## Enhancements

* Reports: Cover Reports now allows projects to be managed, migrated and moved between groups, enabling flexible organization of data. \[Ref: TG-20953]
* CLI: The `--disable-mock-inputs`, `--existing-coverage`, `--max-class-length`, `--merge`, `--skip-if-service-out-of-resources`, and `--skip-validation` arguments have been hidden in Cover CLI. These remain valid but may be removed in future releases. \[Ref: TG-20910]
* CLI: The `--output-comments` and `--spring-configuration` arguments have been added to Cover CLI and are also documented in the Commands & Arguments topic. \[Ref: TG-20883]
* Cover: Diffblue Cover now supports Mockito 5.10.0. \[Ref: TG-20842]
* Plugin: SSO options are now available for verifying Cover Plugin Community Edition. \[Ref: TG-20757]
* Cover: A performance improvement has been applied to Diffblue Cover for the processing of XML project configuration files. \[Ref: TG-20747]
* Cover: Diffblue Cover now writes tests which use arguments of Jackson annotated types for methods which serialize objects using `ObjectMapper.writeValueAsString` \[Ref: TG-20728]
* Cover: Diffblue Cover now writes tests which use improved JSON strings as input arguments for methods which deserialize strings using `ObjectMapper.readValue` \[Ref: TG-20717]
* Cover: Diffblue Cover now supports writing tests for Kafka Producers in a Spring Context. \[Ref: TG-20687]
* Cover: Cover CLI now automatically detects the project name from the build system and uses this for Cover Reports. Cover CLI's `--project` option has been deprecated. \[Ref: TG-20673]
* CLI: The syntax for `--mock`, `--mock-static`, `--mock-construction`, and `--exclude` has changed - multiple values must be provided as a comma-separated list. This command line change may also impact your argument files, scripts, pipelines, etc. \[Ref: TG-19173]

## Resolved Issues

* Reports: Resolved a minor navigation issue in Cover Reports which required a double-click to select the Map tab. \[Ref: TG-20867]
* CLI: Resolved an issue which, under some circumstances, caused Cover CLI to fail with `E011: Failed to run a simple example test` when Cover Optimize is enabled. \[Ref: TG-20505]
* Cover: Resolved an issue which under some circumstances caused Diffblue Cover to write tests for modules that only contain test code. \[Ref: TG-20443]

## Known Issues

* Plugin: Cover Plugin incorrectly gives the option to write tests for a test file using the menu option, while in the IDE editor. \[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]
