Proposed functionality

Proposed functions from Steve Woodbridge, (Classified as Convenience by the author.)
- pgr_pointToEdgeNode - convert a point geometry to a vertex_id based on closest edge.
- pgr_flipEdges - flip the edges in an array of geometries so the connect end to end.
- pgr_textToPoints - convert a string of x,y;x,y;… locations into point geometries.
- pgr_pointsToVids - convert an array of point geometries into vertex ids.
- pgr_pointsToDMatrix - Create a distance matrix from an array of points.
- pgr_vidsToDMatrix - Create a distance matrix from an array of vertix_id.
- pgr_vidsToDMatrix - Create a distance matrix from an array of vertix_id.
Added proposed functions from GSoc Projects:
- pgr_vrppdtw
- pgr_vrponedepot

Deprecated functions

pgr_getColumnName
pgr_getTableName
pgr_isColumnCndexed
pgr_isColumnInTable
pgr_quote_ident

pgr_startPoint
pgr_endPoint
pgr_pointToId

No longer supported

Removed the 1.x legacy functions

Bug Fixes

Some bug fixes in other functions

Refactoring Internal Code

A C and C++ library for developer was created
- encapsulates postgreSQL related functions
- encapsulates Boost.Graph graphs
  - Directed Boost.Graph
  - Undirected Boost.graph.
- allow any-integer in the id’s
- allow any-numerical on the cost/reverse_cost columns
Instead of generating many libraries: - All functions are encapsulated in one library - The library has the prefix 2-1-0

pgRouting 2.0.1 Release Notes ¶

Minor bug fixes.

Bug Fixes

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 Release Notes 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: https://docs.pgrouting.org
shooting_star is discontinued
