several questions covering SB, DA , cc2018

Usinghing dwn cc2018 on Mac currently hav betav2 installed . noticed SB has also been upgraded also, is this part of the live updates from beta
what are the correct steps to ensure a trouble free upgrade .

any idea when the MRT tutorial be upgraded

Been ill for several weeks, so I was wondering if there had been discount for beta participants.
CMS -
Any likely cool this will be changed to Mysqli
the possibility of using same database across multiple domains
adding PHPCode / variable support

The MRT steps should be the same for the new version. Some users have reported issues with multiple insert and MRT, so I'm actually looking into those now and making bug fixes if necessary.

Unfortunately I couldn't offer additional discounts for BETA participants. The discounts are already pretty steep and I'm trying to fund the update of Design Extender and power CMS to MySQLi. Hopefully that will be next after all of the kinks are ironed out in DataBridge.

You can already use the same database across multiple sites if you set up your database to allow remote connections. I'm not sure what you mean by variable support... If you expand on what you are referring to I can comment on it more.

UPGRADE STEPS TO BE UNDERTAKEN ,TO MINIMISE POTENTIAL PROBLEMS

DELETE ALL EXISTING EXTENSIONS
DELETE CACHE
START DW
ADD DB/ DE/ SB /FT

POWER CMS
CAN U USE 1 DATABASE ACROSS MULTIPLE SITES, NOW, FUTURE OR NEVER
ADD PHP CODING SUPPORT IE <?php include (file)?> NOW, FUTURE OR NEVER

PS
WHAT CHANGES HAVE BEEN MADE WITH THE LATEST VERSION OF SB
HOW DO U SETUP DATABASE FOR REMOTE ACCESS

You should be able to use 1 database for multiple sites already. There is a database setting to allow remote connections and just use the same database server in your connection.

We probably won't allow direct php coding in the cms..there are just too many ways that could break things.

The largest changes are mySQLi support and improved email functionality.
Database remote access is a setting in the database itself. Talk to your hosting provider and they will be able to tell you if they support it and how to set it up.

to ensure smooth trouble free extension update, what steps to I need to follow

I think you should just install DataBridge V2... just make sure you have already uninstalled the Deprecated Server Behaviors, MySQLi Server Behaviors, and Data Bridge V1 if you have had them installed previously.
