I'm pleased to announce qcp 0.8.0.

The QUIC Copier (qcp) is an experimental high-performance remote file
copy utility for long-distance internet connections. It is intended as a 
drop-in replacement for scp, with similar security properties.

Major changes since the last version announced to this list (0.1.0):

- 0.8: Support for multi-source transfers and directory recursion
- 0.7: Improved local I/O performance
- 0.6: TLS cipher suite auto-selection based on target hardware
- 0.5: Improved WAN performance and additional tuning options
- 0.4: Support for Linux, OSX and Windows; untested BSD support
- 0.3: Protocol redesign for extensibility (total compatibility break 
with previous versions)

Binaries and Debian packages:

Rust users can install from source with `cargo install --locked qcp`
