+### <i class="icon icon-common" data-icon="🆕"></i>	 What's new in v1.3
+
+This version brings the most user-facing changes in several years as we've added in far more "common" icons and simplified the font stack.
+
+The new EBI-Common font:
+- Is a set of generic utility icons
+- Merges the former EBI-Social, EBI-Generic, EBI-Functional
+- Key mapping for the old EBI-Social and EBI-Generic have changed (see mappings below)
+- EBI-Functional key mappings have not changed
+- Adds non-redundant icons from Font Awesome (not yet implemented in dev version)
+
+For more background on the change, <a href="https://github.com/ebiwd/EBI-Icon-fonts/issues/22" class="readmore">see the notes</a>
+
+There have also been a number of "under the hood" changes in v1.3. If you're a developer you can [read about those changes here](https://github.com/ebiwd/EBI-Icon-fonts/issues/21).
