-Version 1.10
+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.
+
+* 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 and %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.
+
+* 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.
+
+* 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.
+
+* Mark Kettenis implemented the utmpx interface and an utmp daemon.
+
+* 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:

+\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
+\f
+Version 2.0
+
+* GNU extensions are no longer declared by default. To enable them you
+ must define the macro `_GNU_SOURCE' in your program or compile with
+ `-D_GNU_SOURCE'.
* The library has changed from using GNU ld symbol aliases to using weak
symbols where available. The ELF object file format supports weak
symbols; GNU ld also supports weak symbols in the a.out format. (There
is also now support for other GNU ld extensions in ELF. Use the
- `--with-elf' option to configure to indicate you have elf, and
- `--with-gnu-ld' if using GNU ld.) This changed resulted in the deletion
+ `--with-elf' option to configure to indicate you have ELF, and
+ `--with-gnu-ld' if using GNU ld.) This change resulted in the deletion
of many files which contained only symbol aliases, reducing the size of
the source and the compiled library; many other files were renamed to
less cryptic names previously occupied by the symbol alias files.
+ There is a new header file <elf.h> for programs which operate on
+ files in the ELF format.
+
+* Converted to Autoconf version 2, so `configure' has more options.
+ Run `configure --help' to see the details.
+
+* The library can now be configured to build profiling, highly-optimized
+ (but undebuggable), and/or shared libraries (ELF with GNU ld only). The
+ `--enable-profile', `--enable-omitfp', and `--enable-shared' options to
+ `configure' enable building these extra libraries. The shared library is
+ built by default when using both ELF and GNU ld. When shared libraries
+ are enabled, the new library `-ldl' is available for arbitrary run-time
+ loading of shared objects; its interface is defined in <dlfcn.h>. The
+ new header file <link.h> gives access to the internals of the run-time
+ dynamic linker, `ld.so'. The shell script `ldd' is similar to the
+ application of same name on other systems and it provides information
+ about dynamically linked binaries.
+
+* The C library now provides the run-time support code for profiling
+ executables compiled with `-pg'. Programs can control the profiling code
+ through the interface in <sys/gmon.h>. The `gmon.out' files written by
+ the GNU C library can be read only by GNU `gprof' (from GNU binutils);
+ the support for this file format was contributed by David Mosberger-Tang.
+
+* The math code has been replaced with a math library based on fdlibm from
+ Sun, and modified by JT Conklin and Ulrich Drepper with i387 support, by
+ Ian Taylor with `float' functions and by Ulrich Drepper with `long double'
+ functions. The math functions now reside in a separate library, so
+ programs using them will need to use `-lm' their linking commands.
+
+* John C. Bowman contributed optimized ix87 assembler inline functions.
+
+* Ulrich Drepper has contributed support for an `/etc/nsswitch.conf'
+ mechanism similar to that found in Solaris 2. This is now used for the
+ group, passwd, hosts, networks, services, protocols, rpc, ethers,
+ shadow, netgroup, publickey, and alias databases. The `nsswitch.conf'
+ file controls what services are used for each individual database. This
+ works by loading shared libraries with names specified in `nsswitch.conf',
+ so service modules can be changed or added at any time without even
+ relinking any program. Currently there are the file, db, and NIS based
+ NSS services available.
+
+* The new functions `strtoq' and `strtouq' parse integer values from
+ strings, like `strtol' and `strtoul', but they return `long long int' and
+ `unsigned long long int' values, respectively (64-bit quantities).
+
+* The new functions `strtof' and `strtold' parse floating-point values from
+ strings, like `strtod', but they return `float' and `long double' values,
+ respectively (on some machines `double' and `long double' are the same).
+
+* Ulrich Drepper has contributed new implementations of the floating-point
+ printing and reading code used in the `printf' family of functions and
+ `strtod', `strtof', and `strtold'. These new functions are perfectly
+ accurate, and much faster than the old ones.
+
+* The implementation of the POSIX locale model was completely rewritten by
+ Ulrich Drepper. This includes the new programs `localedef' and `locale'
+ to compile the POSIX locale definition.
+
+* The former dummy implementations of the strcoll and strxfrm function are
+ now replaced by fully functional code contributed by Ulrich Drepper. The
+ collation information comes from the POSIX locale definitions.
+
+* The new header <langinfo.h> defines an interface for accessing
+ various locale-dependent data (using the locale chosen with `setlocale').
+
+* Ulrich Drepper has contributed a new suite of functions for operation on
+ wide-character and multibyte-character strings, in <wchar.h>;
+ and classification and case conversion of wide characters, in <wctype.h>.
