Ubuntu 17.10 comes with Firebird 3.0.2

Ubuntu 17.10 is released and it comes with Firebird 3.0.2 (Latest stable version)

Thanks to Damyan  Ivanov and Debian project contributors to Firebird packages

Visual Studio 2017 Version 15.4 Released

You can now use CMake for Linux C++ development in Visual Studio

That could be interesting in cross compiling Firebird from Windows side to Linux/WSL

Firebird 3 on Apple IOS

One side effect of new Firebird 3.0.3 builds for Apple Macosx is that now there is a Mach-O dynamically linked shared library for arm_v7 that can be used on IOS.
You can ask for details on Firebird-devel 
ps: For Firebird 2.5.x there is a build on Paul's blog also Egor Pugin created Cmake files for IOS Builds (I didn't tested that route yet)
