0.0.1
	. First version. Does not work with LaTeX's cross references

0.0.2
	. Add \protect's to for working with LaTeX's cross references.

... ...

0.0.8
	. Handle punctuation chars

0.1.0

0.2.0
	. Support for CJK fonts

0.2.4
	. Change interword space to 0pt plus 0.03\ccwd minus 0.02\ccwd if
	  CJK mode.

0.3.0	
	. Use skip for interword glue instead of space, renable \ziju command,

	. Set \lccode and \uccode of chars 0x80-0xFF to 0 to prevent
	  \MakeUppercase from modifying Chinese characters (this only works
	  for GB2312 encoding, since with GBK encoding the second byte may
	  be in the range 0x40-0x7E).

0.3.1
	. Change some formats of the CCT.cfg file.

	. Use \CCTnospace by default.

0.3.3
	. Add a hack for dealing with the special characters '{', '}', '\', '^'
	  by mapping them to '0', '1', '2', '3', respectively.

	. Create cctconv.c, only needed with GBK chars whose second byte is
          one of '\\', '{', '}', '^'.

0.3.4
	. cctconv.c: '_' -> '4', '~' -> '5' (for hyperref PDF bookmarks)

	. Force CJK mode if PDFTeX/PDFLaTeX

	. Add support for CJK's ^^7f hook.

	. Create cctbm.c for postprocessing of hyperref PDF bookmarks
	  file (.out), only needed with GBK chars whose second byte is
	  '\\', '{', '}', '^', '_', or '~'.
	  Note ZLB: it is now obsoleted by gbk2uni.c

	. Create shell script 'ccttex'

0.4.0
	. Add \CCTtilde, \nbs, \standardtilde

	. Rewriting of ^^7f, \@CCTMapChar macros,
	  add \CCTchar macro.

	  CCT's preprocessor inserts '~' for a non break space,
	  thus calling \CCTtilde in a document processed by the preprocessor
	  might generate linebreaks at undesirable places (E.g., the comma
	  on line 496 in cctch2.ctx). cctinit.c is modified for this purpose,
	  and the new 'cchead.sty' redefines '~' in the \CC macro.
