 Major new features:
 
+* All functionality formerly implemented in the libraries libpthread,
+  libdl, libutil, libanl has been integrated into libc.  New
+  applications do not link with -lpthread, -ldl, -lutil, -lanl anymore.
+  For backwards compatibility, empty static archives libpthread.a,
+  libdl.a, libutil.a, libanl.a are provided, so that the linker options
+  keep working.  Applications which have been linked against glibc 2.33
+  or earlier continue to load the corresponding shared objects (which
+  are now empty).  The integration of those libraries into libc means
+  that additional symbols become available by default.  This can cause
+  applications that contain weak references to take unexpected code
+  paths that would only have been used in previous glibc versions when
+  e.g. preloading libpthread.so.0, potentially exposing application
+  bugs.
+
 * When _DYNAMIC_STACK_SIZE_SOURCE or _GNU_SOURCE are defined,
   PTHREAD_STACK_MIN is no longer constant and is redefined to
   sysconf(_SC_THREAD_STACK_MIN).
