I noticed a bug that could render a client unable to download new valid blocks from it's peers.
This only happenness in a very specific situation on clients with a (temporary) bad connection receiving multiple valid chains.
Nonetheless, I advise to update your clients asap to guarantee stability of both your daemon and network.
The risk of running into this bug is higher when you are actively mining on your client. Especially when this is combined with slow network connections / slow block synchronising.
So I released a new client (version 1.2.0.3) on Github and updated the link to the Windows binary as well.
For your convenience, here is the link to github:
