 ### Bugfixes
 
 - Peer Crawler: The `port` field in `overlay.active[]` now consistently returns an integer instead of a string for outbound peers. [#6318](https://github.com/XRPLF/rippled/pull/6318)
+- `ping`: The `ip` field is no longer returned as an empty string for proxied connections without a forwarded-for header. It is now omitted, consistent with the behavior for identified connections. [#6730](https://github.com/XRPLF/rippled/pull/6730)
+- gRPC `GetLedgerDiff`: Fixed error message that incorrectly said "base ledger not validated" when the desired ledger was not validated. [#6730](https://github.com/XRPLF/rippled/pull/6730)

+## Clang-tidy
+
+Clang-tidy is required to run static analysis checks locally (see [CONTRIBUTING.md](../../CONTRIBUTING.md)).
+It is not required to build the project. Currently this project uses clang-tidy version 21.
+
+### Linux
+
+LLVM 21 is not available in the default Debian 12 (Bookworm) repositories.
+Install it using the official LLVM apt installer:
+
+```
+wget https://apt.llvm.org/llvm.sh
+chmod +x llvm.sh
+sudo ./llvm.sh 21
+sudo apt install --yes clang-tidy-21
+```
+
+Then use `run-clang-tidy-21` when running clang-tidy locally.
+
+### macOS
+
+Install LLVM 21 via Homebrew:
+
+```
+brew install llvm@21
+```
+
+Then use `run-clang-tidy` from the LLVM 21 Homebrew prefix when running clang-tidy locally.
