LastPass Breach - Security Done Rightish

In today's world it is only a matter of time before a company's data is breached and this time it was LastPass. They said that they discovered the breach on Friday, 6/12/15 and they quickly reported it to users the following Monday, 6/15/15. Nothing has been said to what date the breach actually occurred though.

LastPass has also stated that no encrypted user vaults were taken, nor that any user accounts were accessed. Only account email addresses, password reminders, server per user salts, and authentication hashes were compromised.

This sounds like another terrible breach, right? What are all the LastPass users going to do now?