+ These new functions are conforming to the ISO C, Amendement 1 specification.
+
+* There is now a second implementation of the standard I/O library available.
+ It comes from GNU libg++ as was written by Per Bothner, heavily modified
+ by Hongjiu Lu and made thread safe by Ulrich Drepper.
+
+* You can now use positional parameter specifications in format strings
+ for the `printf' and `scanf' families of functions. For example,
+ `printf ("Number %2$d, Mr %1$s\n", "Jones", 6);'' prints
+ ``Number 6, Mr Jones''. This is mainly useful when providing different
+ format strings for different languages, whose grammars may dictate
+ different orderings of the values being printed. To support this
+ feature, the interface for `register_printf_handler' has changed; see
+ the header file <printf.h> for details.
+
+* The `printf' and `scanf' families of functions now understand a new
+ formatting flag for numeric conversions: the ' flag (e.g. %'d or %'f) says
+ to group numbers as indicated by the locale; for `scanf' and friends, this
+ says to accept as valid only a number with all the proper grouping
+ separators in the right places. In the default "C" locale, numbers are
+ not grouped; but locales for specific countries will define the usual
+ conventions (i.e. separate thousands with `,' in the US locale).
* The pgrp functions have been regularized, slightly incompatibly but much
less confusingly. The core functions are now `getpgid' and `setpgid',
* The new header file <fts.h> and suite of functions simplify programs that
operate on directory trees. This code comes from 4.4 BSD.
-* Converted to Autoconf version 2, so `configure' has more options.
- Run `configure --help' to see the details.
-
-* The resolver code has been updated from the BIND-4.9.3-BETA14 release.
-
-* The new function `malloc_find_object_address' finds the starting address
- of a malloc'd block, given any address within the block. This can be
- useful for debugging.
-
-* The new functions `strtoq' and `strtouq' parse integer values from
- strings, like `strtol' and `strtoul', but they return `long long int' and
- `unsigned long long int' values, respectively (64-bit quantities).
+* The resolver code has been updated from the BIND 4.9.5-P1 release.
+ Parts of the code were heavily modified by Ulrich Drepper to fit in the
+ NSS scheme used in glibc.
* There is a new malloc debugging hook `__memalign_hook'.
* The `-lmcheck' library to enable standard malloc debugging hooks is now
done differently, so that it works even without GNU ld.
+
+* New function `euidaccess' checks allowed access to a file like `access',
+ but using the effective IDs instead of the real IDs.
+
+* The time zone data files have been updated for the latest and greatest
+ local time conventions of the countries of the world.
+
+* The new function `dirfd' extracts the file descriptor used by a DIR stream;
+ see <dirent.h>.
+
+* The new functions `ecvt', `fcvt', and `gcvt' provide an obsolete interface
+ for formatting floating-point numbers. They are provided only for
+ compatibility; new programs should use `sprintf' instead. There are
+ also equivalent function for the `long double' floating-point type and
+ all functions also exist in a reentrant form.
+
+* The new auxiliary library `-lutil' from 4.4 BSD contains various
+ functions for maintaining the login-record files (primarily of use to
+ system programs such as `login'), and convenient functions for
+ allocating and initializing a pseudo-terminal (pty) device.
+
+* Ulrich Drepper has contributed new support for System V style
+ shared memory and IPC on systems that support it.
+
+* Ulrich Drepper has contributed several miscellaneous new functions found
+ in System V: The `hsearch' family of functions provide an effective
+ implementation of hash tables; `a64l' and `l64a' provide a very simple
+ binary to ASCII mapping; `drand48' and friends provide a 48-bit random
+ number generator.
+
+* Ulrich Drepper has contributed new reentrant counterparts for the
+ `random' and `hsearch' families of functions; `random_r', `hsearch_r', etc.
+
+* Ulrich Drepper has contributed new, highly-optimized versions of several
+ string functions for the i486/Pentium family of processors.
+
+* Ulrich Drepper has updated the Linux-specific code, based largely
+ on work done in Hongjiu Lu's version of GNU libc for Linux.
+ The GNU library now supports Linux versions 2.0.10 and later,
+ using the ELF object file format (i[3456]86-*-linux).
+
+* Andreas Schwab has ported the C library to Linux/m68k (m68k-*-linux).
+
+* David Mosberger-Tang and Richard Henderson have ported the C library
+ to Linux/Alpha (alpha-*-linux). Richard Henderson contributed the
+ dynamic linking support for ELF/Alpha.
+
+* Richard Henderson contributed several Alpha optimized assembler function
+ for arithmetic and string handling.
