+* `snapshot_accept(test)` now works when the test file name contains `.` (#1669).
 * `local_mock()` and `with_mock()` have been deprecated because they are no longer permitted in R 4.5.
 * `snapshot_review()` now passes `...` on to `shiny::runApp()` (#1928).
 * `expect_named()` now gives more informative errors (#2091).
