+					Pre-release version of Megapixels 2
+
+					Several devices now have better support in the Megapixels 2.x
+					development branch than in the Megapixels legacy branch so this is a
+					release for distributions to be able to package Megapixels for those
+					devices.
+
+					The device support in this release should strictly be a superset of the
+					old Megapixels 1.x releases but not all features are fully functional
+					yet.
+
+					This release depends on libdng 0.2.0 and libmegapixels 0.2.0 to run
+					correctly.
+
+					Thanks to @k.vos, @pavelm, @pastalian for the Megapixels app
+					contributions.
