 =============
 
 
+2.30.7 - November 5, 2007
+
+	Updated the multi-threading built-in predicates threaded_notify/1 and 
+	threaded_wait/1 to accept lists of notifications.
+
+	Added a new read-only compiler flag, "context_switching_calls", allowing 
+	context switching calls to be disabled (they are enabled by default).
+
+	Updated the B-Prolog config file to recognize eager_consume/1 directives.
+	Updated the XSB config file to recognize use_subsumptive_tabling/1,
+	use_variant_tabling/1, index/1, thread_private/1, and thread_shared/1 
+	directives.
+	Updated the YAP config file to recognize thread_local/1 directives.
+	Updated the SICStus Prolog config files to recognize volatile/1 directives.
+	Updated the SWI-Prolog config file to recognize thread_local/1, index/1, 
+	and hash/1 directives.
+
+	Changed the backup directory names generated by the "cplgtdirs.*" shell 
+	scripts to not include whitespace characters.
+
+	Updated the "xsbmtlgt.sh" integration script to start XSB-MT using the 
+	new command-line option "--shared_predicates" (requires current XSB CVS 
+	version). Updated the Windows GUI installer to support running Logtalk 
+	with XSB-MT.
+
+	Added a multi-threading example, "barriers", of barrier synchronization.
+
+	Updated the "functions" example sample queries for compatibility with the 
+	ISO Prolog standard regarding representation of float numbers.
+
+	Added a workaround for a parsing bug in XSB while compiling the "sicstus" 
+	example.
+
+
+2.30.6 - October 21, 2007
+
+	Replaced calls to the proprietary current_thread/2 predicate in the 
+	Logtalk runtime by calls to the thread_property/2 predicate as per 
+	the ISO DTR on multi-threading predicates. Added a goal_expansion/2 
+	clause to the SWI-Prolog config file to automatically switch between 
+	the current_thread/2 and thread_property/2 predicates depending on 
+	availability.
+
+	Changed handling of the encoding/1 directive by the Logtalk compiler in 
+	order to improve compatibility with YAP and SICStus Prolog. Removed from 
+	the config files the now obsolete '$lgt_set_stream_encoding'/2 predicate 
+	definition. Renamed the compiler option "supports_encoding_dir" to 
+	"encoding_directive" and changed its possible values to "unsupported", 
+	"full" (used in both Logtalk source files and compiler generated Prolog 
+	files), and "source" (used only in Logtalk source files).
+
+	Renamed compiler option "underscore_vars" to "underscore_variables".
+	Renamed compiler option "supports_break_predicate" to "break_predicate".
+
+	Improved the performance of recursive predicate definitions synchronized 
+	by mutexes. Explicitly create all mutexes used by an entity at load time 
+	for compatibility with XSB. Several changes to multi-threading support in 
+	order to improve compatibility with current and forthcoming versions of 
+	YAP, SWI-Prolog, and XSB.
+
+	Updated the Logtalk compiler for compatibility with both logical and 
+	immediate update semantics when compiling synchronized predicates.
+
+	Updated the meta-predicate compilation sanity checks to verify the 
+	existence of the minimum number of normal arguments in a clause head 
+	required by the closure of maximum arity.
+
+	Added a workaround for the lack of built-in support for character 
+	unbuffered input when using the Logtalk built-in debugger to the config 
+	files of ALS Prolog, B-Prolog, Ciao, CxProlog, IF/Prolog, JIProlog, 
+	Prolog II+, SICStus Prolog, XSB, and YAP. Thanks to Parker Jones for the 
+	bug report.
+
+	Updated the YAP config file to auto-detect working Unicode support when 
+	setting the "encoding_directive" compiler option.
+
+	Updated the XSB config file to auto-detect multi-threading support
+	when setting the "threads" compiler option. Added an integration script 
+	(xsbmtlgt.sh) and supporting files for the multi-threaded version of XSB 
+	(requires current development version, available from the XSB CVS server).
+
+	Added a MacPorts portfile for building MacOS X installer packages.
+
+	Added a BOM to the "babel.lgt" UTF-8 file in the "encodings" example in 
+	order to improve compatibility with SICStus Prolog.
+
+	Updated the library object "random" by replacing the synchronized/0 
+	directive by a synchronized/1 directive listing only the predicates 
+	that modify the random number seed.
+
+	Added syntax coloring support for the GtkSourceView 2.x text widget 
+	(used e.g. on the Gnome's Gedit text editor and on the MonoDevelop IDE).
