Changelog for the Windows Installer

0.5.0 (2019-07-11)

Debug symbols, which are not needed at runtime, are stripped from most
binaries, resulting in a noticeably smaller install footprint. Now the
installer and the installation itself are smaller despite packing in more
features!
Includes a copy of git in the SageMath Shell, so no need to install a
separate Git or integrate an existing Git for Windows installation.
Installing the HTML documentation is now optional. Although some help
features won't work without it, it saves about 600 MB of installation
size, and if you have an internet connection you can still read the docs
at doc.sagemath.org.
Updates to use a few more Cygwin system packages rather than including
Sage-specific copies, including:
- bzip2
- libffi
- libpng
- patch
- pcre
- xz
- yasm
- zlib
We still build our own copies of MPIR and anything that depends on it,
as there are still too many bugs with the system GMP on Cygwin.
