RECENT CHANGES can be tracked at the BOTTOM END.  The rest doesn't qualify
for an exciting story, just skip it.


1.1.1 from earlier releases (incomplete):
	- this file
	- debugging & other conditional compilation parameters have been moved
		to the config file. doc/debug.doc has been rewritten
	- fixed the array size in sss.cc to fit into the 64K DGROUP in DOS
	- fixed shriek() not to be volatile and to always take signed ints
	- allowed (hack) 16-bit ints in load_config and DOS HUGE memory model
	- "make tgz" (in sss/src) makes a tgz (in sss/src/../..) with the
		name sssX-Y-Z.tgz; the version numbers as read from common.h
		A copy is made on the diskette (if one is inserted at the moment).
	- "make date" outputs the last modification time

1.1.2 from 1.1.1	10.5.97
	- "make dos" creates a zipfile, not individual files
	- "make dos1250", "make dos1252" can produce two other encodings
	- in unit::sanity, fixed the range checks for pointer values
	- migrated the rest of non-ASCII chars out of the sources
	- migrated another bunch of options to the .ini file
	- allowed escape sequences and quoted strings in the .ini file
	- multiple tiny code amendments
	- no compile-time checking for the memory model
	- run-time check whether we've been compiled fully 32-bit (again)
	- changed warning flags to -Wall -Wno-parentheses -Wno-unused
	- new option type: DEBUG_AREA (enum, just for focus_dbg)
	- interf.h uglified
	- side syllables hacked out. See unit:syll_break for more info.
		The feature can be disabled in the .ini file (syll_break())
		cfg/nonsyl.dic has been consequently cleaned up.
	- the sonority rule no longer considers nasals as more sonorous than
		the ordinary consonants. Hope it doesn't hurt.
	- parser now can accept keyboard input & other minor improvements there
	- new files in the doc directory: Intro, Files

1.1.3 from 1.1.2	14.5.97
	- enums UNIT, OPT_TYPE suffer formally renamed elements because of Borland
	- BOOL, INT, STR (formerly STRING),... in config.cc are always #defined now
	- a new diphone inventory description (.dph) - the traditional one.
		Very crude, lots of the diphones discarded (incl. W[{>,` etc.)
		This inventory doesn't cover some allophones at all, see default.rul
	- in unit::set_father(), f,i,t will be inherited (untested). This should 
		allow phone-level f,i,t adjustments propagated to the diphones.
	- unit::diph() optionally allows repeated diphones (have a look there).
	- we now allow "triphones" (like "a'a", a.k.a. "a|a" in traditnl.dph)
	- the default rules contain one killer rule (until traditnl.dph is fixed)

1.1.4 from 1.1.3	19.5.97
	- optional hash table profiling; configurable hash table full percentage
	- removed a word-length quadratic complexity aspect of subst() by not 
		checking too long words (longer than hash::longest). Typically,
		this "feature" will cause an overall slowdown. :-)
	- fixed unit::subst to loop until there's nothing to substitute
	- traditnl.dph is less crude now, it only doesn't solve the voiced 
		affricates now. We still never use many important diphones.
	- some big fixed-length auto arrays have been made static & malloced
	- introduced cfg.safe_grow, but still not configurable

1.1.5 from 1.1.4	22.5.97
	- '\0' shall be replaced by '_' in parser::getch; '\0' never gets output.
	- unit::fout is much more configurable now, see config.cc
	- tabs regularized to eight chars

1.1.6 from 1.1.5	27.5.97
	- config.cc #inclusion scheme has been substantially reworked
	- aggregate (array...) config options are now possible, see config.cc
	- unit::fout is even more configurable now. And slower as well.
	- ANSI escape sequences mostly made configurable
	- can remove elements from the hash tables now
	- invalid options are checked against
	- fixed pointer sanity checks (when trusted_ptr==off)
	- added doc/output.doc

1.1.7 from 1.1.6	28.5.97
	- fixed a stupid "last byte swallowing" bug
	- added diphtong rules, made traditnl.dph handle diphtongs better
	- too high level symbols, which could make the parser prematurely
		terminate a substitution, are checked against (parser::done)
	- gather now gathers everything, thus preserving syllables etc.
		during substitutions. This makes work multiple multilevel
		substitutions, such as "ououo" -> "ou|ou|o".
	- prep is temporarily broken

1.1.8 from 1.1.7	29.5.97
	- fixed prep &c (bug having to do with M_EXACT and unit::gather())
	- if a preposition occurs at the end of a colon, let it be fatal
	- added the FILE cfg option type
	- deuglified load_config()


