OpenAVC v0.38.0 - Changelog

This release adds Report a problem to device pages, a Programmer password reset for every install type, and a message when a Remote Access session ends. Discovery scans no longer connect to ports in use by connected project devices.

Programmer

New Report a problem link on device pages: under the device name, on the Offline banner, and after a failed command. It sends the OpenAVC team the device's settings (passwords hidden), address, recent messages, log lines and driver file. The dialog shows the report's contents before sending, and Download saves a copy instead. No cloud account or pairing needed.
New Send to OpenAVC button on the Device Audit's last step, next to Download report.
New Forgot your password? link on the sign-in screen, with the steps to reset the Programmer login: Reset Programmer Password in the Windows tray or Mac menu bar, a file named openavc-reset-password on a Raspberry Pi's SD card boot partition, or a file named reset-programmer-password in the data folder on Linux and Docker. The reset clears the username, password and API key, and new ones are set at the next sign-in.
Windows: the OpenAVC Programmer and OpenAVC Panel shortcuts now open on the port set in Settings > Network. New OpenAVC Tray Start menu entry restarts the tray icon after Quit.
Driver Builder: importing a YAML file with the ID of an installed driver now shows Update Driver, Import a Copy and Cancel. Update Driver replaces the installed driver and reconnects its devices with their settings kept.
Smaller fixes: clicking a device tile on the Dashboard opens that device; Browse Community shows a connection error with Retry when the driver library can't be reached; Set Variable on a Stream Deck key, dial or touch zone lists only variables; removed the Panel Access card's instruction to close a Remote Programming session before opening Remote Panel.

Device control and drivers

A command parameter left out of a script, a REST call or an AI assistant command is now sent with the driver's default value. A required parameter left out is still refused.
A device that sends a login prompt while its Password setting is blank now shows offline with "The device asks for a sign-in, and the Password setting is blank." Devices whose driver skips the login when no password is set can take up to 2.5 seconds longer to connect over TCP.
Fixed: a standby command sent during polling could wake the device again.
Driver authors: new then_query: on response rules, a list of queries sent as soon as the rule matches. Use it for a device that reports that something changed but not the new value. In the Driver Builder it is the Then Query list on each text rule. Drivers using it still install and run on earlier releases.
Driver authors: a liveness probe is now paused while polling is paused by the device's state. Earlier releases send it in every state, so a driver with a state-paused poll needs min_platform_version 0.38.0 to add one. Python drivers override _liveness_held().
Driver authors: a tcp_probe is sent to a port with a login prompt only when its expect matches the prompt. New ctx.hold_port for discovery companions.
Driver authors: new Connections section on each simulated TCP device, for simulating a device that accepts one control connection at a time. Drivers can set it with simulator.single_client, also on the Driver Builder's Simulation tab. python -m openavc.simulator.validate no longer reports a prompt after a reply as an error.

Discovery

Scans no longer connect to ports in use by connected project devices. Those devices are identified by their project driver, and displays and projectors that accept one control connection at a time stay connected during a scan.
Probes are sent to each port one at a time. A port with a login prompt is sent only the probes written for that prompt.
New Probes line on each Discovery card: for each port, whether it was in use, had a login prompt, and how many probes connected or read its greeting.
Test Connection on a connected device reports the existing connection instead of opening a second one. The Device Audit's network check uses the same rules as a scan.
Fixed: a device advertising a 169.254 address next to its real one showed as two cards.

Cloud

When a Remote Access session is closed in the portal or times out, the Programmer and panel now show "This remote session has ended. Open it again from the portal."
Fixed: files over 10 MB, such as large asset library images or a project export, failed to load through Remote Access.
The AI assistant's connection test and the cloud port diagnostics show a port held by a connected device as in use by that device. The AI's raw command test is refused on that port.

Plugins

When a plugin fails to start, the AI assistant shows the plugin's error only if the plugin raised PluginRefusal (new in 0.38.0). For any other start-up error, the reply refers to the Programmer's Log.

IT and security

Send to OpenAVC uploads the report to https://cloud.openavc.com/api/v1/reports, from paired and unpaired systems. Nothing is sent without pressing it. If the OpenAVC server can't reach that address, the browser uploads the same file. Added to the Network & Security Cut Sheet.

Updating

Project format stays at 0.16.0, so a project saved on this version opens on v0.37.2.
