additionalMarketplaces
A Claude Code settings key, read out of the shipped bundle. It has been in the build since v2.1.232, including the newest one read.
What it is
additionalMarketplaces now works as an alias for extraKnownMarketplaces in settings files.
Not Anthropic's. This is the line from the earliest changelog entry here that named it, v2.1.232.
Presence across releases
| Releases | Reading | Declared type | Default |
|---|---|---|---|
| 2.1.245 – 2.1.250 5 releases | never mined | — | — |
| 2.1.232 – 2.1.243 12 releases | in the build | — | — |
A row reading never mined is a release with no archived bundle behind it. Nothing was read out of it, so nothing here says whether the name was in it. A declared type or a default is only ever what that release's own bundle stated.

A reference table page is one whose own table defines this name, and it is where the description above came from. A page that mentions it carries the name somewhere in its text and may say nothing about it at all. Every page carrying it.
Read out of the published npm bundle release by release, and out of Anthropic's own documentation as this site captured it. Nothing on this page is a description anybody here wrote about what the settings key does. All settings keys.
