1.73.0:
Known Issues
------------
These are patches from library authors which were found too late to be fixed in the release. Be careful as they have not been through the normal testing process.
New Libraries
-------------
Nowide:
Standard library functions with UTF-8 API on Windows, from Artyom Beilis.
StaticString:
A dynamically resizable string of characters with compile-time fixed capacity and contiguous embedded storage, from Vinnie Falco and Krystian Stasiowski
Updated Libraries
-----------------
Align:
* Update aligned_alloc to support older mingw32.
Any:
* Speedup compilation by not including <algorithm>.
* Maintenance work, including CI hardening.
Asio:
* Fixed compatibility with C++20 concept syntax.
* Marked the POSIX descriptor classes' move constructors as noexcept.
* Added the ssl::host_name_verification class, which is a drop-in replacement for ssl::rfc2818_verification. The ssl::rfc2818_verification class has been marked as deprecated. As a consequence of this change, SSL support now depends on functions that were introduced in OpenSSL 1.0.2.
* Added an ssl::context constructor to take ownership of a native handle.
* Changed C++ language version detection with gcc to use __cplusplus macro.
* Fixed a work counting issue in the asynchronous resolve operation for endpoints.
* Fixed the strand<> converting constructors and assignment operators.
* Ensured that resolvers are restarted correctly after a fork.
* Fixed compatibility with the current NetBSD release.
* Removed spurious handler requirement checks in some async_read overloads.
* Changed the ssl::context class to propagate non-EOF errors from the add_certificate_authority function.
* Fixed a Windows-specific thread_pool destructor hang that occurred when the pool had an associated I/O object.
* Changed the select reactor to recreate the "self pipe trick" sockets on error. This addresses an issue on some versions of Windows, where these sockets are discconected after a system sleep.
* Fixed a compile error in the buffered streams due to the lack of reference collapsing in C++98.
* Changed the priority_scheduler example to demonstrate calls to shutdown() and destroy().
* Removed some unnecessary null pointer checks.
* Changed Windows platform detection to recognise TV titles as Windows apps.
* Added some emscripten compatibility patches.
* Fixed a compile error in the use_awaitable_t::as_default_on function.
* Changed all uses of the boost.bind placeholders to use the boost::placeholders namespace.
* Fixed a potential compile error in the async_compose implementation due to incorrect overload selection.
* Suppressed some non-virtual destructor warnings.
* Various documentation fixes and improvements.
Assert:
* Added source_location.
Atomic:
* Implemented C++20 atomic_ref. See docs and especially the caveats section.
* Implemented atomic_flag::test operation, which was introduced in C++20.
* atomic<T> should now take into account alignment requirements of T, which makes a difference if those requirements are higher than that of the internal storage of atomic.
* Added static asserts enforcing the requirements on the value type T used with atomic and atomic_ref. This should prohibit invalid types from being used as atomics.
* Improved internal lock pool implementation. The pool is larger, and lock selection accounts for atomic object alignment, which should reduce the potential of thread contention.
* Fixed incorrect x86 code generated for bit_test_and_* operations on 8 and 16-bit arguments. Other architectures are not affected.
* Fixed a possible unaligned memory access in compare_exchange_* operations, if alignment requirements of value_type are less than that of the internal storage of atomic.
* boost/atomic/atomic.hpp no longer includes boost/atomic/atomic_flag.hpp and boost/atomic/fences.hpp and only defines the boost::atomic class template and related typedefs. Include the other headers explicitly or use boost/atomic.hpp to include all parts of Boost.Atomic.
* The atomic<T>::storage() accessor and associated atomic<T>::storage_type type are deprecated. Instead, users are advised to use atomic<T>::value() and atomic<T>::value_type, respectively. Users can define BOOST_ATOMIC_SILENCE_STORAGE_DEPRECATION to disable deprecation warnings for the time of transition. The deprecated pieces will be removed in a future release.
* Removed support for BOOST_ATOMIC_DETAIL_HIGHLIGHT_OP_AND_TEST. This macro was used as a helper for transition to the updated returned values of *_and_test operations in Boost.Atomic 1.67, which was released 2 years before 1.73.
Beast:
* This is a maintenance update.
* Nested mutable_data_type in Beast dynamic buffers is deprecated.
