Upgrade Notes for Internet Gate 1.40
====================================

This version of Internet Gate has a new caching algorithm, more efficient
than the previous one, that makes the old cache files incompatible. If you
are upgrading from a version prior to 1.35, be sure to delete the old cache
files before running this version of Internet Gate.

The files you must delete are the following:

cache.dat
cache.idx

all located in the directory where Internet Gate was installed.


Using the dialer under OS/2
===========================

We have received reports about the dialer not being working properly under
OS/2. Since in all our test machines the dialer works fine we have decided
to include our PPP.EXE, SLIP.EXE and SLATTACH.EXE files in the distribution
package. These files will be installed in the same directory where Internet
Gate will be installed, and will be used by Internet Gate instead of the
one you have installed with the operating system.

THE INSTALLATION PROGRAM DOESN'T ALTER YOUR SYSTEM FILES, NOR THESE FILES
ARE INTENDED TO BE AN UPDATE TO THE FILES DISTRIBUTED BY IBM ITSELF.
COPYING THESE FILES OVER THE EXISTINGS MAY PRODUCE UNPREDICTABLE RESULTS
AND IS AT YOUR OWN RISK ONLY.

This is merely an attempt to work around some reported problems, if the
dialer still doesn't work, please contact us at support@maccasoft.com.


Changes made in version 1.41
============================

 * Fixed a bug in the DNS server that prevented access to some internet
   sites. Specifically, this fix has solve some problems with the ICQ
   usage.

 * Added support for the Ident protocol. A new page was added in the
   Preferences dialog to configure and enable the Ident server used
   by most IRC servers to validate the login. Since Igate doesn't allow
   user-logins, the Ident server can specify only a single user name for
   all connections.

 * Added support for IMAP4 proxy.

 * Added support for the ftp proxy authentication used by GetRight. This
   usefuly utility uses the sequence 

   ftp://<username>:<password>@@domain/directory/file.zip

   to authenticate the user to the remote ftp server, Igate can now detect
   and use this sequence.

 * Fixed the duplication of web pages when retrived from the cache.

 * The cache size limit is now working correctly.

 * OS/2 Version: fixed the non-proxy request radio button not working
   properly.


Changes made in version 1.40
============================

 * New user interface. Internet Gate has a new user interface more
   attractive and intuitive than the previous, with large toolbar buttons
   and menu bar.

 * The help file was almost completely rewritten to be more clear on some
   clumsy configuration points. Hopfully this new help file makes the
   installation and configuration of Internet Gate more easy. Added a
   troubleshooting section.

 * Added support for the 'Pragma: no-cache' parameter that tells the proxy
   to ignore the cached files and reload the resource from the remote
   server. Now when you hit the 'Reload' button on your web browser the
   page is effectively reloaded from the remote server and the proxy cache
   is updated.

 * The SOCKS server now fully supports SOCKS5, including UDP-ASSOCIATE
   requests. Now programs like ICQ can work with Internet Gate.

 * Added support for non-proxy requests to the HTTP and POP3 servers. When
   a non-proxy request is made to these servers, the connection will be
   routed to a configurable local server for handling. With this addition
   you can have Internet Gate working with your intranet's WEB and MAIL
   servers on the same machine.

 * Increased the buffer size for HTTP requests. This should avoid program
   crashes with extremely long url requests.

 * Added support for the ftp: protocol to the HTTP proxy server. Now you
   can do ftp transfers from your web browser without need to configure the
   SOCKS server.

 * Added support for UDP Mapped Links.
