 The `network_id` field was added in the `server_info` response in version 1.5.0 (2019), but it is not returned in [reporting mode](https://xrpl.org/rippled-server-modes.html#reporting-mode). However, use of reporting mode is now discouraged, in favor of using [Clio](https://github.com/XRPLF/clio) instead.
 
+## XRP Ledger server version 2.5.0
+
+As of 2025-04-04, version 2.5.0 is in development. You can use a pre-release version by building from source or [using the `nightly` package](https://xrpl.org/docs/infrastructure/installation/install-rippled-on-ubuntu).
+
+### Additions and bugfixes in 2.5.0
+
+- `channel_authorize`: If `signing_support` is not enabled in the config, the RPC is disabled.
+
 ## XRP Ledger server version 2.4.0
 
-### Addition in 2.4
+[Version 2.4.0](https://github.com/XRPLF/rippled/releases/tag/2.4.0) was released on March 4, 2025.
+
+### Additions and bugfixes in 2.4.0
 
 - `ledger_entry`: `state` is added an alias for `ripple_state`.
+- `ledger_entry`: Enables case-insensitive filtering by canonical name in addition to case-sensitive filtering by RPC name.
+- `validators`: Added new field `validator_list_threshold` in response.
+- `simulate`: A new RPC that executes a [dry run of a transaction submission](https://github.com/XRPLF/XRPL-Standards/tree/master/XLS-0069d-simulate#2-rpc-simulate)
+- Signing methods autofill fees better and properly handle transactions that don't have a base fee, and will also autofill the `NetworkID` field.

 - `book_changes`: If the requested ledger version is not available on this node, a `ledgerNotFound` error is returned and the node does not attempt to acquire the ledger from the p2p network (as with other non-admin RPCs).
 
 Admins can still attempt to retrieve old ledgers with the `ledger_request` RPC.

+## XRP Ledger server version 2.0.0
+
+[Version 2.0.0](https://github.com/XRPLF/rippled/releases/tag/2.0.0) was released on Jan 9, 2024. The following additions are non-breaking (because they are purely additive):
 
 - `server_definitions`: A new RPC that generates a `definitions.json`-like output that can be used in XRPL libraries.
 - In `Payment` transactions, `DeliverMax` has been added. This is a replacement for the `Amount` field, which should not be used. Typically, the `delivered_amount` (in transaction metadata) should be used. To ease the transition, `DeliverMax` is present regardless of API version, since adding a field is non-breaking.

+#### Default profile
 
-You'll need at least one Conan profile:
+We recommend that you import the provided `conan/profiles/default` profile:
 
-   ```
-   conan profile new default --detect
-   ```
-
-Update the compiler settings:
-
-   ```
-   conan profile update settings.compiler.cppstd=20 default
-   ```
-
-Configure Conan (1.x only) to use recipe revisions:
-
-   ```
-   conan config set general.revisions_enabled=1
-   ```
-
-**Linux** developers will commonly have a default Conan [profile][] that compiles
-with GCC and links with libstdc++.
-If you are linking with libstdc++ (see profile setting `compiler.libcxx`),
-then you will need to choose the `libstdc++11` ABI:
-
-   ```
-   conan profile update settings.compiler.libcxx=libstdc++11 default
-   ```
-
-
-Ensure inter-operability between `boost::string_view` and `std::string_view` types:
-
-```
-conan profile update 'conf.tools.build:cxxflags+=["-DBOOST_BEAST_USE_STD_STRING_VIEW"]' default
-conan profile update 'env.CXXFLAGS="-DBOOST_BEAST_USE_STD_STRING_VIEW"' default
+```bash
+conan config install conan/profiles/ -tf $(conan config home)/profiles/
 ```
 
-If you have other flags in the `conf.tools.build` or `env.CXXFLAGS` sections, make sure to retain the existing flags and append the new ones. You can check them with:
-```
-conan profile show default
+You can check your Conan profile by running:
+
+```bash
+conan profile show
 ```
 
+#### Custom profile
 
-**Windows** developers may need to use the x64 native build tools.
-An easy way to do that is to run the shortcut "x64 Native Tools Command
-Prompt" for the version of Visual Studio that you have installed.
+If the default profile does not work for you and you do not yet have a Conan
+profile, you can create one by running:
 
