Release Notes: This release adds support for authentication via SSH. DUP will now also secure the establishment of data streams in the system. This release also adds some minor improvements and various bugfixes. Most importantly, IPv6 support was improved, making the code more robust on dual-stack machines.
Release Notes: In addition to fixing various bugs, this release improves the performance of most filters, especially for long lines of input. It also adds support for writing a PID file to dupd, increases the number of file descriptors to 65536 (overriding FD_SETSIZE), fixed various performance issues in dup to dupd communication, and also adds caching of DNS lookups to dupd. The language and network protocol are entirely backwards-compatible. The main changes for this release either improve performance or fix (largely minor) bugs.
