 ChangeLog for RQL
 =================
 
+	--
+   * fix solutions computation crash with some query using sub-queries (closes #37423)
+
 2010-07-28  --  0.26.4
     * fix re-annotation pb: some stinfo keys were not properly reinitialized
       which may cause pb later (at sql generation time for instance)
