gsl-lite v1.0.1

Fixes

• Add span<> constructor overloads for span<>::iterator arguments. (fec81ab6c4f10b99e3034c8926422fb39c5272ad)
  This improves backward compatibility, since our iterator used to be a pointer in v0.*, which made span{ otherSpan.begin(), 0 } work because we have constructor overloads that accept pointers.
• Add missing alias templates for polyfills. (62afbe9...

gsl-lite v1.0.0

Breaking changes

namespace gsl_lite and <gsl-lite/gsl-lite.hpp>

gsl-lite now lives in the single header file <gsl-lite/gsl-lite.hpp>, and all its symbols reside in namespace gsl_lite. By default, gsl-lite no longer defines a namespace gsl or the unprefixed Expects() and Ensures() macros for precondition and postcondition checking.

Additions:

• not_null<> now supports function pointers and nullable function objects such as std::function<> and (for C++11 and newer) defines a conditionally enabled forwarding operator() to permit function-call syntax (#353, thanks to @n0F4x)
