Names in this entry

envTERM_PROGRAM
Environment reads go through one shared accessor; same variables, same behaviour.
envTERM_PROGRAM_VERSION
Read together with TERM_PROGRAM in several terminal capability checks: an iTerm.app major version of 3 or more gets truecolor output, tmux version 3.4 or later counts as supporting hyperlinks, and a ghostty version of at least 1.2.0 or an iTerm.app version of at least 3.6.6 turns on terminal progress reporting when the progressReporting setting is unset. It is also sent as term_program_version in the tengu_terminal_probe telemetry event.

Is this right?

Other releases about the same thing. Found by shared names or similar wording; neither means one caused the other.
