1Revision history for Perl module Unicode::Collate.
2
30.52  Thu Oct 13 21:51:09 2005
4    - The Unicode::Collate->new method does not destroy user's $_ any longer.
5      (thanks to Jon Warbrick for bug report)
6
70.51  Sun May 29 20:21:19 2005
8    - Added the latest DUCET (for Unicode 4.1.0) as Collate/allkeys.txt,
9      which is not required to test this module.
10      Please notice that allkeys.txt will be overwritten if you have had
11      other allkeys.txt already.
12    - Added INSTALL section in POD.
13
140.50  Sun May  8 20:26:39 2005
15    - Now UCA Revision 14 (based on Unicode 4.1.0).
16    - Some tests are modified.
17    - Added cjkrange.t, ignor.t, override.t.
18    - Added META.yml.
19
200.40  Sat Apr 24 06:54:40 2004
21    - Now a table file is searched in @INC.
22
230.33  Sat Dec 13 14:07:27 2003
24    - documentation improvement: in "entry", "overrideHangul", etc.
25
260.32  Wed Dec  3 23:38:18 2003
27    - A matching part from index(), match() etc. will include illegal
28      code points (as well as ignorable characters) following a grapheme.
29    - Contraction with illegal code point will be invalid.
30    - Added view.t.
31    - Added some tests in illegal.t.
32    - Some tests are separated from test.t into altern.t and rearrang.t.
33    - modified XSUB internals.
34
350.31  Sun Nov 16 15:40:15 2003
36    - Illegal code points (surrogate and noncharacter; they are definitely
37      ignorable) will be distinguished from NULL ("\0");
38      but porting is not successful in the case of ((Pure Perl) and
39      (Perl 5.7.3 or before)). If perl 5.6.X is used, XSUB may help it
40      in place of broken CORE::unpack('U*') in older perl.
41    - added illegal.t and illegalp.t.
42    - added XSUB (EXPERIMENTAL!) where some functions are implemented
43      in XSUB. Pure Perl is also supported.
44
450.30  Mon Oct 13 21:26:37 2003
46    - fix: Completely ignorable in table should be able to be overrided
47      by non-ignorable in entry.
48    - fix: Maximum length for contraction must not be shortened
49      by a shorter contraction following in table and/or entry.
50    - added normal.t.
51    - some doc fixes
52
530.29  Mon Oct 13 12:18:23 2003
54    - now UCA Version 11 (but no functionality is different from Version 9).
55    - supported hangul_terminator.
56    - fix: Base_Unicode_Version falsely returns Perl's Unicode version.
57      C4 in UTS #10 requires UTS's Unicode version.
58    - For variable weighting, 'variable' is recommended
59      and 'alternate' is deprecated.
60    - added version() method.
61    - added hangtype.t, trailwt.t, variable.t, and version.t.
62
630.28  Sat Sep 06 20:16:01 2003
64    - Fixed another inconsistency under (normalization => undef):
65      Non-contiguous contraction is always neglected.
66    - Fixed: according to S2.1 in UTS #10, a blocked combining character
67      should not be contracted. One test in test.t was wrong, then removed.
68    - Added contract.t.
69    - (normalization => "prenormalized") is able to be used.
70
710.27  Sun Aug 31 22:23:17 2003
72      some improvements:
73    - The maximum length of contracted CE was not checked (v0.22 to v0.26).
74      Collation of a large string including a first letter of a contraction
75      that is not a part of that contraction (say, 'c' of 'ca'
76      where 'ch' is defined) was too slow, inefficient.
77    - A form name for 'normalization', no longer restricted to
78      /^(?:NF)?K?[CD]\z/, will be allowed as long as
79      Unicode::Normalize::normalize() accepts it, since Unicode::Normalize
80      or UAX #15 may be changed/enhanced in future.
