OpenAVC v0.40.0 - Changelog

Device and plugin logins now stay on the system they were entered on: the project, its backups and exports, and the copies OpenAVC Cloud keeps hold "saved on this system" where each password was. Script code that waits on a slow call no longer holds up the rest of the system, and drivers can receive the UDP packets a device sends. On Windows, an update now brings the tray icon back and no longer leaves behind old update tasks that could reinstall an earlier version.

Logins

Device passwords, every setting a driver marks as a login, plugin logins and the Inter-System key are now kept on the system instead of in the project file. The first start after this update moves them there, after backing up the project.
A saved login shows as Saved on this system with Change in Edit Device, in a plugin's settings, on Video Streams and on the Inter-System page. Enter a device's login again after changing its driver or duplicating it.
A device whose login is not saved on this system, such as on a replacement restored from a backup, says Needs login and asks for it on its page, with Use the driver's default where the driver has one. Restoring a backup, or opening or importing a project, names the devices and plugins that need their login entered. After such a restore, point Present's displays at their new addresses.
Export can include the logins, sealed with a passphrase you choose, and importing that file asks for it. A project backup restored on the same system brings its logins back.
The AI Assistant never reads or sets a login. Enter one on the device's page or in the plugin's settings.
A login written into a stream address is no longer sent to OpenAVC Cloud, and the Inter-System key no longer appears in the log or in reports.
To go back to an earlier version, use Rollback in the Updates view, which puts the logins back first. An older version installed by hand over this one finds no passwords, and its devices with a login cannot sign in.
On Docker, which has no Rollback, run docker compose run --rm openavc --put-back-logins with OpenAVC stopped before changing the image tag to an earlier version. The System Updates guide has the steps.

Programmer

A plain def script handler, timer or function a control calls now runs on its script's own thread, so a time.sleep() or a slow web request holds up that script and nothing else. It still gets 30 seconds, and an async def must still never block.
Fixed: a setting saved right after a plugin starts is kept.

Panel

Fixed: a list whose key pattern holds brackets or parentheses now matches them as typed.

Drivers

Drivers can listen for the UDP packets a device sends to a port set on the device, such as SNMP traps, and simulated devices send them too. The Driver Builder offers it under Push Notifications (UDP Listener).

Cloud

Fixed: a system paired to OpenAVC Cloud without restarting now installs the software updates the cloud sends it.

Windows

Fixed: the OpenAVC icon by the clock now comes back on its own after an update.
Fixed: a scheduled task left by an earlier update could run again after a Windows restart and put that older version back. Updates now remove their task, and this version removes the ones earlier updates left.

Updating

Project format stays at 0.16.0. A project saved on this version opens on v0.39.0 and v0.38.0 without its logins, which stay on this system.
The Docker image can now listen on ports below 1024 with host networking, so Short URLs and devices that send to a low port (SNMP traps on 162) work there.
The one-line Linux install now completes on servers whose Python has no venv package.
