There was a post above which suggested a PANS ATM international standard was due in late 2016. CAP 493 SI 2010/04: Procedures and Phraseology concerning Level Restrictions associated with Standard Instrument Departures was withdrawn 13/10/17....but CAP493 4/4/13 it seems is still active.
AFAIK Climb now (not climb unrestricted) is still the correct terminology which cancels intermediate altitudes (UK ICAO exemption).Please advise if I am out of date!
