+
+### В релиз вошли следующие исправления ошибок
+
+- Исправлена работа метода `concat()` в i-bem-dom__collection ([#1488](https://github.com/bem/bem-core/issues/1488)).
+- Исправлена опечатка в `ua__dom`, приводящая к runtime-ошибке при использовании touch-уровня ([#1479](https://github.com/bem/bem-core/issues/1478)).
+- dist: Исправлена ошибка, при которой `i-bem-dom__init_auto` подключался в `no-autoinit`-бандл ([#1482](https://github.com/bem/bem-core/issues/1481)).
