From f435b0d272c8ef55148fd4dc03a9fe6670360f8b Mon Sep 17 00:00:00 2001 From: John Blackbourn Date: Thu, 24 Aug 2023 16:53:15 +0000 Subject: [PATCH] Media: Add a filter to the `get_available_post_mime_types()` function to allow overriding its database query. This introduces the `get_available_post_mime_types` filter so this query can be skipped or cached by plugins.
