Changes with nginx 0.3.31 10 Mar 2006v0.3.31

    *) Change: now nginx passes the malformed proxied backend responses.

    *) Feature: the "listen" directives support the address in the "*:port"
       form.

    *) Feature: the EVFILER_TIMER support in MacOSX 10.4.

    *) Workaround: for MacOSX 64-bit kernel kqueue millisecond timeout bug.
       Thanks Andrei Nigmatulin.

    *) Bugfix: if there were several "listen" directives listening one
       various addresses inside one server, then server names like
       "*.domain.tld" worked for first address only; bug appeared in 0.3.18.

    *) Bugfix: if the HTTP protocol was used in the "proxy_pass" directive
       and the request body was in temporarily file then the request was
       not transferred.

    *) Bugfix: perl 5.8.8 compatibility.

+
+    *) Изменение: теперь nginx передаёт неверные ответы проксированного

+
+    *) Добавление: директивы listen поддерживают адрес в виде "*:порт".
+
+    *) Добавление: поддержка EVFILER_TIMER в MacOSX 10.4.
+
+    *) Изменение: обход ошибки обработки миллисекундных таймаутов kqueue в 
+       64-битном ядре MacOSX. Спасибо Андрею Нигматулину.
+
+    *) Исправление: если внутри одного сервера описаны несколько директив 
+       listen, слушающих на разных адресах, то имена серверов вида 
+       "*.domain.tld" работали только для первого адреса; ошибка появилась 
+       в 0.3.18.
+
+    *) Исправление: при использовании протокола HTTPS в директиве 
+       proxy_pass не передавались запросы с телом, записанным во временный 
+       файл.
+
+    *) Исправление: совместимость с perl 5.8.8.
