+Add support for extra request / response data for SRU codecs and GFS.
+The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
+for extra data response buffer and length. For the GFS, both request
+and response data (XML) is carried in extra_args and extra_response_data
+for the search handler. Patch by Ko van der Sloot.
+
+--- 3.0.49 2009/10/01
+
+Make a number of functions defined in xmlquery.c static. These have
+never been declared in a public header file (yaz/xmlquery.h) and was
+made public by mistake.
+
+Improve speed of character conversions (iconv utilities). This makes
+conversions from MARC-8 faster.
+
+ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
+unless type desired is "raw". This will prevent type "xml" from
+returning ISO2709 .. Which obviously can not be XML parsed.
+
+Fix memory leak in ZOOM that would occur if option apdulog was used
+on a re-used connection.
+
+Frontend server logs HTTP requests.
+
+Frontend server now sends Z39.50 close when it times out (sesssion has
+been idle for too long). Versions 2.0.30 and earlier also sent close.
+But due to a mistake this was disabled in all versions after that, i.e.
+the server would just close the socket immediately.
