--**Hi there, eMagiz developers!** We have done much work for state generation, so that you can derive more information from your data! Examples are enrichment, aggregation, change detection and duplicate detection. State generation functionality is only accessible for models with an add-on state generation license. Next to state generation, several improvements regarding the alignment of components have been made. Moreover, performance improvements and bug fixes have been implemented. Lastly, a change in the metrics storage duration has been performed.
++**Hi there, eMagiz developers!** In the last couple of weeks, we worked hard on building several essential things that will be released later this Q. On top of that, we finished additional features for our 3rd generation runtime that give you chirurgical precision when doing maintenance on a model. Among the other features, we have a new event streaming graph and general updates to our platform.
--== **State Generation** ==
++== **Start/Stop Flows** ~*~* ==
--//__New components__//
--The following components have been added:
--* Aggregator: reverse of the splitter, used to combine multiple messages into a single one.
--* Infinispan metadata outbound channel adapter: used to (temporarily) store metadata, which can be used to enrich messages, or make decisions in filters or scripts.
--* Content enricher: used to add properties to the payload of messages, similar to what the header enricher can do for headers.
--* Duplicate detector: support object used to detect duplicate messages for a certain key on an inbound channel of a flow component. Duplicates can be marked or discarded.
--* Infinispan support objects, supporting the aggregator, metadata outbound channel adapter and content enricher.
++{{warning}}Note that depending on the alert, this functionality will only work when your JMS server is running on the 3rd generation runtime{{/warning}}
--//__SpEL functions & JSON__//
--Added SpEL functions for:
--* Encoding & decoding Base64, Hex and hmac.
--* Date retrieval (currentDateTime, currentEpochMilli, currentEpochSecond).
--* Date conversion (DateTime to Epoch, Epoch to DateTime, DateTime formatter and DateTime parser).
++To enhance your options when running into problems or when maintaining your solution in a Production environment, we have added a new feature to our Deploy phase called "Start/Stop Flows." You can access this functionality via the "Deploy Architecture" overview in Deploy. On the runtime level, you can open the context menu and select the "Start/Stop Flows" option.
--Added support for SpEL property accessors for XML and JSON, meaning that you can read message payloads in SpEL expressions easily. For example, to retrieve the value for 'id' in the following JSON String: `{"id":"123"}`, this SpEL expression suffices: `payload.id`.
++[[image:Main.Images.Release Blog.WebHome@192-release-blog--start-stop-flows-context-menu.png]]
--Added support for `#JsonPath` usage in SpEL expressions.
++After selecting the option, eMagiz will open a pop-up where you can stop and start the starting point of each flow deployed on that runtime. This effect is that the flow will process no new messages, but the flow will still process all remaining messages after stopping the flow. To prevent a flow, you select a flow and press the Stop button. To start it again, press Start.
--//__New image version 2.0.0__//
--The above functionalities are features of the new image version 2.0.0. Important to note is that the library used for Code Mappings has been changed. Changed the library used for Code Mappings. Any customer with Gen3 runtimes and code mappings is required to reset their infra flows prior to deploying on image 2.0.0.
++[[image:Main.Images.Release Blog.WebHome@192-release-blog--start-stop-flows-pop-up-menu.png]]
--//__Component pages__//
--Pages to add the new components have been created. Forms have been created nicely with proper help texts. The EHCache cache manager has been removed.
++{{info}}Only in "Start Editing" mode can you start and stop specific flows{{/info}}
--== **Metrics Storage Duration** ==
--We will change the retention of monitoring data of different environments. For minute level data, it will be kept for test, acceptance and production environments for 5, 7 and 30 days respectively. Then the minute level data will be reduced to hour level data then will be stored for test, acceptance and production for 3, 6 and 12 months respectively.
++== **Manage overview Event Streaming** ~*~* ==
--[[image:Main.Images.Release Blog.WebHome@release-blog-207-aligned-state-metrics-storage.png]]
++To enhance the  observability of your event streaming solution while running in the 3rd generation runtime architecture, we have added a new feature to our Manage phase called "Event streaming statistics." You can access this functionality via the "Monitoring" menu in Manage. Then, you can see metadata information on all your topics by clicking on the "Event streaming statistics" overview. Among others, you can see whether data is consumed, on which topic much data is produced, and whether consumers are lagging in consuming data.
