Version 0.3.16 of pagekite.py is available from the downloads page.
This version works around problems in Python's native SSL library which would cause busy TLS tunnels to frequently disconnect (pagekite.py would reconnect automatically, so the main symptom of this was truncated images and file transfers). Users of pyOpenSSL or unencrypted tunnels were not affected.
A few other minor issues were fixed as well, including a regression in the code behind the --all argument.
Upgrading is recommended.
