From Nsnam
On February 9, 2024, ns-3.41 was published. This page lists some issues that have been fixed in the mainline since that time. If considered impactful enough, the maintainers may make an update to this release to cover some or all of these issues.
Build failure on macOS clang 15.0.0 (Xcode 15.3)
Recent Xcode updates (to version 15.3) started to trigger a test compilation failure:

The following patch to the source code can be applied as a workaround, or ns-3-dev may be used, or tests can be disabled:
Build failure on macOS version 14.3.1 or greater
A compilation error may be observed (sometimes in normal builds, sometimes only when clang-tidy is enabled) for macOS versions 14.3.1 or greater (Apple clang version 15.0.0 (clang-1500.1.0.2.5)).
