Its headline change alters how setup edits MCP client configuration: when a JSON or JSONC object has repeated members, REA now edits the last member, matching the value clients read. Setup and uninstall also refuse removals that would reactivate a shadowed duplicate.
The release bundles the changes from v6.6.0, which was tagged but not published to npm. Those changes add Kuna as a caller-supplied static-analysis provider; allow reuse of completed analysis for selected JavaScript facts and multiple APK locale tables; and extend Ghidra support to Windows ARM PE targets and explicitly selected raw m68k images. The notes record Kuna 1.833 coverage on Linux, while Windows, PE, and universal Mach-O are unsupported.
The bundled release also documents limits around the new binary-analysis paths: default-analyzer completion, ARM64EC and ARM64X, and Windows-on-Arm hosts are unverified or unsupported in the stated Ghidra scope. The source does not establish general performance gains, npm availability for v6.7.0, or support beyond the listed environments and formats.
