TO_CSV Compression with dict arguement released in .25.0, but my Pandas .25.3 doesn't reflect source?
Docstring for TO_CSV from my repo

>         compression : str, default 'infer'
            Compression mode among the following possible values: {'infer',
            'gzip', 'bz2', 'zip', 'xz', None}. If 'infer' and `path_or_buf`
            is path-like, then detect compression from the following
            extensions: '.gz', '.bz2', '.zip' or '.xz'. (otherwise no
            compression).

            .. versionchanged:: 0.24.0

               'infer' option added and set to default.

Docstring for TO_CSV from pandas

>         compression : str or dict, default 'infer'
            If str, represents compression mode. If dict, value at 'method' is
            the compression mode. Compression mode may be any of the following
            possible values: {'infer', 'gzip', 'bz2', 'zip', 'xz', None}. If
            compression mode is 'infer' and `path_or_buf` is path-like, then
            detect compression mode from the following extensions: '.gz',
            '.bz2', '.zip' or '.xz'. (otherwise no compression). If dict given
            and mode is 'zip' or inferred as 'zip', other entries passed as
            additional compression options.
            .. versionchanged:: 0.25.0
               May now be a dict with key 'method' as compression mode
               and other entries as additional compression options if
               compression mode is 'zip'.

#### Problem description
Possibly a misunderstaning of documenentation, but based on how it reads I assumed it was released.

TO_CSV has a new compression functionality to accept dictionary with METHOD type and Archive Name, in source repo doc string for TO_CSV says functionality was added to .25.0, but my docstring for TO_CSV doesn't reflect that as shown above.

I'm using a fresh install of Python + Pandas 

#### Expected Output

#### Output of ``pd.show_versions()``
