The ENVy of all other releases

Mostly updates to Traceback rendering, to add support for features introduced in Python3.11

We also have a new env var that I am proposing to become a standard. TTY_COMPATIBLE=1 tells Rich to write ansi-escape sequences even if it detects it is not writing to a terminal. This is intended for use with GitHub Actions / CI, which can interpret escape sequences, but aren't a terminal.

There is also a change to how NO_COLOR and FORCE_COLOR are interpreted, which is the reason for the major version bump.

• Added env var TTY_COMPATIBLE to override auto-detection of TTY support (See console.rst for details). #3675

The so long Python 3.7 release

This version adds support for fine-grained information in tracebacks. In other words, it will highlight columns in tracebacks (for supported Python versions). Here's an example:

This version also drops support for Python 3.7, which has long since reached its EOL. If you are stuck on Python3.7 for any reason, you will not be able to upgrade to this version, but nothing should break.

See below for other changes in this release.
