Laura and TomH are correct. We announced no future changes will be made to the HTML style websites in updates or versions. Changes will only be made to the RootsMagic 7 style My RootsMagic (Publish Online) websites.
There's a terminology problem here. There are really three kinds of websites that can be produced with RM, not just two.
The HTML websites go all the way back to RootsMagic version 1. Indeed, they go all the way back to Family Origins days. These are the kind of websites that are not going to be updated. They have also been described as being deprecated. Normally, that is the terminology that vendors use when a future release will not include a feature. But so far as I know, RM has not yet announced the actual end of of the feature - just that the feature will no longer be updated. Still, I would not be surprised if the next release of RM does not include the feature (or the next next release, etc.). The HTML websites do have the advantages that they can be loaded onto any Web hosting service that hosts HTML pages, and that they are searchable via Google and other search engines. But they cannot be loaded onto RM's own MyRootsMagic web site. There are no limits to how many such pages you can produce nor on how large they can be as long as you have a place to host them.
There are two kinds of "RootsMagic 7 style" websites (or maybe they should be called "RootsMagic 6 style" web sites). The older of the two is based on XML. Such pages can be loaded onto any Web hosting service that hosts HTML pages. But the pages are not searchable via Google and other search engines. And, I do not believe that such pages can be loaded onto RM's own MyRootsMagic web site. There are no limits to how many such pages you can produce nor on how large they can be as long as you have a place to host them.
The newer of the two actually loads your RM database onto the Web site and builds the pages that are displayed dynamically based on queries against the copy of your database that is loaded onto the Web site. The pages are searchable via Google and other search engines. They can be loaded onto RM's own MyRootsMagic web site, but I do not believe they can be loaded anywhere else. Because the MyRootsMagic web site is a free service provided by RM, such Web sites are limited as to number of sites and size of sites.
No one of the three solutions meets all needs. For example, if you want a web site that is unlimited in size, you cannot use the MyRootsMagic web site. That leaves you with the option of the XML pages which are not searchable with Google and with the HTML pages which have been deprecated. Plus, I very much prefer the look and feel of the HTML pages to the look and feel of either of the other options (I believe I'm very much in the minority in this preference, by they way). But in any case, I really hope that the HTML pages do not go away until there is an option that is searchable via Google and other search engines and that is not limited in size nor as to where it may be hosted.
