Container:
-
Fixed bugs/issues:
-
-
Core:
-
CRC:
-
C++03 is no longer supported; a C++11 compiler is required. (This includes GCC 4.6 or later, and MSVC 10.0 (VS 2010) or later.)
-
Removed dependencies on Array, Config, Integer, and TypeTraits. The library is now standalone.
-
-
Filesystem:
-
is_empty
operation is now better protected against concurrent filesystem modifications. -
On POSIX systems,
is_empty
now indicates error if invoked on a file other than a regular file or a directory. -
On Windows, fixed
file_size
andis_empty
operating on symlinks rather than the files the symlinks refer to. (#313) -
directory_entry::refresh
no longer throws an exception if the file referenced by the entry doesn't exist. This makesdirectory_entry::status
anddirectory_entry::symlink_status
, as well as methods based on them, behave similarly to the equivalent standalone operations. The fact that the file does not exist is still indicated via theerror_code
returned by the correspondingdirectory_entry::refresh
overload, or can be seen by testing if the file type returned bydirectory_entry::status
ordirectory_entry::symlink_status
calls isfile_type::file_not_found
. (#314) -
Fixed
weakly_canonical
testing path elements for existence relative to the current path instead of the base path specified in the call, if the input path was a relative path. -
On Windows, fixed
weakly_canonical
producing incorrect result path when the input path started with "..". (#311)
-
-
Format:
-
C++03 is no longer supported; a C++11 compiler is required. (This includes GCC 4.7 or later, and MSVC 12.0 (VS 2013) or later.)
-
-
Function:
-
Removed dependency on Boost.TypeTraits.
-
Brought back the
argN_type
typedefs that were accidentally lost in 1.85.
-
-
GIL:
-
Added

Graph:
-
Major update: C++14 is the new minimum standard; this was partly dictated by dependencies (at least to C++11) and partly by choice. If you require support for an older standard, please contact the maintainer.
-
Remove direct dependency on Boost.Regex.
-
Fix several compilation errors caused by not explicitly including common headers.
-
isomorphism
: Fix docs, ignorevertex_max_invariant
parameter in favour of cheaply calculating upper exclusive bound, fix bug with Associative Property Map, improve space efficiency from linear in the size of the maximum invariant to linear in the size of g1. -
boykov_kolmogorov_max_flow
: Fix named parameter overload. -
adj_list_edge_iterator
: Fix maybe-uninitialized warnings. -
hawick_circuits
: Add a parameter to optionally limit the depth of the search, causing a potentially suboptimal answer to be returned early. -
disjoint_sets
: Improve performance oflink_sets
by removing redundant lookup of set representatives. -
maximum_adjacency_search
: Refactor and more tests. -
property
: UseBOOST_ATTRIBUTE_NO_UNIQUE_ADDRESS
to remove wasted space. -
labeled_graph
: Fixremove_labeled_vertex
so that it actually removes the label too. -
r_c_shortest_paths
: Fix bug that the single-solution variant did not always return the shortest path. -
read_graphviz
: Fix stack overflow (oss-fuzz issue 66719) and non-keyword subgraph parsing. -
Many miscellaneous improvements: broken links, typos, etc.
-
-
JSON:
-
Support for GCC versions older than version 5.0 is deprecated and will stop in Boost 1.88.0.
-
source_location
parameter was added to throwing accessor functions. -
Parse option to tolerate invalid UTF-16 surrogate pairs, and produce WTF-8.
-
Added accessor functions that return
system::result
. -
Handle missing error case in direct parsing.
-
-
LexicalCast:
-
Fixed conversion of
std::basic_string_view
andboost::basic_string_view
containing one or more\0
characters. Issue was introduced in 1.85.0.
-
-
leaf:
-
More optimal verbose_diagnostic_info implementation.
-
Bug fixes.
-
Added [[nodiscard]] to class result<>.
-
-
Locale:
-
Add support for custom allocators in
conv::utf_to_utf
-
Don't build examples by default
-
-
Math:
-
Correct Bessel function results at infinity, see 1143.
-
Improve Non Central T numerical stability, see scipy20693.
-
Correct
float_next
/float_prior
behaviour at infinity. -
Prevent spurious underflow in non-central beta, see scipy20693.
-
Add improvement to Heuman Lambda precision.
-
Improve Skew Normal root finding, see 1120.
-
Lots of minor fixes and improved code coverage.
-
-
MySQL:
-
The long-deprecated functions
query
,start_query
,execute_statement
andstart_statement_execution
(and their async equivalents) have been removed. -
Breaking changes to experimental APIs:
-
The
identifier
class (client-side SQL formatting) has been removed. Use the new format specifiers feature, instead. -
The required interface for custom formatters has been changed to accomodate the new format specifiers API.
-
any_connection::async_connect
now requires that itsconnect_params
argument be kept alive until the operation completes. The overload taking aconst connect_params*
has been removed. -
character_set::name
is now aconst char*
instead of astring_view
, as MySQL character set names can't contain NULL characters. -
any_connection
internal buffer is now limited to 64MB. If you need to read or write rows bigger than that, increaseany_connection_params::max_buffer_size
.connection
and their helper typedefs are not limited. -
Renamed
any_connection_params::initial_read_buffer_size
toinitial_buffer_size
. -
Renamed
pool_params::initial_read_buffer_size
toinitial_buffer_size
.
-
-
New experimental API: pipelines. Pipelines can increase efficiency by coalescing several requests in a single network packet. Pipelines can be used to run text queries, prepare, execute and close statements, reset session state and set the connection's character set.
