 == Boost 1.69
 
 Boost has been upgraded to version 1.69. See the xref:developers/Development_Boost.adoc[Boost section] for details.
+
+== The GNU C Library version 2.29
+
+Fedora 30 provides the GNU C Library - `glibc` - version 2.29. Notable changes include:
+
+=== New features
+
+* The `getcpu` wrapper function has been added, which returns the currently used CPU and NUMA node.
+* Optimized generic `exp`, `exp2`, `log`, `log2`, `pow`, `sinf`, `cosf`, `sincosf` and `tanf`.
+* The `reallocarray` function is now declared under `_DEFAULT_SOURCE`, not just for `_GNU_SOURCE`, to match BSD environments.
+* The `popen` and `system` do not run `atfork` handlers anymore.
+* `strftime`'s default formatting of a locale's alternative year (`%Ey`) has been changed to zero-pad the year to a minimum of two digits, like `%y`.
+* As a GNU extension, the `_` and `-` flags can now be applied to `%EY` to control how the year number is formatted; they have the same effect that they would on `%Ey`.
+
+=== Deprecated and removed features
+
+* The `glibc.tune` tunable namespace has been renamed to `glibc.cpu` and the tunable `glibc.tune.cpu` has been renamed to `glibc.cpu.name`.
+* An archaic GNU extension to `scanf`, under which `%as`, `%aS`, and `%a[...]` meant to scan a string and allocate space for it with `malloc`, is now restricted to programs compiled in C89 or C++98 mode with `_GNU_SOURCE` defined.
