Hi,

one of my Qt projects required an autoupdate mechanism and I didn’t find a convincing one, so I created my own. Maybe you’ll find it useful or even contribute:

Fervor is a simple, multiplatform (Qt-based) application autoupdater, inspired by Sparkle.

Features:

  • Multiplaform (works / should work on Windows, Mac OS X, Linux, …).
  • Checks for updates both automatically and manually.
  • Displays release notes.
  • Updates might be skipped or installed later.
  • Backwards compatible with Sparkle (can use the very same appcast RSS).
  • BSD license.
It’s not so much an autoupdate library at the moment (it only shows a link to the user with an update, and the user has to install it him/herself), but it does the job.

Check it out: Fervor at GitHub. There are some screenshots too.
