📘

Important Note:

If you are manually updating the OpenLegacy Core version, make sure to also update the following code:

buildSrc/build.gradle.kts

requested.group == "com.fasterxml.jackson.core" -> {
  this.useVersion(jacksonVersion)
}

Change it to:

buildSrc/build.gradle.kts

requested.group == "com.fasterxml.jackson.core" -> {
  if(requested.name != "jackson-annotations") {
    this.useVersion(jacksonVersion)
  }
}

🚀 Enhancements

Improved AS/400 Reverse API COBOL Client Generation

• Added a Linkage Section so the generated client can be called from other COBOL programs.
• Added environment variable support — instead of hardcoding the server URL, users can now specify it using the syntax: ENVVAR:<env-var-name>. The environment variable defines the server URL for the relevant environment, so the client no longer needs to be modified per environment.

🐞 Bug Fixes

• The “Map To...” option can now be used with Flow variables even when no variable has been defined yet.
• Fixed an issue with Project variable mappings — you can now map them correctly again.
• Fixed a problem where flows failed when multiple cloned flows were published.
• The generated OpenAPI specification now correctly includes example values for string collections.
