Significant Known Problems
==========================
libc++ Changes
==============
Users that wish to link together translation units built with different
versions of libc++'s headers into the same final linked image should define the
`_LIBCPP_HIDE_FROM_ABI_PER_TU` macro to `1` when building those translation
units. In a future release, not defining `_LIBCPP_HIDE_FROM_ABI_PER_TU` to `1`
and linking translation units built with different versions of libc++'s headers
together may lead to ODR violations and ABI issues.
