<ul>
<li>New, incompatible data format of the binary collation data in
coll/*.res and coll/ucadata.icu data files.
coll/invuca.icu has been removed.</li>
<li>Data loading will not fall back to building from rules any more

(This removes the dependency from the "runtime" code on the builder.)</li>
<li>Rule syntax and semantics tightened and improved, matching
