Release Notes: This release only rewrites headers if it is safe to do so. The problem with POST together with the -H option has been fixed. Penctl can be used to redirect logging from a file to penlogd dynamically.

Release Notes: The penctl and penlog utilities are now IPv6-compatible. The Automake configuration was updated. A clause was added to the license to explicitly permit distributing binaries linked with the openssl library.
Release Notes: SSL support has been updated.
Release Notes: This release adds a UDP patch from Zen.
