+Revision history for Perl module Unicode::Collate.
+
+0.33 Sat Dec 13 14:07:27 2003
+ - documentation improvement: in "entry", "overrideHangul", etc.
+
+0.32 Wed Dec 3 23:38:18 2003
+ - A matching part from index(), match() etc. will include illegal
+ code points (as well as ignorable characters) following a grapheme.
+ - Contraction with illegal code point will be invalid.
+ - Added some tests in illegal.t; added view.t.
+ - Some tests are separated from test.t into altern.t and rearrang.t.
+ - modified XSUB internals.
+
+0.31 Sun Nov 16 15:40:15 2003
+ - Illegal code points (surrogate and noncharacter; they are definitely
+ ignorable) will be distinguished from NULL ("\0");
+ but porting is not successful in the case of ((Pure Perl) and
+ (Perl 5.7.3 or before)). If perl 5.6.X is used, XSUB may help it
+ in place of broken CORE::unpack('U*') in older perl.
+ - added illegal.t and illegalp.t.
+ - added XSUB (EXPERIMENTAL!) where some functions are implemented
+ in XSUB. Pure Perl is also supported.
+
+0.30 Mon Oct 13 21:26:37 2003
+ - fix: Completely ignorable in table should be able to be overrided
+ by non-ignorable in entry.
+ - fix: Maximum length for contraction must not be shortened
+ by a shorter contraction following in table and/or entry.
+ - added normal.t.
+ - some doc fixes
+
+0.29 Mon Oct 13 12:18:23 2003
+ - now UCA Version 11 (but no functionality is different from Version 9).
+ - supported hangul_terminator.
+ - fix: Base_Unicode_Version falsely returns Perl's Unicode version.
+ C4 in UTS #10 requires UTS's Unicode version.
+ - For variable weighting, 'variable' is recommended
+ and 'alternate' is deprecated.
+ - added version() method.
+ - added hangtype.t, trailwt.t, variable.t, and version.t.
+
+0.28 Sat Sep 06 20:16:01 2003
+ - Fixed another inconsistency under (normalization => undef):
+ Non-contiguous contraction is always neglected.
+ - Fixed: according to S2.1 in UTS #10, a blocked combining character
+ should not be contracted. One test in test.t was wrong, then removed.
+ - Added contract.t.
+ - (normalization => "prenormalized") is able to be used.
+
+0.27 Sun Aug 31 22:23:17 2003
+ some improvements:
+ - The maximum length of contracted CE was not checked (v0.22 to v0.26).
+ Collation of a large string including a first letter of a contraction
+ that is not a part of that contraction (say, 'c' of 'ca'
+ where 'ch' is defined) was too slow, inefficient.
+ - A form name for 'normalization', no longer restricted to
+ /^(?:NF)?K?[CD]\z/, will be allowed as long as
+ Unicode::Normalize::normalize() accepts it, since Unicode::Normalize
+ or UAX #15 may be changed/enhanced in future.
+ - When Hangul syllables are decomposed under <normalization => undef>,
+ contraction among jamo (LV, VT, LVT) derived from the same
+ Hangul syllable is allowed. Added hangul.t.
+
+0.26 Sun Aug 03 22:23:17 2003
+ - fix: an expansion in which a CE is level 3 ignorable and others are not
+ was wrongly made level 3 ignorable as a whole entry.
+ (In DUCET, some precomposites in Musical Symbols are so)
+
+0.25 Mon Jun 06 23:20:17 2003
+ - fix Makefile.PL.
+ - internal tweak (again): pack_U() and unpack_U().
+
+0.24 Thu Apr 02 23:12:54 2003
+ - internal tweak for (?un)pack 'U'.
+
+0.23 Wed Sep 04 19:25:20 2002
+ - fix: scalar match() no longer returns an lvalue substr ref.
+ - fix: "Ignorable after variable" should be made level 3 ignorable
+ even if alternate => 'blanked'.
+ - Now a grapheme may contain trailing level 2, level 3,
+ and completely ignorable characters.
+
+0.22 Mon Sep 02 23:15:14 2002
+ - New File: index.t.
+ (The new test.t excludes tests for index.)
+ - tweak on index(). POSITION is supported.
+ - add match, gmatch, subst, gsubst methods.
+ - fix: ignorable after variable in 'shift'-variable weight.
+
+0.21 Sat Aug 03 10:24:00 2002
+ - upgrade keys.txt and t/test.t for UCA Version 9.
+
+0.20 Fri Jul 26 02:15:25 2002
+ - now UCA Version 9.
+ - U+FDD0..U+FDEF are new non-characters.
+ - fix: whitespace characters before @backwards etc. in a table file.
+ - now values for 'alternate', 'backwards', etc.,
+ which are explicitly specified via new(),
+ are preferred to those specified in a table file.
+
+0.12 Sun May 05 09:43:10 2002
+ - add new methods, ->UCA_Version and ->Base_Unicode_Version.
+ - test fix: removed the needless requirement of Unicode::Normalize.
+ [reported by David Hand]
+
+0.11 Fri May 03 02:28:10 2002
+ - fix: now derived collation elements can be used for Hangul Jamo
+ when their weights are not defined.
+ [reported by Andreas J. Koenig]
+ - fix: rearrangements had not worked.
+ - mentioned pleblem on index() in BUGS.
+ - more documents, more tests.
+ - tag names for 'alternate' are case-insensitive (i.e. 'SHIFTed' etc.).
+ - The <undef> value for the keys "overrideCJK", "overrideHangul",
+ "rearrange" has a special behavior (different from default).
+
+0.10 Tue Dec 11 23:26:42 2001
+ - now you are allowed to use no table file.
+ - fix: fetching CE with two or more combining characters.
+
+0.09 Sun Nov 11 17:02:40:18 2001
+ - add the following methods: eq, ne, lt, le, gt, le.
+ - relies on &Unicode::Normalize::getCombinClass()
+ in place of %Unicode::Normalize::Combin
+ (the hash is not defined in the XS version of Unicode::Normalize).
+ then you should install Unicode::Normalize 0.10 or later.
+ - now independent of Lingua::KO::Hangul::Util
+ (this module does decomposition of Hangul syllables for itself)
0.08 Mon Aug 20 22:40:18 2001
- add the index method.
