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
Support for disabled exceptions (BOOST_NO_EXCEPTIONS)
Improved compilation times
The following features have been removed:
Increasing limits for C++03 compilers through BOOST_FUNCTIONAL_VALUE_FACTORY_MAX_ARITY
Using boost::none_t in place of void through BOOST_FUNCTIONAL_FACTORY_SUPPORT_NONE_T

Added The Empirical CDF distribution.
Reworked the Sterling approximation used by multiprecision gamma functions to be applicable to all the function that use the Lanczos approximation at regular precision. Also extended Lanczos approximations up to 100 decimal digit precision.
Multiprecision:
Big constexpr update allows cpp_int and float128 arithmetic to be fully constexpr with gcc and clang 9 or later, or any compiler supporting std::is_constant_evaluated().
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<>.
Bug fixes:
The detection of [[nodiscard]] support in the compiler was very mildly broken.
PolyCollection:
Maintenance work.
Preprocessor:
Topic added which discusses emptiness
Support for the C++20 __VA_OPT__ construct
BOOST_PP_VARIADIC_HAS_OPT whether __VA_OPT__ is supported at the C++20 level
BOOST_PP_CHECK_EMPTY test for emptiness using __VA_OPT__ at the C++20 level
BOOST_PP_VA_OPT more flexible alternative to __VA_OPT__ at the C++20 level
Smart Pointers:
Implemented allocate_unique for scalars and arrays. (Glen Fernandes)
Test:
Boost.test v3.12 see the Changes log for more details.
New feature:
Support for C++17 std::string_view has been added.
Better diagnostic on boost::exception and no rtti mode (thanks to Mikhail Pilin / [pull_request 234])
VMD:
BOOST_VMD_IS_EMPTY updated to use __VA_OPT__ at the C++20 level has 100% reliability
Add php74-extensions packages as php73-extensions.
This package does not contain anything by itself -- it is a
"meta-package" that depends on other PHP packages. Its sole purpose is
to require dependencies so users can install this package only and
have all the PHP stuff pulled in by the package dependency mechanism.
