Subject:  General Availability Announcement for Layer7 OAuth Toolkit (OTK) 4.6.4

The Layer7 product group of Broadcom's IMS division is pleased to announce that the Layer7 OAuth Toolkit (OTK) version 4.6.4 is now available! This milestone provides enhancements based on customer feedback. Congratulations to the team for reaching this important milestone while continuing to provide important enhancements to our customers!

Here are the highlights of the Layer7 OTK 4.6.4 release:

• OTK Usability Improvements to Centralize Routing Assertion Configuration - provides a common encapsulated assertion to allow the selection of the private key used for routing to be configured in a single location. Customization is also supported for additional configurations.
• Inactive Client Detection - provides the ability to configure client activity detection and provides a new API endpoint to retrieve a list of clients that have not been active for a specified period of time.
• Provide configurable support for authentication for the dynamic client registration endpoint - adds the ability to configure optional authentication for the Dynamic Client Registration endpoint.
• [Preview] Layer7 Operator support for OTK - Single Ephemeral GW - along with Layer7 Operator 1.2 (coming soon), OTK may now be managed and deployed along with the Operator when using the OTK configured to have all components (i.e. DMZ and internal) on the same instances in an ephemeral gateway installation (i.e. no gateway DB used).
• New DB connection for client table reads - adds the ability to configure different DB connection properties for reading the client table. This allows configuration such as primary and failover settings to differ for this table.
• MySQL 8.4 Support - MySQL 8.4 is now supported for the OTK DB. 
• Improvements for Backward compatibility - improved default handling and additional customization points have been added to provide more flexibility for customers upgrading to newer OTK versions to ensure new features do not potentially impact existing configurations where possible.
