## Enhancements

* Cover now uses static mocking when the method under test creates temporary files without deleting them. \[Ref: TG-17368]

## Resolved Issues

* Resolved an issue which caused Cover to produce spurious warnings about inconsistent JDK 8 and Spring Core/Spring Boot versions. \[Ref: TG-18055]
* Resolved an issue which caused Cover to report `Error: unknown`, rather than citing the cause of the problem, while writing tests. \[Ref: TG-17692]
