5		-**Hi there, eMagiz developers!** In the last few weeks, we have work hard on improving our next generation architecture and introduced alerting functionality on top of our event streaming pattern based on user feedback. Furthermore there are several smaller feedback items and bugs that 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 and the general behavior when running on the next-generation architecture. Furthermore, several improvements have been made to our infrastructure to ensure that all data flowing via this infrastructure now that more and more customers are migrating can be handled as well, if not better, as before.

7		-== **Event streaming alerting** ==
	7	+== **3rd generation improvements and bug fixes** ==
8	8
9		-With this release we expand our alerting functionality into the event streaming pattern. As of now one new "static" alert is introduced for all clients (using event streaming) and two "dynamic" alerts are introduced that you can configure yourself if there is 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.
10	10
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 whether messages on it are deleted due to a size or time constraint. In cases where data is deleted becomes the topic was too full way before the messages should have been removed as a result of the retention hours constraint this alert can be seen as an indication 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}}
12	12
13		-The two "dynamic" alerts we have added mimic the alerting on queue level we already offer to the community.
	14	+//__Improved efficiency in deploying a release__//
	15	+This release improves the efficiency of the "prepare release" step needed when deploying on the next-generation architecture.
14	14
15		-[[image:Main.Images.Release Blog.WebHome@197-release-blog--new-alerting-options.png]]
	17	+//__Removed specific dependencies between Deploy Architecture and Releases__//
	18	+In this release, we have removed several explicit dependencies that confused the functionality in the Deploy Architecture overview compared to the functionality linked to a release, specifically the deployment of a release.
16	16
17		-The first new "dynamic" alert allows you to raise an alert once the total 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 message placed on a topic called "Exception" is less than 15 messages within 5 minutes.
	20	+//__Improved validation errors on the invalid configuration of HTTP outbound components__//
	21	+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.
18	18
19		-[[image:Main.Images.Release Blog.WebHome@196-release-blog--alert-config-example.png]]
	23	+//__Improved migration behavior__//
	24	+This release introduces several improvements concerning the migration behavior via "Transfer settings from Design." Among these are:
	25	+A smoother migration of your JMS (and backup JMS) process.
	26	+Shortening of names that otherwise would be too long, additional feedback given to the user.
	27	+Feedback when the migration process is finished.
20	20
21		-The second new "dynamic" alert allows you to raise an alert once one (or more) consumer groups is more than X number of messages behind on one or more topics. The configuration of this is comparable as we saw before.
	29	+//__Additional checks when deploying__//
	30	+This release introduces additional checks when deploying. Among others, we have added a check to prevent you from deploying two flows that use the same resource with differing versions. Not stopping this can cause issues with deployments and even worse with the functional behavior of the flows, as it leads to the situation in which a validation error might trigger on one offramp but not on the other.

25		-== **3rd generation improvements** ==
26		-
27		-//__Increased grace period for shutdown__//
28		-In this release, we have increased the grace period a container gets to shutdown before it is forcefully shutdown. This should reduce the chance of unwanted failover behavior to pop-up within your model.
29		-
30		-//__Update at once or not__//
31		-This release fixes 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		-
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 of 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.
35		-
36		-//__Improved auto-healing when running in a hybrid situation__//
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.
38		-
39		-== **Feedback items ** ==
40		-
41		-//__Make sure the message format can be viewed without "Start editing"__//
42		-With this release, we have ensured that when you navigate to Design -> System message you can see the message format (i.e. XML, JSON or EDI) without entering the "Start Editing" mode.
43		-
44		-//__Various styling improvements in the flow testing functionality__//
45		-Various smaller styling improvements have been added to the flow testing functionality to improve the overall user experience. For a complete list and more details please check out the release notes.
