+Version 2.1
+
+* An additional locale model to support C++ Standard Library locale
+  model and probably more was implemented by Ulrich Drepper.
+
+* Eric Youngdale and Ulrich Drepper implemented versioning of objects on
+  symbol level.
+
+* Miles Bader provided the `argp' function family to support hierachical
+  command line argument parsing, layered on top of getopt.
+
+* strtod accepts new hexadecimal floating-point format from ISO C 9X
+
+* printf has two new specifiers %a and %A to print hexadecimal flaoting-point
+  numbers
+
+* scanf recognizes the %A format for scanning floating point numbers
+
+* the new header <inttypes.h> from ISO C 9X provides information and
+  interfaces for the available integer types
+
+* the new header <complex.h> contains definitions of the complex math
+  functions from ISO C 9X
+
+* Thorsten Kukuk provided an implementation for NIS+, securelevel 0 and 1.
+  The implementation for securelevel 2 will follow as soon as the Diffie-
+  Hellman patent expired.
+
+* Andreas Jaeger provided a test suite for the math library
+\f
+Version 2.0.2
+
+* more bug fixes
+
+* add atoll function
+
+* fix complex problems in Berkeley DB code
+
+* fix math functions
+\f
+Version 2.0.1
+
+* fixed lots of header problems (especially Linux/GNU specific)
+
+* dynamic loader preserves all registers
+
+* Roland McGrath provided support for handling of auxiliary objects in
+  the ELF dynamic loader.
+
+* support for parallel builds is improved