-   Windows developers must also build `rippled` and its dependencies for the x64
-   architecture:
-
-   ```
-   conan profile update settings.arch=x86_64 default
-   ```
-
-### Multiple compilers
-
-When `/usr/bin/g++` exists on a platform, it is the default cpp compiler. This
-default works for some users.
-
-However, if this compiler cannot build rippled or its dependencies, then you can
-install another compiler and set Conan and CMake to use it.
-Update the `conf.tools.build:compiler_executables` setting in order to set the correct variables (`CMAKE_<LANG>_COMPILER`) in the
-generated CMake toolchain file.
-For example, on Ubuntu 20, you may have gcc at `/usr/bin/gcc` and g++ at `/usr/bin/g++`; if that is the case, you can select those compilers with:
-```
-conan profile update 'conf.tools.build:compiler_executables={"c": "/usr/bin/gcc", "cpp": "/usr/bin/g++"}' default
+```bash
+conan profile detect
 ```
 
-Replace `/usr/bin/gcc` and `/usr/bin/g++` with paths to the desired compilers.
+You may need to make changes to the profile to suit your environment. You can
+refer to the provided `conan/profiles/default` profile for inspiration, and you
+may also need to apply the required [tweaks](#conan-profile-tweaks) to this
+default profile.
 
-It should choose the compiler for dependencies as well,
-but not all of them have a Conan recipe that respects this setting (yet).
-For the rest, you can set these environment variables.
-Replace `<path>` with paths to the desired compilers:
+### Patched recipes
 
-- `conan profile update env.CC=<path> default`
-- `conan profile update env.CXX=<path> default`
+The recipes in Conan Center occasionally need to be patched for compatibility
+with the latest version of `rippled`. We maintain a fork of the Conan Center
+[here](https://github.com/XRPLF/conan-center-index/) containing the patches.
 
-Export our [Conan recipe for Snappy](./external/snappy).
-It does not explicitly link the C++ standard library,
-which allows you to statically link it with GCC, if you want.
+To ensure our patched recipes are used, you must add our Conan remote at a
+higher index than the default Conan Center remote, so it is consulted first. You
+can do this by running:
 
-   ```
-   # Conan 1.x
-   conan export external/snappy snappy/1.1.10@
-   # Conan 2.x
-   conan export --version 1.1.10 external/snappy
-   ```
+```bash
+conan remote add --index 0 xrplf "https://conan.ripplex.io"
+```
 
-Export our [Conan recipe for RocksDB](./external/rocksdb).
-It does not override paths to dependencies when building with Visual Studio.
+Alternatively, you can pull the patched recipes into the repository and use them
+locally:
 
-   ```
-   # Conan 1.x
-   conan export external/rocksdb rocksdb/6.29.5@
-   # Conan 2.x
-   conan export --version 6.29.5 external/rocksdb
-   ```
+```bash
+cd external
+git init
+git remote add origin git@github.com:XRPLF/conan-center-index.git
+git sparse-checkout init
+git sparse-checkout set recipes/snappy
+git sparse-checkout add recipes/soci
+git fetch origin master
+git checkout master
+conan export --version 1.1.10 recipes/snappy/all
+conan export --version 4.0.3 recipes/soci/all
+rm -rf .git
+```
 
-Export our [Conan recipe for SOCI](./external/soci).
-It patches their CMake to correctly import its dependencies.
+In the case we switch to a newer version of a dependency that still requires a
+patch, it will be necessary for you to pull in the changes and re-export the
+updated dependencies with the newer version. However, if we switch to a newer
+version that no longer requires a patch, no action is required on your part, as
+the new recipe will be automatically pulled from the official Conan Center.
 
-   ```
-   # Conan 1.x
-   conan export external/soci soci/4.0.3@
-   # Conan 2.x
-   conan export --version 4.0.3 external/soci
-   ```
+### Conan profile tweaks
 
-Export our [Conan recipe for NuDB](./external/nudb).
-It fixes some source files to add missing `#include`s.
+#### Missing compiler version
 
+If you see an error similar to the following after running `conan profile show`:
 
