I find your tone almost accusatory but we've already spoken about this, several times.
It's important to delete the old blockchain so that you're not orphaned so to speak. As I've put security measures in place, if your client is broadcasting the old protocol it will be banned by the new protocol. In this regard it is posible to update the client version, but until you rebuild/rescan your blockchain you won't be able to play with the rest of us.

All (or most, I'm sorry if I missed anyone) of the PMC community have been notified of the intended changes to the swap guidelines some time ago.
Those transactions releasing 100% of swap funds have been rolled back. I already mentioned that I would be making these changes retroactively so that everyone would abide by the new guidelines. Switching back to the old wallet will not circumvent this  

I've been trying to take a moment to make a proper official announcement about it for over a day, but I'm getting distracted by a lot of other work. I also wanted to wait until I had the stable release to make it.

So my apologies if this comes as a surprise.  
Please note, your swap coins are supposed to disappear when you update.
We will be sending them out again over the next little while.
Your wallet might also show some empty transactions. If these bother you, you can rescan it to get rid of them.
