 * Istio service mesh addon revision asm-1-19 is no longer supported. If you are still using this revision on your cluster, please upgrade for continued support. More information about mesh upgrades and version support can be found [here](https://aka.ms/asm-aks-upgrade-docs).
 * 1.30 is the next LTS version after 1.27. Customers will have at least 6 months of migration time available between 1.27 LTS to 1.30 LTS i.e before the 1.27 LTS goes End of Life by July 2025. Refer [long term support](https://learn.microsoft.com//azure/aks/long-term-support) for more information.
 * Container Insights has automatically migrated from legacy authentication to managed authentication on AKS clusters where the Container Insights addon was enabled with legacy authentication. This migration occurs when any feature, such as the cost-analysis addon or authorized IP ranges, is enabled using the preview API version 2023-07-02-preview or later. This unintended migration has caused monitoring to break, this issue has been fixed for new clusters. To mitigate this issue on existing clusters, re-onboarding or re-configuring of Container Insights is required.
+* Released improvements to [planned maintenance schedule](https://learn.microsoft.com/azure/aks/planned-maintenance), so that there are no missed or delayed windows. Also you no longer have to wait for 24 hours   between the creation or update of a maintenance configuration and the scheduled start time, this will now only take few minutes going forward.
