 ## Known problems
 
-**If a project relies on an old version of a package, `cargo-unmaintained` may fail to flag the package as unmaintained (i.e., may produce a false negative).** The following is a sketch of how this can occur.
+- Mercurial repositories are considered "uncloneable" and therefore unmaintained. ([#369])
 
-- The project relies on version 1 of package X, which has no dependencies.
-- Version 2 of package X exists, and adds version 1 of package Y as a dependency.
-- Version 2 of package Y exists.
+- If a package is renamed from X to Y, it is immediately considered unmaintained because the package's repository no longer contains a package named X. ([#441])
 
-Note that version 1 of package X appears maintained, but version 2 does not. Ignoring a few details, version 2 satisfies condition 3 above.

-`cargo-unmaintained` does not, in all cases, check whether the latest version of a package is used, as doing so would be cost prohibitive. A downside of this choice is that false negatives can result.

-Note that false _positives_ should not arise in a corresponding way. Before flagging a package as unmaintained, `cargo-unmaintained` verifies that the package's latest version would be considered unmaintained as well.
