Changes

• ACAP documentation:
  • The ACAP documentation has been restructured to follow the Diátaxis documentation framework.
  • Added instructions on how to Sign an ACAP application as a non-TIP partner.

Bug fixes

• Fixed an issue where a slash (/) in the friendlyName field would break the tar step in acap-build.
• Fixed the missing manifest schema upgrade functionality that was announced in 12.10 but not included in SDK 12.10.0. When running acap-build with validation enabled, the SDK now automatically sets the manifest schema version to the highest supported major version in the SDK. Available in SDK 12.11.0 (and 1.15.2).

Upcoming changes

• Message broker removal: This LTS release is the last to include the Message broker API. It will be removed in AXIS OS 13.0. Developers should migrate to the Device Data Hub API for inter-application communication.
• API removals in AXIS OS 14: The axhttp API is planned for removal in AXIS OS 14.0. For officially supported alternative APIs, see the API compatibility guide.
