Sony Mobile has released a new update to the Album beta application moving the build number from version 7.2.A.0.4 to 7.2.A.0.6. Sony says that changes include a new full screen actionlayer (single tap on image in full screen to show it). In addition, Sony has changed the colour of the app to yellow in the recent app pane (it was white previously). If you want to try the beta, head over to the Google+ Album beta page.
Thanks GianCist!