-   ```
-   # Conan 1.x
-   conan export external/nudb nudb/2.0.8@
-   # Conan 2.x
-   conan export --version 2.0.8 external/nudb
-   ```
+```bash
+ERROR: Invalid setting '17' is not a valid 'settings.compiler.version' value.
+Possible values are ['5.0', '5.1', '6.0', '6.1', '7.0', '7.3', '8.0', '8.1',
+'9.0', '9.1', '10.0', '11.0', '12.0', '13', '13.0', '13.1', '14', '14.0', '15',
+'15.0', '16', '16.0']
+Read "http://docs.conan.io/2/knowledge/faq.html#error-invalid-setting"
+```
+
+you need to amend the list of compiler versions in
+`$(conan config home)/settings.yml`, by appending the required version number(s)
+to the `version` array specific for your compiler. For example:
+
+```yaml
+apple-clang:
+  version:
+    [
+      "5.0",
+      "5.1",
+      "6.0",
+      "6.1",
+      "7.0",
+      "7.3",
+      "8.0",
+      "8.1",
+      "9.0",
+      "9.1",
+      "10.0",
+      "11.0",
+      "12.0",
+      "13",
+      "13.0",
+      "13.1",
+      "14",
+      "14.0",
+      "15",
+      "15.0",
+      "16",
+      "16.0",
+      "17",
+      "17.0",
+    ]
+```
+
+#### Multiple compilers
+
+If you have multiple compilers installed, make sure to select the one to use in
+your default Conan configuration **before** running `conan profile detect`, by
+setting the `CC` and `CXX` environment variables.
+
+For example, if you are running MacOS and have [homebrew
+LLVM@18](https://formulae.brew.sh/formula/llvm@18), and want to use it as a
+compiler in the new Conan profile:
+
+```bash
+export CC=$(brew --prefix llvm@18)/bin/clang
+export CXX=$(brew --prefix llvm@18)/bin/clang++
+conan profile detect
+```
+
+You should also explicitly set the path to the compiler in the profile file,
+which helps to avoid errors when `CC` and/or `CXX` are set and disagree with the
+selected Conan profile. For example:
+
+```text
+[conf]
+tools.build:compiler_executables={'c':'/usr/bin/gcc','cpp':'/usr/bin/g++'}
+```
+
+#### Multiple profiles
+
+You can manage multiple Conan profiles in the directory
+`$(conan config home)/profiles`, for example renaming `default` to a different
+name and then creating a new `default` profile for a different compiler.
+
+#### Select language
+
+The default profile created by Conan will typically select different C++ dialect
+than C++20 used by this project. You should set `20` in the profile line
+starting with `compiler.cppstd=`. For example:
+
+```bash
+sed -i.bak -e 's|^compiler\.cppstd=.*$|compiler.cppstd=20|' $(conan config home)/profiles/default
+```
+
+#### Select standard library in Linux
+
+**Linux** developers will commonly have a default Conan [profile][] that
+compiles with GCC and links with libstdc++. If you are linking with libstdc++
+(see profile setting `compiler.libcxx`), then you will need to choose the
+`libstdc++11` ABI:
+
+```bash
+sed -i.bak -e 's|^compiler\.libcxx=.*$|compiler.libcxx=libstdc++11|' $(conan config home)/profiles/default
+```
+
+#### Select architecture and runtime in Windows
+
+**Windows** developers may need to use the x64 native build tools. An easy way
+to do that is to run the shortcut "x64 Native Tools Command Prompt" for the
+version of Visual Studio that you have installed.
+
+Windows developers must also build `rippled` and its dependencies for the x64
+architecture:
+
+```bash
+sed -i.bak -e 's|^arch=.*$|arch=x86_64|' $(conan config home)/profiles/default
+```
+
+**Windows** developers also must select static runtime:
+
+```bash
+sed -i.bak -e 's|^compiler\.runtime=.*$|compiler.runtime=static|' $(conan config home)/profiles/default
+```
+
+#### Workaround for CMake 4
+
+If your system CMake is version 4 rather than 3, you may have to configure Conan
+profile to use CMake version 3 for dependencies, by adding the following two
+lines to your profile:
+
+```text
+[tool_requires]
+!cmake/*: cmake/[>=3 <4]
+```
+
+This will force Conan to download and use a locally cached CMake 3 version, and
+is needed because some of the dependencies used by this project do not support
+CMake 4.
+
+#### Clang workaround for grpc
+
+If your compiler is clang, version 19 or later, or apple-clang, version 17 or
+later, you may encounter a compilation error while building the `grpc`
+dependency:
+
+```text
+In file included from .../lib/promise/try_seq.h:26:
+.../lib/promise/detail/basic_seq.h:499:38: error: a template argument list is expected after a name prefixed by the template keyword [-Wmissing-template-arg-list-after-template-kw]
+  499 |                     Traits::template CallSeqFactory(f_, *cur_, std::move(arg)));
+      |                                      ^
+```
+
+The workaround for this error is to add two lines to profile:
+
+```text
+[conf]
+tools.build:cxxflags=['-Wno-missing-template-arg-list-after-template-kw']
+```
+
+#### Workaround for gcc 12
+
+If your compiler is gcc, version 12, and you have enabled `werr` option, you may
+encounter a compilation error such as:
+
+```text
+/usr/include/c++/12/bits/char_traits.h:435:56: error: 'void* __builtin_memcpy(void*, const void*, long unsigned int)' accessing 9223372036854775810 or more bytes at offsets [2, 9223372036854775807] and 1 may overlap up to 9223372036854775813 bytes at offset -3 [-Werror=restrict]

+cc1plus: all warnings being treated as errors
+```
+
+The workaround for this error is to add two lines to your profile:
+
+```text
+[conf]
+tools.build:cxxflags=['-Wno-restrict']
+```
+
+#### Workaround for clang 16
+
+If your compiler is clang, version 16, you may encounter compilation error such
+as:
+
+```text

 ## Troubleshooting
 
-
 ### Conan
 
 After any updates or changes to dependencies, you may need to do the following:
 
 1. Remove your build directory.
-2. Remove the Conan cache:
+2. Remove individual libraries from the Conan cache, e.g.
+
+   ```bash
+   conan remove 'grpc/*'
    ```
-   rm -rf ~/.conan/data
+
+   **or**
+
+   Remove all libraries from Conan cache:
+
+   ```bash
+   conan remove '*'
    ```
+
+3. Re-run [conan export](#patched-recipes) if needed.
 4. Re-run [conan install](#build-and-test).
 
+### `protobuf/port_def.inc` file not found
 
-### no std::result_of
-
-If your compiler version is recent enough to have removed `std::result_of` as
-part of C++20, e.g. Apple Clang 15.0, then you might need to add a preprocessor
-definition to your build.
+If `cmake --build .` results in an error due to a missing a protobuf file, then
+you might have generated CMake files for a different `build_type` than the
+`CMAKE_BUILD_TYPE` you passed to Conan.
 
