5		-**Hi there, eMagiz developers!** In the last few weeks, we have worked hard on improving our next-generation architecture and introduced alerting functionality on top of our event streaming pattern based on user feedback. Furthermore, several smaller feedback items and bugs have been resolved with this release. So without further ado, let us dive into all we have to offer.
	5	+**Hi there, eMagiz developers!** In the last few weeks, we have worked hard on improving the migration towards our next-generation architecture as well as improved the general behavior when running on the next-generation architecture. Furthermore, several improvements have been made to our own infrastructure to ensure that all data flowing via this infrastructure now more and more customers are migrating can be handled as good if not better as before.

9		-This release expands our alerting functionality into the event streaming pattern. As of now, one new "static" alert has been introduced for all clients (using event streaming), and two "dynamic" alerts have been introduced that you can configure yourself if there is a need for it.
	9	+//__"Stop" action when running a hybrid situation is not causing issues anymore__//
	10	+Before, it could happen when running a double-lane setup in a hybrid situation (i.e karaf based runtimes on top of the next-generation architecture) that the stop action on said runtime would not stop the runtime but "kill" it. With this release that behavior is changed.

11		-The "static" alert we have added raises an alert (and a subsequent email) when the actual topic size crosses the threshold of 80% of the configured maximum retention size on a topic. This alert provides insights into whether messages on it are deleted due to a size or time constraint. In cases where data is deleted, the topic was too full way before the messages should have been removed due to the retention hours constraint. This alert can indicate that messages might be deleted before consumer groups had the option to consume the messages.
	12	+{{info}}Note that this fix is part of a new runtime image for the karaf based runtimes. The impact of this can be read [[here>>doc:Main.eMagiz Academy.Microlearnings.Crash Course.Crash Course Platform.crashcourse-platform-deploy-execute-deployment-plan-gen3.WebHome||target="blank"]]{{/info}}

13		-The two "dynamic" alerts we have added mimic the alerting on the queue level we already offer to the community.
	14	+//__Removed certain dependencies between Deploy Architecture and Releases__//
	15	+In this release, we have removed several specific dependencies that caused confusion between the functionality in the Deploy Architecture overview compared to the functionality that is linked to a release and specifically the deployment of a release.

16		-
17		-The first new "dynamic" alert allows you to raise an alert once the number of messages on one (or more topics) is less than a certain number per defined time unit. So, for example, you can configure an alert once the number of messages placed on a topic called "Exception" is less than 15 messages within 5 minutes.

20		-
21		-The second new "dynamic" alert allows you to raise an alert once one (or more) consumer groups are more than X messages behind on one or more topics. The configuration of this is comparable to what we saw before.

25		-== **3rd generation improvements** ==
26		-
27		-//__Increased grace period for shutdown__//
28		-In this release, we have increased a container's grace period to shut down before it is forcefully shut down. This should reduce the chance of unwanted failover behavior within your model.
29		-
30		-//__Update at once or not__//
	17	+//__Improved validation errors on invalid configuration of HTTP outbound components__//
31	31	This release fixes and re-introduces the option to execute your actions on the eMagiz per zone or all at once when running in a double-lane Docker setup.
32	32
33		-//__Improved user feedback while executing a deployment plan__//
34		-This release introduces additional feedback to the user when the deployment plan is executed. This is noticeable when a step cannot be executed properly. The relevant information about why this cannot be executed is shown to the user. This way, they can take this information and act upon it instead of assuming everything went well.
	20	+//__Improved migration behavior__//
	21	+This release introduces several improvements with regards to the migration behavior via "Transfer settings from Design". Among these are a smoother migration of your JMS (and backup JMS) process, additional feedback given to the user and feedback when the migration process is finished.

36	36	//__Improved auto-healing when running in a hybrid situation__//
37	37	In situations where you run in a hybrid situation (i.e., partly next-gen and partly the current generation), we have improved the auto-healing functionality in case an "out of memory" appears on a runtime running in the current generation but on a next-generation architecture.
