In your Bitbucket wiki-pages, you have access to data from the issue tracker through a set of wiki macros:
Link to a specific issue
Syntax: <<issue 1>> Result: A link to the issue with id 1 in your repository’s issue tracker.
Link to an issue query
Syntax: <<query ?status=open&status=new All open issues>> Result: A link to all issues with status open or new, where the link text is “All open issues”.
List all issues for a milestone (or show count)
Syntax: <<milestone Beta 1>> Result: A list of issues for milestone “Beta 1″, with links and status for each issue.
List all issues for a query
Syntax: <<issues ?status=open&status=new count|list|compact>> Result: Lists all issues that match the query (status is open or new) in one of two optional styles, or shows the number of issues that match the query.
<<issues ?status=open&status=new list>> shows a full list of open or new issues, in the same layout as the milestone-macro.
<<issues ?status=open&status=new compact>> shows a list of open or new issues, but only the issue id with a link to each issue in the tracker.
Usage example for count: “There are currently <<issues ?status=open&status=new count>> open issues for our project.”
Link to a changeset
Syntax: <<changeset 45cc878df717>> Result: A link to changeset 45cc878df717′s diff-view.
