For those who lost fund after importing a private key, it may be interesting to check whether the owner key and the active key of the account are same.
While creating a new sub-account with current version of client (v0.4.27.2), the owner key and active_key are different by default. In this case, if one dump out the private key of the account and import it into another wallet, only the active key will be imported, as a result, something strange may happen.

Do I have to delete the chain folder and re-sync?

For example,
with v0.4.24, "last_update": "20141208T051234"
Now, "last_update": "2014-12-08T05:12:34"

Have to tweak my scripts..

EDIT:
The "blockchain_get_transaction" API changed as well.

I have a chain server on my Ubuntu box. When working with older versions of windows wallet, I'm able to sync from this chain server, the speed is super fast, like a charm.
Today I managed to install the 0.4.24 wallet on my windows box (finally), however the chain server doesn't work any more.. The windows wallet starts with a successful connection to the chain server, but after some seconds it just disconnect and start to open p2p connections, and syncs slowly.

Any idea?

I found this in p2p.log, wish it helps.

Thanks for help.
