Sony has updated the Album application to a new build version 5.4.A.0.12, following on from the last 5.3.A.0.24 build. Judging by the jump in number i.e. 5.3 to 5.4 it should be a reasonable update. Sony says that the update brings support for Android 4.4 KitKat (could Sony be launching KitKat firmware sooner than expected?) as well as PlayMemories Online and other software improvements. You can download the apk here.
Thanks Ben, Jag and all others that sent this in!
