• No track of the bug fixes were kept.

pgRouting 2.0.0 Release Notes¶

To see the issues closed by this release see the Git closed issues for 2.0.0 on Github.

With the release of pgRouting 2.0.0 the library has abandoned backwards compatibility to pgRouting 1.x releases. The main Goals for this release are:

• Major restructuring of pgRouting.
• Standardization of the function naming
• Preparation of the project for future development.

As a result of this effort:

• pgRouting has a simplified structure
• Significant new functionality has being added
• Documentation has being integrated
• Testing has being integrated
• And made it easier for multiple developers to make contributions.

Important Changes

• Graph Analytics - tools for detecting and fixing connection some problems in a graph
• A collection of useful utility functions
• Two new All Pairs Short Path algorithms (pgr_apspJohnson, pgr_apspWarshall)
• Bi-directional Dijkstra and A-star search algorithms (pgr_bdAstar, pgr_bdDijkstra)
• One to many nodes search (pgr_kDijkstra)
• K alternate paths shortest path (pgr_ksp)
• New TSP solver that simplifies the code and the build process (pgr_tsp), dropped “Gaul Library” dependency
• Turn Restricted shortest path (pgr_trsp) that replaces Shooting Star
• Dropped support for Shooting Star
• Built a test infrastructure that is run before major code changes are checked in
• Tested and fixed most all of the outstanding bugs reported against 1.x that existing in the 2.0-dev code base.
• Improved build process for Windows
• Automated testing on Linux and Windows platforms trigger by every commit
• Modular library design
• Compatibility with PostgreSQL 9.1 or newer
• Compatibility with PostGIS 2.0 or newer
• Installs as PostgreSQL EXTENSION
• Return types re factored and unified
• Support for table SCHEMA in function parameters
• Support for st_ PostGIS function prefix
• Added pgr_ prefix to functions and types
• Better documentation: http://docs.pgrouting.org
• shooting_star is discontinued
