I've released Foolscap-0.1.6, with a few minor bugfixes. The new release can be downloaded from PyPI or directly from the Foolscap home page: http://foolscap.lothar.com/releases/foolscap-0.1.6.tar.gz This release fixes the debian packaging problems that prevented 0.1.5 from being able to create .deb packages. It also fixes a problem with the ChoiceOf constraint, and fixes a couple of problems in the documentation. Foolscap versions 0.1.3 through 0.1.6 (inclusive) are fully wire-compatible with each other. Wire-compatibility-breaking changes are still anticipated in the future. Foolscap is a next-generation RPC/RMI/remote-object protocol, intended to eventually replace Perspective Broker. It offers remote object-capability facilities for Python programs using Twisted's event loop, based upon concepts and patterns from the E language (http://www.erights.org/).
