 ## (Unreleased) rocPRIM 3.4.0 for ROCm 6.4.0
 
 ### Added
+* Added extended tests to `rtest.py`. These tests are extra tests that did not fit the criteria of smoke and regression tests. These tests will take much longer to run relative to smoke and regression tests.
+ * Use `python rtest.py [--emulation|-e|--test|-t]=extended` to run these tests.
 * Added regression tests to `rtest.py`. Regression tests are a subset of tests that caused hardware problems for past emulation environments.
   * Can be run with `python rtest.py [--emulation|-e|--test|-t]=regression`
 * Added the parallel `find_first_of` device function with autotuned configurations, this function is similar to `std::find_first_of`, it searches for the first occurrence of any of the provided elements.
