Versions and licences

Every build of stream-concern belongs to a channel. The channel and the day the build was made are fixed when it is built; Settings ▸ Licence shows both (see Settings › Licence).

Channels

stream-concern is in alpha: every published build is an alpha build. You get it from the download page once your request for the alpha is approved, and each build works for 30 days from its build date.

A build you make yourself from the source is a Development build and never stops.

When an alpha stops

From 3 days before the end, a line at the bottom of the main window says when this alpha stops. On the day it stops, the app opens a window instead of starting:

This alpha expired on 15 November 2026. Download the latest alpha.

Its one button, Download the latest alpha, opens the download page in your browser, and the app quits. Install the new build; your scenes, settings and recordings are kept, because they live in your profile folder, not in the app.

The check works offline. Setting the computer’s clock back does not bring an expired build back: the app remembers the latest day it has seen, and an expiry, in your profile.

Your alpha access link

When your request for the alpha is approved, you get an e-mail with a personal link. Opening it and pressing the button signs you in to the download page; keep the e-mail, the link does not expire. If you lose it, ask for access again on the home page with the same address: the site e-mails your link again. A link stops working only if your access is withdrawn; ask the owner if that happened by mistake.

Licences

A licence is a block of text. The alpha works without one; if you have been given a licence, this is how to install it.

Entering a licence

1. Copy the licence text you were given, all of it.
2. In the app, open Settings ▸ Licence, paste the text into the box under Enter licence…, and press Apply.

The app checks the licence on your computer, without going online. It is kept in your profile folder as licence.token (~/Library/Application Support/stream-concern/ on macOS, %APPDATA%\stream-concern\ on Windows, ~/.config/stream-concern/ on Linux). Remove licence deletes it from this computer.

If a licence cannot be used (it was changed, or it is for a newer version of stream-concern), Settings ▸ Licence says why; the app keeps working.
