From ede6a38bcf38bbff56a8e41cb38f69c1532d0697 Mon Sep 17 00:00:00 2001 From: Joshua Joseph Date: Wed, 2 Apr 2014 22:41:39 +0300 Subject: [PATCH] Add "Check for updates" Feature This patch adds a check for updates feature. It connects to http://subsurface.hohndel.org/updatecheck.html to check for any new versions. It then prompts the user with a download link if an update is available. Signed-off-by: Joseph W.
