-## Building for 32-bit Windows
-
-To build executables for Windows 32-bit, install the following dependencies:
-
-    sudo apt install g++-mingw-w64-i686 mingw-w64-i686-dev
-
-For Ubuntu Xenial 16.04 and later, including Ubuntu Bionic on the Windows Subsystem for Linux <sup>[2](#footnote2)</sup>:
-
-    sudo update-alternatives --config i686-w64-mingw32-g++  # Set the default mingw32 g++ compiler option to posix.
-    sudo update-alternatives --config i686-w64-mingw32-gcc  # Set the default mingw32 gcc compiler option to posix.
-
-Note that for WSL the Bitcoin ABC source path MUST be somewhere in the default mount file system, for
-example /usr/src/bitcoin-abc, AND not under /mnt/d/.
-This means you cannot use a directory that located directly on the host Windows file system to perform the build.
-
-Acquire the source in the usual way:
-
-    git clone https://github.com/Bitcoin-ABC/bitcoin-abc.git
-
-Then build using:
-
-    PATH=$(echo "$PATH" | sed -e 's/:\/mnt.*//g') # strip out problematic Windows %PATH% imported var
-    cd depends
-    make build-win32
-    cd ..
-    mkdir build
-    cd build
-    cmake -GNinja .. -DCMAKE_TOOLCHAIN_FILE=../cmake/platforms/Win32.cmake -DBUILD_BITCOIN_SEEDER=OFF # seeder not supported in Windows yet

 This release includes the following features and fixes:
+ - The 32 bits Windows target is no longer supported. It will no longer be part
+   of the release shipment. Users that are willing to build for 32 bits Windows
+   should be aware that this will not be tested by the Bitcoin ABC team and be
+   prepared to face issues.