1.2.-1 from 1.1.8	30.5.97
	- converted all printf's to redirectable calls. Use "stddbg_file",
		"stdshriek_file", "stdwarn_file" in sss.ini to redirect them.
		An exception is user_pause(), which should never be redirected
	- renamed sss to ss, 'cause 'tis shorta.
	- colorize() now doesn't check against redirected input
	- rewrote the stuff about ss_init(), multiple .ini files
	- at the very beginning, the debug output may go temporarily
		to the screen. It will be redirected properly after
		the .ini file which uses it is redirected.
	- we now have cfg/ssfixed.ini and ss.ini instead of sss.ini.
		Any values in ss.ini override those in ssfixed.ini. The idea 
		is not to bury the oft-changing params in the permanent ones.
	- the "markup_language" configuration parameter (MUST be located
		in ssfixed.ini!, possible values: none, ansi, rtf) allows
		run-time switching between ANSI output and the Rich Text Format
		output. Either ssansi.ini or ssrtf.ini is processed after
		ssfixed.ini
	- ss_reinit() can be used to re-read the config files. Not fool-proof.
	- ss_init() shall be used instead of load_config()

1.2.0 from 1.2.-1	1.6.97
	- cfg/ssdeflt.ini (used by ss_reinit()) is now automagically generated
		from src/config.cc (on "make")
	- Makefile deuglified a little bit
	- fixed hash::hash (empty lines had been creating phantom items)
	- doc/output.doc includes new topics (e.g. debugging info redirection)
	- fixed safe_grow and max_line_len to be configurable
	- got finally rid of ANSI escape sequences in config.cc
	- made '~' a valid word separator (e.g. in a dictionary)

1.2.1 from 1.2.0	13.6.97
	- fixed some of the silly Borland warnings
	- removed -Wno-parentheses (and fixed some lines which got it)
	- added nnet.cc (neural networks' input - see doc/neuralnet.doc)
	- consistently changed "auxiliary syllable" to "side syllable"
	- changed warning flags to -Wall with no exceptions
	- faked the use of unused function arguments, see unused() in common.h
	- added the "text" abstraction (src/text.*) to handle #include in rules
	- maybe fixed a DOS CR/LF freadin() bug
	- gather() called after the diphones get created now shrieks gracefully

1.2.2 from 1.2.1	 2.7.97
	- no code change, makefile adjusted for the files that were new in 1.2.1

1.2.3 from 1.2.2	 7.7.97
	- minor code changes in text.*, chasing a DOS-only Heisenbug (lost)

1.2.4 from 1.2.3	 14.9.97
	- fixed this==NULL sanity check in unit::sanity()
	- made parser skip any garbage (whitespace?) until the first phone
	- minor amendments to text.cc
	- made hash.cc a little bit more commentproof
	- when DEBUG is defined, free() is #defined to paranoid_free() (see)
	- fixed tmps declaration in rules::str2rule() (the DOS-only bug?)
	- improved cfg/syll.dic (laryngeal stop before word-initial vocals)
	- fixed long vowels in the nnet code (unit::nnet_type())
	- the glottal stop is now a valid voiceless stop for the nnet code

1.2.5 from 1.2.4	29.9.97
	- added doc/COPYING (GNU Public License - copyleft) to fix the legalese
	- the paranoid_free() hack from 1.2.4 has been removed. Because,
	- dmalloc (debugging mem alloc()) library is used #ifdef WANT_DMALLOC
	- fixed a fence-post error (rules::rules::ruleline one byte too short)
	- rules::resolve_vars now uses a pseudostatic buffer (was call-lived)
	- the FOREVER macro should be used to mark permanent memory allocations
	- some minor memory leaks have been found and fixed
	- rewrote hash::hash to make it even more commentproof, but messier
	- "make clean" tries to clean up the Makefile and report some settings
	- cleaned up parser::parser, parser.cc now depends on interf.cc::freadin()

1.2.6 from 1.2.5	29.10.97
	- partly allowed deletion of the last phone in a syllable
	- const char * everywhere to be -Wwrite-strings clean
	- hash collisions are now handled with a balanced AVL tree
	- furthermore, on hash table over/underflow it is completely rehashed
	- made the only nnet.rules substitution not destroy syllables
	- fixed a trailing whitespace bug in hash:hash
	- it is possible to remove the diphones with "DIPHONES ~" rule
	- option to dump the diphones at every DIPHONES rule (immed_diphones)
	- added a punctuation hack into the nnet rules and similar minor fixes

	- invent_dir now points to /usr/lib/ss
	- improved prosody and other rules
