This 2.0 release brings a number of major new features:
pgRouting 2.0 is not backwards compatible with the 1.x version. This is a significant overhaul of the whole pgRouting environment and we have renamed all the functions and rationalized the arguments and return types. While this will be a painful migration for 1.x applications, we believe the new functionality, the high quality of the code, and new documentation will make it much easier to grow the product and support it over future releases.
Thank you to all of the users, developers, and supporters of pgRouting. We would like to call out special thanks to CSIS (University of Tokyo), Georepublic, Paragon Corporation, iMaptools.com and to Vicky Vergara for their time and support that really made this release possible. We also had a lot of support from our users testing releases, submitting patches, reporting issues and our apologies for not being able to list everyone by name but we do appreciate everyone's efforts. Enjoy.
The pgRouting Team
