customers can update their policy using the json documented under configuration, aws accounts, documentation • object version change tracking o change tracking is now implemented for all major object types including zecs, broadcasters/clusters, sources, channels, and most target types o the feature is not yet implemented for mediaconnect/medialive channels and targets o the change tracking panel logs the change history and user and provides individual, and batch revert tools idp new insights and incidents integration o insights multi select broadcasters, sources, or targets and clicking the insights button displays their metrics on a single panel allowing comparison and easy identification of outliers o incidents on source or target details page there is now an incidents tag showing all the incidents the selected object has been in • idp new incidents dashboard o easier at a glance comparison – compare metrics from different objects in the same graph, rather than having to scroll through separate graphs for each o graph annotations – allows user to mark points on the timeline, note important moments during the incident, or external events such as maintenance or equipment failures • show broadcasters without cluster grouping o users can now toggle the broadcasters table between clusters and broadcasters to list and work with a table of all broadcasters, providing the appropriate column options and multi selection tools • broadcaster recovery o when deleting or disabling a broadcaster the user is now presented with an option to migrate all current objects to another broadcaster o triggering the recovery is currently manual only • target pid mapping o pid mapping, previously available in sources, is now available on targets o the feature supports configurations for delivering multiple pid mapped variants of a single channel to meet differing target requirements • private ip auto detection o on aws/azure/gcp broadcaster zm will automatically track the current private ip allowing for private ip streaming without manual configuration • tag multi viewer integration o configure tag mcm 9000 instance to create new multiview source in zen master from user selected zen master sources • live events re work o the update provides a revamped live event dashboard to better accommodate new and future features o custom stages allow users to add and rename as many event stages as needed for the event, such as ▪ ‘pre game build up’ ▪ ‘post match studio analysis’ ▪ etc o clip insertion tools allow the user to specify one or more promo clips which can be played out from clip start on stage transitions or manual insert once the clip is finished the output reverts to the primary feed additional improvements and changes the following additional improvements and changes were implemented in this release • added in application features guide on incidents page • added features guide for tags and user permissions • added support for aws g5g arm with nvidia gpu instance types • added an active incidents widget to the main dashboard • added min/max bitrate graphs for mediaconnect sources • added maintenance, muted, and muted until to broadcaster api calls • added all failover modes to zixi pull targets o alt host o stream switch o hitless merge • added auto bonding support for zixi push targets o the configuration will use all nics available to the broadcaster at the time of creation • added "ongoing" incident count to the left side main navigation menu • added pagination support to failover channel api • updated aws amis that zen master uses for broadcasters to reduce costs and improve security o initially this will only apply to new or updated clusters and not aws g5g instance types • exposed auto latency toggle on zixi pull sources • exposed verify stream id for srt listener sources • exposed stream id for srt caller targets • failover channels are no longer limited to 3 sources • de escalating warnings/errors now state when the status will clear • active objects table enhancements o filters o limited multi select and multi edit • active source in a failover source/channel is now highlighted in diagrams and details pages • broadcaster private/public ips are now displayed in the broadcaster details panel • failover sources now allow switching back to a preferred source (requires zixi broadcaster v17) • network ids are now consistent in incidents and networks • saving after editing an object will now automatically paginate to the page that has the relevant object in the table bug fixes the following issues were resolved • fixed mediaconnect sources not using dtls when pushing to a zm cluster • fixed targets not displayed on grids when selecting with tags • fixed billing codes applied inconsistently on auto pulls • fixed v16+ broadcasters issue on gcp nvidia machines • fixed incorrect instance type displayed on aws broadcasters after an auto recovery if the type was changed on the cluster • fixed missing validation allowing users to create infinite loops with sources that use other sources, such as an inter cluster source that pulls itself • fixed multiple issues with non admin users unable to use zec sources • fixed "failed to acquire streaming ip address" warning spam under some over load conditions • fixed object locations defaulting to north dakota • fixed multi editing live events providing an option to update events profile • fixed missing error message when attempting to delete a pid mapping profile that is already in use • fixed an issue preventing webrtc playback from working when the source is working but has de escalating errors • fixed mediaconnect source details page failing to open from links • fixed downloading an event log failure for some

creating conflicting srt targets • fixed srt pull target hostname configuration not working when the target is assigned to a mediaconnect flow • fixed aws iam role failing to update in aws backend on cluster updates • fixed users being prevented from editing the encryption mode on srt targets • fixed c7g instances never launching in aws • fixed an unexpected aws error when editing very old aws clusters • updated aws iam policy to remove harmless warnings in aws console • non admin users will no longer get logged out of zm when navigating to the networks page • deleting a remote access object no longer leaves the object in a broken state in the table • attempting to delete a broadcaster with termination protection now shows proper error message • pid mapping failures now have a detailed error message
