I'm currently running:
Version: (2017-05-12 revision b823d0b78)-makepkg, release build
Libraries: wxWidgets 3.0.2
libcurl/7.52.1 OpenSSL/1.0.2k zlib/1.2.11 libssh2/1.8.0 nghttp2/1.19.0 librtmp/2.3
Platform: Windows 7 (build 7601, Service Pack 1), 64-bit edition, 64 bit, Little endian, wxMSW
- Build Info -
wxWidgets: 3.0.2 (wchar_t,wx containers,compatible with 2.8)
KiCad - Compiler: GCC 6.3.0 with C++ ABI 1010
..and have to say it's stable and usable - knocks on wood. Did a single A3 sheet design over the last 5 days with it and I'm nearly done with the layout in Legacy Canvas (can't talk for OpenGL as I didn't use it).
No problems what so ever - computer was running non stop and so was KiCAD.
