Change log

v0.5.1

2020/08/05

  • Fixes a performance bug in network.get_node_ids()

v0.5

2020/07/28

  • Adds support for calculating shortest path lengths between arbitrary origins and destinations, with vectorization and multi-threading

  • Restores alternate names for aggregation types, which were inadvertently removed in v0.4

  • Fixes a bug with matplotlib backends

  • Improves compilation in MacOS 10.15 Catalina

  • Eliminates the scikit-learn dependency

  • Makes matplotlib and osmnet dependencies optional

v0.4.4

2019/9/4

  • Restores support for pre-C++11 compilers.

v0.4.3

2019/8/28

  • Improved compiler support.

v0.4.2

2019/8/8

  • Speed of network aggregations is improved.

  • Support for aggregating integer values is restored.

  • Thread count and contraction hierarchy status messages are restored.

  • Code written for v0.3 will continue to run, now raising deprecation warnings instead of errors.

  • Compilation improvements for Mac.

v0.4.1

2018/7/30

  • Documentation fixes.

  • Replaced uses of std::map::at() since it’s not supported in pre-C++11 compilers.

  • Replaced initialization lists due to the same reason as above.

v0.4

2017/6/27

  • Major rewrite of the layer between Python and C++, which was previously written using the numpy C++ API, and now is written in cython.

  • The C++ that remains has been cleaned up a bit and formatted.

  • The major functionality change is that global memory is no longer used, so reserve_num_graphs no longer needs to be called and Network objects can be created and destroyed at the user’s pleasure.

  • The change in global memory made the calls to init_pois no longer necessary. Then, that method has been removed and the max_items and max_distance parameters were relocated in the set_pois call.

  • The nearest neighbor queries are now resolved with Scipy instead of libANN. That removed additional global memory.

v0.3

2017/4/5

  • Python 3 compatibility.

  • The “network.nearest_pois()” method can now return the labels of the pois rather than just the distances

  • OSM data loading is now done via the osmnet package.

  • Changes to support multiple graphs.

  • Added reindex functions.

  • Updated documentation.

  • Switched code style checker in Travis CI to “pycodestyle”, which has replaced the “pep8” package.
