v0.12.1

This version includes a few additional features and a large amount of documentation improvements.

Deprecations

• pl$polars_info() is moved to polars_info(). pl$polars_info() is deprecated and will be removed in 0.13.0 (#662).

Rust-polars update

• rust-polars is updated to 0.36.2 (#659). Most of the changes from 0.35.x to 0.36.2 were covered in R polars 0.12.0.
  The main change is that pl$Utf8 is replaced by pl$String. pl$Utf8 is an alias and will keep working, but pl$String is now preferred in the documentation and in new code.

What's changed

• New methods $str$reverse(), $str$contains_any(), and $str$replace_many() (#641).
• New methods $rle() and $rle_id() (#648).
• New functions is_polars_df(), is_polars_lf(), is_polars_series() (#658).
• $gather() now accepts negative indexing (#659).

Miscellaneous

• Remove the Makefile in favor of Taskfile.yml. Please use task instead of make as a task runner in the development (#654).
