From 9961c7f89ce6353609383b16b9fbf3a30e4d8604 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Sun, 4 Sep 2011 11:20:27 -0700 Subject: [PATCH] Remove redundant temperature readings I'm aiming to really differentiate in dive log software by making my XML export files be *clean*, dammit. That means that we don't have random names, we don't have crazy random units, and we don't have redundant information. So when the temperature doesn't change, just don't report it. That's already what "no sample" means, just clean things up.
