Jul 2017-SP1 bugfix release Build Environment * The Debian and Ubuntu installers have been fixed: there was a file missing in the Jul2017 release. * Added a new RPM called MonetDB-selinux which provides the SELinux policy required to run MonetDB under systemd, especially on Fedora 26. * The Windows installers (*.msi files) are now created using the WiX Toolset. * The Windows binaries are now built using Visual Studio 2015. Because of this, you may need to install the Visual C++ Redistributable for Visual Studio 2015 before being able to run MonetDB. Merovingian * monetdbd was leaking open file descriptors to the mserver5 process it started. This has been fixed.
