This is just a bugfix release. I have discovered, with the help of Iago Elizechea, a bug in the admob library that made it asking for ads after closing the application. This made OTempo use a bit more network traffic and also a bit more battery than strictly needed.
Fortunatelly, I could solve this issue just by upgrading of the admob library to the latest version. There will not be any visible changes in the application (besides the changelog), but I recommend this upgrade as it will optimize resource usage a little bit.
As always, remember that you can download OTempo using a mobile device, from this link:
