DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Replaying a stored session no longer shows blank assistant messages for empty command output.

Anonymous. No account, no email.
What
When a stored session is streamed back, a local command whose output is blank once trimmed now produces nothing instead of an empty assistant message. Compact summaries are also now treated as synthetic entries, matching how meta and transcript-only entries are handled.
Evidence

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
