###########################################################################

Changes in 2.5.0: Released 25 May, 1999

 o  Change the handling of wtmp for GNU libc to use the Os-provided
    function updwtmp().

 o  Prevent some buffer overruns.

 o  Fix permissions on some files installed by RPM, add the log rotation
    control file.

 o  Change the seteuid() calls for fchown() and chown() for POSIXLY_CORRECT
    systems.

 o  pid file locking in ftpcount (ftpwho) is now consistent with the way
    the daemon locks these files.

 o  Cancel any pending alarm request to stop acl_remove() from being
    interrupted then called again via the SIGALRM handler, this should fix
    the flock on a bad file descriptor looping problem.

 o  Use %m in syslog format strings in place of %s and strerror(), this
    simplifies #ifdefs.

 o  For SCO, link ftpcount with libsocket, necessary as it now calls
    syslog().

 o  Added Redhat's RPM SPEC file for building RPMs.

 o  English corrections in ftpaccess manpage.  Technical correction: the
    noretrieve/allow-retrieve clauses do NOT support regular expressions.

 o  Move where ftpglob stuff is defined to avoid compilation errors on some
    systems.

 o  Port to SGI Irix version 4 corrected.

 o  Overwrite behavior on uploads has been made consistent with shell
    usage.  The daemon does not change ownership or permissions on
    overwrite.

 o  Corrected the PASV command to bind to the correct interface (local IP
    address).

 o  Removed the OVERWRITE and UPLOAD defines from platform config files;
    they are defined in the main config.h header.

 o  Issuing CWD without any parameters caused a signal 11, crashing the
    daemon.

 o  Port to HP/UX corrected.

 o  Added ERRATA file to discuss problems with getcwd().

 o  Added a portable version of the getcwd() function for systems which do
    not have it or imcorrectly implement it.  NextStep 3 uses this new
    function.

 o  OPIE support was being disabled even though the proper command-line
    switches were being set.  Corrected the use of opieverify().

 o  The fatal() function was not declared void; this was causing problems
    with some compilers.

 o  Port to Hitachi HI-UX corrected.

 o  Some calls to fnmatch() were missing parameters.

 o  Corrected the 'restricted' user feature.  It now works well with most
    FTP clients.

 o  Correct usage of -d vs -e in the install Makefile for a number of
    platforms.

 o  You can now use negated hostnames/addresses on the class ftpaccess
    clause.

 o  Added an ftpaccess clause to specify random text for the initial
    greeting:

        greeting text <message>

 o  Corrected password encryption/checking for Digital Unix with C2
    security (SECUREOSF).

 o  Merged the TODO file from the VR series with Stan's TODO file for the
    Academ betas.

 o  Changed the various permission denial messages sent by the daemon to
    the client to make it clear the message originated from the server.

 o  Ports to SCO, Solaris, uxw, ptx and isc corrected.

 o  Use the newer SEEK_ defines in place of the old BSD L_ defines and
    removed the global definition of entry, each function should define it
    locally.

 o  Removed an unnecessary lseek(L_SET) in ftpcount (ftpwho).

 o  Link ftpcount and ftpshut with ${XXLIBS}.

 o  Made strsep() definition consistent with BSD and Linux.  Add strsep()
    definition to conversions.c.

 o  Added #include <string.h> to ckconfig.c.

 o  Replaced the _PATH_DEVNULL define with a #include of "pathnames.h" in
    popen.c.

 o  Support long group access passwords if SecureWare or HPUX_10_TRUSTED
    are defined (using bigcrypt()).

 o  Fixed a memory leak in restrict.c.

 o  Digital Unix version 4 has a working getcwd(); use it instead of
    getwd().

 o  Stop restrict_list_check() from walking off the end of name.

 o  Added -x command-line option to mean 'log syslog+xferlog'.

 o  Changed the log ftpaccess clause to allow logging transfers to both the
    syslog and xferlog.  The log ftpaccess clauses now include:

        log syslog
        log xferlog
        log syslog+xferlog

 o  Formation of the WU-FTPD Development Group on 1 April, 1999.
    2.4.2-VR17 chosen as initial baseline for the daemon.

Changes in 2.4.2-VR17: Released 1 April, 1999

 o  Gregory A Lundberg resigns as the de-facto maintainer of WU-FTPD.  "And
    you thought I was joking."

 o  VIRTUAL is now the default for Solaris; all Solaris systems support
    multiple interfaces (IP addresses).

 o  Fixed complaints involving virtual_len reported by several beta
    testers.

 o  Some of the 'C' source code in ftpcmd.y depended upon a particular
    behavior when ANSI/ISO does not define it.  Corrected so all compilers
    will properly interpret the code.

 o  Corrected the support for QUOTA on Solaris.

 o  The GNU EGCS 'C' compiler is broken.  A quick check and we can avoid
    the brokenness.

 o  Port to Ultrix corrected.

 o  The default shell on NextStep wants -d instead of -e.  Changed to test
    instead of [] since that's more portable; will probably do the same to
    other systems in a future release.

 o  MNTMAXSTR was possibly undefined on Digital Unix 4.0 even when not
    using QUOTA_DEVICE, causing compilation errors.

 o  Added daemonaddress to the ftpaccess manpage.

 o  Added a note from Chad Price <[e-mail]> in src/logwtmp.c
    about the brokenness of Solaris' last command.

 o  It turns out that not all SunOS 4.1 boxes actually have a getcwd()
    function.

 o  The labels unix and __unix__ are depricated on BSD, effecting the logic
    for the reponse to the SYST command.

