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.

MCP servers declared under a previous workspace root are dropped

MCP

MCP servers declared under a different workspace root are now dropped instead of lingering.

What

A project- or local-scoped MCP server whose declaring location no longer matches the current workspace root is now marked stale and torn down, along with its tools, commands, resources and prompt templates. Previously only removal or a changed config hash retired a server, so one declared in a different workspace root could linger.

Evidence

excludeStalePluginClients: marking stale (declared under a previous workspace root)

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