Version 1.16.0 of the sequoia-openpgp crate fixes some issues in parsing code, which could lead to attempted out-of-bounds accesses that result in crashes due to bounds checks which are included by default in Rust code. This update contains rebuilds of all applications that are based on sequoia-openpgp to address this issue.

Additionally, this update contains an update of the socket2 crate to version 0.5.2, including a compat package for version 0.4 for backwards compatibility.
