Can not use sz/rz in iTem2 3.0

Today, I upgrade my iTem2 to 3.0.0, but sz/rz does not work. The config of lrzsz of iTem2 is in here

• iTerm2 version: 3.0.0
• OS version: OSX 10.11.5
• Attach ~/Library/Preferences/com.googlecode.iterm2.plist com.googlecode.iterm2.plist
• Attach a debuglog.txt

How can I fix the problem?
