Wordpress Themes - WP Forum at BFA - Image container change between versions 3.7.15 and 3.7.23

I upgraded from ATA 3.7.15 to 3.7.23 on one of my sites and the site header went all wonky. (I have an amount of css going on in there)

I see that the html coding has changed between those versions. Here's a simplified view source grab from the same site using the two versions....

Code:

ATA 3.7.15



<div id="imagecontainer" class="header-image-container" style="background: url() top center no-repeat;">

  <div class="codeoverlay"></div>

  <div class="titleoverlay"><h2 class="blogtitle"><a href="">Blog-title</h2></div>

</div>



ATA 3.7.23



<div id="imagecontainer-pre" class="header-image-container-pre">

  <div id="imagecontainer" class="header-image-container" style="background: url() top center no-repeat;"></div>

  <div class="codeoverlay"></div>

  <div class="titleoverlay"><h2 class="blogtitle"><a href="">Blog-title</a></h2></div>

</div>

You can see that there's a new div (imagecontainer-pre) wrapping around everything and that the "codeoverlay" and "titleoverlay" divs are no longer contained inside of the "imagecontainer" div.

Is this a permanent change and this is the way it will be ongoing?

I don't want to make css changes to compensate for the new coding, only to find that in the next update that things change again...

Inquiring minds and all of that...

Thanks!
