We are in need of some testers for what will become Bitcoin Wallet version 4.22. Changes:

• Approx. 2x speedup when synching the blockchain. We have more speedup in store in a couple of weeks, but this is the first step.
• View all derived wallet addresses in list of "Your addresses". Keys from pre version 4 show up at the bottom of the list under "Old addresses".
• "From addresses" are not shown any more. Nowadays you can distinguish payments by their "to address".

Note this is alpha software. Use at your own risk.
