[[release-notes-5.8.1-junit-platform]]
=== JUnit Platform

==== Deprecations and Breaking Changes

* `@UseTechnicalNames` has been deprecated in favor of the new `@Suite` support which does
  not require the use of technical names. See the warning in
  <<../user-guide/index.adoc#running-tests-junit-platform-runner, Using JUnit 4 to run the
  JUnit Platform>> for details.

==== New Features and Improvements

* `ReflectionSupport.findNestedClasses(..)` is now thread-safe with regard to cycle
  detection.


[[release-notes-5.8.1-junit-jupiter]]
=== JUnit Jupiter

==== Bug Fixes

* `assertLinesMatch()` in `Assertions` no longer fails with a `NoSuchElementException` if
  a limited fast-forward followed by at least one more expected line exceeds the remaining
  actual lines.
* `assertLinesMatch()` in `Assertions` now handles fast-forwards with leading and trailing
  spaces correctly and no longer throws an `IndexOutOfBoundsException`.

==== New Features and Improvements

* `JAVA_18` has been added to the `JRE` enum for use with JRE-based execution conditions.
* CSV content in `@CsvSource` can now be supplied as a _text block_ instead of an array of
  strings. See the
  <<../user-guide/index.adoc#writing-tests-parameterized-tests-sources-CsvSource, User
  Guide>> for details and an example.
* The `ExecutionMode` for the current test or container is now accessible via the
  `ExtensionContext`.
