Releasing a new tidy3d version

This document contains the relevant information to create and publish a new tidy3d version.

Version Information Management

The pyproject.toml is declarative (ie static) and provides information to the packaging tools like PyPi on what version is tidy3d. However, we also have a version.py file so that we can dynamically query tidy3d.__version__ within our python version. These two files need to be kept with the same version. This is achieved by using the bump-my-version utility as described in the following section. These files should not be manually updated.

The configuration of the way the version bumping occurs is described in the pyproject.toml.
