+Изменения в nginx 0.8.32                                          11.01.2010
+
+    *) Исправление: ошибки при использовании кодировки UTF-8 в 
+       ngx_http_autoindex_module.
+       Спасибо Максиму Дунину.
+
+    *) Исправление: именованные выделения в регулярных выражениях работали 
+       только для двух переменных.
+       Спасибо Максиму Дунину.
+
+    *) Исправление: теперь в строке заголовка запроса "Host" используется 
+       имя "localhost", если в директиве auth_http указан unix domain 
+       сокет.
+       Спасибо Максиму Дунину.
+
+    *) Исправление: nginx не поддерживал передачу chunk'ами для 201-ых 
+       ответов.
+       Спасибо Julian Reich.
+
+    *) Исправление: если директива "expires modified" выставляла дату в 
+       прошлом, то в строке заголовка ответа "Cache-Control" выдавалось 
+       отрицательное число.
+       Спасибо Алексею Капранову.
