Version 0.3.19 of pagekite.py is available on the downloads page.
This release fixes a few bugs which could crash Pagekite.py and bring your kites to the ground. It is a recommended upgrade.
(In case you were wondering about 0.3.18, some of the bugs fixed in 0.3.19 were discovered just after we packaged 0.3.18 for release, so we ended up skipping that release.)
Version 0.3.19 marks a change in Pagekite.py development: the 0.3.x releases are now considered "stable" and all new features will go into the up-coming 0.4.x branch.
