This is the first "major" release of cxxomfort for 202x and thus it is marked as release and trunk. Users pulling from the default repo should be able to upgrade automagically.

There are a number of major, "shaking" changes starting with this version which feature what could be considered the "final" structure for the project. Among the most important:

* The baseline is now more streamlined. In fact, it is possible from now on to set up a minimal base with only the cxxomfort basics by keeping only these five files and folders:
cxxomfort.hpp, base.hpp, config.hpp, base/, config/. * Starting this version cxxomfort no longer requires a TR1 forwarder (and in fact, might not even work with one) when working with compilers in pre-C++11 mode that require one (see Per-Compiler Notes in the wiki). * Conversely, when needing a TR1 implementation (such as in pre-TR1 compilers), the library now honors the previously unsupported macro CXXOMFORT_USE_INTERNAL_TR1 which enables automatically a minimum TR1 featureset. * The compiler now discerns between a C++98/03 mode with TR1 support available ("C++2007"), normal C++98 mode, and a C++ mode without C++98 support ("pre-1997"). This distinction is mostly relevant for compilers such as MSVC <= 2008 and OpenWatcom. * Some files from external sources are now moved to a vendor directory space. * When on Windows, the library now requires and enforces the value of the __STDC_LIMIT_MACROS macro.

This release has been tested on: GCC 4.6 to 5.5 in C++03 mode; GCC 4.6 to 6.0 in C++11 mode; GCC 6 in C++14 mode; MSVC 2008 SP1; MSVC 2012; MSVC 2013 (partially); clang 3.0 to 3.4 in C++03 mode; clang 3.2 to 4.0 in C++11 mode; clang 4.0 in C++14 mode; Open Watcom CI release (partial).

The autogenerated documentation ( http://ryan.gulix.cl/fossil.cgi/cxxomfort/uv/html/) is updated for this release.

Planned updates for the future:

• Evaluating in full invoke() for C++03.
• Backporting shift operations from <algorithm> down to at least C++11.
• Backporting bind_front() down to at least C++11.
• Backporting bit_cast() down to at least C++11.
• A true arithmetic type with sizeof()==1 (à-la signed/unsigned char).
• p0192 "short floats" (16-bit floating point types for storage only).
• p1402 "cstring_view" (view of native C++ strings).
• Refining is_contiguous_sequence.
• "Moving" accumulate and partial_sum as per p0616.

[1] "27F": The release coincides with the 10th anniversary of the 27F Event or Great Cobquecura Earthquake of 2010 (2010-02-27): see https://en.wikipedia.org/wiki/2010_Chile_earthquake . This is why I say it is a shaking release. check-in: 4dad71eb user: luismachuca tags: trunk, clang_min_302, msvc_min_1500, openwatcom_min_200, release, y2020, gcc_min_406

While compilers like MSVC 2005 and OpenWatcom do not have TR1 and thus are not supported, the current build organizes things so that more of the core features can be used before a hard fail. In particular, byte, declval, string_view, to_string and in the future in a limited manner reference_wrapper, errc and unique_ptr should be at least minimally usable. check-in: b1a27cd4 user: luismachuca tags: trunk

Starting with this version, we'll hopefully also see more isolated, atomic commits, in particular when it comes to features that have to go inside the fix:: namespace. check-in: 4dc2d6a4 user: luismachuca tags: trunk, y2019, pre-release, msvc_max_1700, gcc_max_505

This is a relatively large commit in terms of code changes limited to mostly type_traits related functionality. It also provides better material to construct doxygen documentation.

An important breaking change is that now cxxomfort::cxxostd::byte is no longer constructible from unsigned char; instead, it must always be constructed via to_byte, in line with both C++17 and a number of implementations. check-in: bfec01f8 user: luismachuca tags: trunk
