With most of the work focused on the backend for WP 2.6, I’m kind of glad that there’s not much changes in the code on the theme side. In fact you can safely ignore the new codes and use your existing theme without any modifications. The changes are as below.
Note: WP 2.6 RC2 vs WP 2.5.1
1) comments.php - indicates whether the Name and Mail fields are required, mainly for browsers that support ARIA-Accessibility Rich Internet Applications
line 81:
<p><input type="text" name="author" id="author" value="<?php echo $comment_author; ?>" size="22" tabindex="1" <?php if ($req) echo "aria-required='true'"; ?> />line 84:
<p><input type="text" name="email" id="email" value="<?php echo $comment_author_email; ?>" size="22" tabindex="2" <?php if ($req) echo "aria-required='true'"; ?> />
2) style.css - a new css class “.hidden”, which is used only once in searchform.php (see item 3 below)
line 619:
.hidden {
display: none;
}
3) searchform.php - hidden for future use?
line 2:
<label class="hidden" for="s"><?php _e('Search for:'); ?></label>
