=============
2.9.2 - January 4, 2002
The Logtalk compiler can now print a warning when compiling source files
that use non-ISO defined built-in predicates using a new portability/1
compiler option. Updated the relevant sections of the user manual and the
errors example.
Corrected a compiler bug where the entity relation tables only recorded
the last entry per entity relation type.
Updated config file for CIAO 1.7#162.
2.9.1 - December 5, 2001
Logtalk compiler now prints a warning when redefining or replacing an
existing entity.
Corrected a compiler bug in the error checking code for the info/1
and info/2 directives.
Changed the order of object loading in the "mi" example to avoid
suporious warning messages.
Added a new problem ("bridge") to the "searching" example. Improved
"performance" monitor to give correct reports on alternative solutions.
Corrected a bug in the "water jug" state space example.
2.9.0 - October 22, 2001
Added config files for CIAO Prolog 1.7p115 and B-Prolog 6.0.
Compiling and loading an entity that contains references to unknown
entities (by default) prints a warning. Updated user and reference
manuals.
Rewrited all the compiler warning/error code and output messages.
Changed compiled code functors postfixes from "_sdcl" and "_sdef" to
"_idcl" and "_idef" (implies recompilation of all objects, protocols,
and categories).
Changed all occurrences and references to the term "entity_scope" to
"scope".
Removed some redundant productions from the Logtalk grammar.
Updated documentation on the xml directory. Renamed some of the .xsl
files. Added sample scripts to batch convert .xml files to .html files.
Added a new loader utility file, all.loader, to load all library files
loaded by the other loader files.
Started work on documenting the Logtalk pre-processor/compiler source
file.
New "errors" example. Updated the "inheritance" example.
2.8.4 - March 9, 2001
