       bug appeared in 0.1.29.

    *) Bugfix: 3, 4, 7, and 8 the "proxy_set_header" directives in one
       level cause the bus fault on start up.

+
+    *) Исправление: nginx не собирался с параметром --without-pcre; ошибка 
+       появилась в 0.1.29.
+
+    *) Исправление: 3, 5, 7 и 8 директив proxy_set_header на одном уровне 
+       вызывали bus fault при запуске.
+
+    *) Исправление: в редиректах внутри HTTPS сервера был указан протокол 
+       HTTP.
+
+    *) Исправление: если директива rewrite использовала выделения внутри 
+       директивы if, то возвращалась ошибка 500.
