+ <h2>Changes in SRU from Versions 1.1 to 1.2</h2>
+ <p>SRU Version 1.2 is in development and will be released soon. This
+ page summarizes the differences from version 1.1. </p>
+ <h3>CQL Changes </h3>
+ <ol>
+ <li> CQL renamed the "contextual query language".</li>
+ <li>'scr' relation eliminated. '=' becomes (in effect) server choice. When
+ relation is omitted, '=' is assumed.</li>
+ <li> 'adj' relation defined for word adjacency.</li>
+ <li>'exact' relation eliminated. Replaced by '=='. </li>
+ <li>'regexp' relation modifier defined. </li>
+ <li>Sorting is added as a cql feature (the 'sortby' clause).</li>
+ <li>Proximity. Defaults are now server defined, not standard defined. Hence "prox" can
+ be anything the server wants to do proximately, not necessarily with
+ a default of adjacency.
+ <p>Proximity units (other than in cql set) are treated such that "unit" is
+ a value in a context set, rather than the unit value being a value
+ in a context set. Proximity units 'word', 'sentence', 'paragraph',
+ which are included in the cql set, are explicitly undefined.</p>
+ </li>
+ </ol>
+ <h3>Protocol Changes </h3>
+ <ol>
+ <li>Record identifier (optional) added to record structure.</li>
+ <li> XCQL parameter becomes optional.</li>
+ <li> XPath parameter dropped (will become an extension).</li>
+ <li> base url added to response.</li>
+ <li> record hits incorporated into xcql.</li>
+ <li> Z39.92 replaces explain.</li>
+ <li>Sorting is no longer a protocol function (see point 6 in CQL list). </li>
+ </ol>
