With this release, the oldest supported OneAgent versions are:
Standard Support
Enterprise Success and Support
1.201
1.195
OneAgent for JavaScript
We changed the algorithm for CLS to follow the evolved version as defined in Evolving the CLS metric.
This could lead to jumps in CLS metrics, but it should only improve the CLS value.
OneAgent for iOS
We removed the crash forwarding feature for email and Hockeyapp.
Host group and network zone validation
OneAgent now performs additional validation for host group and network zone assignment when loading from the configuration file. Entries that don't conform to the host group or network zone naming pattern are rejected.
We recommend using the oneagentctl command or OneAgent installation parameters to assign a host to a host group and network zone.
New binaries in the installer package
We added the following binaries to the OneAgent installer package with all their required permissions and capabilities:
OneAgent now writes custom dtdTraceTagInfo protocol tags to the MQ header in folder MQRFH2/usr, but only if the MQRFH2 extension header is present before an MQOutput node (optionMqTaggingMB:true). As a fallback, custom MQ headers are still created (optionMqTaggingFallbackMB:true). For more information, see Services.
