ABI Changelog
==============
This changelog contains information about ABI changes in libc++. Specifically
the addition and deletion of symbols from the libc++ dylib.
Each entry should start with the revision number followed by a description of
the change. The entry should contain a summary of the ABI changes made,
including what symbols were added, removed, or changed.
To generate a summary use "sym_diff.py" diffing against the appropriate ABI list.
Afterwards the ABI list should be updated to include the new changes.
New entries should be added directly below the "Version" header.
-----------
Version 5.0
-----------
* r296729 - Remove std::num_get template methods which should be inline
These functions should never have had visible definitions in the dylib but
since they were previously not specified with 'inline' they accidentally
got emitted. This change is non-ABI breaking because every "linkage unit"
must contain its own definition.

No changes
* r285101 - Add -fvisibility-inlines-hidden when building libc++.
Although this change removes symbols, it should still be non-ABI breaking
since all of the definitions removed are inline functions. For this reason
removing these symbols is safe because every "linkage unit" which uses these
functions will contain their own definition.
