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.

Claude Code v2.1.229 12 Aug 2026

Node warnings are suppressed for the rest of the process

You'll notice

Useful3 Signal1

CLI

Node deprecation and experimental warnings stay out of your terminal for the whole run.

What

Previously only warning listeners already registered were removed, so warnings emitted later still printed. The CLI now sets process.noProcessWarnings, keeping Node deprecation and experimental-feature warnings out of your terminal for the whole run.

Evidence

process.noProcessWarnings

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