Change log

v0.6.1

2021/03/17

v0.6

2020/11/20

• Adds vectorized, multi-threaded calculation of many shortest path routes at once

• Restores usability of network.plot() by eliminating usage of Matplotlib’s deprecated Basemap toolkit

v0.5.1

2020/08/05

• Fixes a performance regression in network.get_node_ids()

v0.5

2020/07/28

• Adds support for calculating shortest path distances 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

• Makes matplotlib and osmnet dependencies optional

• Revises the documentation and demo notebook

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.
