 * ![Bugfix][badge-bugfix] A bad `repo` argument to `deploydocs` containing a protocol now throws an error instead of being misinterpreted. ([#1531][github-1531], [#1533][github-1533])
 
+* ![Maintenance][badge-maintenance] Documenter is no longer compatible with IOCapture v0.1 and now requires IOCapture v0.2. ([#1549][github-1549])
