10 This release is just for bug fixing.
13 * Changes in the m17n library 1.6.2
15 This release is just for bug fixing.
18 * Changes in the m17n library 1.6.1
20 ** Libtool 1.5.26 can be used to build the library from CVS source.

27 mflt_enable_new_feature
28 mflt_iterate_otf_feature
33 * Changes in the m17n library 1.5.5
35 ** Now libtool 2.2.4 or the later is required to build the library
39 * Changes in the m17n library 1.5.4

45 * Changes in the m17n library 1.5.3
47 This release is just for bug fixing.
50 * Changes in the m17n library 1.5.2
52 This release is just for bug fixing.
55 * Changes in the m17n library 1.5.1
57 This release is just for bug fixing.
60 * Changes in the m17n library 1.5.0
62 ** New API layer FLT is created.
64 ** New environment variable MDEBUG_FLT is available to turn on
65 printing debug information for FLT, and these are now obsolete;
66 MDEBUG_FONT_FLT, MDEBUG_FONT_OTF.
68 ** New functions mchartable_min_char () returns the mininum character.
69 that is set some value in a char-table. New funcion
70 mchartable_min_char () is for the maximum character.
73 * Changes in the m17n library 1.4.0
75 ** If the environment variable "M17NDIR" is not set, the directory
76 "~/.m17n.d" is serched for database files.
78 ** New function mfont_list_family_names () returns a list of available
81 ** New functions mlanguage_list (), mlanguage_code (),
82 mlanguage_name_list (), and mlanguage_text () return various
83 language-related information.
85 ** New functions mscript_list () and mscript_language_list () return
86 various script-related information.
88 ** New function msymbol_put_func (), msymbol_get_func (),
89 mplist_put_func (), mplist_get_func (), mface_put_hook (), and
90 mface_get_hook () are available to avoid unsafe casting of function
91 pointer. New macro M17N_FUNC and new type M17NFunc are also
95 * Changes in the m17n library 1.3.0
97 ** The `configure' script accepts the argument "--without-gui" to
98 suppress building GUI libraries.
100 ** The environment variable MDEBUG_OUTPUT_FILE can specify a file to
101 output the debugging log messages.
103 ** The member `candidate_changed' of MInputContext carries more
104 information; i.e. the list itself is changed, only an index is
107 ** The member `callback_list' of MInputDriver can have callback
108 functions `input-get-surrounding-text' and
109 `input-delete-surrounding-text'.
111 ** The minput_filter () function accepts special events
112 `input-focus-move', `input-focus-in', and `input-focus-out'.
114 ** Three letter codes of ISO639-2 are also accepted as language
117 ** New functions minput_get_description (), minput_get_commands (),
118 minput_assign_command_keys (), minput_get_variables (), and
119 minput_set_variable(), minput_get_title_icon() are introduced for
120 handling input methods.
122 ** New fucntions mtext_insert () and and mtext_replace () for
125 ** New functions mtext_uppercase (), mtext_titlecase (),
126 mtext_lowercase () implement "3.13 Default Case Operations" of The
127 Unicode Standard 4.0.
129 ** New function mtext_line_break () implements the line breaking
130 algorithm of The Unicode Standard 4.0 UAX#14. The algorithm can be
131 controlled by the variable mdraw_line_break_option.
133 ** New function msymbol_is_managing_key () checks if a symbol is a
136 ** New function mtext_data () exports various information about
139 ** Function mfont_get_prop () accept properties `fontfile',
140 `font-acsent', `font-descent', and `max-advance'.
142 ** New function mfont_check () checks if a specific font can be used
143 for a specific script and language.
145 ** New function mface_equal () checks if two faces are equal or not.
148 * Changes in the m17n library 1.2.0
150 ** Two new variables MTEXT_FORMAT_UTF_16 and MTEXT_FORMAT_UTF_32.
151 They are initialized to one of MTEXT_FORMAT_UTF_16LE,
152 MTEXT_FORMAT_UTF_16BE, MTEXT_FORMAT_UTF_LE, MTEXT_FORMAT_UTF_32BE
153 dependending on the systems's endianess.
155 ** In the argument PLIST of mframe (), the key Mfont can be used to
156 specify which font-backend to use. The value must be Mx or Mfreetype.
158 ** New function mfont_list () returns a list of matching fonts.
160 ** New function m17n_status () returns the current initialization
163 ** New function minput_reset () resets the current input context.
165 ** Names of sample programs have prefix "m17n-" instead of single "m".
166 This is to avoid confiliction of program names included in the other
170 * Changes in the m17n library 1.1.0
172 ** The "configure" script now detects Fontconfig, Xft2, and GD
175 If Fontconfig library is found, the library find local font files
176 (that are to be handled by the Freetype library) by fontconfig, and if
177 Xft2 library is also found, draw text by Xft.
179 ** Mdevice (new symbol) is recoginized as a key in the argument PLIST
182 The value must be Mx (new symbol), Mgd (new symbol), or Mnil. See the
183 documentation of mframe () for more detail.
185 ** MDrawControl has a new member `anti_alias'.
187 If MDrawControl->anti_alias is nonzero, try to draw anti-aliased text
188 if local fonts are used for that text via Freetype. If Xft2 library
189 can be used, the anti-alias processing is done by Xft2's drawing
190 routine. Otherwise, the m17n library itself does it by assumming that
191 the background color is `background' property of a face.
193 ** Modification of face is now automatically refelected to the next
196 So, for instance, an application can change the default face of a
197 frame after the frame is created. The sample program "medit" utilize
200 ** New function mfontset_lookup () reports contents of a fontset.
202 ** New function mplist_deseriaze () parses an M-Text and generates a
205 ** The functions mfont_name () and mfont_from_name () are now obsolete
206 (still kept for backward compatibility). Use mfont_parse_name () and
207 mfont_unparse_name () instead.
209 ** The sample program "mdump" generates PNG image file instead of PBM.
211 It now runs only when the m17n library is configured with the Freetype
212 library and the GD library.
