 =============
 
 
+2.27.0 - February 9, 2006
+
+	Improved performance for local calls to the built-in methods phrase/2-3.
+	Allow the built-in methods phrase/2-3 to accept both partial and proper 
+	lists of terminals.
+
+	Improved grammar rule translator. Report calls to undefined non-terminals 
+	when translating grammar rules.
+
+	Added support for declaring grammar rule non-terminal aliases using the 
+	alias/3 directive.
+
+	Added a new predicate property, non_terminal/1, for predicates resulting 
+	from the compilation of grammar rule non-terminals.
+
+	Improved support for the built-in method expand_term/2 in order to allow 
+	bypassing of the default Logtalk grammar rule translator by defining 
+	clauses for the term_expansion/2 predicate. Added a "term_expansionp" 
+	protocol to the Logtalk library. Added a new example, "expansion", 
+	illustrating the use of the term_expansion/2 predicate.
+
+	Added a new compiler flag, hook/1, allowing the specification of a 
+	compiler hook that is called for which term read from a source file.
+	Added a simple example, "hooks", of using the Logtalk compiler hook 
+	to expand author abbreviations in info/1 directives into full names 
+	and email addresses.
+
+	Added support for XSB 3.x to the runtime error handler. Updated the XSB 
+	3.x config file with declarations for multi-threading meta-predicates.
+	
+	Removed a few choice-points when checking validity of entity directives.
+
+	Added two new objects, list(Type) and set(Type), to the standard library 
+	supporting the validation of lists and ordered sets whose elements are 
+	restricted to a single type.
+
+	Added a new DCG example for solving enigmas encoded using a cellphone 
+	keypad.
+
+	Added a missing library dependency to the "puzzles" example SCRIPT file.
+
+	Removed the experimental "systemp.lgt" protocol from the list of files 
+	loaded by the "library/all_loader.lgt" loader utility files to avoid 
+	compilation errors on some Prolog systems.
+
+	Corrected a bug that prevented dynamic creation of categories using the 
+	built-in predicate create_category/4.
+
+	Corrected a bug in the reporting of singleton variables, which failed to 
+	write an accurate message for facts and grammar rules.
+
+	Corrected a bug in passing the correct calling context ("this") when 
+	processing meta-calls in objects.
+
+	Corrected a bug in scope checking with local calls to reflection and 
+	database methods.
+
+	Corrected a bug in checking the validity of the arguments of the op/3 
+	directive appearing inside entities.
+
+	Added predicates for testing if a term is a partial list or a proper list 
+	to all config files.
+
+	Added a definition for missing open/4 ISO Prolog predicate to the config 
+	file of Bin Prolog.
+
+	Added a workaround for a B-Prolog bug to this compiler config file.
+
+
 2.26.2 - December 20, 2005
 
 	Improved error-checking for the Logtalk compiler and for the grammar rule
