Is it only me, or consequence of new wallet, that the blockchain is stuck at 17901???

I also see that blokchain stuck at 17901, but in my wallet right now 17943.
A hardcoded checkpoint has been implemented at 17901.
Just sit tight - the new wallet is currently being tested. Upon release I must ask all of you to ditch all older versions permanently - including that nasty green wallet. All will be useless upon release of the new wallet.
All signs are positive so far so just sit tight.
We will sit tight Daddy, no prob...

But if had mentioned that before we did, it would have been easier, IMHO...Thnxs for the update
You have literally been told contemporaneously with my receiving the information. If that's not good enough I don't know what is.
