

Copy token on creation

Token value no longer available
