General availability: Azure API Management updates - August 2021

Published date: September 01, 2021

A regular Azure API Management service update was started on August 19, 2021. It includes the following new features, bug fixes, and changes, along with other improvements.

New features:

  • The availability zones feature is now supported in four new regions: South Africa North, Germany West Central, Korea Central, and Norway East.
  • The rate-limit-by-key policy now supports policy expressions in the calls and renewal-period attributes. The renewal-period's upper limit of 5 minutes still applies.
  • The upper limit of the max-size attribute of the validate-content policy can now be increased beyond 100kB through Azure support.
  • API inspector's traces now include the service name property.
  • API Management is now more responsive to moves and cluster scale-outs of Service Fabric backends.
  • API Management now supports custom domain certificates encrypted with the AES256_SHA256 algorithm.
  • The Network Status management API response and page in the Azure portal now include details about the connectivity to Azure Application Insights for services with configured Application Insights loggers.
  • The "Publish" button on the "Developer portal overview" page of API Management services in the Azure portal now uses the new Portal revisions API, which makes it easier to publish the portal for virtual-network-injected services.
  • Clicking on a grid's row in the "Subscriptions" page of Azure API Management services in the Azure portal now brings up a new subscription editing interface.

Details on all these new features, bug fixes, and other changes can be found here on Github.
