+Changes with nginx 0.3.48                                        29 May 2006
+
+    *) Change: now the ngx_http_charset_module works for subrequests, if 
+       the response has no "Content-Type" header line.
+
+    *) Bugfix: if the "proxy_pass" directive has no URI part, then the 
+       "proxy_redirect default" directive add the unnecessary slash in 
+       start of the rewritten redirect.
+
+    *) Bugfix: the internal redirect always transform client's HTTP method 
+       to GET, now the transformation is made for the "X-Accel-Redirect" 
+       redirects only and if the method is not HEAD; bug appeared in 0.3.42.
+
+    *) Bugfix: the ngx_http_perl_module could not be built, if the perl was 
+       built with the threads support; bug appeared in 0.3.46.
+
+
 Changes with nginx 0.3.47                                        23 May 2006
 
     *) Feature: the "upstream" directive.

+Изменения в nginx 0.3.48                                          29.05.2006
+
+    *) Изменение: теперь модуль ngx_http_charset_module работает для 
+       подзапросов, в ответах которых нет строки заголовка "Content-Type".
+
+    *) Исправление: если в директиве proxy_pass не было URI, то директива 
+       "proxy_redirect default" добавляла в переписанный редирект в начало 
+       лишний слэш.
+
+    *) Исправление: внутренний редирект всегда превращал любой HTTP-метод в 
+       GET, теперь это делается только для редиректов, выполняемых с 
+       помощью X-Accel-Redirect, и у которых метод не равен HEAD; ошибка 
+       появилась в 0.3.42.
+
+    *) Исправление: модуль ngx_http_perl_module не собирался, если перл был 
+       с поддержкой потоков; ошибка появилась в 0.3.46.
+
+
 Изменения в nginx 0.3.47                                          23.05.2006
 
     *) Добавление: директива upstream.
