@rajibmitra found another in `pandas/tests/scalar/timestamp/test_unary_ops.py::TestTimestampUnaryOps::test_round_dst_border_nonexistent`, if you could update that too. `pandas/tests/series/test_datetime_values.py::TestSeriesDatetimeValues::test_dt_round_tz_nonexistent` as well and `pandas/tests/test_config.py::TestConfig::test_deprecate_option` @rajibmitra make sure you merge master @jreback merged my master. thanks.   @TomAugspurger  will do those changes in couple of minutes , give me some time. Thanks.  @rajibmitra I'm going to push a few more fixups here. sorry , got busy with other stuff, sure @TomAugspurger  No worries. Merging this on green, since it's failing other builds. lgtm. # [Codecov](https://codecov.io/gh/pandas-dev/pandas/pull/24707?src=pr&el=h1) Report
