Named Queries Fixed Named Query tabs will now only show the name and will not change to the path when renaming or opening.
Designer Fixed Fixed several export categories
Named Queries Fixed Fixed a class not found exception when executing named query tests. Note: Named Queries created in 7.9.4-beta1 will no longer deserialize successfully.
Designer Fixed SFC Monitor Component now retains custom properties after window close.
Scripting Fixed Saving a project with gateway tag event scripts that do not correctly compile can lead to subsequent errors when saving the project.
Gateway Web Interface Fixed Fixed navigation glitch on Security Policy edit page.
Client Fixed Based on data, the client tag history cache can end up logging IllegalArgumentExceptions when sorting data.
Gateway Fixed Setting the Alarm Journal loggers to trace or debug will no longer throw an UnknownFormatConversionException when querying with Display Path or Source filters.
Gateway Added Functionality Efficiency improvements for gateway functions related to backup creation and restoration, module installation and loading, and EAM backup/module management.
Gateway Fixed Gateway Status Logs page no longer creates multiple polled queries filtering logs or changing pages over a slow network.
Gateway Fixed Fixed UnsupportedOperationException when uninstalling modules.
Redundancy Fixed A remote program could submit large payloads on the redundancy port, causing OutOfMemory errors and a JVM hang. To prevent this behavior, use the Redundancy Settings connection whitelist to restrict which machine is allowed to connect.
Gateway Fixed Added Named Query top-level resource
Gateway Fixed isAlarmActive expression function incorrectly queries remote tag providers for alarms, even when only local provider is specified in tag path.
Gateway Fixed Homepage load speed improved for Gateways with large project counts.
Gateway Fixed Transaction group log message for bad quality trigger reduced to "debug" status
Designer Fixed Added touchscreen support for the Web Browser component.
Designer Fixed Non string parameter types in UDTs cannot reference parent udt parameters (type conversion error encountered).

Designer Fixed Commit message area in publish dialog no longer holds on to old text.
SQLTags Fixed Overridden UDT properties updated or modified on the gateway (through writes or various mechanisms) may not be accurately reflected in tags when edited in the designer.
Gateway Fixed Class loading inconsistencies when starting the Designer and a module has been installed and uninstalled multiple times. Now the Designer's cache is purged of unused jars upon startup, eliminating the inconsistencies.
Gateway Fixed Previously, restoring an Edge backup gwbk on a standard Gateway resulted in a faulted Gateway upon restart. Now, a validation error is displayed on the Restore page instead of attempting to restore the Edge backup.
Scripting Fixed Fixed: Editing UDT instance members with system.tag.editTag
Scripting Added Functionality Added optional throwOnError boolean argument to system.net.httpGet and system.net.httpPost to allow users to return error message body rather than getting an IOException.
Gateway Web Interface Fixed For system performance charts with gaps in the data, the chart zoom would change dramatically when the chart received new data.
Alarming Fixed Alarm Journal will now ignore duplicate events on alarm disable/enable providing the state hasn't changed.
Scripting Fixed Fixed NPE when using getScheduleForDay on composite schedule with no events.
Gateway Web Interface Fixed Gateway Log and Thread status pages display without risk of evaluating cleverly formatted html tags in error messages.
Gateway Fixed The Error Reporting Password in Gateway Settings is now properly encrypted.
Scripting Fixed Modified script hints for system.util.sendMessage, system.util.sendRequest, and system.util.sendRequestAsync.
Scripting Modified Functionality Removed system.util.invokeGateway. Use the more secure sendRequest method instead.
Gateway Fixed Modifying the service access rights for remote tags on the serving gateway to be more restrictive doesn't not take immediate effect on existing remote subscriptions. Also, the browse functions are not correctly restricted by tag provider specific settings.
Gateway Modified Functionality A log message has been added to the wrapper.log that reports how long in seconds for the Gateway to reach RUNNING state.
Native Client Launchers Fixed When using a local /jre folder next to the native client launcher executable, the launcher would select the system JRE instead of the JRE in the /jre folder.
Gateway Web Interface Fixed Removed internal db from gateway search
Gateway Web Interface Modified Functionality CPU and memory charts on the System Performance status page now display the date and time of the selected datapoint.
Gateway Network Modified Functionality Gateway Network connections now send a UUID, which will never change (including when a backup gwbk is restored). The UUID will be used to better identify remote Gateways, which eliminates the problem of another connection being created if a remote Gateway system name is changed. This change is backwards compatible, and older Gateways will still be able to connect with Gateways that use UUIDs.
EAM Fixed EAM agents will now update the controller name in the Agent Settings if the controller's Gateway system name changes.
EAM Fixed EAM Remote Upgrade Assistant now updates lib/install-info.txt with the new Gateway version during system upgrade.
EAM Fixed Agent recovery no longer throws a Serialization exception when using a 7.8 Agent with a 7.9 Controller
EAM Fixed Temporary .modl files in the <java.io.tmp>/metro folder were not deleted after execution of the EAM backup task.

EAM Fixed Archived modules sent via the EAM Install Modules task were missing the ".modl" file extension when saved on the agent Gateway.
NJ Driver Fixed Fixed array address parsing when contained within an array of structs.
NJ Driver Fixed Improved request/response size calculation for the Omron read optimizer.
Alarm Misc Fixed Alarm status from remote tag provider in subscribe mode gets stuck when alarm is disabled
Alarm Gateway Fixed Synchronization issues in redundancy could result in alarms being "abandoned" in a pipeline, causing them to not reflect their correct clear or ack state. Alternatively, on multiple failovers, events that should be active in pipelines could be marked as cancelled.
Alarm Misc Fixed Made capitalization of alarm loggers consistent.

OPC-UA

Area Change Type Changelog
Ignition Integration Fixed Fixed OPC tags with Bad quality showing as Unknown in the Designer.
Misc Added Functionality Client OPC scripting functions no longer require the Vision module to be registered in the Designer.

SECS/GEM

Area Change Type Changelog
GEM/SECS Fixed S7F6 messages returning a file as ASCII resulted in incorrect String encoding when the file's bytes were processed by the SECS/GEM module.
GEM/SECS Added Functionality Equipment messages are now recorded in the database via the Store and Forward system, which will prevent message loss if the database connection is temporarily lost.

SFC

Area Change Type Changelog
Engine Fixed Transitions that are true immediately when activated can stop working after several activations.
Engine Fixed Polling expression functions in SFC transitions can lead to unexpected errors in chart execution.
Engine Fixed Error logged for blank cancel expression in Parallel element when "cancel condition" is enabled.

Tag Historian

Area Change Type Changelog
Querying Fixed Race condition in remote dataset streaming randomly preventing all rows from being written.
Querying Fixed Default system name not correctly injected in historical tag path when provider is specified, for example with paths such as: "[DB/.Provider]Tag". If "Tag" exists in multiple providers on the gateway, historical values will be intermingled.
