+### v2.0.0 (prerelease)

-_22 June 2021_
+_This release is currently in prerelease. The below release notes will be condensed into a single entry when we do a final release._
+
+_v2.0.0a1 (1 Jun 2021)_
+
+- 🌟 Added the ability to test building wheels on CPython 3.10! Because CPython 3.10 is in beta, these wheels should not be distributed, because they might not be compatible with the final release, but it's available to build for testing purposes. Use the flag [`--prerelease-pythons` or `CIBW_PRERELEASE_PYTHONS`](https://cibuildwheel.readthedocs.io/en/latest/options/#prerelease-pythons) to test. (#675)
+- ✨ Added the ability to build CPython 3.8 wheels on Apple Silicon. (#704)
+- 🛠 Update to the latest build dependencies, including auditwheel 4. (#633)
+- 🛠 Use the unified pypa/manylinux images to build PyPy (#671)
+- ⚠️ Removed support for building Python 2.7 and Python 3.5 wheels, for both CPython and PyPy. If you still need to build on these versions, please use the latest v1.x version. (#596)

- ✨ Adds support building universal2/arm64 wheels on Python 3.8.

+
+Most developer tasks have a nox interface. This allows you to very simply run tasks without worrying about setting up a development environment (as shown below). This is a slower than setting up a development environment and reusing it, but has the (important) benefit of being highly reproducible; an earlier run does not affect a current run, or anything else on your machine.

+Install [nox](https://nox.thea.codes); homebrew is recommend on macOS, otherwise, pipx is a great choice - in fact, you can use `pipx run nox` and avoid installing completely.

+nox -s lint          # Run the linters (default)
+nox -s tests         # Run the tests   (default)
+nox -s docs -- serve # Build and serve the documentation
+nox -s build         # Make SDist and wheel
+```
+
+More advanced users can run the update scripts. `update_pins` should work directly, but `update_constraints` needs all versions of Python installed. If you don't want to do that locally, a fast way to run it to use docker to run nox:
+
+```console
+docker run --rm -itv $PWD:/src -w /src quay.io/pypa/manylinux_2_24_x86_64:latest pipx run nox -s update_constraints

 However, if only C++17 compiler and standard template library (STL) features are used (not needing a C++17 runtime) it might be possible to set `MACOSX_DEPLOYMENT_TARGET` to a lower value, such as `"10.9"`. To find out if this is the case, try compiling and running with a lower `MACOSX_DEPLOYMENT_TARGET`: if C++17 features are used that require a more recent deployment target, building the wheel should fail.

 For more details see https://en.cppreference.com/w/cpp/compiler_support, https://en.wikipedia.org/wiki/Xcode, and https://xcodereleases.com/: Xcode 10 needs macOS 10.13 and Xcode 11 needs macOS 10.14.
-
-## Windows and Python 2.7
-
-In previous years, Microsoft distributed a compiler toolchain called 'Visual C++ for Python 2.7', which was a distribution of MSVC 2008 that was created to make it easier to build Python 2.7 extensions on Windows, because it was fully compatible with the toolchain that built Python 2.7.
-
-This toolchain does not support modern C++ standards (i.e., C++11 and later). And it is hard to find this toolchain these days, since Microsoft removed the download for the required Visual Studio 2008 needed to build a native extension in April, 2021. So, by default, cibuildwheel does not attempt to build Python 2.7 extensions on Windows.
-
-There is an optional workaround, though: the pybind11 project argues and shows that it is [possible to compile Python 2.7 extension with a newer compiler](https://pybind11.readthedocs.io/en/stable/faq.html#working-with-ancient-visual-studio-2008-builds-on-windows) and has an example project showing how to do this: https://github.com/pybind/python_example. The main catch is that a user might need to install [a newer "Microsoft Visual C++ Redistributable"](https://support.microsoft.com/en-us/help/2977003/the-latest-supported-visual-c-downloads), since the newer C++ standard library's binaries are not included by default with the Python 2.7 installation.
-
-Forcing `distutils` or `setuptools` to use a more recent version of MSVC that supports modern C++ can be done in the following way:
-
-1. Set the environment variables `DISTUTILS_USE_SDK=1` and `MSSdk=1`. These two environment variables will tell `distutils`/`setuptools` to not search and set up a build environment that uses Visual C++ for Python 2.7 (aka. MSVC 9).
-2. Set up the build Visual Studio build environment you want to use, making sure that e.g. `PATH` contains `cl`, `link`, etc.
-    - Usually, this can be done through `vcvarsall.bat x86` or `vcvarsall.bat x64`. The exact location of this file depends on the installation, but the default path for VS 2019 Community (e.g. used in AppVeyor's `Visual Studio 2019` image) is `C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Auxiliary\Build\vcvarsall.bat`. **Note**: `vcvarsall.bat` changes the environment variables, so this cannot be run in a subprocess/subshell and consequently running `vsvarsall.bat` in `CIBW_BEFORE_BUILD` does not have any effect.
-    - In Azure Pipelines, [a `VSBuild` task is available](https://docs.microsoft.com/en-us/azure/devops/pipelines/tasks/build/visual-studio-build)
-    - In GitHub Actions, the default shell is powershell, so you'll need to use `shell: cmd` to source a `.bat` file, and the directory is `"C:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise\VC\Auxiliary\Build\vcvarsall.bat"`. Or you can use an action, such as the [`ilammy/msvc-dev-cmd@v1`](https://github.com/ilammy/msvc-dev-cmd) action to setup the environment (see example below).
-3. Next, call `cibuildwheel`. Unfortunately, MSVC has separate toolchains for compiling 32-bit and 64-bit, so you will need to run `cibuildwheel` twice: once with `CIBW_BUILD=*-win32` after setting up the `x86` build environment, and once with `CIBW_BUILD=*-win_amd64` in a `x64` environment (see previous step).

