[14.1.0] - 2025-06-25

Changed

• Removed typing_extensions from runtime dependencies #3763
• Live objects (including Progress) may now be nested #3768

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.