* We'd love to know how you or your company use Beast, consider adding an entry to the Companies and Individuals Using Beast list.
* See the full Release Notes for a complete list of changes.
Context:
* IBM Z: Fix fcontext routines
* mips64/n64: .align 3
* Use OSPLAT MIPS32/MIPS64 to set different ABI
* Fix non-PIC in RISC-V assembly
Conversion:
* Added boost::polymorphic_downcast for references (thanks to Julien Delacroix for the patch).
* Significant docs update.
date_time:
* Support constexpr in c++14 and above
* Make date_time all inline. Users no longer need to link the library for any functions. Library remains for build compatibility.
* Deprecate support for legacy io and USE_DATE_TIME_PRE_1_33_FACET_IO macro
* Misc documentation updates and bugfixes.
DLL:
* Fixes and tests for demangling in boost::dll::smart_library
* Make UB sanitizers happy with boost::dll::load_mode::type
* Ceased dependence on MPL improving compile times
* Clang and ICC on Windows fixes and CI support for those platforms
* Maintenance work, including CI hardening and tests improving.
Dynamic Bitset:
* Fixed a portability issue in the definition of the maximum block limit.
Flyweight:
* Maintenance work.
Geometry:
* Improvements
- Missing input combinations in intersection() and introduction of tupled-output.
- Added d3::point_xyz geometry model (thanks to Digvijay Janartha).
* Solved issues
- Incorrect definition of EPSG:3785.
* Bugfixes
- R-tree exception-safety improvement.
- Andoyer inverse formula fixed for close points.
- Fixed dangling reference in distance algorithm.
* Deprecation
- Support for C++03 has been deprecated and Geometry will require C++14 from Boost 1.75 onwards.
GIL:
* Added move constructor and move assignment operator to image class
* New member function size() in any_image_view class
* Replace Boost.Test with Boost.LightweightTest as the only test framework used in GIL. This also restructured the test/extension/io/ sub-tree and targets in related Jamfile-s.
* Removed remaining uses of Boost.MPL
* Renamed all macros using BOOST_GIL_ prefix
* Renamed all CMake configuration options using BOOST_GIL_ prefix
* Removed extension/dynamic_image/reduce.hpp as unused and possibly unfinished. An implementation attempt of techniques described in the paper Efficient Run-Time Dispatching in Generic Programming with Minimal Code Bloat by Lubomir Bourdev, Jaakko Jarvi.
* Removed direct dependency on Boost.MPL, Boost.System and Boost.Test.
* Started removing public macros for compile-time configuration of I/O extension tests, i.e. BOOST_GIL_IO_TEST_ALLOW_READING_IMAGES and BOOST_GIL_IO_TEST_ALLOW_WRITING_IMAGES. Instead, if a test target is built, it builds all its test cases unconditionally.
* Avoid longjmp interaction during destruction of I/O extension objects.
* Fixed missing alignment default value in constructor of image class.
* Fixed segmentation fault when reading corrupted PNG file.
* Fixed illegal initialization of return values in the old IOv1 interface of I/O extension.
Histogram:
* Added crop command to reduce algorithm
* slice command in reduce now works on category axis
* Added count accumulator, can be used to add arbitrary metadata to each cell
* sum algorithm gained a new argument to optionally sum only over inner bins
* Several fixes for bugs in corner cases
* Enhanced documentation
icl:
* Remove references to date_time compiled library.
* Fix forward decl lower and upper less equal.
* Misc bugfixes.
IO:
* Made all the IOS state saver classes non-copyable. (Glen Fernandes)
* Correctly handle error upon first read from the input stream when reading a quoted string. (Glen Fernandes)
* Implemented ostream_joiner for delimiter based joining. (Glen Fernandes)
* Relocated ostream_string from the Utility library to the IO library as ostream_put.
* Correctly handle stream width and fill in quoted output. (Glen Fernandes)
* Optimize quoted output to write directly to the stream buffer. (Glen Fernandes)
* Glen Fernandes became the maintainer of the IO library.
LexicalCast:
* Maintenance work, including CI hardening and better workarounds for broken standard libraries
Log:
* Default sink used in trivial logging, when no sinks are registered in the logging core, now automatically flushes output after each log record
* core::flush now performs a flush on the default sink used for trivial logging, when no sinks are registered.
