- RELEASE NOTES
- Global Chat (tm) Internet chat client from Prospero Systems Research, Inc.
- v1.1.2 for Microsoft Windows
-
- -----------------------------------------------------------------------------
-
- The enclosed executable is a version of Global Chat 1.1 for
- Microsoft Windows
-
- Version 1.1.2, built on November 16, 1995
- ------------------------------------------
- V1.1.2 adds the following to the September 23 build:
-
- * Wider space for entering server name in the Sign-In dialog
- * Hook for online help file (actual .HLP file not yet ready)
- * Fixes bug where it could not obtain graphic banners from certain configured
- Web servers.
-
-
- Version 1.1.1, built on September 23, 1995
- ------------------------------------------
-
- This is the first public release of version 1.1. If you had
- been using the September 13 prerelease, you should delete it from disk and
- replace it with the current version.
-
- V1.1.1 adds the following to the September 13 build:
-
- * Completed the implementation of, and fixed bugs with the / commands
-
- * Made the graphics caching more robust
-
- * Added "scroll freezing" to the main display window.
-
- * Fixed two bugs related to the list of member nicknames
-
- 1) Fleshed-out "/" commands
-
- We now have
-
- /leave
- /part
- To leave the current channel.
-
- Also, in all "/" commands that take a channel name, an asterisk (*) may be
- used in lieu of the channel name to indicate the current channel.
-
- 2) The graphics cache now uses a more robust random filename generator.
-
- 3) Scroll freezing.
-
- It's now possible to "freeze" the main display window, so you can scroll
- through old messages, without having the screen scroll to the bottom
- whenever a new message arrives. In order to freeze the scrolling, select
- "Freeze Scrolling" from the "Edit" menu (or use the accelerator, Ctrl-F).
- Any incoming messages will be held until you "unfreeze" the scrolling.
- After you turn freezing on, an "Unfreeze" button will appear in the middle
- of the screen. Click on this button to trun freezing off. When you turn
- freezing off, all saved messages will be displayed at the bottom of the
- window. The "scroll freeze" feature is designed to be used for brief
- periods of time only. In the event that the program would run out of
- memory if it were to continue to hold incoming message, the freezing will
- terminate and some portion of the held messages may be discarded.
-
- WARNING: freezing for a long period of time may cause the program to crash.
-
- 4) Fixed 2 outstanding memberlist bugs
-
- - Previously, in some cases when you had joined a channel with a very large
- number of users, most of the member names would not have appeared in the
- list. This has been fixed.
-
- - Previously, the memberlist would inadvertently delete members who had not
- left the chanel. This has been fixed.
-
-
- Build of September 13, 1995
- ----------------------------
-
- This is the first pre-release build of v1.1 and adds the following features
- to v1.0, released on August 1.
-
- * Ability to receive real-time graphics from the server.
-
- * Ability to display short real-time text messages "out-of-band" from the
- main chat discussion
-
- * Ability to send externally generated URLs to certain Web browsers without
- user intervention. i.e. a group leader can take audience members on a
- "guided tour" of the Web, by sending URLs to a channel, and all members of
- the audience will go to those Web pages.
-
- * Implemented several more of the traditional IRC "slash" commands
-
- * Implemented web-based authentication capability, which enables secure
- members-only access to a Global Stage Theater or Stadium server.
-
- * Fixed a bug regarding related to improper characters in nick names
-
- * Replaced the prior embedded cycling graphics with a new set.
-
- 1. Real-time graphics
-
- This version of the client will receive and display graphic banners
- distributed from the Global Stage "Stadium" server v1.1 or later. The
- client *must* be connected to a Global Stage Stadium or compatible server
- for the graphics to display. Apart from that, no end user intervention is
- required. For information on sending graphics through the server, please
- refer to the note below on the multimedia "slash" commands, and also to the
- separate addendum to the server documentation, which is available to Global
- Stage server customers separately.
-
- 1a. Graphics cache
-
- To support the graphics, the Global Chat client maintains a cache of the
- most recently used graphic images. These graphics are stored in the Global
- Chat runtime directory in files called gcdbNNNN.gif, (where NNNN is 4 or
- fewer decimal digits). The index file for the cache is in the runtime
- directory in file gc-cache.txt. Any graphic which is found in cache will
- be displayed instantly upon command from the server. Any graphic not in
- cache will be delivered over the network and stored in cache for future
- use.
-
- 1b. Banner URLs
-
- As with the embedded graphics, a real-time banner can be associated with a
- WWW URL, which is displayed underneath the graphic. When the user
- double-clicks on the URL, GlobalChat will send a message to the user's Web
- browser (Netscape 1.1 and later and Enhanced Mosaic 2.0 and later) to force
- a download of the URLs document.
-
- 2. Real-time "out-of-band" text messages
-
- The region of the screen that normally displays the banner URL may also be
- used to receive short text messages sent from the server. This text region
- will display both the banner's URL as well as the text message. The user
- can toggle between the two types of text messages by right-clicking the
- mouse on the text region. To see how to send such text messages through
- the server, please see the note on multimedia "slash" commands, below. The
- client *must* be connected to a GlobalStage Stadium v1.1 or compatible
- server for any text messages to appear.
