Several minor features have been added to this release, and a few
minor fixes.

This contains the following changes:

• Updates underlying_type to SFINAE if type is not an enum (#18)
• Adds is_[nothrow_]invocable_r, which was missing from previous
  release
• Fixes some inline visibility bugs surrounding optional
• Adds conditionally explicit span constructors (#21)
  • This is potentially a breaking change -- however this is not bumping
    the major version of this library since the previous implementation
    was following the experimental API of span -- which was not the
    final version
• Fixes /W4 warnings for MSVC

This release contains a new feature functionality and a bugfix

Changes

• Fixes bpstd::get for tuple on gcc-4.9
• Implements multi-variant visitation (#16)

This release just includes a simple bug fix.

Changes

• Fixed any_cast to work with reference types (T&/const T&/T&&)

This is the first official release of the Backport-C++ library!

This implements the following C++ standard types / features with full, tested, compatibility for C++11:

Types

C++20

• std::span in <bpstd/span.hpp>

C++17

• std::optional in <bpstd/optional.hpp>
• std::any in <bpstd/any.hpp>
• std::string_view in <bpstd/string_view.hpp>
• std::variant in <bpstd/variant.hpp>
• std::byte in <bpstd/cstddef.hpp>
• std::bool_constant in <bpstd/type_traits.hpp>

C++14

• Transparent operation functors (e.g. std::greater<>) in [<bpstd/functional.hpp>`](https://github.com/bitwizeshift/BackportCpp/blob/v1.0.0/include/bpstd/functional.hpp)
• std::integer_sequence in <bpstd/utility.hpp>

Features

C++20

• std::to_address in <bpstd/memory.hpp>
• std::make_unique_for_overwrite in <bpstd/memory.hpp>
• std::is_nothrow_convertible in <bpstd/type_traits.hpp>

C++17

• Various newly added type-traits (std::void_t, std::is_invocable, std::is_[nothrow_]swappable[_with], etc) in <bpstd/type_traits.hpp>
• std::not_fn in <bpstd/functional.hpp>
• std::make_from_tuple in <bpstd/tuple.hpp>
• std::apply in <bpstd/tuple.hpp>
• std::invoke in <bpstd/functional.hpp>
• std::uncaught_exceptions in <bpstd/exception.hpp>

C++14

• _t type traits in <bpstd/type_traits>
• User defined literals for various types
• Various type-traits
• std::get for addressing tuples by type in <bpstd/tuple.hpp>
• std::exchange in <bpstd/memory>
• std::make_reverse_iterator in <bpstd/iterator>
• std::make_unique in <bpstd/memory>

In preparation of a 1.0.0 release, this includes a lot of changes from the previous few weeks of development:

Change Log

Fixes

• Fixed is_final definition, which is not available until C++14
• Suppressed and fixed cppcheck warnings

Features

• Added make_reverse_iterator support
• Added uncaught_exceptions
• Added support for addressing tuples by type
• Added user-defined literals for complex
• Added visibility attributes on all definitions
• Added initial implementation of variant

This pre-release introduces some bugfixes from the previous release

Changes

• Fixed MSVC 2019 build failures from bpstd::span::reverse_iterator (#7)
• Fixed broken bpstd::any_cast(const any&) (#6)
• Fixed erroneous documentation in <utility>

This is a pre-release of the library, which contains much of the C++14, C++17, and C++20 utilities/types compiling and working for all C++ compilers capable of compiling syntactically valid C++11 code.

Notably absent for utility types is std::variant, which is part of the 1.0.0 milestone.

This is release 0.0.1, geared towards gcc and clang compilers on Linux and Mac.

This is a nearly complete release, missing only bpstd::variant implementation.
This currently does not compile successfully on Windows for either cl or clang-cl

This includes the following types:

• bpstd::span
• bpstd::to_address
• bpstd::make_unique_for_overwrite
• bpstd::any
• bpstd::string_view
• bpstd::optional
• bpstd::invoke
• bpstd::not_fn
• bpstd::make_from_tuple
• bpstd::apply
• bpstd::byte
• bpstd::make_unique
• _t convenience traits
• _v convenience variables (when compiling with -std=c++14)
• deduced functional objects