-### Windows and Python 2.7
-
-Building 2.7 extensions on Windows is difficult, because the VS 2008 compiler that was used for the original Python compilation was discontinued in 2018, and has since been removed from Microsoft's downloads. Most people choose to not build Windows 2.7 wheels, or to override the compiler to something more modern.
-
-To override, you need to have a modern compiler toolchain activated, and set `DISTUTILS_USE_SDK=1` and `MSSdk=1`. For example, on GitHub Actions, you would add these steps:
-
-```yaml
-    - name: Prepare compiler environment for Windows
-      if: runner.os == 'Windows'
-      uses: ilammy/msvc-dev-cmd@v1
-      with:
-        arch: x64
-
-    - name: Set Windows environment variables
-      if: runner.os == 'Windows'
-      shell: bash
-      run: |
-        echo "DISTUTILS_USE_SDK=1" >> $GITHUB_ENV
-        echo "MSSdk=1" >> $GITHUB_ENV
-
-    # invoke cibuildwheel...
-```
-
-cibuildwheel will not try to build 2.7 on Windows unless it detects that the above two variables are set. Note that changing to a more modern compiler will mean your wheel picks up a runtime dependency to a different [Visual C++ Redistributable][]. You also need to be [a bit careful][] in designing your extension; some major binding tools like pybind11 do this for you.

-Visual Studio and MSVC link the compiled binary wheels to the Microsoft Visual C++ Runtime. Normally, these are included with Python, but when compiling with a newer version of Visual Studio, it is possible users will run into problems on systems that do not have these runtime libraries installed. The solution is to ask users to download the corresponding Visual C++ Redistributable from the [Microsoft website](https://support.microsoft.com/en-us/help/2977003/the-latest-supported-visual-c-downloads) and install it. Since a Python installation normally includes these VC++ Redistributable files for [the version of the MSVC compiler used to compile Python](https://wiki.python.org/moin/WindowsCompilers), this is typically only a problem when compiling a Python 2.7 C extension with a newer compiler, e.g. to support a modern C++ standard (see [the section on modern C++ standards for Python 2.7](cpp_standards.md#windows-and-python-27) for more details).

 Additionally, Visual Studio 2019 started linking to an even newer DLL, `VCRUNTIME140_1.dll`, besides the `VCRUNTIME140.dll` that is included with recent Python versions (starting from Python 3.5; see [here](https://wiki.python.org/moin/WindowsCompilers) for more details on the corresponding Visual Studio & MSVC versions used to compile the different Python versions). To avoid this extra dependency on `VCRUNTIME140_1.dll`, the [`/d2FH4-` flag](https://devblogs.microsoft.com/cppblog/making-cpp-exception-handling-smaller-x64/) can be added to the MSVC invocations (check out [this issue](https://github.com/pypa/cibuildwheel/issues/423) for details and references).

+like to test wheel building with these versions, you can enable this flag.
+
+!!! caution
+    This option is provided for testing purposes only. It is not

+    set, such as uploading to PyPI.  Please _do not_ upload these wheels to
+    PyPI, as they are not guaranteed to work with the final Python release.
+    Once Python is ABI stable and enters the release candidate phase, that
+    version of Python will become available without this flag.
+
+Default: Off (0) if Python is available in beta phase. No effect otherwise.
