Hi,

I like to inform you, that the official Windows builds of PHP 7.4 and
master (available from windows.php.net; currently only snapshot builds,
of course) are done with Visual Studio 2019.  While it is still possible
to build these PHP versions with Visual Studio 2017, this is no longer
tested.

This also means a small but important change, namely that we are no
longer using the "vc" prefix (e.g. "vc14", "vc15") to refer to *new*
Visual Studio versions, but rather "vs" (i.e. "vs16").  The detailed
reasoning is explained in the post titled "Visual Studio 2019
Builds"[1].  Recent beta versions of the PHP SDK are supposed to fully
support this naming change already (and particularly the renaming of the
PHP_SDK_VC environment variable to PHP_SDK_VS).  You may have to adapt
custom tooling accordingly, though.

Thanks,
Christoph
