           GIMP 2.10.4 includes a lot of bug fixes as well as various
-          optimizations. In particular fonts loading is not blocking
-          startup anymore. Instead any feature using fonts (such as the
-          Text tool) will now be blocked until fonts are fully loaded.
-          This change was highly requested on some platforms where font
-          loading was sometimes painfully slow.

-          The Measurement tool is augmented with a new feature, "Auto
-          straighten", allowing to rotate the active drawable (layer,
-          channel…) with the measurement line used as horizon.
-          As other transform tools, the feature will work on linked
-          drawables as well.
+          optimizations. Most notable changes are:

+        <ul>
+          <_li>
+          Straightening in Measurement tool: layers can be rotated using
+          the measurement line as horizon
+          </_li>
+          <_li>
+          Fast startup: fonts loading is not blocking startup anymore

+          <_li>
+          Fonts Tagging with the same user interface as for brushes,
+          patterns, and gradients
+          </_li>
+          <_li>
+          PSD support: a pre-composited version of a PSD image can be
+          imported
+          </_li>
+          <_li>
+          Dashboard update: new "Memory" group and improved "Swap"
