v1.3.0-beta0

This update offers numerous significant enhancements to how ActivitySim works, including:

• Removal of ORCA. This new version of ActivitySim does not use ORCA as a dependency, and thus does not rely on ORCA’s global state to manage data. Instead, a new State class is introduced, which encapsulates the current state of a simulation including all data tables. This is a significant change “under the hood”, which may be particularly consequential for model that use “extensions” to the ActivitySim framework. #654
• Pydantic for model settings. In prior versions, model settings were specifies as YAML input files and could contain arbitrary content, both for ActivitySim at a global level as well as for individual components. This update now uses Pydantic to validate settings. #758
• Input checker. This new component allows for configuring checks on the validity of data input files. #753
• Data Type Optimization. A variety of internal data type optimization changes in #782
• BayDAG Contributions in #657
