Search by issue or merge request number
Someone says "can you look at 412?" and until now the board's search box could only help if 412 happened to be in a title. It searched titles and nothing else.
Type a number now and the board finds cards by number too. The match starts
from the left, the way you'd type it, so 41 finds #41, #412 and #4100, but
not #341. Keep typing and the list narrows.
Merge requests and pull requests count too, written the way your provider writes them:
412finds issue #412, or any card with a linked merge request or pull request numbered 412.#412finds issue #412. On GitHub it also finds pull request #412, because GitHub writes both the same way.!412finds a linked merge request or pull request only, using GitLab's!for merge requests.
The search box's hint shows the form for the board you're on: #issue or !MR
on GitLab, #issue or #PR on GitHub.
As before, search looks at the cards the board has loaded and doesn't read labels or descriptions. A merge request drops off its card once it is merged or closed, so only open ones can be found this way.
