+IMPORTANT FIXES FOR 1.12.6
+--------------------------
+
+- [#307](https://github.com/zendframework/zf1/pull/307) fixes a backwards
+  compatibility break in the `Zend_Locale` component. 1.12.4 updated the
+  [CLDR](http://cldr.unicode.org) version used by Zend Framework 1, which
+  resulted in the removal of several locales we previously supported. The patch
+  in #307 adds locale aliases for these to the new locales supported in recent
+  versions of the CLDR, ensuring backwards compatibility for ZF1 users.
