 [section Revision History]

+[section Changes in 1.90.0]
+
+* The implementation of `BOOST_TEST_THROWS` and `BOOST_TEST_NO_THROW` macros defined in
+  [link core.lightweight_test `boost/core/lightweight_test.hpp`] has been changed to avoid
+  compiler warnings on some compilers, when the macros are used in `if`/`else` blocks. As
+  a side effect of this change, the semicolon after the macro is now necessary. ([github_pr 205])
+* [link core.data `boost::data`] and [link core.size `boost::size`] are now aliases for `std::data`
+  and `std::size`, respectively, when the latter are provided by compiler. This resolves potential
+  ambiguities when both `boost::` and `std::` alternatives are found by the compiler, e.g. as a result
+  of ADL. ([github_issue 206])
+
+[endsect]
+
+[section Changes in 1.89.0]
+
+* Fixed `bit_ceil` to return 1 for input 0 as per specification. ([github_pr 199])
+* Added support for `std::format` to `boost::core::string_view`. ([github_issue 190])
+
+[endsect]

Andrey Semashev	3cd29323be	Add a test for boost::span verifying unqualified calls to data()/size().

Andrey Semashev	45bd9bf69b	Use std::data and std::size for boost equivalents, when possible.

Makes things like if (condition) BOOST_TEST_THROWS(...); else ... work correctly. Also, it doesn't generate an empty statement (which compilers may warn about) when the user adds a semicolon (which they usually do).	2025-10-09 19:00:47 +02:00

Dirk Stolle	c48b7f269f	Move Ubuntu 20.04 builds to container or newer Ubuntu version The Ubuntu 20.04 image on GitHub Actions will be unavailable by 2025-04-15. See <https://github.com/actions/runner-images/issues/11101> for more information on the deprecation and removal. Therefore all build jobs that use the Ubuntu 20.04 runner image of GHA have to be either migrated to a newer runner image (if the compiler version is available on a newer image) or have to be moved to Docker containers using Ubuntu 20.04 (if the compiler version is not available on the newer runner images).	2025-04-16 02:07:28 +02:00
