Changes with nginx 0.5.11 05 Feb 2007v0.5.11

    *) Feature: now configure detects system PCRE library in MacPorts.
       Thanks to Chris McGrath.

    *) Bugfix: the response was incorrect if several ranges were requested;
       bug appeared in 0.5.6.

    *) Bugfix: the "create_full_put_path" directive could not create the
       intermediate directories if no "dav_access" directive was set.
       Thanks to Evan Miller.

    *) Bugfix: the "0" response code might be logged in the access_log
       instead of the "400" and "408" error codes.

    *) Bugfix: a segmentation fault might occur in worker process if nginx
       was built with -O2 optimization.

+Изменения в nginx 0.5.11                                          05.02.2007
+
+    *) Добавление: теперь configure определяет библиотеку PCRE в 
+       MacPorts.
+       Спасибо Chris McGrath.
+
+    *) Исправление: ответ был неверным, если запрашивалось несколько 
+       диапазонов; ошибка появилась в 0.5.6.
+
+    *) Исправление: директива create_full_put_path не могла создавать 
+       промежуточные каталоги, если не была установлена директива 
+       dav_access.
+       Спасибо Evan Miller.
+
+    *) Исправление: вместо кодов ошибок "400" и "408" в access_log мог 
+       записываться код "0".
+
+    *) Исправление: при сборке с оптимизацией -O2 в рабочем процессе мог 
+       произойти segmentation fault.
