Thank you for patching your release to suit your customers.
Currently we release PixInsight on four major platforms: FreeBSD, Linux, macOS and Windows. The operating systems supported by current PixInsight versions (>= 1.8.7) are:
- FreeBSD 12
- Linux with glibc version 2.27 or later
- macOS 10.12 or later
- Windows 10
We cannot have the human and time resources necessary to support Windows 7 and Windows 8.1 actively. Both are dead operating systems without any future:
Windows 8.1: End of mainstream support happened on January 9, 2018
Windows 7: End of extended support will happen next January 14, 2020
Asking us to support those Windows versions actively would be the same as asking us to support any Linux distribution released in 2010, or macOS 10.6 Snow Leopard, or 32-bit operating systems, which were still mainstream in 2009. That just does not make any sense. We must look forward, not backward.
As for market shares, the PixInsight project has never worked that way. We don't care about the percentages of users on each platform. We just want to do our work the best way we can on the platforms where we can develop our software better and more efficiently. We need to be happy doing our day to day development and programming work, and for this reason our primary development platforms are without any doubt Linux and FreeBSD. The macOS and Windows versions of PixInsight are ports of the main development trunk on Linux.
