I updated and everything seemed to work properly.
As soon as I published price feeds I started missing blocks.

What if the delegate in the round just after me hasn't updated?
When we are required to publish price feeds?
Should we do it for all currencies ?
Not sure if this is related to 0.4.0 delegates vs 0.3.1 but I'm see this. Note that I haven't missed a block because of this. I have not published a feed yet.
Peer 104.131.134.181:51145 disconnected us: You offered us a block that we reject as invalid

hm .. my backup system successfully upgraded and produced blocks .. when switching to the main system with 0.4.0 he missed blocks ... wlthough all seemed fine ..
strange .. looking into ito
//edit: seems I needed to reanble block production
Do not publish price feeds until after hardfork and all clients are upgraded. This is a new operation that is part of the hardfork. All old clients will reject blocks containing publish price feed operation. This is the reason for missed blocks.
Large transaction and block sizes are also part of the hardfork, and could result in missed blocks.
console.log was disabled by default in previous update for security concerns. It can be enabled using --log-commands argument.
Delegates are still free to upgrade but must be aware that there a crashing issue has been identified. Brave delegates can upgrade and run client in a debugger to help us get a stack trace of the crash.
