v2.6.1

Like any good fix to a long standing bug, this is fix part two where I actually fix it totally.

Bug fixes:

• Stop congestion control issues due to packets being chopped in half at higher transfer speeds
• Expose internal SSH structures to read data packet by packet for tun device

Changes:

• Logging for tun has changed to show stats rather than all connections. This should also speed things up