81    - When Hangul syllables are decomposed under <normalization => undef>,
82      contraction among jamo (LV, VT, LVT) derived from the same
83      Hangul syllable is allowed.  Added hangul.t.
84
850.26  Sun Aug 03 22:23:17 2003
86    - fix: an expansion in which a CE is level 3 ignorable and others are not
87      was wrongly made level 3 ignorable as a whole entry.
88      (In DUCET, some precomposites in Musical Symbols are so)
89
900.25  Mon Jun 06 23:20:17 2003
91    - fix Makefile.PL.
92    - internal tweak (again): pack_U() and unpack_U().
93
940.24  Thu Apr 02 23:12:54 2003
95    - internal tweak for (?un)pack 'U'.
96
970.23  Wed Sep 04 19:25:20 2002
98    - fix: scalar match() no longer returns an lvalue substr ref.
99    - fix: "Ignorable after variable" should be made level 3 ignorable
100           even if alternate => 'blanked'.
101    - Now a grapheme may contain trailing level 2, level 3,
102      and completely ignorable characters.
103
1040.22  Mon Sep 02 23:15:14 2002
105    - New File: index.t.
106      (The new test.t excludes tests for index.)
107    - tweak on index(). POSITION is supported.
108    - add match, gmatch, subst, gsubst methods.
109    - fix: ignorable after variable in 'shift'-variable weight.
110
1110.21  Sat Aug 03 10:24:00 2002
112    - upgrade keys.txt and t/test.t for UCA Version 9.
113
1140.20  Fri Jul 26 02:15:25 2002
115    - now UCA Version 9.
116    - U+FDD0..U+FDEF are new non-characters.
117    - fix: whitespace characters before @backwards etc. in a table file.
118    - now values for 'alternate', 'backwards', etc.,
119      which are explicitly specified via new(),
120      are preferred to those specified in a table file.
121
1220.12  Sun May 05 09:43:10 2002
123    - add new methods, ->UCA_Version and ->Base_Unicode_Version.
124    - test fix: removed the needless requirement of Unicode::Normalize.
125      [reported by David Hand]
126
1270.11  Fri May 03 02:28:10 2002
128    - fix: now derived collation elements can be used for Hangul Jamo
129      when their weights are not defined.
130      [reported by Andreas J. Koenig]
131    - fix: rearrangements had not worked.
132    - mentioned pleblem on index() in BUGS.
133    - more documents, more tests.
134    - tag names for 'alternate' are case-insensitive (i.e. 'SHIFTed' etc.).
135    - The <undef> value for the keys "overrideCJK", "overrideHangul",
136      "rearrange" has a special behavior (different from default).
137
1380.10  Tue Dec 11 23:26:42 2001
139    - now you are allowed to use no table file.
140    - fix: fetching CE with two or more combining characters.
141
1420.09  Sun Nov 11 17:02:40:18 2001
143    - add the following methods: eq, ne, lt, le, gt, le.
144    - relies on &Unicode::Normalize::getCombinClass()
145      in place of %Unicode::Normalize::Combin
146      (the hash is not defined in the XS version of Unicode::Normalize).
147      then you should install Unicode::Normalize 0.10 or later.
148    - now independent of Lingua::KO::Hangul::Util
149      (this module does decomposition of Hangul syllables for itself)
150
1510.08  Mon Aug 20 22:40:18 2001
152    - add the index method.
153
1540.07  Thu Aug 16 23:42:02 2001
155    - rename the module name to Unicode::Collate.
156
1570.06  Thu Aug 16 23:18:36 2001
158    - add description of the getSortKey method.
159
1600.05  Mon Aug 13 22:23:11 2001
161    - bug fix: on the things of 4.2.1, UTR #10
162    - getSortKey returns a string, but not an arrayref.
163
1640.04  Mon Aug 13 22:23:11 2001
165    - some bugs are fixed.
166    - some tailoring parameters are added.
167
1680.03  Mon Aug 06 06:26:35 2001
169    - modify README
170
1710.02  Sun Aug 05 20:20:01 2001
172    - some fix
173
1740.01  Sun Jul 29 16:16:15 2001

176      with options -A -X -n Sort::UCA
