 # testthat (development version)
 
+* New `snapshot_download_gh()` makes it easy to get snapshots off GitHub and into your local package (#1779).
 * New `local_mocked_s3_method()`, `local_mocked_s4_method()`, and `local_mocked_r6_class()` allow you to mock S3 and S4 methods and R6 classes (#1892, #1916)
 * `expect_snapshot_file(name=)` must have a unique file path. If a snapshot file attempts to be saved with a duplicate `name`, an error will be thrown. (#1592)
 * `test_dir()`, `test_file()`, `test_package()`, `test_check()`, `test_local()`, `source_file()` gain a `shuffle` argument uses `sample()` to randomly reorder the top-level expressions in each test file (#1942). This random reordering surfaces dependencies between tests and code outside of any test, as well as dependencies between tests. This helps you find and eliminate unintentional dependencies.