* Added a workaround for some syslog API implementations (e.g. glibc), which do not save the application identification string in openlog call. Such implementations could access already freed memory on each syslog call, resulting in undefined behavior.
* Fixed that log file rotation on a specific day of month (e.g. rotation_at_time_point(boost::gregorian::greg_day(1))) could be silently ignored and not happen.
* Fixed that text_file_backend::rotate_file could throw if there were no log records written yet and target file name pattern was set.
* Ported various components of the library to std::allocator_traits to improve compatibility with C++20 allocators.
* Fixed compilation errors when building in MSYS2 Cygwin environment.
Math:
IMPORTANT: C++03 support is now deprecated and will be removed from March 2021.
* Added Cubic Hermite Interpolation.
* Added Modified Akima Interpolation.
* Added PCHIP Interpolation.
* Added Quintic Hermite Interpolation.
* Added entropy to numerous distributions.
* Allow trivial quadrature case where the two end points are equal, and in addition allow bounds to be interchanged.
* Fix exp_sinh quadrature to work with complex types over a non-native range.
* Fix miscellaneous compiler warnings in factorial.hpp.
* Use std::chrono rather than boost::chrono in timed pFq calculations.
* Remove much of the old boost::mpl dependencies to improve constexpr support.
Mp11:
* Added mp_unique_if (contributed by Kris Jusiak)
* Added mp_flatten
* Added mp_rotate_left, mp_rotate_right (contributed by Duncan Barber)
* Added mp_compose
* Added mp_power_set
* Added mp_partial_sum
* Added mp_iterate
Multi-index Containers:
* multi_index_container is now AllocatorAware.
* Swapping of internal KeyFromValue, Compare, Hash and Pred objects now selects the appropriate swap function between std::swap and ADL candidates, in accordance with standard specifications in [swappable.requirements]
* Provided some internal copy constructors and assignment operators whose default implicit definition is deprecated in C++11 onwards ([depr.impldec]), which was warned about on some compilers.
Multiprecision:
* IMPORTANT: Mark C++03 support as deprecated and due for removal in 2021.
* Big update to cpp_int adds faster Karatsuba and Coomba multiplication routines.
* Fix conversion of gmp_rational to long double and __float128
* Fix up libtommath support to function with the latest libtom releases.
* Fix up some incompatibilities with the latest Intel C++ compiler.
* Fix up constexpr arithmetic support for latest MSVC release.
Outcome:
* Performance of Outcome-based code compiled by clang has been greatly improved. The previous implementation of Outcome's status bitfield confused clang's optimiser, which caused low quality codegen. Unlike most codegen issues, this was noticeably in empirical benchmarks of real world code, as was shown by P1886 Error speed benchmarking.
* The safe part of the better_optimisation Outcome v2.2.0 future branch was merged to Outcome v2.1.3 which includes a new status bitfield implementation. This appears to not confuse clang's optimiser, and clang 9 produces code which routinely beats GCC 9's code for various canned use cases.
* Installability is now CI tested per commit. Due to installability of standalone Outcome (e.g. make install) breaking itself rather more frequently than is ideal, installability is now tested on CI per commit.
* Newer Concepts implementing compilers were unhappy with the early check for destructibility of T and E, so removed template constraints, falling back to static assert which runs later in the type instantiation sequence.
* A false positive undefined behaviour sanitiser failure in some use cases of Experimental Outcome was worked around to avoid the failure message.
PolyCollection:
* Suppressed a potential redundant move warning in boost::poly_collection::for_each.
* Fixed a bug by which elements were copied rather than moved in allocator-extended move construction and move assigment between collections with non-propagating, unequal allocators.
* Allocator-extended move construction no longer decays to allocator-extended copy construction for the legacy version of libstdc++-v3 shipped with GCC 4.8 (which can also be used by Clang).
Stacktrace:
* Added documentation on distribution of PDBs
* Fixed msvc-9 build
* Maintenance work, including test fixes fixing typos CI improvements and hardening, inspect tool fixes.
Test:
* Boost.test v3.13 see the Changes log for more details.
* New feature: It is now possible to combine tolerance indication, user message and collection comparison modifier in a single BOOST_TEST expression. See change logs for more details.
