Important Changes

The following changes require manual adjustments to current installations.

Configuration Change: Memory Sizing

The default memory sizing for the Java-based App Suite Middleware has been changed from 8192 MB (8 GB) to 2048 MB (2 GB). Installations currently running without this setting explicitly defined in their configuration might break. Please set the memory size explicitly in your configuration to avoid any issues.

When running helm, use --set core-mw.resources.javaOpts.memory.maxHeapSize=8192 to change the memory size back to 8 GB. This can also be added to the values.yaml file. Memory requests and limits also need to be adjusted accordingly (like, maxHeapSize +50%). Those values are defined in core-mw.resources.{limits,requests}.

FCM HTTP API Deprecation / Removal

Google has officially announced the deprecation of the existing HTTP API for sending push notifications via Firebase Cloud Messaging (FCM), effective from June 20, 2023, with plans to shut it down on June 21, 2024. As a replacement, a new FCM API, known as "v1," has been introduced. A Migration Guide is available to assist you in transitioning to the new API.
