# Introduction

This version of the OpCon Configuration Tool adds one new feature and
makes one usability change. All are described below.

The previous release of this software was version 2.1.

# Bug Fixes

-   None.

# New Feature

The following feature is new to the OpCon Configuration Tool
version 3.0.

-   When it came to database and network domain connections, OpCon
    version 2.1 was controlled by the information in its OpCon.ini file.
    Only one connection (database and network domain) could be
    specified. In fact, the OpCon Configuration Tool was created to make
    the job of changing the connection parameters easier.

> The new OpCon version 3.0 can display a list of connections when the
> program is run. This allows the user to pick the connection he or she
> wants to use for during the OpCon session.
>
> This new version of the OpCon Configuration Tool supports this
> capability, by enabling the easy creation, modification, and deletion
> of one or more connections.
>
> Most installations of OpCon, however, will not require this
> capability. In those cases OpCon and the Configuration Tool will
> behave just like they did before -- using a single connection and not
> allowing the user to select a connection (this is the default
> setting).
>
> With a small change to the OpCon.ini file, the multiple connection
> capability in OpCon *and* in the OpCon Configuration Tool can be
> activated.
>
> The following figures show the old (version 2.1) and new (version 3.0)
> Configuration Tools. The version 3.0 tool is in non-multiple
> connection (default) mode. They look (and behave) almost exactly
> alike:

> The trick to activating (and de-activating) multi-connect mode is in
> the OpCon.ini file. First, exit from OpCon and from the OpCon
> Configuration Tool. OpCon the OpCon.ini file into a plain text editor
> (Notepad will work fine).

> To turn on multi-connect capability, change the zero to a one:

> MultiConnect=1

> Save the file. If you want to turn multi-connect mode off, replace the
> one with a zero. Note that if you define more than one connection and
> then turn multi-connect mode off, the first connection (the one at the
> top of the connections list) will be used.

# Usability Change

-   The database password field was changed so that the passwords now
    appear as a series of asterisks. The passwords are now hidden from
    casual view.