+	Removed syntax coloring for the obsolete atomic/1 predicate directive 
+	from the support files of Source-highlight, Emacs, SubEthaEdit, jEdit, 
+	and Kate. Optimized the regular expressions used in most syntax coloring 
+	configuration files of supported text editors.
+
+
+2.30.5 - September 19, 2007
+
+	Added new multi-threading built-in predicates threaded_call/2, 
+	threaded_once/2, threaded_exit/2, and threaded_peek/2. These new 
+	predicates support the use of threaded call identifier tags in order to 
+	link specific threaded_call/2 and threaded_once/2 calls to specific 
+	threaded_exit/2 and threaded_peek/2 calls. Extended the "nondet" example 
+	in order to illustrate the new functionality.
+
+	Changed the implementation of the built-in predicate threaded_exit/1 in 
+	order to avoid blocking when its argument is subsumed by the argument of 
+	the corresponding threaded_call/1 call instead of being a variant.
+
+	Updated the Logtalk compiler to encapsulate resource errors inside 
+	error/2 exception terms (as specified in the ISO Prolog core standard).
+
+	Corrected a bug in the library object "lgtunit" (wrong arity on two 
+	failed_test/2 predicate calls).
+
+	Corrected two problems with the "testing" example: a wrong call on the 
+	object "dyn_tests" and a missing entry in the "libpaths.pl" file. Removed 
+	two pointless dynamic predicate directives in the "buffer" example.
+
+	Improved documentation of multi-threading programming and predicate 
+	properties. Corrected the reference manual page describing the threaded/0 
+	directive.
+
+	Simplified installation scripts by moving shared distribution cleaning 
+	code into the "cleandist.sh" script. Updated the "install.sh" script to 
+	set the installation prefix to "/usr" on Debian systems. Updated the 
+	Linux RPM spec file in order to clean the building directory after the 
+	package creation.
+
+
+2.30.4 - August 22, 2007
+
+	Allow the argument of {}/1 calls to be a variable at compile time.
+
+	Updated the Qu-Prolog config file to match and require version 8.1 and 
+	added a "qplgt" integration script.
+
+	Updated the XSB config file to match and require version 3.1 and to 
+	take advantage of the compiler option optimize/1 when loading Logtalk 
+	generated Prolog intermediate files.
+
+	Added a new library object, "lgtunit", providing preliminary support for 
+	writing and running unit tests. Added a new example, "testing", defining 
+	sample unit tests.
+
+	Added a new multi-threading example, "threads/tak", implementing the 
+	Takeuchi function (recursive arithmetic).
+
+	Updated the "threads/philosophers" example to use notifications instead 
+	of a dynamic predicate for representing chopstick availability. Added an 
+	alternative implementation using a parametric object. Improved example 
+	documentation.
+
+	Updated the "benchmarks" example to allow comparisons between calls to 
+	imported category predicates and calls to local object predicates.
+
+	Updated Emacs support in order to fix problems with the syntax-coloring 
+	of some Logtalk built-in predicates and applied a patch contributed by 
+	Nicolas Pelletier to workaround a compatibility problem with XEmacs.
+
+	Updated jEdit support in order to fix a problem with the syntax-coloring 
+	of the :/1 control construct.
+
+
+2.30.3 - July 9, 2007
+
+	Updated the multi-threading built-in predicate threaded/1 to support 
+	both conjunctions of goals (akin to and-parallelism) and disjunctions 
+	of goals (akin to or-parallelism) as an argument.
+
+	Removed the experimental threaded_race/1 multi-threading built-in 
+	predicate (its or-parallelism functionality is subsumed by the updated 
+	threaded/1 predicate).
+
+	Corrected a bug in the implementation of the multi-threading built-in 
+	predicate threaded_exit/1 when there are more than one thread running 
+	the same non-deterministic goal (the fix ensures that all alternative 
+	solutions per threaded_exit/1 call come from the same computing thread). 
+	Thanks to Paul Crocker for the suggested bug fix solution.
+
+	Updated the sample queries in the "threads/buffer"/SCRIPT.txt" file to 
+	match the updated entities in the example.
+
+	Updated the "threads/functions" example to use the new version of the 
+	threaded/1 multi-threading built-in predicate.
+
+
 2.30.2 - June 24, 2007
 
 	Updated the Logtalk compiler to throw a compilation error when duplicated