ThrowException:
* Added an overload of throw_exception that takes a boost::source_location object.
* NOTE: Projects using BOOST_THROW_EXCEPTION with exceptions disabled will need to add a definition of this new overload.
TTI:
* Added introspection of function templates for more recent C++ compilers versions from gcc and vc++. as well as all versions of clang. Older versions of vc++ before 14.0 and gcc prior to 4.8 may fail.
* Added specific introspection for elements of struct/class, enum, and union types, which can be used for more fine-grained introspection than the general 'type' introspection.
TypeIndex:
* Maintenance work, including CI integration with inspect tool.
Utility:
* The ostream_string facility has moved from the Utility library to the IO library as ostream_put.
Variant:
* Removed unused includes
* Fixed zero-as-null-pointer-constat warnings
* Maintenance work, including typo fixes.
Variant2:
* Added support for std::hash, boost::hash.
* variant<T...> is now trivial when all types in T... are trivial. This improves performance by enabling it to be passed to, and returned from, functions in registers.
WinAPI:
* Headers in boost/detail/winapi are deprecated and will be removed in a future release.
* Boost.WinAPI headers no longer include winerror.h. Include boost/winapi/error_codes.hpp to get Windows error codes.
pkgsrc changes:
- for ruby-gilb2 and ruby-gobject-introspection gems,
handle generated source files that are no longer included
in distributed gem files by newly introduced GEM_KEEPBUILD
variable

LXQt is a free desktop environment with comparatively low resource
requirements. This makes it especially suitable for resource-constrained
personal computers such as netbooks or system-on-a-chip machines.
(Packaged in wip by pin@, additional changes by myself.)
This release contains plenty of new features, bug-fixes, and general
improvements. Some of the most important highlights include:
* We did it again, the MATE desktop environment is easier to use than before,
once the user starts the session. Do you want to hide applications startup?
Now you can set which applications to show on startup.
* Engrampa now has support for a handful of extra formats, as well as fixed
support for passwords and unicode characters in some of them.
* Eye of MATE now has support for Wayland and we’ve added support for
embedded color profiles.
* The thumbnail generation has been reworked and fixed in several places.
* Added support for webp files.
* Our window manager, marco, has gotten quite a few changes:
* We’ve brought a bunch of window decorations from the past to feed
your nostalgia.
* Finally added invisible resize borders. No more struggling to find a
border to grab with your mouse!
* All window controls (you know, the min, max, close buttons) are now
rendered in HiDPI.
* The Alt+Tab and Workspace Switcher popups have been entirely reworked.
Now they render in beautiful OSD style, are more configurable, and can
respond to keyboard arrows.
* Tiling windows with the keyboard now allows you to cycle through
different window sizes. You no longer need to feel constrained by only
half of your screen.
* The System Monitor panel applet now has support for NVMe drives.
* Calculator now supports using either “pi” or “π”.
* Scientific notation has been improved.
* Some fixes for supporting pre-defined physical constants.
* The Control Center now displays its icons correctly on HiDPI displays.
* A brand new Time And Date Manager app has been added.
* The Mouse app now supports acceleration profiles.
* The Preferred Applications app has been improved for accessibility, as well
as better support for integration with IM clients.
* The Indicator Applet has slightly better interaction with
oddly-sized icons.
* Speaking of icons, the network manager applet icons in our own themes have
been entirely redesigned and can now be enjoyed on HiDPI displays.
* If you’re the type of person that does not like to be disturbed when busy,
or giving a presentation, or watching a movie, you’ll be happy to know that
the notification daemon now supports a Do-Not-Disturb mode.
* The MATE Panel had several bugs that caused crashes in the past when
changing layouts. Those are now fixed!
* Support for Wayland compatibility has improved considerably.
* Status icons (a.k.a. notification area, or system tray) have support
for HiDPI displays.
* Wanda the Fish got a make-over and now you can enjoy her in full
HiDPI glory.
* The window list applet now supports window thumbnails on hover.
* Various accessibility improvements throughout the panel and its
core applets.
* If your system doesn’t, uh, support systemd you might be interested in
knowing that we’ve added support for elogind to both the MATE Screensaver
and the MATE Session.
* We’ve also added a brand new MATE Disk Image Mounter utility.
