 [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])
+

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

Gennaro Prota	8a352e253a	Use the do {} while (false) idiom for BOOST_TEST_THROWS() and BOOST_TEST_NO_THROW() Reason: Common hygiene for multi-line macros. 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
