- Closes #21146 - Closes #16721 ## ⚠️ BREAKING ⚠️ This changes the default behavior to now create links for any URL scheme when the user uses the markdown form for links (`[label](URL)`), this doesn't affect the rendering of inline links. To opt-out set the `markdown.CUSTOM_URL_SCHEMES` setting to a list of allowed schemes, all other schemes (except `http` and `https`) won't be allowed. # Before  # After  --------- Signed-off-by: Yarden Shoham <git@yardenshoham.com> Co-authored-by: Giteabot <teabot@gitea.io>
