The last Nokia Store client that appeared in Beta Labs almost two months ago, v3.24.053, has made it through testing without further changes (unusually!) and is now being rolled out officially as an auto-prompted update when anyone goes into the Nokia Store on their Symbian (^3/Anna/Belle) device. The main changes for this version, you may remember, were fixes for download queue and purchase bugs.
The previous 'release' version pushed to devices was v3.22.54, which is what you'll probably see if you haven't been experimenting with the Store betas through Nokia Beta Labs. To see if the update is available in your region yet, just go into the Nokia Store client and, if available, you'll see these screens (courtesy SymbianTweet):
