+Version 2.1.1
+
+* New ISO C 9x function _exit, imaxabs, and imaxdiv are added.
\f
Version 2.1
+* Richard Henderson corrected size of struct timeval on Linux/Alpha to
+ conform to POSIX member type requirements. Symbol versions have been
+ adjusted as needed within the library, and for direct use by applications,
+ but there is potential for problems if third-party libraries use
+ struct timeval as part of their interface. This does not present
+ a problem for X and other "essential" system libraries.
+
* An additional locale model to support C++ Standard Library locale
model and probably more was implemented by Ulrich Drepper.
* 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
+* 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
+ numbers.
+
+* scanf recognizes the %a and %A format for scanning floating point numbers.
-* scanf recognizes the %A format for scanning floating point numbers
+* the new headers <stdint.h> and <inttypes.h> from ISO C 9X provides
+ information and interfaces for the available integer types.
-* the new header <inttypes.h> from ISO C 9X provides information and
- interfaces for the available integer types
+* about 130 new math functions were added to implement the ISO C9x math
+ library.
* the new header <complex.h> contains definitions of the complex math
- functions from ISO C 9X
+ functions from ISO C 9X.
+
+* the new header <tgmath.h> defines generic macros to use complex or
+ real valued functions.
+
+* Thorsten Kukuk provided an implementation for NIS+, securelevel 0, 1 and 2.
+
+* Andreas Jaeger provided a test suite for the math library.
-* 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.
+* Mark Kettenis implemented the utmpx interface and an utmp daemon.
-* Andreas Jaeger provided a test suite for the math library
+* Ulrich Drepper added character set conversion functions (iconv).
+
+* Optimized string functions have been added.
+
+* The localedata addon is now part of glibc.
+
+* An implementation of profiling shared libraries was added by Ulrich Drepper.
+
+* Thorsten Kukuk and Ulrich Drepper provided an implementation for a caching
+ daemon for NSS (nscd).
+
+ Missing a better place here are some numbers on improvements. Under
+ Linux 2.1.125 un-tar-ing the kernel sources takes
+
+ user system wall
+
+ using local files 12.19s 6.88s 22.91s
+
+ using NIS 13.92s 8.91s 26.34s
+
+ using NIS & nscd 10.37s 7.34s 25.30s
+
+ using NIS+ 27.57s 30.37s 640.46s
+
+ using NIS+ & nscd 10.25s 7.83s 26.51s
+
+ using NIS & old nscd [1] 13.83s 8.32s 29.60s
+
+ Keep in mind that non-namelookup related operations dominate above times.
+ It was just a common complain that using NIS+ unpacking the kernel is
+ horribly slow.
+
+ [1] The old nscd implementation is not available anymore since it was
+ distributed with glibc up to version 2.0.98 and thus is now replaced.
+
+* Tim Waugh provided an implementation of the POSIX.2 wordexp function family.
+
+* Mark Kettenis provided a Hesiod NSS module.
+
+* The ELF dynamic loader knows how to process dynamic string tokens ($ORIGIN
+ and $PLATFORM) in RPATHs and similar strings (Ulrich Drepper).
+
+* rcmd can now handle netgroups (Dick Streefland).
+
+* A port to the ARM was contributed by Phil Blundell, Pat Beirne and Scott
+ Bambrough.
+
+* Support for the IPv6 protocol has been added to the socket API, as per the
+ latest draft standards.
+
+* Support for Linux 2.2 has been added.
+
+* Interface changes relative to the latest 2.0.x release:

Version 2.0.2
Parts of the code were heavily modified by Ulrich Drepper to fit in the
NSS scheme used in glibc.
-* The new function `malloc_find_object_address' finds the starting address
- of a malloc'd block, given any address within the block;
- `malloc_object_allocated_size' returns the size of an allocated block;
- and `malloc_walk' lets you walk through all allocated blocks. These can
- be useful for debugging; see <malloc.h> for the interfaces.
-
* There is a new malloc debugging hook `__memalign_hook'.
* There are new typedefs `ushort' for `unsigned short int' and `uint' for
`make dvi' will produce a DVI file of the printed manual.
`make info' will produce Info files that you can read on line using C-h i
in Emacs or the `info' program.
- Please send comments on the manual to bug-glibc-manual@prep.ai.mit.edu.
+ Please send comments on the manual to bug-glibc-manual@gnu.org.
* The library now supports SVR4 on i386s (i386-unknown-sysv4).