* Mozo, the menu editor, now supports Undo and Redo actions.
* Pluma plugins have now fully switched to Python 3.
* Pluma no longer has to envy anything from other complex editors, since it
can now show the formatting marks.
* i18n: All applications have been migrated from intltools to gettext.
Use logical replacements where possible - e.g, mpv is the more-common-now
fork of mplayer, quassel is now a more popular Qt IRC client than
Konversation and has more overlap with other packages on this list, etc.

Version 1.72.0
Asio:
Changed the async_initiate helper function to automatically deduce its return type, for C++11 or later.
Changed all asynchronous operations to use automatically deduced return types, for C++14 or later.
Introduced concepts to support async_initiate.
Added the nested template type rebind_executor to all I/O object types.
Changed the initiation function objects to report their associated I/O executor via the nested type executor_type and member function get_executor().
Added the default_completion_token trait, giving I/O executor types an associated default completion token type for use with asynchronous operations. This trait is specialised for the use_awaitable completion token, for example, to allow asynchronous operations to be used as follows: co_await socket.async_connect(my_endpoint).
Added missing async_initiate to the Windows-specific I/O objects' asynchronous operations.
Ensured that the executor type is propagated to newly accepted sockets.
Changed to require that Protocol copy and move operations never throw.
Changed to require that Endpoint default constructor and move operations never throw.
Added the noexcept qualifier to protocol accessors.
Added the noexcept qualifier to socket move constructors.
Fixed issues associated with opening serial ports on Windows:
Use the correct constant to initialise the RTS control flag.
Specify a default baud rate (9600).
Fixed a lost "outstanding work count" that can occur when an asynchronous accept operation is automatically restarted.
Consult the Revision History for further details.
Atomic:
Added a workaround for __float128 not being considered as a floating point type by some versions of libstdc++.
Improved compatibility with clang-win compiler.
Beast:
This is a maintenance update containing bug fixes, and updates to use the new features delivered in Boost.Asio.
We'd love to know how you or your company use Beast, consider adding an entry to the Companies and Individuals Using Beast list.
See the full Release Notes for a complete list of changes.
Circular Buffer:
Fix: max_size() now takes the allocator's max_size() into account. (Glen Fernandes)
Context:
architecture s390x supported
execution_context removed
Endian:
Made endian_reverse, conditional_reverse and *_to_* constexpr on GCC and Clang
Added convenience load and store functions
Added floating point convenience typedefs
Added a non-const overload of data(); changed its return type to unsigned char*
Added __int128 support to endian_reverse when available
Added a convenience header boost/endian.hpp
Filesystem:
Extracted filesystem_error to exception.hpp; file_status and associated enums and functions to file_status.hpp; directory_entry, directory_iterator and recursive_directory_iterator to directory.hpp.
Deprecated: For backward compatibility operations.hpp still includes the new headers exception.hpp, file_status.hpp and directory.hpp, unless BOOST_FILESYSTEM_NO_DEPRECATED macro is defined. These implicit includes are considered deprecated and will be removed in a future release. Users are encouraged to include the new headers directly or include filesystem.hpp.
The filesystem_error exception is now implemented in the compiled library of Boost.Filesystem. Users may need to add linking with Boost.Filesystem library in their projects.
On POSIX.1-2008 platforms, use utimensat instead of utime. utime is declared obsolete in POSIX.1-2008 and can be disabled e.g. in uClibc-ng.
directory_iterator is now left in the end state on memory allocation errors.
In directory_iterator on POSIX systems, support for readdir/readdir_r has been reworked to avoid memory allocations for dirent structures when readdir is used. This reduces memory consumption and eliminates the possibility of buffer overruns in case if readdir produces a very long directory name.
On Windows, use Boost.WinAPI to select the target Windows version.
New: Added directory_options enum, which reflects the same named enum from C++20. The enum is supported in directory_iterator and recursive_directory_iterator to customize iteration behavior. In particular, the iterators now support skipping directories that can't be opened due to insufficient permissions. The symlink_option enum is now deprecated and should be replaced with directory_options.
By default, recursive_directory_iterator is now reset to the end state in case of errors, as required by C++20.
