@@ -34,7 +34,9 @@ Major new features:
* On powerpc64*, glibc can now be compiled without scv support using the
--disable-scv configure option.
-* Add support for 64-bit time_t for ABIs with defaults currently unchanged.
+* Add support for 64-bit time_t on configurations like x86 where time_t
+ is traditionally 32-bit. Although time_t still defaults to 32-bit on
+ these configurations, this default may change in future versions.
This is enabled with the _TIME_BITS preprocessor set to 64 and only
supported when LFS (_FILE_OFFSET_BITS=64) is also enabled. It is only
enabled for Linux and the full support requires a minimum version of 5.1.
