nginx 0.8.34

    *) Bugfix: nginx did not support all ciphers and digests used in client
       certificates.
       Thanks to Innocenty Enikeew.

    *) Bugfix: nginx cached incorrectly FastCGI responses if there was
       large stderr output before response.

    *) Bugfix: nginx did not support HTTPS referrers.

    *) Bugfix: nginx/Windows might not find file if path in configuration
       was given in other character case; the bug had appeared in 0.8.34.

    *) Bugfix: the $date_local variable has an incorrect value, if the "%s"
       format was used.
       Thanks to Maxim Dounin.

    *) Bugfix: if ssl_session_cache was not set or was set to "none", then
       during client certificate verify the error "session id context
       uninitialized" might occur; the bug had appeared in 0.7.1.

    *) Bugfix: a geo range returned default value if the range included two
       or more /16 networks and did not begin at /16 network boundary.

    *) Bugfix: a block used in a "stub" parameter of an "include" SSI
       directive was output with "text/plain" MIME type.

    *) Bugfix: $r->sleep() did not work; the bug had appeared in 0.8.11.

+Изменения в nginx 0.8.34                                          03.03.2010
+
+    *) Исправление: nginx не поддерживал все шифры, используемые в 
+       клиентских сертификатах.
+       Спасибо Иннокентию Еникееву.
+
+    *) Исправление: nginx неправильно кэшировал FastCGI-ответы, если перед 
+       ответом было много вывода в stderr.
+
+    *) Исправление: nginx не поддерживал HTTPS-рефереры.
+
+    *) Исправление: nginx/Windows мог не находить файлы, если путь в 
+       конфигурации был задан в другом регистре; ошибка появилась в 0.8.34.
+
+    *) Исправление: переменная $date_local выдавала неверное время, если 
+       использовался формат "%s".
+       Спасибо Максиму Дунину.
+
+    *) Исправление: если ssl_session_cache не был установлен или установлен 
+       в none, то при проверке клиентского сертификаты могла происходить 
+       ошибка "session id context uninitialized"; ошибка появилась в 0.7.1.
+
+    *) Исправление: geo-диапазон возвращал значение по умолчанию, если 
+       диапазон включал в себя одну и более сетей размером /16 и не 
+       начинался на границе сети размером /16.
+
+    *) Исправление: блок, используемый в параметре stub в SSI-директиве 
+       include, выводился с MIME-типом "text/plain".
