 <p class="body">What to Expect:</p>
 <p class="body">	•	Big improvements - This is our most exciting version to date, already a significant improvement in many ways over 2.49</p>
 <p class="body">	•	Missing/Incomplete Features - Although most of it is there, not all functionality from pre-2.5 versions has been restored yet. Some functionality may be re-implemented a different way.</p>
 <p class="body">	•	Changes - If you're used to the old Blenders, Blender 2.5 may seem quite different at first, but it won't be long before it grows on you even more than before.</p>