-
Client-side SQL formatting now supports ranges out of the box. Formatting can be further customized using the new
sequence
function. Use cases like batch inserts and batch lookups can be significantly simplified using this functionality. -
Client-side SQL formatting now supports format specifiers which modify how values are formatted.
{:i}
formats a string as a dynamic SQL identifiers, and{:r}
outputs a raw unescaped -
The static interface (
static_results
andstatic_execution_state
) now supports Boost.Pfr types usingpfr_by_name
andpfr_by_position
. Addedunderlying_row_t
to support such types. -
date
anddatetime
can now be constructed from and converted to C++20std::chrono::local_time
. -
Added
any_connection_params::max_buffer_size
, which allows to set a limit to the connection's internal buffer. -
Added
is_fatal_error
, which allows users can now distinguish between fatal (which require closing and re-opening the connection) and non-fatal error codes. -
Added
formattable_ref
, a type-erased reference type that can refer to any type satisfying theFormattable
concept. -
Fixed an ODR violation under MSVC which could cause crashes in release builds when using Boost.MySQL with other code also using
asio::coroutine
in different translation units.
-
-
Process:
-
Moved the old boost.process to v1 subfolder and inline namespace. deprecated process/*.hpp v1 headers
-
Turned v2 into a compile library.
-
Fixed usage on alpine linux / musl
-
-
Stacktrace:
-
Big new feature: stacktrace from arbitrary exception for Windows.
std::stacktrace::from_current_exception()
now works on Windows platform. Many thanks to huangqinjin for the implementation PR#159 Now on POSIX and Windows thefrom_current_exception()
function returns the stacktrace of the current exception object as if the stacktrace was captured at the point of throwing the exception. -
Fixed inclusion of rarely used Windows SDK headers which can cause conflict with other code using Windows SDK. Thanks to Marat Abrarov for fixing the issue PR#157.
-
Build option
boost.stacktrace.from_exception
now properly works on MacOS. Thanks to Peter Dimov for the fix PR#166. -
Fixed a typo in assert expression. Thanks to Kilian Henneberger for the bug report #164.
-
Fixed shadowing warnings. Thanks to Nigel Stewart for the bug report #141.
-
Added
dladdr
minimal support for AIX. Many thanks to Clément Chigot for the implementation PR#114. -
Significant improvement of CMake: multiple fixes, added many new tests, improved CI. Many thanks to Peter Dimov for all the improvements.
-
Fix addr2line work when the process is looked up via
PATH
. Thanks to Schreischildkroete for the bug report and to Jens Richter for fix #72.
-
-
Test:
-
Fix
-Wundef
in configuration step. -
Fix unreachable return compilation error on MSVC.
-
-
Unordered:
-
Added container
pmr
aliases when header<memory_resource>
is available. The aliasboost::unordered::pmr::[container]
refers toboost::unordered::[container]
with astd::pmr::polymorphic_allocator
allocator type. -
Equipped open-addressing and concurrent containers to internally calculate and provide statistical metrics affected by the quality of the hash function. This functionality is enabled by the global macro
BOOST_UNORDERED_ENABLE_STATS
. -
Avalanching hash functions must now be marked via an
is_avalanching
typedef with an embeddedvalue
constant set totrue
(typically, definingis_avalanching
asstd::true_type
).using is_avalanching = void
is deprecated but allowed for backwards compatibility. -
Added Visual Studio Natvis framework custom visualizations for containers and iterators. This works for all containers with an allocator using raw pointers. In this release, containers and iterators are not supported if their allocator uses fancy pointers. This may be addressed in later releases.
-
-
UUID:
-
Major update.
-
C++03 is no longer supported, a C++11 compiler is required. (This includes GCC 4.8 or later, MSVC 14.0 (VS 2015) or later, and MinGW-w64.)
-
Decreased number of Boost dependencies from 39 (in total) to just 5.
-
Updated to reflect the newer RFC 9562.
-
Added generators for time-based UUIDs.
-
Many other improvements, see the revision history.
-
-
WinAPI:
-
Added
BOOST_USE_WINAPI_VERSION
CMake option, which allows users to specify the Windows version for Boost to target.
-
Updated Tools
-
BoostBook:
-
DTD updated:
constructor
,copy-assignment
anddestructor
elements are now allowed insidemethod-group
elements. -
Many fixes and improvements in Doxygen-generated documentation:
-
Fixed duplicate equal signs in Doxygen-generated enum value initializers.
-
Disabled alphabetical sorting of function arguments. The sorting can be re-enabled by setting the new
boost.sort.params
XSL parameter to 1. -
Added support for custom class member grouping. See Doxygen tags
@name
and@{
/@}
. -
Added support for Doxygen references to classes, methods, enums, variables, etc. (see
@ref
tag). -
Added support for
@remark
and@important
tags. -
Added support for
@parblock
tags, which can be used to place multiple paragraphs under a tag that expects a single paragraph as an argument (e.g.@returns
). -
Template parameter defaults that refer to implementation details are now concealed, similar to function parameter defaults.
-
Improved presentation of unnamed enums. Instead of showing a synthesized name such as
@0
, the name is either omitted or is[unnamed]
, if the name is necessary to introduce a link to the enum documentation. -
Changed the "See Also" (
@sa
) blocks to be displayed inline, similar to "Returns". -
Fixed presentation of multiple exception specifications (
@throws
). -
Added support for free form description of throwing behavior. If the exception type after the
@throws
tag is "~" then the exception type is omitted from the output, and the following description is displayed directly in the "Throws" section. -
Removed redundant spaces in return types and template parameters.
