FIX Antenna C++/.NET 2.27.1 release: scheduler component is implemented

B2BITS, EPAM Systems company is pleased to announce the release of version 2.27.1  FIX Antenna C++ /.NET.

The major features of this release are Scheduler component and flexible affinity mask setup, see below. Scheduler component allows user to create and execute flexibly defined sessions schedules, see the documentation.

This is the last release that supports Centos 6 and Visual Studio compilers prior to Visual Studio 2015. So, please be informed that Centos 6 configurations along with Visual Studio prior 2015 will be discontinued starting next release. Windows configurations will be reduced to only one - Visual studio 2015 in particular since starting 2015 studio ABI compatibility is maintained across compilers versions, so library built with 2015 studio can be used with 2015/2017/2019. Linux configurations will be reduced to only three: Centos 7 gcc4.8, Centos 7 gcc5.2, Ubuntu gcc6.1
