1.2.0

November 12 2025

Added

• The ListUsersFromChannel method now returns a maximum of 1,000 occupants per channel. Previously, it would return all occupants regardless of count. If you have channels with more than 1,000 occupants, you must use pagination (new Limit and Offset parameters) to retrieve the complete list. BREAKING CHANGE.
