Scenic

- native support for 3D geometry;
- precise modeling of the shapes of objects (allowing occlusion to be taken into account in visibility checks);
- temporal logic requirements;
- serialization and replay of scenes and simulations;
- a more capable parser, with helpful error messages;
- syntax-highlighting plugins for Sublime Text and Visual Studio Code (which work on Scenic 2 code too);

and many other improvements and fixes.

Scenic 3 is not completely backwards-compatible with Scenic 2, but porting old scenarios to the new syntax should be easy in most cases: see the [documentation](https://scenic-lang.readthedocs.io/en/latest/new.html) for complete details on the changes and advice on porting.

The [documentation](https://scenic-lang.readthedocs.io/en/latest/) also includes revised tutorials explaining the new features in Scenic 3, and the repository contains a variety of new examples demonstrating 3D features as well.

This is a release candidate for Scenic 3, a major update to Scenic adding:

(N.B. Unlike the previous beta release of Scenic 3, this version is once again installable simply using `pip install scenic`, like Scenic 2. Since this is a pre-release, you will need to use `pip install --pre scenic` to get it from PyPI.)

This is a beta release of Scenic 3, a major update to Scenic adding:

Note also that the installation process has changed, with a couple of new dependencies that can't be installed using `pip`. See the [documentation](https://scenic-lang.readthedocs.io/en/latest/) for updated installation instructions and revised tutorials explaining the new features. The repository contains a variety of new examples demonstrating 3D features as well.

This update to Scenic:
* restores support for Python 3.7 (so all versions from 3.7-3.11 are supported);
* adds a built-in simple Newtonian physics simulator for debugging dynamic scenarios without having to install an external simulator;
* adds a `record` statement for recording values from dynamic simulations;
* generalizes the interface to the Webots simulator, which now supports dynamic scenarios;

along with many other minor fixes and improvements. See the [documentation](https://scenic-lang.readthedocs.io/en/latest/new.html) for details.

The `2.x` series of Scenic, providing support for dynamic scenarios, is now out of beta. This release mainly contains bugfixes and minor improvements over `2.0.0b1`, as well as an improved interface to the CARLA simulator contributed by the CARLA team.

This is a beta release of the `2.x` series of Scenic, which adds support for dynamic scenarios, a cross-platform Scenic library for driving scenarios which supports the CARLA and LGSVL simulators, and many other features.
