nginx 0.3.52

    *) Change: the ngx_http_index_module behavior for the "POST /" requests
       is reverted to the 0.3.40 version state: the module now does not
       return the 405 error.

    *) Bugfix: the worker process may got caught in an endless loop if the
       limit rate was used; bug appeared in 0.3.37.

    *) Bugfix: ngx_http_charset_module logged "unknown charset" alert, even
       if the recoding was not needed; bug appeared in 0.3.50.

    *) Bugfix: if a code response of the PUT request was 409, then a
       temporary file was not removed.

+Изменения в nginx 0.3.52                                          03.07.2006
+
+    *) Изменение: восстановлено поведение модуля ngx_http_index_module для 
+       запросов "POST /": как в версии до 0.3.40, модуль теперь не выдаёт 
+       ошибку 405.
+
+    *) Исправление: при использовании ограничения скорости рабочий процесс 
+       мог зациклиться; ошибка появилась в 0.3.37.
+
+    *) Исправление: модуль ngx_http_charset_module записывал в лог ошибку 
+       "unknown charset", даже если перекодировка не требовалась; ошибка 
+       появилась в 0.3.50.
+
+    *) Исправление: если в результате запроса PUT возвращался код 409, то 
+       временный файл не удалялся.

     *) Исправление: при некоторых условиях в SSI мог пропадать символы "<";
