Mule Runtime 4.1.4 Release Notes

Oct 8, 2018

New Features and Enhancements

Mule Runtime 4.1.4 includes the following enhancements, changes, and fixes:

  • This release is mainly focused in fixing bugs and stability issues.

Changes

Not applicable.

Known Limitations and Workarounds

Issue Description

EE-6372

Mule.bat in Windows set the WRAPPER_WORKING_DIR incorrectly. This produces an error when trying to install the license using a relative path. As a workaround, you need to use the absolute path of the license file.

Upgrade Requirements from 4.1.3 to 4.1.4

Issue Description

MULE-14148

HTTP wire logging now depends on the server/client names to allow more fine grained logging. For example, given an HTTP listener config named A and an HTTP request config named B, HttpMessageLogger.A will show only the listener data while HttpMessageLogger.http.requester.B will only show the requester data. This means log lines will also feature the server/client naming convention.
