### Fixed Issues The release addresses these DataWeave issues and incorporates all patch updates from the 2.12.0 DataWeave release through October 2026:
Issue Resolution ID

Memory usage for text/plain output is reduced.

W-20063270

Eagerly materialize executable Weave reader results.

W-23837275

Thread safety is improved when processing Java map values.

W-23661641

DataWeave tooling now reports design-time warnings when Java classes referenced in application/java schemas can’t be found or are inaccessible through JPMS.

W-22797049

DataWeave now filters Java classes in JPMS-unexported packages during Java module resolution, preventing runtime IllegalAccessException failures. This behavior is enabled by default on JDK 17 and later with DataWeave language version 2.13 and later. To keep the previous behavior, set mule.dw.filter_jpms_inaccessible_modules=false.

W-22779527

Cryptographic security warnings and errors now include call stacks.
