 ##New features
- * The `@Tag` annotation configuration can now be set differently from the JGiven defaults. [#806](https://github.com/TNG/JGiven/issues/806)
+ * JGiven-JUnit5 now reports its test outcomes back to JUnit5 before the `@After` methods, not after them. This should make it easier to run extensions like ReportPortal alongside JUnit5.

+ * The JGiven maven plugin did not declare itsself as thread-safe, even though it conceptually is. [#829](https://github.com/TNG/JGiven/issues/829) (thanks to Hatzen for pointing it out and fixing it.)
