 ## Check notes
 
-There is one check note in this version:
+0 errors | 0 warnings | 0 note
 
- File ‘testthat/libs/testthat.so’:
-    Found non-API calls to R: ‘SET_BODY’, ‘SET_CLOENV’, ‘SET_FORMALS’
+## revdepcheck results
 
-The plan is to remove these calls in the next minor release. I have now informed the majority of users that these functions are going away.
+We checked 9992 reverse dependencies, comparing R CMD check results across CRAN and dev versions of this package.
 
-## revdepcheck results
+ * We saw 91 new problems
+ * We failed to check 26 packages
 
-I did not check revdeps since the fixes are minor and should only decrease the number of errors.
+The majority of this failing tests are due to the removal of `with_mock()`/`local_mock()` since they rely on functions no longer exported the R API. I started the process of notifying package maintainers about this in January, and while a substantial number fixed their packages, unforutnately many did. For the remainder of the issues, I prepared pull requests to fix the problems (mostly bugs revealed by stricter testing). You can see my progress at <https://github.com/r-lib/testthat/issues/2243>.
