List of Changes since Version 0.1

• Added a STABLE_RANDOM configuration option. When enabled, the interpreter will use a fixed algorithm to generate random numbers, allowing log files to be created that will work on any system.
• In the "tests" directory there are now log files that play through The Multi-dimensional Thief and Shades of Gray to completion. The intention is to add further log files for other games in time, as tests of the interpreter. Note that the above STABLE_RANDOM configuration option must be turned on to use these log files.
• Substitutions generated by the interpreter's main loop are handled correctly. For example, dying in Shades of Gray no longer results in a "$You$ have died" message.
• Metacommands overriding two-word synonyms built into the interpreter (such as GET OUT, which is a synonym for OUT) are handled.
• The ability of metacommands to use expansions like $noun$ has been enabled for the AGT 1.5 variants.
• The logic to set up roomflags when reading from DA1 files was not quite right. This has been fixed, and has been enabled for the AGT 1.5 variants. As a result, The Multi-dimensional Thief is finishable. Note that if you have a version of a game affected by this change as an AGX file, you will need to re-generate the AGX file from the original AGT data files.
• The version of AGT used by Shades of Gray can override SCREAM in a dummy verb.
• The order in which dummy verbs are scanned when parsing now better matches the order used in the original AGT interpreters.
• Smart disambiguation is on by default for AGT 1.5 and later.
• For pre-Magx games, GetNumberInput always returns a number in the range of a 16-bit signed integer, that is, between -32768 and 32767.

• Fixed output function: paragraph filling corrected; made filling less agressive for Magx games; fixed print_statline to work with a screen width greater than 100.
• Object loops more carefully trapped, avoiding infinite loops. Object loop error no longer printed out.
• IsWorn and IsCarried no longer look inside closed objects. [Al]
• Fixed handling of AGT_DEBUG_CMD by agt_newgame(). [Kinder]
• *nix port changes: MORE handling fixed; os_linux.c renamed os_termcap.c; os_curses.c is now the main *nix interface; os_curses version of fix_loc() fixed; os_curses batch support fixed.
• 32-Bit DOS port: BIOS option now works.
• Fixed formatting in debugger object editor.

• The interpreter will now work correctly when passed an AGT file name with an extension (instead of trying to read it as an AGX file).
• Overhauled STANDARD message handling: ATTACK messages will now get the $noun$ and $object$ in the right order; parser messages now replaceable; $noun$-type substitutions are prevented in cases where they are not meaningful; added message fallback system to stdmsg(); added '-s' command line option for debugging standard messages; added $the_name$, $name_pro$, $name_indir$; fixed capitalization of proper $name$s; $/# substitution routines simplified.
• Debugger now supports objprops, objflags, and PROPER.
• New metacommand tokens: CanGo and MoveInDirection.
• Added support for printing objprops and objflags.
• Added support for itemized objprops/variables/objflags/flags.
• Added support for explicit objects to redirection and command headers.
• Null NOUN/OBJECT/ACTOR args to conditional tokens will no longer generate GAME ERROR messages.
• Added $ and # expansion to shortdescs of nouns and creatures.
• Misc bug fixes:initialization of seen and proper for original AGT games; types in GAME ERROR messages; objswap in exec_verb(); parse_noun will no longer look for multiple nouns when parsing the actor; possible buffer overrun in wordcode_match; added second line of vb== conditions to verify_scope.
• Overhauled handling of dobj_rec, iobj_rec, actor_rec: they are now copied and freed by runverbs() and objcheck_cycle(); added copy_parserec(), free_all_parserec();
• Fixed e-mail address and Jay's URL.

• Added support for proper names of creatures and nouns, indicated by the object in question having the PROPER flag set. Proper names are printed capitalized and without the definite article ("Fred" instead of "the fred"). Note that this change only affects built-in messages, and game messages that use the new $the_n$, $the_o$, and $the_c$ substitutions.
• As part of this change, added the PROPER_CREATURE configuration option which will make *all* creature names proper.
• For pre-Magx games, built-in verb synonyms now take precedence over author-defined ones. For example, N will now be interpretered as NORTH, even in games that try to redefine it as meaning "NO". (Games created using VERSION MAGX will still honor the author's intent.)
• PLAY WITH is longer automatically converted to PLAY. [Metcalf]
• TURN ON can now trigger specials [Metcalf]; in general, the handling of <verb> <preposition> <noun> constructions for pre-Magx games has been fixed.

• Corrected handling of RoomNeedsLight.
• Bugs fixed: direct address with multiple actors of same name, "start==-1" problem in agtread.c, objname handling of missing adjectives, object.c problems with creatureless games, agtout display of non-printable owner-ids, BeforeCommand/AfterCommand handling during disambiguation, premature closing of the description file in agt2agx (giving a "Bad file number" error under DOS), DOS memory allocation error ("Failed Assertion: size>=0" when loading games with 500 or more nouns), and a couple of typos in game messages.
• Fixed PUSH error message handling and compute_addr diagnostics [Patch submitted by Paul Mikell].

• OncePerTurn now triggers on _last_ object in a list if called from AFTER or COMMAND AFTER block. Furthermore, AfterCommand is now true in a COMMAND AFTER block.

• Save and restore were rewritten to use the same file I/O code as the AGX routines; savefmt.h no longer exists. This seems to have fixed the bug with RESTART and UNDO overwriting the dictionary under DOS.
• Save, restore, script, and log files now add an extension automatically.
• Both the interpreter and agttest.c have been modified slightly to work with the new file format and a new program, agt2agx, has been added to convert AGT files to the AGX format.

• Replace fixchar() and IBM character set translations by a look-up table to speed up reading of descriptions.
• Tweaked room description printing so SPECIALS that send you to the same room don't cause the room description to be printed out again.
• For Master's Edition games, now set have_meta flag based on last_cmd rather than on the value in the DA1 file (which is always true for ME games even if there are no metacommands).
