 -   @ref Platform::GlfwApplication::exec() now asserts instead of crashing if
     the constructor fails to create a window (see [mosra/magnum#192](https://github.com/mosra/magnum/issues/192),

+-   @ref Platform::GlfwApplication::GLConfiguration::isSrgbCapable() has now
+    a proper documented default value instead of being left uninitialized.
 -   @ref Math::sclerp() was not properly interpolating the translation if
     rotation was the same on both sides
