-After you have a [C++ development environment](./docs/build/environment.md) ready with Git, Python,
-Conan, CMake, and a C++ compiler, you may need to set up your Conan profile.

+These instructions assume a basic familiarity with Conan and CMake.
 
-#### Default profile
-We recommend that you import the provided `conan/profiles/default` profile:
+If you are unfamiliar with Conan, then please read [this crash course](./docs/build/conan.md) or the official [Getting Started][3] walkthrough.
 
-```bash
-conan config install conan/profiles/ -tf $(conan config home)/profiles/
-```
+You'll need at least one Conan profile:
 
-You can check your Conan profile by running:
-
-```bash
-conan profile show
-```
-
-#### Custom profile
-
-If the default profile does not work for you and you do not yet have a Conan
-profile, you can create one by running:
-
-```bash
-conan profile detect
-```
-
-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.
-
-### Patched recipes
-
-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.
-
-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:
-
-```bash
-conan remote add --index 0 xrplf "https://conan.ripplex.io"
-```
-
-Alternatively, you can pull the patched recipes into the repository and use them
-locally:
-
-```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 external/recipes/snappy
-conan export --version 4.0.3 external/recipes/soci
-```
-
-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 profile tweaks
-
-#### Missing compiler version
-
-If you see an error similar to the following after running `conan profile show`:
-
-```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
+   ```
+   conan profile new default --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:
+Update the compiler settings:
 
-```text
-[conf]
-tools.build:compiler_executables={'c':'/usr/bin/gcc','cpp':'/usr/bin/g++'}
+   ```
+   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
 ```
 
-#### 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
+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
 ```
 
-#### 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:
+**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.
 
-```bash
-sed -i.bak -e 's|^compiler\.libcxx=.*$|compiler.libcxx=libstdc++11|' $(conan config home)/profiles/default
+   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
 ```
 
-#### Select architecture and runtime in Windows
+Replace `/usr/bin/gcc` and `/usr/bin/g++` with paths to the desired compilers.
 
-**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.
+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:
 
-Windows developers must also build `rippled` and its dependencies for the x64
-architecture:
+- `conan profile update env.CC=<path> default`
+- `conan profile update env.CXX=<path> default`
 
-```bash
-sed -i.bak -e 's|^arch=.*$|arch=x86_64|' $(conan config home)/profiles/default
-```
+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.
 
-**Windows** developers also must select static runtime:
+   ```
+   # Conan 1.x
+   conan export external/snappy snappy/1.1.10@
+   # Conan 2.x
+   conan export --version 1.1.10 external/snappy
+   ```
 
-```bash
-sed -i.bak -e 's|^compiler\.runtime=.*$|compiler.runtime=static|' $(conan config home)/profiles/default
-```
+Export our [Conan recipe for RocksDB](./external/rocksdb).
+It does not override paths to dependencies when building with Visual Studio.
 
-#### Workaround for CMake 4
+   ```
+   # Conan 1.x
+   conan export external/rocksdb rocksdb/9.7.3@
+   # Conan 2.x
+   conan export --version 9.7.3 external/rocksdb
+   ```
 
-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:
+Export our [Conan recipe for SOCI](./external/soci).
+It patches their CMake to correctly import its dependencies.
 
-```text
-[tool_requires]
-!cmake/*: cmake/[>=3 <4]
-```
+   ```
+   # Conan 1.x
+   conan export external/soci soci/4.0.3@
+   # Conan 2.x
+   conan export --version 4.0.3 external/soci
+   ```
 
-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.
+Export our [Conan recipe for NuDB](./external/nudb).
+It fixes some source files to add missing `#include`s.
 
-#### 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:
-

 1. For conan install, pass `--settings build_type=Debug`
 2. For cmake, pass `-DCMAKE_BUILD_TYPE=Debug`
 
+
+### 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.
+
+```

+
+
+### 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 ...

+ # Rocksdb Change Log
+ > NOTE: Entries for next release do not go here. Follow instructions in `unreleased_history/README.txt`
+ 
++## 9.7.4 (10/31/2024)
++### Bug Fixes
++* Fix a leak of obsolete blob files left open until DB::Close(). This bug was introduced in version 9.4.0.
++
+ ## 9.7.3 (10/16/2024)
+ ### Behavior Changes
