# 2024-03-02

This release improves test writing for methods utilizing Kafka Consumers and those returning Mono or Flux sequences. Additionally, Cover Reports now shows an overview of project coverage and a list of recently viewed projects. See the full Release Notes below for details of all enhancements and resolved issues covered by this release.

## Enhancements

* Cover: Diffblue Cover now writes tests using `isA` and `isNull` argument matchers as part of verify statements, replacing the use of `any`. This does not affect argument matchers for primitives, Strings and enums which use `eq`. \[Ref: TG-20821]
* Reports: Cover Reports now provides a project coverage summary table on the Overview tab. \[Ref: TG-20694]
* Cover: Diffblue Cover now writes tests for methods which use a Kafka Consumer by using a `MockConsumer`. \[Ref: TG-20637]
* Cover: Diffblue Cover now writes tests which use Project Reactor's `StepVerifier` for methods that return `Mono` and `Flux` sequences. \[Ref: TG-20270]
* Reports: Cover Reports now provides a list of recently viewed projects in the main navigation menu. \[Ref: TG-19630]

## Resolved Issues

* Reports: Resolved an issue, in the administrator view, which prevented moving a project group to the root of the hierarchy. \[Ref: TG-21015]
* Plugin: Resolved a cosmetic issue which caused a scroll bar to appear on the 'Community Edition license created' screen when IntelliJ's zoom was set higher than 100%. \[Ref: TG-20942]

## Known Issues

* Plugin: Cover Plugin incorrectly provides a menu option to write tests for a test file. \[Ref: TG-17163]
* Cover: Diffblue Cover may produce tests for JUnit 4.10 and lower that do not compile due to the use of `assertNotEquals`. \[Ref: TG-17605]
* Cover: Diffblue 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: Cover may encounter an `F009: Internal error` while writing tests using Mockito 5. To avoid this issue use a version of Mockito earlier than 5. \[Ref: TG-19610]
* Plugin: Under some circumstances, when writing tests at a Class level, Cover will delete an existing getter test. \[Ref: TG-20611]
* Plugin: Under some circumstances, when writing Java tests for Kotlin code, Cover may produce non-compiling tests. \[Ref: TG-20759]
