 ## Supported Ruby versions
 
-This library is supported on Ruby 3.1+.
+This library is supported on Ruby 3.2+.
 
 Google provides official support for Ruby versions that are actively supported by Ruby Core -- that is, Ruby versions that are either in normal maintenance or in security maintenance, and not end of life. Older versions of Ruby _may_ still work, but are unsupported and not recommended. See https://www.ruby-lang.org/en/downloads/branches/ for details about the Ruby support schedule.
