AppServ 1.9.x release notes

This release occurred on March 3, 2026.

Compatibility

This release is compatible with the Gen5 Riva Meter's firmware 10.5.769 to 10.5.999 (release 3.1).

New features and enhancements

3459404: DI Endpoint Report File (DERF)

DI Endpoint Report File (DERF) is an extensible, concise, CBOR-formatted, and schema-validated report from endpoints. It is created by AppServ and retrieved by EAC through the regular DataV interrogation process. DERF contains supplemental information to the existing AgentDirector context information. This first release contains hardware pop-option information and agent image storage information. This information allows EAC to conduct agent applications’ compatibility checks against V8 blurt availability and manage DI installations based on the size of the agent image storage.

Resolved issues

3731022: Agents intermittently entered fault state because D-Bus could fail when multiple agents started up simultaneously

Resolution: Fixed. D-Bus now handles agent start-up better.

Known issues

AppServ has no known issues at this time.

This release occurred on November 12, 2025.

Compatibility

This release is compatible with the Gen5 Riva Meter's firmware 10.5.769 to 10.5.999 (release 3.1).

Resolved issues

3653055: On polyphase meters, some agents could trigger a memory leak

Resolution: Fixed. Agents can no longer trigger this memory leak.

3608122: Agents had poor performance and packet loss because of internal communication inefficiencies

Resolution: Fixed. The agents (including Consumer Energy Stream (CES)) now have improved inter-communication performance.

Known issues

AppServ has no known issues at this time.

This release occurred on June 30, 2025.

Compatibility

This release is compatible with the Gen5 Riva Meter's firmware 10.5.769 to 10.5.999 (release 3.1).

New features and enhancements

3409403: Meter time zone support

AppServ now supports passing meter time zone information to DI agents, allowing agents to time stamp DI events and alarms with local time before forwarding them to back-office applications.

Resolved issues

3569247: Home Area Network (HAN) data was incorrectly stopping because of missing message responses

Resolution: Fixed. Now, the 2030.5 data server has been updated to not expect metrology data message responses from agents.

Known issues

2856291: When only one agent is installed in either the Itron or Third-Party container and that agent is removed, an unknown event (1245186) is observed in FDM Tools

Workaround: None at this time. The occurrence of this event causes no adverse effects.

This release occurred on April 21, 2025.

Compatibility

This release is compatible with the Gen5 Riva Meter's firmware 10.5.769 to 10.5.999 (release 3.1).

New features and enhancements

3087102: Consolidated SDK API support

AppServ now supports the DI SDK's consolidated API. This gives DI application developers access to all features in a single SDK API.

3341804: Per-country cloud server configuration support

AppServ now supports per-country cloud server configuration. This enables improved localization, compliance with regional regulations, and optimized performance based on geographical needs.

Resolved issues

3341812: Database write times were taking too long.

Resolution: Now, database write performance has been improved by introducing a queue.

3459898: Agents experiencing timeouts because of missing DBus message replies.

Resolution: Now, there are no agent timeouts because the error handling correctly sends responses to all errors.

Known issues

2856291: When only one agent is installed in either the Itron or Third-Party container and that agent is removed, an unknown event (1245186) is observed in FDM Tools

Workaround: None at this time. The occurrence of this event causes no adverse effects.

This release occurred on February 2, 2024.

Compatibility

• Minimum required meter firmware 10.5.769

• Maximum required meter firmware 10.5.999

Resolved issues

Feature configuration (FeatureConfg) for the Data Collection Agent (DCA) was intermittently failing.

Resolution: Now, sending a FeatureConfig for the DCA performs as expected.

Known issues

2856291: When only one agent is installed in either the Itron or Third-Party container and that agent is removed, an unknown event (1245186) is observed in FDM Tools

Workaround: None at this time. The occurrence of this event causes no adverse affects.

This release occurred on December 22, 2023.

Compatibility

• Minimum required meter firmware 10.5.769

• Maximum required meter firmware 10.5.999

New features and enhancements

Support for a new alarm type

Earlier AppServ (and DI) versions supported events and alarms. Events are sent to the head end system during interrogation; alarms are sent to the head end system immediately and then re-sent during interrogation. The new one-shot alarm type is sent to the head end system immediately but is not re-sent during interrogation. The one-shot alarm type supports forthcoming DI applications.

DI Data Cloud

Adds support that allows for an application to transfer metering data to an Itron server using an internet connection and a local Wi-Fi connection.

Data transfer limits

To enable improvements in outcomes applications, AppServ application data transfer limits have been modified.

Known issues

AppServ has no known issues at this time.

This release occurred on January 30, 2023.

Compatibility

• Minimum required meter firmware 10.5.769

• Maximum required meter firmware 10.5.999

New features and enhancements

Removal of DI agents from containers

Agent removal initiated by the EAC is now supported. Enhancements included in an upcoming EAC release will complete the requirement that allow total agent deletion.

AppServ distinguishes DI Developer Key (DDK) meters from production meters.

A DDK meter is manufactured with a script injected into it that allows the meter to run third-party DI agents without licensing requirements. When a developer initially uploads their agent to the EAC an automated process calls the Application Management Service (AMS). The AMS dev signs the agent, giving the agent the DDK signature and allowing the agent to run on the meter. With AppServ's recognition of the DDK meter's dev keys, third-party development is made more convenient by bypassing licensing requirements.

Known issues

AppServ has no known issues at this time.
