The third release candidates for the 1.85.0 release are now available at: <https://boostorg.jfrog.io/artifactory/main/release/1.85.0/source/> The SHA256 checksums are as follows: e712fe7eb1b9ec37ac25102525412fb4d74e638996443944025791f48f29408a boost_1_85_0_rc3.zip 7009fe1faa1697476bdc7027703a2badb84e849b7b0baad5086b087b971f8617 boost_1_85_0_rc3.tar.bz2 16d16b9658753117c1434e5450c5eac194957f4b6d0b390b9d07900d37c115a4 boost_1_85_0_rc3.7z be0d91732d5b0cc6fbb275c7939974457e79b54d6f07ce2e3dfdd68bef883b0b boost_1_85_0_rc3.tar.gz The changes from RC1 are: * Boost.ASIO docs generate very long file names that are not usable on Windows. * Boost.Program options does not build in C++23 mode on clang truck (to be clang 19 before boost 1.86.0 is released) Note: It is possible that this is a bug in clang, and it’s in a clang that is not released yet. * Boost.Log has some broken links in its documentation. * A meaningless change to Boost.Array (add a space to a test file) Apparently the RC2 tarballs were mis-buiilt; some of them were missing the required changes. I believe that RC3 resolves that problem. As always, the release managers would appreciate it if you download the candidate of your choice and give building it a try. Please report both success and failure, and anything else that is noteworthy. -- The Release managers