 o  Added an appnote about OPIE.  See src/makefiles/Makefile.lnx for a way
    to automatically have the daemon use OPIE.  Send your Makefile if you
    do something similar for your system.

 o  Added an appnote about a problem experienced with Trusted Solaris.

 o  Added doc/misc directory to start collecting interesting tidbits which
    may help people get their servers going.

 o  The FIXES files were really cluttering up the base directory.  Moved
    them to a directory under doc.

 o  The 'log security' ftpaccess clause covered all but a few messages
    about filesystem operations.  It now covers the few it missed.

 o  Under some conditions _PATH_WTMP was not being set in pathnames.h

 o  QUOTA is now supported for Solaris.

 o  Trusted Solaris needed additional functionality in ftpcount (ftpwho).

 o  File locking in ftpcount (ftpwho) was never completed.

 o  Port to HP/UX corrected.

 o  'make install' now accepts DESTDIR to install into a directory
    structure other than the root file system.  A number of other optional
    parameters are available to override the default ownership of the
    installed files.  Missing directories are automatically created.  File
    permisssions were reduced to the minimum necessary.

 o  Dead code removed.

 o  The Makefile for Linux now automatically detects if PAM is installed
    and compiles the daemon to use it.

 o  Fix an uninitialized variable in ftpshut which could effect the way the
    command works with default values.

 o  Suppress trailing blanks from the output of a wide 'ps' in the ftpcount
    (ftpwho) command.  Just making things pretty.

 o  Updated upload.configuration.HOWTO to describe more of the
    configuration having to do with class= rules and overwrite, delete and
    rename clauses.

 o  Added vers.c and edit to 'make cleandir' in the src directory.  These
    files are automatically created during the build process.

 o  Added a restrict_check(".") in the LIST command for consistency with
    the remainder of the code in ftpcmd.y.

 o  Corrected the 'restricted' users feature so it would play nicely with
    web clients and the way some of them mis-interpret FTP URLs.

###########################################################################

Changes in 2.4.2-VR16: Released 4 March, 1999

 o  The Makefile for hiu had a typo and would not install two manpages.

 o  Merged 2.4.2-BETA-18-VR15 with 2.4.2 (final) from Academ.  Gotta love
    CVS. :)

 o  Gregory A Lundberg becomes the de-facto maintainer of WU-FTPD pending
    the formation of the WU-FTPD Development Group.

###########################################################################

Changes in 2.4.2: Released 26 Febraury, 1999 (not announced)

 o  With the release of 2.4.2, Stan Barber steps down as the maintainer of
    WU-FTPD.

 o  Documented that 'upload .. no' allowed directory creation.  See
    doc/examples/ftpaccess.heavy as an example.  [Ed: This is not the case
    for the VR series, but I'm including the change anyway.]

 o  Clarification in the manpage for ftphosts: ftp or anonymous listed in
    the file will disable anonymous ftp access.

 o  Possible pointer overrun in acl.c parsing ftpaccess corrected.

 o  Literal constant in ftpcmd.y changed to static to reduce program size.

 o  ftpcount/ftpwho interpretation of start/stop times made to match the
    way the daemon actually does it.

 o  setproctitle() in ftpd.c updated to avoid a buffer overrun and handle
    low memory conditions; SCO corrections.

 o  Possible buffer overrun parsing 'virtual root' and 'virtual logfile'
    corrected.

 o  A timeout timer was being reset at the wrong point during STOR.

 o  Corrections for Sun/Solaris paths in pathnames.h.

 o  Makefile for DEC/Unix (dec and du4) changed from cc -std1 to cc -std.

 o  Correction in syslog support for DEC/Unix in support/syslog.c.

 o  util/xferstats corrected to parse your local domain name rather than
    just assuming you're academ.com.

 o  Other changes are white-noise or simply for style and do not effect the
    operation of the daemon in any way.

###########################################################################

Changes in 2.4.2-BETA-18-VR15: Released 1 March, 1999

 o  Provided a means to completely disable anonymous FTP access.  Done as a
    compile-time option, see config.h

 o  NLST with a directory ending with / doubled up the slash.  This had
    been there for years.

 o  Completed large file support for AIX.  To enable Large File support,
    use './build aix LF=YES'

 o  The stock compiler on SunOS 4.1 is breaindead.  Use gcc instead.  Also
    found during trials that getcwd() works fine on s41 and enabled it.
    Found that on a SunOS 4.1 using NFS in the FTP area, fchdir() doesn't
    always work so if you have problems, #define HAS_NO_FCHDIR to see if
    that helps.

 o  Complete the changeover from SCO Unix to SCO OpenServer 5.

 o  We really don't need to #undef NO_PRIVATE twice in config.h .. it just
    confuses things.

 o  The -X command-line option and 'log syslog' were not working as
    documented.  The switch was re-initialized by the 'log' clauses.

 o  Additional corrections for AIX 4.2 and large file support.  Earlier
    versions of AIX may need to edit support/makefiles/Makefile.aix if they
    don't have snprintf() or strdup().

 o  Corrected a case where _PATH_XFERLOG may not be defined at all in
    src/pathnames.h.

 o  Code cleanup for the xferlog print which was changed in VR14.

 o  A typo selected the wrong HELP_CRACKERS patch in one place.

 o  Protect a #define conflict on NetBSD with #ifndef.

 o  The reason the daemon won't work on AIX is the size_t_blksize change
    made as an experiment way-back-when.  Backed out that change.  Let's
    see what happens.
