+- Mozilla Thunderbird 45.5.0 (boo#1009026)
+- Changed behavior:
+  * Changed recipient address entry: Arrow-keys now copy the pop-up
+    value to the input field. Mouse-hovered pop-up value can no
+    longer be confirmed with tab or enter key. This restores the
+    behavior of Thunderbird 24.
+  * Support changes to character limit in Twitter
+- Bugs fixed:
+  * Reply with selected text containing quote resulted in wrong
+    quoting level indication
+  * Email invitation might not be displayed when description
+    contains non-ASCII characters
+  * Attempting to sort messages on the Date field whilst a quick
+    filter is applied got stuck on sort descending
+  * Mail address display at header pane displayed incorrectly if
+    the address contains UTF-8 according to RFC 6532
