During automatic color detection, TERM=dumb now disables colors before COLORTERM, CI, PM2, Next.js runtime, and platform-specific checks; FORCE_COLOR can still explicitly enable colors.
4.4.0release notes
Instances no longer share styles across different color levels, so each instance renders at its own level.
4.3.1release notes
Calling .extend() now changes styles only on the instance on which it is called.
4.3.1release notes
reset prepends the reset code and no longer appends a closing reset; add one explicitly if needed.
4.3.1release notes
strip() now removes OSC 8 hyperlink sequences and returns plain text.
4.3.1release notes
Color detection now gives FORCE_COLOR priority over NO_COLOR, CLI color flags priority over NO_COLOR, FORCE_COLOR priority over --no-color, and lets the last CLI color flag win.
4.3.0release notes

Added a constructor overload that accepts a mock globalThis object for controlled color auto-detection.
4.3.0release notes
Added link(url, text?) for OSC 8 hyperlinks supported by many terminal emulators.
4.3.0release notes

When no colors are detected, the fallback is 16 colors instead of truecolor.
