# 2024-07-04

This release includes improvements to the quality of assertions in unit tests written by Cover and resolves issues within Cover Reports.

## Important Notices

### Removals

* **JUnit 4.7-4.10**: Support for JUnit 4.7 through 4.10 has been removed. Please upgrade to JUnit 4.11 or higher.

## Enhancements

* CLI & Reports: Cover now provides a breakdown of manually written and Diffblue Cover written test coverage during `dcover upload`. \[Ref: TG-21683]
* Cover now writes tests which assert on the bytes inside `InputStreams`, `InputStreamReaders` and `BufferedReaders`. \[Ref: TG-20804]

## Resolved Issues

* Resolved an issue which, in some circumstances, caused Cover to report `F009` (Internal error) while writing tests for methods which contain `Map`s which have classes as values. \[Ref: TG-21672]
* Reports: Resolved an issue which, in some circumstances, caused Cover Reports to show `Unexpected Application Error` when loading the home page. \[Ref: TG-21667]
* Resolved an issue which caused Cover to report `F009` (Internal Error) when writing tests for methods with names which are Java keywords. Cover now reports `R088` (Method name is a reserved keyword). \[Ref: TG-21642]

## Known Issues

* Plugin: Cover incorrectly provides a menu option to write tests for a test file. \[Ref: TG-17163]
* CLI & Plugin: Cover may write tests for JUnit 4.10 and lower that do not compile due to the use of `assertNotEquals`. \[Ref: TG-17605]
* Cover supports Open JDK and Oracle JDK; results with other JDKs may differ due to the variability in their implementations of Java. \[Ref: TG-19345]
* Cover may encounter an `F009: Internal error` while writing tests using Mockito 5. To avoid this issue use an earlier version of Mockito. \[Ref: TG-19610]
