Removed
- `experimental.shmem` has been removed. Users are encouraged to use tools
such as `ray` for parallel processing and shared memory of pyarrow types.
Added
- `Table.invalid_mask`, `Table.separate_invalid` have been added to allow users to select rows
that fail validation checks.
- `concatenate` now supports passing the `validate` argument, if you want to postpone automatic
validation of a table until after concatenation.
- `Table.drop_duplicates` has been added to remove duplicate rows from a table.
- `Table.unique_indices` has been added to return the indices of the first/last occurrence of each
unique row or subset of columns.
