-  <h4>V0.9 (16-Aug-22)</h4>
+  <h4>V0.10 (undefined)</h4>
     <ul>
-    <li>Maintenance. Updated all dependencies to the latest versions.
-    <li>Bugfix: Fixed condition code for asr/lsr/lsl, which is has a different behaviour for V flag than asl.
-    <li>Bugfix: Fixed 'Unknown op size' exception when uppercase sizes were used.
-    <li>Bugfix: Refactoring was broken for newer IDE versions, at least for me, this now works again by unknown magic.
+    <li>New: Added semantic highlighting. Currently available for data and address registers and local labels.
     </ul>
