Date        Modules         Changes

2008-09-28  sockets         When using this module, you now need to link with
                            $(LIBSOCKET).

2008-09-24  sys_select      The limitation on `select', introduced 2008-09-23,
                            was removed.  sys_select now includes a select
                            wrapper for Winsock.  The wrapper expects socket
                            and file descriptors to be compatible as arranged
                            by the sys_socket on MinGW.

2008-09-23  sys_socket      Under Windows (MinGW), the module now adds
                            wrappers around Winsock functions, so that
                            socket descriptors are now compatible with
                            file descriptors.  In general, this change
                            will simply improve your code's portability
                            between POSIX platforms and Windows.  In
                            particular, you will be able to use ioctl and
                            close instead of ioctlsocket and closesocket, 
                            and test errno instead of WSAGetLastError ().
                            On the other hand, you have to audit your code to
                            remove usage of these Winsock-specific functions.

                            This change does not remove the need to call
                            the gl_sockets_startup function from the sockets
                            gnulib module.  Also, for now select is disabled
                            when you include the sys_socket module; while
                            the functionality will be restored soon, for
                            efficiency it is suggested to use the poll system
                            poll system call and gnulib module instead.

2008-09-13  EOVERFLOW       The module is removed. Use module errno instead.

2008-09-01  filename        The module does not define the function
                            concatenated_filename any more. To get an
                            equivalent function, use function
                            xconcatenated_filename from module
                            'xconcat-filename'.

2008-08-31  havelib         On Solaris, when searching for 64-bit mode
                            libraries the directory $prefix/lib is now ignored.
                            Instead the directory $prefix/lib/64 is searched.
                            You may need to create a symbolic link for
                            $prefix/lib/64 if you have 64-bit libraries
                            installed in $prefix/lib.

2008-08-19  strverscmp      The include file is changed from "strverscmp.h"
                            to <string.h>.

2008-08-14  lock            The include file is changed from "lock.h"
                            to "glthread/lock.h".
            tls             The include file is changed from "tls.h"
                            to "glthread/tls.h".

2008-07-17  c-stack         The module now requires the addition of
                            $(LIBCSTACK) or $(LTLIBCSTACK) in Makefile.am,
                            since it may depend on linking with libsigsegv.

2008-07-07  isnanf-nolibm   The include file is changed from "isnanf.h"
                            to "isnanf-nolibm.h".
            isnand-nolibm   The include file is changed from "isnand.h"
                            to "isnand-nolibm.h".

2008-06-10  execute         The execute function takes an additional termsigp
                            argument. Passing termsigp = NULL is ok.
            wait-process    The wait_subprocess function takes an additional
                            termsigp argument. Passing termsigp = NULL is ok.

2008-05-10  linebreak       The module is split into several modules unilbrk/*.
                            The include file is changed from "linebreak.h" to
                            "unilbrk.h". Two functions are renamed:
                            mbs_possible_linebreaks -> ulc_possible_linebreaks
                            mbs_width_linebreaks -> ulc_width_linebreaks

2008-04-28  rpmatch         The include file is now <stdlib.h>.

2008-04-28  inet_ntop       The include file is changed from "inet_ntop.h"
                            to <arpa/inet.h>.

2008-04-28  inet_pton       The include file is changed from "inet_pton.h"
                            to <arpa/inet.h>.

2008-03-06  freadahead      The return value's computation has changed. It
                            now increases by 1 after ungetc.

2008-01-26  isnan-nolibm    The module name is changed from isnan-nolibm to
                            isnand-nolibm. The include file is changed from
                            "isnan.h" to "isnand.h". The function that it
                            defines is changed from isnan() to isnand().

2008-01-14  strcasestr      This module now replaces worst-case inefficient
                            implementations; clients that use controlled
                            needles and thus do not care about worst-case
                            efficiency should use the new strcasestr-simple
                            module instead for smaller code size.

2008-01-09  alloca-opt      Now defines HAVE_ALLOCA_H only when the system
                            supplies an <alloca.h>.  Gnulib-using code is now
                            expected to include <alloca.h> unconditionally.
                            Non-gnulib-using code can continue to include
                            <alloca.h> only if HAVE_ALLOCA_H is defined.

2008-01-08  memmem          This module now replaces worst-case inefficient
                            implementations; clients that use controlled
                            needles and thus do not care about worst-case
                            efficiency should use the new memmem-simple
                            module instead for smaller code size.

2007-12-24  setenv          The include file is changed from "setenv.h" to
                            <stdlib.h>. Also, the unsetenv function is no
                            longer declared in this module; use the 'unsetenv'
                            module if you need it.

2007-12-03  getpagesize     The include file is changed from "getpagesize.h"
                            to <unistd.h>.

2007-12-03  strcase         The include file is changed from <string.h> to
                            <strings.h>.

2007-10-07  most modules    The license for most modules has changed from
                            GPLv2+ to GPLv3+, and from LGPLv2+ to LGPLv3+.
                            A few modules are still under LGPLv2+; see the
                            module description for the applicable license.

2007-09-01  linebreak       "linebreak.h" no longer declares the functions
                            locale_charset, uc_width, u{8,16,32}_width. Use
                            "uniwidth.h" to get these functions declared.

2007-08-28  areadlink-with-size
                            Renamed from mreadlink-with-size.
                            Function renamed: mreadlink_with_size ->
                            areadlink_with_size.

2007-08-22  getdelim, getline
                            The include file is changed from "getdelim.h"
                            and "getline.h" to the POSIX 200x <stdio.h>.

2007-08-18  idcache         Now provides prototypes in "idcache.h".

