This release contains several improvements to the core eg for search, as well as bugs fixes, eg when the post does not exist, then an error will occur on a particular Linux distribution.
So what's new in this version? only a few additional functions, thus allowing the use of dynamic headings, for example:
<?php if(is_index()) {?>
<h1 class="blog-title"><a rel="home" href="<?php echo site_url() ?>"><?php echo blog_title() ?></a></h1>
<?php } else {?>
<h2 class="blog-title"><a rel="home" href="<?php echo site_url() ?>"><?php echo blog_title() ?></a></h2>
<?php } ?>
With the use of such code then the name of the blog will only use H1 on the index page, eg frontpage, tag, archive, and search result pages.
Looks like this is enough for any HTMLy users who want to create their own themes.