--== **Feedback Items** ==
++[[image:Main.Images.Release Blog.WebHome@192-release-blog--event-streaming-overview-manage.png]]
--//__Import from store__//
--The button 'Import from Store' in Design will directly open the store instead of showing a pop asking whether the store should be opened.
++== **Feedback items ** ==
--//__Save and cancel buttons placement__//
--The save and cancel buttons have been placed slightly further apart from each other to avoid misclicking.
++We have also solved other feedback items besides the flow designer's critical updates.
--//__User session times__//
--The user session times for 3rd generation runtime dashboards have been extended, so that the user is not thrown out of the model when using the Manage phase for longer than an hour.
++//__Topic configuration calculation__//
++With this release, we have simplified the configuration of settings on the topic level to enforce certain best practices within the portal and simultaneously make it easier to configure topics.
--//__Cancel and next buttons order__//
--The order of the cancel and next buttons when creating a new trigger has been changed to increase alignment across the platform. Now, all cancel buttons are placed on the right of a 'next' or 'save' button.
++//__Make preparation step in deployment plan visible__//
++For deployment on the 3rd generation runtime to work, the portal needs some preparation work. We have now made this step explicit and part of the deployment plan.
--//__Data sink page__//
--The data sink page has been moved to the “Explore” tab.
++{{warning}}Make sure to update your deployment plan accordingly to ensure that the preparation step is not forgotten{{/warning}}
--//__Unused images removal__//
--When a release is removed, the related unused images in the on-premises machines will be removed as well.
++//__3rd generation runtime debugger feedback__//
++We have improved the user experience of the 3rd generation runtime debugger with this release by solving various feedback items we noticed in the first adoptions of the functionality.
--//__Flow Designer performance__//
--Performance improvements for the Flow Designer have been implemented.
++//__No "Shift key" needed anymore to select multiple items in the flow designer__//
++As of now, you do not have to hold your "Shift key" when you want to select multiple items in the flow designer. This will make it easier to select parts of flows.
--//__Properties with special characters__//
--When a user would migrate to gen3 and deploy their release containing properties with special characters, certain flows could not find the correct values to properties anymore or could not find the properties altogether. With this release, special characters such as a backslash do not break properties after deployment.
++//__User Management synchronization now happens in one step__//
++With this release, we have updated the synchronization process between Design and Deploy concerning User Management. When you press the "Transfer from design" button, both Users and Roles will be synchronized.
--//__Hidden flow fragements__//
--When importing items from the store, flow fragments that are hidden in design will be listed under the versions in create.
--
--//__Resources disappearances__//
--Resources would disappear in the flow designer when pressing Cancel on selecting a new resource. With this release, resources without a name will not trigger error messages when users select components.
--
--//__Error channel for all inbounds__//
--If there is no custom error handling, Gen3 migration would set the error channel to “errorChannel” only for the first inbound in an entry flow.
--We added a migration step, such that the error channel is set to “errorChannel” of all inbounds in a flow if the custom error handling is set to false.
--
--//__Highlighting resources__//
--The performance of highlighting resources of selected components is improved in Read only mode.
--
--== **Bug Fixes** ==
--
--//__Topic and event-processor names__//
--The styling of the event streaming canvas in the Create and Deploy phases has been altered slightly to make topic and event-processor names more readable.
--
--//__System alignment__//
--The positioning of Systems across Design, Create and Deploy phases are now synchronized to the position of their respective System in the Capture phase. So, systems are aligned regarding positioning across all phases.
--
--//__Error checking__//
--Besides checking error header, the error trigger is now configured to check if an error message contains a term.
--
--//__Alerting__//
--For gen3 models, you will no longer receive alert messages for every error message, every log message of 'level' ERROR, and for memory usage above 80%.
--For gen3 models with event streaming, the threshold to receive the 'Topic approaching maximum size' alert has been increased from 95% of configured size used to 110%.
--The gen3 configurable trigger for error messages has been extended with the option to check whether the 'last-exception' message contained a certain text. This can be combined with the header-value match.
--
--//__Unused containers__//
--Containers are set inactive when they are unused and removed in Design.
--
--//__Error popups when promoting a release version__//
--We fixed an issue that a lot of error popups were shown when you promoted a release version to a next environment.
--
--//__Memory leak__//
--A memory leak when using gen 3 metrics has been fixed.
