 Path4GMNS is an open-source, cross-platform, lightweight, and fast Python path engine for networks encoded in [GMNS](https://github.com/zephyr-data-specs/GMNS). Besides finding static shortest paths for simple analyses, its main functionality is to provide an efficient and flexible framework for column-based (path-based) modeling and applications in transportation (e.g., activity-based demand modeling). Path4GMNS supports, in short,

-v0.9.4 fixes crucial bugs in the simulation module. Any versions prior to v0.9.4 will generate INCORRECT simulation results. Please **update to or install the latest version** and **discard all old versions**.
+v0.9.5 enhances v0.9.4 by taking any arbitrary node id's and zone id's from input files. Previous versions can only take integer values. Note that any versions prior to v0.9.4 will generate INCORRECT simulation results. Please **update to or install the latest version** and **discard all old versions**.
 
 ### Dependency
 The Python modules are written in **Python 3.x**, which is the minimum requirement to explore the most of Path4GMNS. Some of its functions require further run-time support, which we will go through along with the corresponding **[Use Cases](https://path4gmns.readthedocs.io/en/latest/)**.
