DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs.

What changed: Added a new longContext survey type to the in-session survey system. The survey fires when Claude Code detects conditions associated with a large or stale context window, and the question text is now customizable per-trigger rather than hardcoded.
Evidence
Long context survey type (search for "long_context" alongside "surveyType")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