 ```
-conan profile update 'options.boost:extra_b2_flags="define=BOOST_ASIO_HAS_STD_INVOKE_RESULT"' default
-conan profile update 'env.CFLAGS="-DBOOST_ASIO_HAS_STD_INVOKE_RESULT"' default
-conan profile update 'env.CXXFLAGS="-DBOOST_ASIO_HAS_STD_INVOKE_RESULT"' default
-conan profile update 'conf.tools.build:cflags+=["-DBOOST_ASIO_HAS_STD_INVOKE_RESULT"]' default

+   10 | #include <google/protobuf/port_def.inc>
+      |          ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+1 error generated.
 ```
 
+For example, if you want to build Debug:
 
-### call to 'async_teardown' is ambiguous
-
-If you are compiling with an early version of Clang 16, then you might hit
-a [regression][6] when compiling C++20 that manifests as an [error in a Boost
-header][7]. You can workaround it by adding this preprocessor definition:
-
-```
-conan profile update 'env.CXXFLAGS="-DBOOST_ASIO_DISABLE_CONCEPTS"' default
-conan profile update 'conf.tools.build:cxxflags+=["-DBOOST_ASIO_DISABLE_CONCEPTS"]' default
-```
-
-
-### recompile with -fPIC
-
-If you get a linker error suggesting that you recompile Boost with
-position-independent code, such as:
-
-```
-/usr/bin/ld.gold: error: /home/username/.conan/data/boost/1.77.0/_/_/package/.../lib/libboost_container.a(alloc_lib.o):
-  requires unsupported dynamic reloc 11; recompile with -fPIC
-```
-
-Conan most likely downloaded a bad binary distribution of the dependency.
-This seems to be a [bug][1] in Conan just for Boost 1.77.0 compiled with GCC
-for Linux. The solution is to build the dependency locally by passing
-`--build boost` when calling `conan install`.
-
-```
-conan install --build boost ...
-```
-
+1. For conan install, pass `--settings build_type=Debug`
+2. For cmake, pass `-DCMAKE_BUILD_TYPE=Debug`

 # The XRP Ledger
 
 The [XRP Ledger](https://xrpl.org/) is a decentralized cryptographic ledger powered by a network of peer-to-peer nodes. The XRP Ledger uses a novel Byzantine Fault Tolerant consensus algorithm to settle and record transactions in a secure distributed database without a central operator.
 
 ## XRP
+
 [XRP](https://xrpl.org/xrp.html) is a public, counterparty-free asset native to the XRP Ledger, and is designed to bridge the many different currencies in use worldwide. XRP is traded on the open-market and is available for anyone to access. The XRP Ledger was created in 2012 with a finite supply of 100 billion units of XRP.
 
 ## rippled
+
 The server software that powers the XRP Ledger is called `rippled` and is available in this repository under the permissive [ISC open-source license](LICENSE.md). The `rippled` server software is written primarily in C++ and runs on a variety of platforms. The `rippled` server software can run in several modes depending on its [configuration](https://xrpl.org/rippled-server-modes.html).
 
 If you are interested in running an **API Server** (including a **Full History Server**), take a look at [Clio](https://github.com/XRPLF/clio). (rippled Reporting Mode has been replaced by Clio.)

+- Read [the levelization document](.github/scripts/levelization) to get an idea of the internal dependency graph.
 - 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.
