# AWS::Lex::BotVersion
<a name="aws-resource-lex-botversion"></a>

**Note**  
Amazon Lex V2 is the only supported version in CloudFormation.

Specifies a new version of the bot based on the `DRAFT` version. If the `DRAFT` version of this resource hasn't changed since you created the last version, Amazon Lex doesn't create a new version, it returns the last created version.

When you specify the first version of a bot, Amazon Lex sets the version to 1. Subsequent versions increment by 1.
