Scotland will ease its Covid restrictions from Monday (January 24), removing limits on attendance at indoor events.
Nightclubs can reopen from the same date, coinciding with the end of social distancing requirements.
Scotland's Covid certifiaction scheme will be only be mandatory for entry to events of over 1,000 people.
Organisers must check proof of vaccination or a negative lateral flow test for whichever is lower of 1,000 people or half an event's attendees.
The Scottish Government says it stopped short of certifiaction checks at all venues because of the "significant fall" in Covid cases.
Theatres Trust Director Jon Morgan said the restrictions, announced before Christmas, had effectively shut down the majority of theatres in Scotland.
"It will be a huge relief to theatres, artists and audiences that they will soon be able to reopen."
