Wiki preview URL converting problem [via Markdown]
Current implementation when rendering the preview, thinks relative links are for project repository files.
We are creating a new preview route that will define correct context data to render for wikis instead.
Fixes#2380, #1184
See merge request !3461
When importing members, and user does not have permissions to read
members in a source project, do not leak information about source
project existence. Notifiy user that project has not been found instead.
Fix Raw / Rendered diff producing different results on merge requests
The raw diff endpoint (`merge_requests/####.diff`) produces a diff based on `target_branch` instead of the original branching point. Same is valid for `merge_requests/####.patch`.
Fixes#14680, #3017
