   172 * Lifting:
       
   173   - parametrized correspondence relations are now supported:
       
   174     + parametricity theorems for the raw term can be specified in 
       
   175       the command lift_definition, which allow us to generate stronger
       
   176       transfer rules
       
   177     + setup_lifting generates stronger transfer rules if parametric
       
   178       correspondence relation can be generated
       
   179     + various new properties of the relator must be specified to support
       
   180       parametricity
       
   181     + parametricity theorem for the Quotient relation can be specified
       
   182   - setup_lifting generates domain rules for the Transfer package
       
   183   - stronger reflexivity prover of respectfulness theorems for type
       
   184     copies
       
   185   - ===> and --> are now local. The symbols can be introduced
       
   186     by interpreting the locale lifting_syntax (typically in an
       
   187     anonymous context)
       
   188   - Lifting/Transfer relevant parts of Library/Quotient_* are now in 
       
   189     Main. Potential INCOMPATIBILITY
       
   190   - new commands for restoring and deleting Lifting/Transfer context:
       
   191     lifting_forget, lifting_update
       
   192   - the command print_quotmaps was renamed to print_quot_maps. 
       
   193     INCOMPATIBILITY
       
   194 
       
   195 * Transfer:
       
   196   - better support for domains in Transfer: replace Domainp T 
       
   197     by the actual invariant in a transferred goal
       
   198   - transfer rules can have as assumptions other transfer rules
       
   199   - Experimental support for transferring from the raw level to the
       
   200     abstract level: Transfer.transferred attribute
       
   201   - Attribute version of the transfer method: untransferred attribute

   173 cases rules f.cases and g.cases are generated instead of unusable
   205 cases rules f.cases and g.cases are generated instead of unusable
   174 f_g.cases which exposed internal sum types. Potential INCOMPATIBILITY,
   206 f_g.cases which exposed internal sum types. Potential INCOMPATIBILITY,
   175 in the case that the unusable rule was used nevertheless.

   229 * New Library/FSet.thy: type of finite sets defined as a subtype of
       
   230   sets defined by Lifting/Transfer