New: Added directory_options::pop_on_error option, which configures recursive_directory_iterator so that it attempts to recover from iteration errors by repeatedly invoking pop() until it succeeds or the end state is reached.
New: Added directory_options::skip_dangling_symlinks option, which configures recursive_directory_iterator so that it doesn't follow dangling directory symlinks and continues iteration instead of reporting an error.
Deprecated: The following members of recursive_directory_iterator are now marked as deprecated: level(), no_push_pending(), no_push_request(), no_push(). Users are advised to replace their use with the standard counterparts: depth(), recursion_pending(), disable_recursion_pending(). Note that recursion_pending() has the opposite meaning compared to no_push_pending() and no_push_request(). Deprecated methods will be removed in a future release.
Fixed path::lexically_relative (and any dependent algorithms) to correctly handle empty, dot and dot-dot path elements in its argument. The behavior is made closer to C++17 std::path::lexically_relative in that empty and dot path elements are ignored and dot-dot path elements are accounted by decreasing the number of dot-dot path elements to generate in the resulting relative path.
Functional/Factory:
Glen Fernandes rewrote the implementations of factory and value_factory to provide the following features:
Support r-value arguments when possible
Support arbitrary number of arguments via variadic templates when possible
Support allocators that are final
Support allocators that use fancy pointers

Fix bug in variable precision mpf_float which causes it to go into a tailspin trying to select the correct precision - see https://github.com/boostorg/multiprecision/issues/164.
Outcome:
Enhancements:
Standalone outcome is now make install-able, and cmake find_package() can find it. Note that you must separately install and find_package() Outcome's dependency, quickcpplib, else find_package() of Outcome will fail.
The git submodule mechanism used by standalone Outcome of specifying dependent libraries has been replaced with a cmake superbuild of dependencies mechanism instead. Upon cmake configure, an internal copy of quickcpplib will be git cloned, built and installed into the build directory from where an internal find_package() uses it. This breaks the use of the unconfigured Outcome repo as an implementation of Outcome, one must now do one of: 1. Add Outcome as subdirectory to cmake build. 2. Use cmake superbuild (i.e. ExternalProject_Add()) to build and install Outcome into a local installation. 3. Use one of the single header editions.
For standalone Outcome, the current compiler is now checked for whether it will compile code containing C++ Concepts, and if it does, all cmake consumers of Outcome will enable C++ Concepts. Set the cmake variable CXX_CONCEPTS_FLAGS to an empty string to prevent auto detection and enabling of C++ Concepts support occurring.
OUTCOME_TRY operation now hints to the compiler that operation will be successful. [P1886 Error speed benchmarking](https://wg21.link/P1886) showed that there is considerable gain in very small functions by hinting to the compiler whether the expression is expected to be successful or not. OUTCOME_TRY previously did not hint to the compiler at all, but now it does. A new suite of macros OUTCOME_TRY_FAILURE_LIKELY hint to the compiler that failure is expected. If you wish to return to the previously unhinted behaviour, define OUTCOME_TRY_LIKELY(expr) to (!!expr).
Support for C++ Coroutines has been added. This comes in two parts, firstly there is now an OUTCOME_CO_TRY() operation suitable for performing the TRY operation from within a C++ Coroutine. Secondly, in the header outcome/coroutine_support.hpp there are implementations of eager<OutcomeType> and lazy<OutcomeType> which let you more naturally and efficiently use basic_result or basic_outcome from within C++ Coroutines -- specifically, if the result or outcome will construct from an exception pointer, exceptions thrown in the coroutine return an errored or excepted result with the thrown exception instead of throwing the exception through the coroutine machinery (which in current compilers, has a high likelihood of blowing up the program). Both eager<T> and lazy<T> can accept any T as well. Both have been tested and found working on VS2019 and clang 9.
make_error_code() and make_exception_ptr() are now additionally considered for compatible copy and move conversions for basic_result<>. This lets you construct a basic_result<T, E> into a basic_result<T, error_code>, where E is a custom type which has implemented the ADL discovered free function error_code make_error_code(E), but is otherwise unrelated to error_code. The same availability applies for exception_ptr with make_exception_ptr() being the ADL discovered free function. basic_outcome<> has less support for this than basic_result<> in order to keep constructor count down, but it will accept via this mechanism conversions from basic_result<> and failure_type<>.
