Autoupdates

Release channels

Each .json file is a 'release channel':

• preview.json: the user has opted in to this channel, or previously installed a prerelease
• stable.json: the user has only used stable releases

The preview channel usually should point at the latest release, regardless of if it's a prerelease or not; the stable channel should usually point at the latest stable release.

Purpose

This decouples actually making releases from the autoupdates; in particular, this allows:

• full control over which release is used, even if there's bugs in the release selection logic
• control over timing, e.g. announcing new beta releases to Discord before pushing the autoupdate, and pushing new stable releases to the preview channel before the stable channel

Format

These files are in the same format as https://api.github.com/repos/OpenKneeboard/OpenKneeboard/releases, documented at https://docs.github.com/en/rest/releases

Generation

The files can be manually modified, but generation is usually desired:

1. Install PowerShell 6 or above (e.g. from the Microsoft Store)
2. run generate.ps1
3. check git status and git diff to check the changes
4. you may wish to revert stable.json to push a new release only to the prerelease channel
