AppServ 1.13.x release notes

This release occurred on March 3, 2026.

Compatibility

This release is compatible with the Gen5 Riva Meter's firmware 10.8.551 to 10.8.999 (release 3.1.1).

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.

3794823: NetMgr agent-facing APIs had intermittent issues

Resolution: Fixed. NetMgr agent-facing APIs now correctly pass responses to agents.

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 10.8.551 to 10.8.999 (release 3.1.1).

New features and enhancements

3653714: Generic Meter Interface (GMI) support for brownfield deployments

DI can now communicate with more legacy devices in a brownfield deployment.

Resolved issues

3402668: DI was not correctly communicating during brownfield deployments

Resolution: Fixed. DI now correctly communicates during brownfield deployments.

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 10.8.551 to 10.8.999 (release 3.1.1).

New features and enhancements

3545930: Brownfield RF peer-to-peer communication support

AppServ now supports peer-to-peer communication over the 900 MHz RF band between DI-capable mesh devices (such as the Gen5 Riva Electricity Meter) and legacy GenX devices (such as the Aclara or L+G Gen5 meters). This capability enables active transformer load and voltage monitoring across networks that combine legacy GenX devices with DI-capable mesh meters.

3537011: High-speed metrology enhancements

AppServ now better supports transferring metrology data at high-speed (32k samples per second) between the data server and the agents.

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. 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 10.8.551 to 10.8.999 (release 3.1.1).

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.
