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.

You can now write additionalMarketplaces and allowedMarketplaces as aliases for the older marketplace settings keys.

What

Settings files can now write additionalMarketplaces for extraKnownMarketplaces and allowedMarketplaces for strictKnownMarketplaces. The alias is folded into the canonical key when settings are read, and if both spellings appear in one file the alias is ignored with a warning.

Details
  • Applied on the normal settings read path, the raw-settings fallback path, and the settings write path, so Claude Code may rewrite an alias to the canonical spelling when it saves.
  • The warning names both keys: keep only the canonical one.
  • The aliases were also added to the list of keys the SDK strips when sanitizing settings, alongside enabledPlugins and extraKnownMarketplaces.
Evidence

are the same setting; keep only, "${e.alias}" and "${e.canonical}" are the same setting; keep only "${e.canonical}"

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