-
- 3. Guided web tours -- server will automatically cause user's Web browser
- to change Web pages.
-
- Users who have an externally controllable browser (Netscape 1.1 or later,
- Enhanced Mosaic 2.0 or later) will be able to enjoy sessions where a group
- leader sends URLs into a chat session which cause the user's browser to
- automatically visit the page without any end-user intervention. This
- capability is available from a Global Stage Stadium or compatible server.
- Information on commands that enable the user to send URLs to a chat session
- is found in the section below on mulitmedia "slash" commands.
-
- 4. IRC "Slash" Commands
-
- Global Chat 1.1 offers several additional IRC "slash" commands which offers
- an interface that is similar to older freeware IRC clients. In addition,
- we also offer some new multimedia slash commands that enable the user to
- send graphic banners and URLs through a Global Stage Stadium server.
-
- 4a. Newly implemented traditional IRC commands:
- In addition to /mode and /topic , which were implemented in v1.0, we now offer:
-
- /join <channel> [<password>]
-
- To join a channel, with optional password
-
- Examples: /join #foo
- /join #bar mypassword
-
- /msg <recipient> <message>
-
- Send a message to <recipient> which may either be a user, a channel
- or a comma-separated list of users
-
- Examples: /msg fred how's it going, big guy?
- /msg fred,edna hey, haven't seen you love birds in a while
-
- /me <action>
-
- Send an "action" to the current channel. i.e. if a user with the
- nick name "fred" types the command:
-
- /me is having fun,
-
- Other users in the channel will see the message:
- ACTION fred is having fun
-
- /quit
- Disconnects the user from the server
-
- 4b. Multimedia commands
-
- We also support the following new commands to enable users to send graphic
- banners and URLs to the channel as described above. The following commands
- will work only if the user is connected to a Global Stage Stadium or
- compatible server. Due to the potential for nuisance, the server restricts
- the ability to send multimedia commands. At present a user must be a
- server supervisor or channel operator to send multimedia commands to a
- channel, and must be a server supervisor to send multimedia to individual
- users.
-
- /url <recipient> <url>
-
- Sends the url to the recipient, which may either be a channel an
- individual, or a comma-separated list of individuals. If the recipient is
- then running a suitable externally-controllable Web browser, the receiving
- Global Chat will automatically send the URL to the Web browser for
- immediate download.
-
- Example: /url fred http://www.ibm.com/
-
- /banner <recipient> <graphic-url> [COURL=<co-url>]
-
- This sends a graphic banner to the recipient, which may either be a
- channel an individual, or a comma-separated list of individuals.
- <graphic-url> is a URL for a graphic banner, which is currently limited to
- a GIF image, of not more than 80 pixels high and not more than 500 pixels
- wide. The graphic file must be obtainable using simple HTTP from the Web
- server specified in <graphic-url>. (HTTP authentication and redirection is
- not currently implemented) When the recipients receive the banner command,
- they will either retrieve the graphic from the network, or from the cache,
- if present., and display the graphic in the banner region.
-
- Optionally, the banner can be linked with a "co-URL" which will be
- displayed in the text region underneath the graphic banner, and will be
- sent to the Web browser when the user clicks on the banner.
-
- Examples:
- /banner fred http://prospero.com/ibm.gif COURL=http://www.ibm.com/
- /banner fred,edna http://prospero.com/mci.gif
-
- The directory http://he.net/~prospero/banners/ contains a set of
- suitable graphics for testing and experimentation only.
-
- /text <recipient> <text message>
-
- Sends a "banner text" message to the recipient, which may either be
- a channel an individual, or a comma-separated list of channels and
- individuals. The text message will be displayed on the same region where
- the banner url is displayed.
-
- 5. Web based authentication
-
- It is now possible to use Global Stage Theater and Stadium and Global Chat
- v1.1 to create an exclusive chat session, where users must authenticate
- themselves through a Web page. A demonstration page for this capability
- currently exists at http://prospero.com/password/ In the current demo you
- may use any nickname and personal names to enter the server from the Web
- page. If you attempt to enter the server directly (signing in to host
- prospero.com, port 6667) and not from the web page you will be denied
- access.
-
- We will soon make available to Global Stage Theater and Stadium customers
- the skeleton perl scripts that may be extended to integrate with any Web
- authentication scheme.
-
- 6. Fixed bug regarding improper characters in nick name
-
- The previous versions of Global Chat for Windows allowed users to enter
- nicknames containing illegal characters, such as SPACE or COMMA. In some
- situations, the illegal nickname could cause problems with servers and make
- it difficult or impossible for the user to send or receive messages.
-
- Global Chat 1.1 checks for valid nicknames, and prompts the user with a
- dialog box if an improper nickname is entered.
-
- 7. New set of embedded graphics
-
- We replaced the previous set of embedded rotating banners with a new set.
- Our current advertsing partners are: c|net, Delphi/MCI, Mecklermedia and
- GeoNet.
