 =============
 2.23.1 - March 7, 2005
 	Simplified message sending compilation, improving performance of both 
 	entity compilation and runtime top-level message sending.
 	Simplified implementation and improved performance of the built-in method 
 	current_predicate/2.
 	Updated the runtime error handler for top-level ::/2 calls to recognize 
 	non-existing predicate exceptions thrown by XSB, SICStus Prolog, CIAO, 
 	B-Prolog, and recent development versions of SWI-Prolog. Rewritten the 
 	::/2 predicate in order to minimize the overhead of the catch/3 calls 
 	associated with the runtime error handler, thus improving performance.
 	Expanded the benchmarks example to test performance of the built-in 
 	database methods.
 	Lookup caches are now cleaned before loading a redefined entity in order 
 	to avoid potential problems with entity initialization goals containing 
 	message sending calls (previous versions cleaned the caches only after 
 	entity loading).
 	When reloading an object, its tables of dynamic predicate declarations 
 	and dynamic predicate definitions are now reseted.
 	Corrected a compatibility problem with the "birds" example due to the use 
 	of an operator not available in some Prolog compilers.
 2.23.0 - February 21, 2005
 	Optimized the code generated for local calls to the built-in predicates

 Logtalk version 2.22.5 adds new predicates to all config files (consult the 
 release notes for details). If you are using custom config files, be sure to 
 update them by coping the definition of the new predicates.
 Logtalk version 2.23.0 features new, optimized implementations of the database
 built-in methods, implying recompilation of all objects, protocols, and categories.
