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.

Plugins

Marketplace install summaries now separate plugins you disabled from ones that ship disabled by default.

What

After installing from a marketplace, the summary separates plugins you disabled from plugins that ship disabled.

Details

the install result adds installedDisabledByDefault next to the existing installedDisabled
the UI consumes the new field to split the two cases in its output

Evidence

installedDisabledByDefault

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