zMUD has gone through a lot of changes between version 4.x, 5.x, 61x and 7.0x. Some of these changes might make upgrading to v7.0x a bit more difficult than expected. Of course, if you have kept up with all of the beta versions, 7.0x will seem warm and friendly. But taking the leap from 5.55 directly to 7.0x might be somewhat of a shock and require relearning some of zMUD features. Migrating from v6.62 to v7.0 should be much easier. However, be assured that 7.0x is big of improvement over older versions. Both new users and advanced users will find many important features in 7.0x that make MUDding even better. Also, most all of the known bugs in previous versions were fixed.
I'm assuming that you are using zMUD for MUDding because it has the best user interface and the most power and speed compared to any other MUD client available. Well, comparing v7.0x to older versions:
When upgrading to version v7.0x, you will be required to re-enter your registration code. So, you will initially see the Trial screen for v7.0x. Don't panic! You do NOT need to buy a new registration code. Simply click the License button, enter your registration code into the Order ID field, then click Install License. If you have lost or forgotten your registration code, simply go into your eLicense Control Panel, double-click the Zugg Software icon, then right-click on the first zMUD icon and select License Receipt.
This new version of zMUD makes extensive use of the Microsoft Data Access Components (MDAC) that are part of Windows. MDAC is shipped with all versions of Windows since Windows 98, but there have been a large number of versions of MDAC, some of which are slow or incompatible with zMUD. If you have Windows 2000 or Windows XP, then you shouldn't have any problems. If you have Windows NT or Windows 98, it will depend upon how up-to-date you have kept your system with service packs and what other software, like Microsoft Office, you might have installed. If you have Windows 95, you will probably have to install the MDAC system software before you can use the new version of zMUD. zMUD should prompt you if it detects problems with your MDAC/ADO software. It will direct you to the http://www.zuggsoft.com/data page for help with installing.
For most systems, the best way to get a reliable MDAC system seems to be installing MDAC 2.8 first, followed by installing the Jet 4.0 OLEDB files.
If the new mapper is really slow (for example, if it takes more than 30 seconds to load your map or a zone), then you probably have the old MDAC software. Try the above procedure to update MDAC to see if that helps. Also, if you have used any BETA versions of zMUD between 6.30 and 6.68, then you should make sure to re-convert your maps using the new zsConvert program that comes with zMUD to make sure you have the fasted and most stable maps.
Here is a step-by-step procedure for upgrading to v7.0x
Of course, since there have been so many versions of zMUD, not all upgrades might go smoothly. The most common problem is corrupted *.MUD settings files (contains your aliases, triggers, etc) or corrupted *.MAP files from the old automapper.
If zMUD hangs or crashes when you try to connect to one of your characters, your *.MUD settings file for that character might be corrupted. It is actually easy for files to get corrupted. Saving your settings after getting an Access Violation error is the most common way for this to happen. v7.0x has been improved and there is less of a chance of corrupting your files if you use the new version. Some older versions corrupted files very easily. However, not all is lost.
v7.0xx should automatically convert your old *.ZZZ and *.MAP files into the new *.MDB database format. If it fails to do this, then you might have the incorrect MDAC/ADO system software on your system. Go to http://www.zuggsoft.com/data for more information on upgrading this system software.
There were several bugs in the script and trigger parsers in older versions of zMUD that were fixed in v7.0x. If you were using some of these bugs, then some of your scripts may no longer work. You might have to tweak some of your aliases or triggers. Refer to the online help guide or the zMUD Programming Manual on the web. You can also post scripting questions to the Discussion Forum where several zMUD Gurus are prepared to help you.
It has been a long time between the 6.62 and 7.0x releases and I hope you like what you see. Most of the improvements are suggested by zMUD users themselves. If you have ideas for improvements, feel free to send them to me at firstname.lastname@example.org. Of course, if you find bugs you can report them to me also. Keep an eye on the Beta Forum for the latest breaking zMUD version news.
