I saw the Mac wallet is v. 1.3.8. What's the update of this version?
I cannot see the improve of the wallet yet.
From my understanding the build process for the Mac wallet has been improved to generate more stable binaries.
When upgrading wallets, do you create a backup; delete the old wallet version and then import the .dat file into the new wallet after upgrading?
Upgrading the software has nothing to do with your application data, they are in separate folders. You only have to touch the folder that contains the executable files to upgrade the wallet.
