+Subject: [PATCH] Add a granular cache preference thing to attica-kde
+
+Commit 798027fd17ab86eea022e5d269aa86138b28b130
+
+This allows us to explicitly add cache preference to specific calls.
+Usually attica calls want to be very current, but in some cases we can
+assume things aren't going to change often (such as the categories
+call), and we can just use the cached version for those calls.
+
+Fix missing variable name
+Commit 8e164050c594855ee3728678d6d0907a10b28db6
+
+Only trust the expiration date if it's less than 24 hours
