## 1.4.0

**December 20, 2025**

### What’s New

- FIPS 140-3 Compliance Support:  
  This release introduces comprehensive FIPS 140-3 compliance support, including:

  - Automatic FIPS mode detection via the `mule.security.model` system property

  - Smart BouncyCastle FIPS (BCFIPS) security provider registration with safety controls

  - Support for FIPS-certified Snowflake JDBC driver

  - Prevention of unauthorized JVM security configuration modifications in FIPS mode

  - Two configuration options: Configure BCFIPS in `java.security` (recommended) or enable
    auto-registration with explicit authorization

- TLS 1.3 Support:  
  Enhanced security with modern TLS 1.3 protocol support for Snowflake connections

- Security Provider Management:  
  Improved security provider registration logic with validation-first approach to prevent conflicts
  in regulated environments

For detailed FIPS configuration instructions, see
[Configuring FIPS 140-3 for Snowflake Connector](https://docs.mulesoft.com/snowflake-connector/latest/snowflake-connector-fips-config).