2007-08-10  xstrtol         The STRTOL_FATAL_ERROR macro is removed.
                            Use the new xstrtol_fatal function instead.

2007-08-04  human           The function human_options no longer reports an
                            error to standard error; that is now the
                            caller's responsibility.  It returns an
                            error code of type enum strtol_error
                            instead of the integer option value, and stores
                            the option value via a new int * argument.
            xstrtol         The first two arguments of STRTOL_FATAL_ERROR
                            are now an option name and option argument
                            instead of an option argument and a type string,
                            STRTOL_FAIL_WARN is removed.

2007-07-14  gpl, lgpl       New Texinfo versions with no sectioning commands.

2007-07-10  version-etc     Output now mentions GPLv3+, not GPLv2+.  Use
                            gnulib-tool --local-dir to override this.

2007-07-07  wcwidth         The include file is changed from "wcwidth.h" to
                            <wchar.h>.

2007-07-02  gpl, lgpl       Renamed to gpl-2.0 and lgpl-2.1 respectively.
                            (There is also a new module gpl-3.0.)

2007-06-16  lchown          The include file is changed from "lchown.h" to
                            <unistd.h>.

2007-06-09  xallocsa        Renamed to xmalloca. The include file "xallocsa.h"
                            was remamed to "xmalloca.h". The function was
                            renamed:
                              xallocsa -> xmalloca

2007-06-09  allocsa         Renamed to malloca. The include file "allocsa.h"
                            was remamed to "malloca.h". The function-like
                            macros were renamed:
                              allocsa -> malloca
                              freesa -> freea

2007-05-20  utimens         Renamed futimens to gl_futimens, to avoid
                            conflict with the glibc-2.6-introduced function
                            that has a different signature.

2007-05-01  sigprocmask     The module now depends on signal, so replace
                              #include "sigprocmask.h"
                            with
                              #include <signal.h>

2007-04-06  gettext         The macro HAVE_LONG_DOUBLE is no longer set.
                            You can replace all its uses with 1, i.e. assume
                            'long double' as a type exists.

2007-04-01  arcfour         Renamed to crypto/arcfour.
            arctwo          Renamed to crypto/arctwo.
            des             Renamed to crypto/des.
            gc              Renamed to crypto/gc.
            gc-arcfour      Renamed to crypto/gc-arcfour.
            gc-arctwo       Renamed to crypto/gc-arctwo.
            gc-des          Renamed to crypto/gc-des.
            gc-hmac-md5     Renamed to crypto/gc-hmac-md5.
            gc-hmac-sha1    Renamed to crypto/gc-hmac-sha1.
            gc-md2          Renamed to crypto/gc-md2.
            gc-md4          Renamed to crypto/gc-md4.
            gc-md5          Renamed to crypto/gc-md5.
            gc-pbkdf2-sha1  Renamed to crypto/gc-pbkdf2-sha1.
            gc-random       Renamed to crypto/gc-random.
            gc-rijndael     Renamed to crypto/gc-rijndael.
            gc-sha1         Renamed to crypto/gc-sha1.
            hmac-md5        Renamed to crypto/hmac-md5.
            hmac-sha1       Renamed to crypto/hmac-sha1.
            md2             Renamed to crypto/md2.
            md4             Renamed to crypto/md4.

            sha1            Renamed to crypto/sha1.

2007-03-27  vasprintf       The module now depends on stdio, so replace
                               #include "vasprintf.h"
                            with
                               #include <stdio.h>

2007-03-24  tsearch         The include file is changed from "tsearch.h" to
                            <search.h>.

2007-03-24  utf8-ucs4       The include file is changed from "utf8-ucs4.h"
                            to "unistr.h".
            utf8-ucs4-unsafe  The include file is changed from
                            "utf8-ucs4-unsafe.h" to "unistr.h".
            utf16-ucs4      The include file is changed from "utf16-ucs4.h"
                            to "unistr.h".
            utf16-ucs4-unsafe  The include file is changed from
                            "utf16-ucs4-unsafe.h" to "unistr.h".
            ucs4-utf8       The include file is changed from "ucs4-utf8.h"
                            to "unistr.h".
            ucs4-utf16      The include file is changed from "ucs4-utf16.h"
                            to "unistr.h".

2007-03-19  iconvme         The module is removed. Use module striconv instead:
                            iconv_string -> str_iconv
                            iconv_alloc -> str_cd_iconv (with reversed
                                           arguments)

2007-03-15  list            The functions gl_list_create_empty and
            array-list      gl_list_create now take an extra fourth argument.
            carray-list     You can pass NULL.
            linked-list
            linkedhash-list
            avltree-list
            rbtree-list
            avltreehash-list
            rbtreehash-list

2007-03-15  oset            The function gl_oset_create_empty now takes a
            array-oset      third argument. You can pass NULL.
            avltree-oset
            rbtree-oset

2007-03-12  des             The types and functions in lib/des.h have been
            gc-des          renamed:

                            des_ctx -> gl_des_ctx, tripledes_ctx -> gl_3des_ctx,
                            des_is_weak_key -> gl_des_is_weak_key,
                            des_setkey -> gl_des_setkey,
                            des_makekey -> gl_des_makekey,
                            des_ecb_crypt -> gl_des_ecb_crypt,
                            des_ecb_encrypt -> gl_des_ecb_encrypt,
                            des_ecb_decrypt -> gl_des_ecb_decrypt,
                            tripledes_set2keys -> gl_3des_set2keys,
                            tripledes_set3keys -> gl_3des_set3keys,
                            tripledes_makekey -> gl_3des_makekey,
                            tripledes_ecb_crypt -> gl_3des_ecb_crypt.
