-      or none) thanks to the CommitLog, but until 1.1 they were not *isolated*

+    - Concurrent schema updates are now supported, with any conflicts
+      automatically resolved.  This makes temporary columnfamilies and
+      other uses of dynamic schema appropriate to use in applications.
+    - The CQL language has undergone a major revision, CQL3, the
+      highlights of which are covered at [1].  CQL3 is not
+      backwards-compatibile with CQL2, so we've introduced a
+      set_cql_version Thrift method to specify which version you want.
+      (The default remains CQL2 at least until Cassandra 1.2.)  cqlsh
+      adds a --cql3 flag to enable this.
