What's wrong with this entry?
The entire function that registered textDocument/publishDiagnostics notification handlers for MCP-based LSP servers was removed. This was a passive diagnostics feature that tracked and forwarded diagnostics from language servers.
Removed handler (search for "textDocument/publishDiagnostics" in old version) — rK7
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
