- Signin (4.0.101.0)
- Adds support for OAuth 2.0 token operations in AWS Sign-In, CreateOAuth2TokenWithIAM (client credentials flow), IntrospectOAuth2TokenWithIAM (token inspection), and RevokeOAuth2TokenWithIAM (token revocation).

- BedrockAgentCoreControl (4.0.101.0)
- AgentCore Gateway now supports mapping allowed scopes to separate advertised scopes on the inbound authorizer.
- DSQL (4.0.101.0)
DSQLAuthTokenGeneratornow forces a refresh when the credentials would expire before the generated token, so the token remains valid for its full lifetime (or as close to it as the credentials session duration allows). This applies to credential providers deriving fromRefreshingAWSCredentials(such asAssumeRoleAWSCredentialsandAssumeRoleWithWebIdentityCredentials); EC2 instance profile credentials and static credentials are unaffected. Token generation may now throw if the credentials refresh fails; previously a token could be returned signed with credentials nearing expiration, which the database could reject.
