We pushed a new update  v3.0.2 wallets.
This is a minor, non-mandatory, update. There's a few very minor GUI bug fixes and you can also now see the latest block number when you hover over the Synchronization icon (the icon furthest left on the top right hand of the screen). In addition, it's now possible to copy any of the values in the fields within the Coin Control screen so that you don't have to manually remember and type in the Send screen.

v3.0.1 and v3.0.2 not a mandatory update, and Your can choose to stay with v3.0.0

Latest version v3.0.2 are available for download on Github
