+#### <sub><sup><a name="5160" href="#5160">:link:</a></sup></sub> fix
+
+* Fix misuse of mount options when performing copy-on-write volumes based of
+ other copy-on-write volumes
+
+This case could be faced when making providing inputs and outputs with
+overlapping paths.
+
+* Switch CGO-based Zstd library by a pure go one
+
+Certain payloads could make Concourse return internal errors due to possible
+errors in from the library we used before.
