Merge Risk: Medium

This is a minor version upgrade and contains no major breaking API changes. However, it is rated as medium risk due to a dependency update and a behavioral change that could impact specific use cases.

Potential Impacts:

  • Custom Transports: An internal dependency, winston-transport, was upgraded. This may cause issues if you have created a custom transport that does not explicitly list winston-transport as a dependency.
  • Behavioral Change: A bug fix in the File transport ensures that it now flushes all data before the finish event is emitted. Applications that may have implicitly relied on the previous, potentially incomplete, write behavior should be verified.

Other changes across this version range consist of bug fixes, security patches, and minor feature enhancements like improved ESM compatibility.

Recommendation:
If you use custom transports or rely on the File transport's write-completion events, you should verify your logging functionality after this upgrade.
