Possible compatibility problems with earlier versions marked with '*'.
+* Added prefix "yaz_" for the functions log_init.., log_file.. and
+log_mask_str. This was done to avoid name conflicts with other
+libraries (say other PHP extensions).
+
+Added raw OID member for preferred record syntax (request_format_raw)
+and returned record syntax (output_format_raw) for backend fetch method.
+
Config file yaz-config now accepts options so that it returns specific
compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
