 - 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)

 - In the big picture, the `main` function constructs an `ApplicationImp` object, which implements the `Application` virtual interface. Almost every component in the application takes an `Application&` parameter in its constructor, typically named `app` and stored as a member variable `app_`. This allows most components to depend on any other component.

 This program allows us to recognize and reward individuals or groups that identify and report bugs. In summary, in order to qualify for a bounty, the bug must be:

 2. **Relevant**. A security issue, posing a danger to user funds, privacy, or the operation of the XRP Ledger.
 3. **Original and previously unknown**. Bugs that are already known and discussed in public do not qualify. Previously reported bugs, even if publicly unknown, are not eligible.
 4. **Specific**. We welcome general security advice or recommendations, but we cannot pay bounties for that.

-
-Install these dependencies:
-
-- [Doxygen](http://www.doxygen.nl): All major platforms have [official binary
-  distributions](http://www.doxygen.nl/download.html#srcbin), or you can
-  build from [source](http://www.doxygen.nl/download.html#srcbin).
-  - MacOS: We recommend installing via Homebrew: `brew install doxygen`.
-    The executable will be installed in `/usr/local/bin` which is already
-    in the default `PATH`.
-
-    If you use the official binary distribution, then you'll need to make
-    Doxygen available to your command line. You can do this by adding
-    a symbolic link from `/usr/local/bin` to the `doxygen` executable. For
-    example,
-
-    ```
-    $ ln -s /Applications/Doxygen.app/Contents/Resources/doxygen /usr/local/bin/doxygen
-    ```
-
-- [PlantUML](http://plantuml.com):
-  1. Install a functioning Java runtime, if you don't already have one.
-  2. Download [`plantuml.jar`](http://sourceforge.net/projects/plantuml/files/plantuml.jar/download).
-
-- [Graphviz](https://www.graphviz.org):
-  - Linux: Install from your package manager.
-  - Windows: Use an [official installer](https://graphviz.gitlab.io/_pages/Download/Download_windows.html).
-  - MacOS: Install via Homebrew: `brew install graphviz`.
-
-## Docker
-
-Instead of installing the above dependencies locally, you can use the official
-build environment Docker image, which has all of them installed already.
-
-1. Install [Docker](https://docs.docker.com/engine/installation/)
-2. Pull the image:
-
-```
-sudo docker pull rippleci/rippled-ci-builder:2944b78d22db

-
-3. Run the image from the project folder:
-
-```
-sudo docker run -v $PWD:/opt/rippled --rm rippleci/rippled-ci-builder:2944b78d22db
