Release 1.6
(01/27/91)

    1. The installation and operation of the door has changed substantially.
       I suggest you delete your old SIGDOOR (after backing it up!) and
       install the new one fresh.

    2. The keyword search now asks if the search is for full words only. If
       so, only full words will match. Otherwise the text will match
       anywhere, even within a word. The keyword search also now supports
       the new lower case diskette descriptions.

    3. Since the diskettes are now already ZIPped, "preparing a diskette" 
       simply copies the diskette to the download directory. PKZIP is no
       longer used.

    4. The DODINDEX.DAT and LIBDEF files have been updated for the 9th
       edition (December 1990) of the PC SIG Library on CD ROM.

    5. The SIGDOOR.CNF file has been re-organized and simplified. You no
       longer specify the names of the menu files.

    6. The way of dealing with menus has been changed. In previous
       releases, some menus were imbedded in the program, and some were
       built based on external files (CATMENU and INFOMENU). Now all menus
       are contained in external files (MAINMENU, INFOMENU, SRCHMENU, and
       CATMENU). @ and @X variables are supported, as well as the 'G'
       file extension. INFOMENU.LST and CATMENU.LST are used to tell the
       door what files to display when the user selects options from those
       menus. You can now customize all the menu displays.

    7. The user can display help files. MAINMENU.HLP, INFOMENU.HLP,
       SRCHMENU.HLP, and CATMENU.HLP are provided. You can customize them
       if you wish.

    8. When the door starts up it displays a file named WELCOME. When it
       returns to the BBS it displays GOODBYE. You can customize these files.

    9. CD ROM drive replacement. In the text files where you put file and
       path names, you can use a '#' character to represent the CD ROM drive.
       In your SIGDOOR.CNF file you specify the actual drive letter that the
       door will use whenever it sees a path that starts with '#:'. That way
       you only have to change the drive letter in one place.


Release 1.5B
(never released)

    The word 'diskette' is now spelled correctly on the main menu.


Release 1.5A
06/06/90

    The "Yes/No" prompt to continue the keyword search is fixed.


Release 1.5
06/05/90

    1. The DODINDEX.DAT and LIBDEF files have been updated for the 8th
       edition (April 1990) of the PC SIG Library on CD ROM.

    2. Two bugs were fixed. The eof processing has been corrected, so
       the program no longer gets into a loop when scanning the Directory
       on Disk file. And when your PCBoard Page Size is set to 0, it no
       long prompts you to hit ENTER on every menu line.

    The changes are quite minor. If you are already using release 1.4,
    all you need do is overlay your SIGDOOR.EXE file with the new version.


Release 1.4
10/14/89

    1. The DODINDEX.DAT and LIBDEF files have been updated for the 7th
       edition (September 1989) of the PC SIG Library on CD ROM.

    2. The options that display files from the CD ROM (View Informaton
       and List Diskettes By Category) have been made more flexible.
       You now specify a file that has the menu items and the name of
       the file to display for each menu selection.

    3. The documentation and support files have been updated to use
       PKZIP as a default instead of PKPAK. The previous problem with
       PKZIP (where it set the read-only attribute on the files) has been
       resolved beginning with PKZIP 1.01.

    4. The file extension used by the archive/compression utility is now
       a parameter in the SIGDOOR.CNF file.

    5. The door checks to see if the diskette has already been prepared
       for downloading, and doesn't re-create the archive file when one
       already exists.

    6. A new option is added to list the diskettes that are already
       prepared and available for downloading.

    7. A number of cosmetic changes have been made.

    NOTE: Because of the changes, you will need to re-install from
    scratch. In particular, you MUST replace your SIGDOOR.CNF file, or
    the door will fail. You will probably also have to update the disk
    drive information in the new INFOMENU and CATMENU files.