+
+* Ulrich Drepper has contributed a new set of message catalog functions to
+ support multiple languages using the <libintl.h> interface, for use with
+ his new package GNU gettext. Translation volunteers have contributed
+ catalogs of the library's messages in Spanish, German, and Korean.
+
+* For compatibility with XPG4, Ulrich Drepper has contributed the `gencat'
+ program and the `catgets' function for reading the catalog files it
+ creates. (The <libintl.h> interface is preferred; we include the
+ <nl_types.h> interface using `catgets' only for source compatibility with
+ programs already written to use it.)
+
+* New header file <values.h> gives SVID-compatible names for <limits.h>
+ constants.
+
+* Various new macros, declarations, and small header files for compatibility
+ with 4.4 BSD.
+
+* New function `group_member' is a convenient way to check if a process has
+ a given effective group ID.
+
+* When using GCC 2.7 and later, the socket functions are now declared in a
+ special way so that passing an argument of type `struct sockaddr_in *',
+ `struct sockaddr_ns *', or `struct sockaddr_un *' instead of the generic
+ `struct sockaddr *' type, does not generate a type-clash warning.
+
+* New function `error' declared in header file <error.h> is a convenient
+ function for printing error messages and optionally exiting; this is the
+ canonical function used in GNU programs. The new functions `err', `warn',
+ and friends in header file <err.h> are the canonical 4.4 BSD interface for
+ doing the same thing.
+
+* The <glob.h> interface has several new flags from 4.4 BSD that extend the
+ POSIX.2 `glob' function to do ~ and {...} expansion.
+
+* New function `unsetenv' complements `setenv' for compatibility with 4.4 BSD.
+ `clearenv' which is used in POSIX.9 is also available.
+
+* New function `getsid' returns session ID number on systems that support it.
+
+* We have incorporated the 4.4 BSD `db' library (version 1.85). New header
+ files <db.h> and <mpool.h> provide a rich set of functions for several
+ types of simple databases stored in memory and in files, and <ndbm.h> is
+ an old `ndbm'-compatible interface using the `db' functions. Link with
+ `-ldb' to get these functions.
+
+* New macro `strdupa' copies a string like `strdup', but uses local stack
+ space from `alloca' instead of dynamic heap space from `malloc'.
+
+* New function `strnlen' is like `strlen' but searches only a given maximum
+ number of characters for the null terminator. `stpncpy', `strndup' and
+ `strndupa' are similar variants for the `stpcpy', `strdup' and `strdupa'
+ function.
+
+* New function `statfs' in header <sys/statfs.h>.
+
+* The new <argz.h> and <envz.h> interfaces contributed by Miles Bader
+ provide convenient functions for operating on blocks of null-terminated
+ strings.
+
+* A new suite of functions in <utmp.h> handle all the details of reading
+ and writing the utmp file.
+
+* An implementation of the NIS/YP(tm) based NSS service was contributed by
+ Thorsten Kukuk.
+
+* Paul Eggert and Ulrich Drepper modified the `strftime' function to be
+ completely POSIX compliant and also implemented the extended functionality
+ to handle alternate digit representation and alternate era date formats.
+
+* Ulrich Drepper provided an implementation of the `strptime' function
+ defined in XPG4.2 which transforms a string into a `struct tm' value.
+
+* Paul Eggert provided the tzselect shell script as part of the timezone
+ code. The shell script makes it easy to select the correct timezone
+ specification.
+
+* The implementation of the malloc family of functions is completely replaced
+ by a new implementation by Doug Lea with many improvements by Wolfram Gloger.
+ The implementation uses the mmap function (if available) and it is
+ optimized for the use in multi threaded programs.
+
+* Ulrich Drepper contributed a MD5 "encryption" for the crypt family of
+ functions. This new functionality is usable by specifying a special
+ salt string and it is compatible with implementation on *BSD systems.
+
+* Lots of functions from the XPG4.2 standard were added by Ulrich Drepper:
+ `getsubopt' to handle second level command line options, `bsd_signal'
+ to access BSD style `signal' functionality, the obsolete `regexp' style
+ expression matcher.
+
+* the `lchown' function is available on system which support this
+ functionality.
+
+* The implementation of the shadow password handling function was contributed
+ by Ulrich Drepper.
+
+* David Mosberger-Tang changed the SunRPC implementation to be 64bit safe.
+
+* POSIX.1g support was added. The <sys/select.h> header is available,
+ `isfdtype' and `pselect' are implemented. Craig Metz contributed an
+ implementation of `getaddrinfo'.
