What’s New

  • This connector version requires Mule runtime 4.6.22 or later if you’re using Mule 4.6.x, or Mule runtime 4.9.9 or later if you’re using Mule 4.9.x. If you prefer not to upgrade your Mule runtime, use the connector version released immediately after this one.

javax.naming.NameNotFoundException errors during attribute schema lookups no longer log full stack traces at the WARN level. They are now logged at the DEBUG level, and missing attribute definitions are cached to prevent repeated logging and excessive log growth.

These libraries are upgraded to address reported security vulnerabilities:

  • The com.google.guava:guava library is upgraded to version 33.6.0-jre.

  • The org.slf4j:slf4j-api library is upgraded to version 2.0.18.

  • The org.jetbrains:annotations library is upgraded to version 26.1.0.

W-23129795

3.7.0

June 5, 2026

What’s New

  • You can now use the new Secure SSL Configuration type instead of SSL Configuration type to establish secure connections. The SSL Configuration type was deprecated because it relied on global JVM environment configurations and could not support FIPS-compliant truststore types required under FIPS 140-3 environments.

  • The Secure SSL Configuration type includes the new TLS Context field. Use this field to configure BCFKS truststores and the Bouncy Castle FIPS provider within your Mule applications.

    For more information, refer to Secure SSL Configuration Type.

What’s New

For sources or connection tests prior to deployment, an associated LDAPException message is thrown, ensuring LDAP connections meet advanced security requirements in regulated environments​.
