I have a few unconfirmed incoming transactions visible in the wallet from 02. June (5 days old).
Shall I wait more for getting them confirmed or do I need to do fix?

Version of wallet is:

"version" : 1000000,
"protocolversion" : 60001,
"walletversion" : 60000,

update:
"version" : 1010000,
"protocolversion" : 1010000,
"walletversion" : 60000,
"errors" : "WARNING: Displayed transactions may not be correct! You may need to upgrade, or other nodes may need to upgrade."

get new version from git.
