Claude Code 2.1.117 can no longer use 200k context

Claude Code 2.1.117 was just released with an important "fix"

Fixed Opus 4.7 sessions showing inflated /context percentages and autocompacting too early — Claude Code was computing against a 200K context window instead of Opus 4.7's native 1M

Which forces the 1m model with no way to switch to 200k model - saying that Opus 4.7 was always 1m by default and 200k was a wrong context window - what a joke

If you ever want to get back to 200k - you cant unless you force lower compaction threshold -
