Invalidate Markdown Cache

For performance reasons, GitLab caches the HTML version of Markdown text in fields like comments, issue descriptions, and merge request descriptions. These cached versions can become outdated, such as when the external_url configuration option is changed. Links in the cached text would still refer to the old URL.

To avoid this problem, the administrator can invalidate the existing cache by increasing the local_markdown_version setting in application settings. This can be done by changing the application settings through the API:

curl --request PUT --header "PRIVATE-TOKEN: <your_access_token>" "<increased_number>"
