 Entropy scans can produce a high number of false positives such as git SHAs or md5
 digests. To avoid these false positives, enable ``exclude-entropy-patterns``. Exclusions

 For example, if ``docs/README.md`` contains a git SHA, this would be flagged by entropy.
-To exclude this, add ``docs/.*\.md$::^[a-zA-Z0-9]{40}$`` to ``exclude-entropy-patterns``.

-    As of version 2.9.0, the above specification style has been deprecated, and
-    will be removed in version 3.0. The new style uses a TOML `array of tables`_
-    as shown below.

-    Note that this new syntax is not available on the command line, and must be

-Here is an example of how you might exclude SHA hashes in your docs, as well as
-hashes for GitHub Actions in your workflows:
+To exclude this, add an entry to ``exclude-entropy-patterns`` in the config file.
 
 .. code-block:: toml

     exclude-entropy-patterns = [
         {path-pattern = 'docs/.*\.md$', pattern = '^[a-zA-Z0-9]$', reason = 'exclude all git SHAs in the docs'},
-        {path-pattern = '\.github/workflows/.*\.yml', pattern = 'uses: .*@[a-zA-Z0-9]{40}', reason = 'GitHub Actions'}
     ]
 
 Thanks to the magic of TOML, you could also split these out into their own tables
