[Hummingbird Pro] Hummingbird: Page Cache wp_nonce conflict

After the latest update of Hummingbird plugin (2.1.0) I had to disable Page Cache on every site that is featuring wp_nonce in formulars, because all of a sudden Hummingbird will cache and serve static versions of the formulars, therefore the wp_nonce will fail to validate on submission.

How could this happen, and why with major releases like this we are not warned prior of the possible conflicts that there might arise?
