Is this why i'm seeing it randomly just stop for no discernible reason? I've had 2 tasks just hang for 30 minutes since this release with no rhyme or reason

It also removed opus 1m.

Auto-Compact looping continuously would drain tokens rapidly. This could be contributing to the rate limit exhaustion many Max subscribers are seeing.

Update (April 2): v2.1.90 shows significant cache improvement.

Benchmark on the same machine confirms v2.1.90 achieves 86%+ overall cache read and 95-99% in stable sessions — both npm and standalone. If you're still on v2.1.89 or earlier, updating is the most impactful fix.

Disable auto-update after upgrading to pin the working version:

// ~/.claude/settings.json
{ "env": { "DISABLE_AUTOUPDATER": "1" } }

April 3 update: The cache regression (Bugs 1-2) is fixed in v2.1.91. However, systematic proxy testing revealed additional unfixed mechanisms — a 200K tool result budget cap, a client-side false rate limiter (151 synthetic entries found), and silent microcompact clearing (327 events). Anthropic responded on X (Lydia Hallie) acknowledging peak-hour tightening but stating "none were over-charging you" — our measured data shows mechanisms their statement does not cover.
