71 the potential for it to be used interactively through a pipe.
72 <li>Removed debug output in <samp><span class="command">aspell munch-list</span></samp>.
73 <li>Other minor updates and bug fixes.

84 <li>Large number of bug fixes.
87 <h3 class="heading">Changes from 0.60.3 to 0.60.4 (October 19, 2005)</h3>
90 <li>Fixed a bug that caused Aspell to crash when checking certain Russian

107 suggestions when soundslike lookup was not used.
108 <li>Made a minor, yet significant, optimization to the suggestion code.
109 This sped things up by an order of magnitude in some cases.
110 <li>Avoid using the slow ngram scan except when the <samp><span class="option">sug-mode</span></samp> is
111 `<samp><span class="samp">slow</span></samp>' or `<samp><span class="samp">bad-speller</span></samp>'.

159 <li>Other miscellaneous manual changes such as updating the To Do and Authors
163 <h3 class="heading">Changes from 0.50.5 to 0.60 (August 27, 2004)</h3>
166 <li>Added support for Affix Compression. Affix compression stores the root
167 word and then a list of prefixes and suffixes that the word can take,
168 and thus saves a lot of space. The codebase comes from MySpell found in
169 OpenOffice. It uses the same affix file that OpenOffice (and Mozilla)
170 use. Affix compression will even work with soundslike lookup to a
172 <li>Added support for accepting all input and printing all output in UTF-8
173 or some other encoding different from the one Aspell uses. This
174 includes support for Unicode normalization. Aspell can now support any
175 language with no more than 210 distinct characters, including different
176 capitalizations and accents, <em>even if</em> there is not an existing
177 8-bit encoding that supports the language.
178 <li>Added support for loadable filters and customizable filter modes thanks
179 to Christoph Hintermüller.
180 <li>Enhanced SGML filter to also support skipping sgml tags such as "script"
181 blocks thanks to Tom Snyder.
182 <li>Added gettext support thanks to Sergey Poznyakoff
183 <li>Reworked the compiled dictionary format. Compiled dictionaries now take
184 up less space (less than 80% for the English language) and
185 creating them is significantly faster (over 4 times for the
187 <li>Reworked suggestion code. It is significantly faster when dealing with
188 short words (up to 10 times). Also added support for MySpell
189 Replacement Tables and n-gram lookup. In addition, added basic support
191 <li>Manual has has been converted to texinfo format thanks to the work of
193 <li>Reworked the build system so that a single Makefile is used for most
195 <li>All data, by default, is now included in
196 <samp><var>libdir</var><span class="file">/aspell-0.60</span></samp>. Also added a built time option to
197 increment the major version number of the shared library. This should
198 allow both Aspell version 0.50 and 0.60 to coexist. The major version
199 number is <em>not</em> incremented by default as Aspell 0.60 is binary
200 compatible with Aspell 0.50. See <a href="Binary-Compatibility.html#Binary-Compatibility">Binary Compatibility</a>.
201 <li>The code to handle dictionaries has been rewritten. Because of this
202 support for the dictionary option <samp><span class="option">strip-accents</span></samp> has been
203 removed. In addition the <samp><span class="option">ignore-accents</span></samp> option is currently
205 <li>Lots of other minor changes due to massive overhaul of the source code.
209 <h3 class="heading">Changes from 0.50.4.1 to 0.50.5 (Feb 10, 2004)</h3>
212 <li>Reworked url filter which fixed several bugs and now accepts
213 "bla.bla/kdkdl" as a url.
214 <li>Fixed bug in which the url filter was coming before all other filters
215 when it was supposed to come after. This solved a number of problems
216 where the url filter was interfering with other filters.
217 <li>Small bug fix in SGML filter.
218 <li>Added code page charsets, ie cp125?.dat.
219 <li>Added natural (split) keyboard data file as "split.kbd"
220 <li>Compile fixes for the upcoming Gcc 3.4
221 <li>Removed Solaris link hack as it was causing more problems than it
223 <li>Compile fixes for Sun WorkShop 6 compiler, but there may still be some
224 problems, especially with linking.
225 <li>Included patch to help compile with Microsoft Visual C++ 6.
226 <li>Minor manual fixes.
227 <li>Updated the TODO section to reflect the current progress with the next
228 major version of Aspell (0.51).
229 <li>Updated to Autoconf 2.59, Automake 1.82, and Libtool 1.5.2.
232 <h3 class="heading">Changes from 0.50.4 to 0.50.4.1 (Oct 11, 2003)</h3>
235 <li>Fixed major bug in pipe mode which caused the last character to be
236 chopped off words before they were stored.

254 <li>Complain instead of doing nothing or aborting for unimplemented
255 functions in Aspell utility.
257 <li>Portability bug fixes.
259 <li>Upgraded to Autoconf 2.57, Automake 1.7.7, Libtool 1.5 (no longer use
260 CVS version of libtool).
263 <h3 class="heading">Changes from 0.50.2 to 0.50.3 (Nov 23, 2002)</h3>
266 <li>Hopefully fixed the Ispell alignment error problem when Aspell is used
269 <li>Fixed a problem with personal dictionaries on NFS mounted home
272 <li>Compiled libaspell-common directory into libaspell for now to avoid

364 <li>Compile fixes so that it will compile with Gcc 3.0.
366 <li>Compile fixed which should allow Aspell to compile with Egcs 1.1. I
367 have not been able to actually test it though. Please let me know at

444 <li>Some major modifications to make Aspell more C++ compliant in order to
445 get Aspell to compile under the upcoming Gcc 3.0 compiler. This
446 included only using STL features found in the standard version of C++.
447 (Which means Aspell will no longer require using the SGI version of
448 the STL) This should also make compiling C++ under non-gcc compilers a
449 lot simpler. Please note that Aspell still has some problems with the
450 upcoming Gcc 3.0 compiler.

513 of the special <strong>multi</strong> lists.
515 <li>Added a large number of hacker related words and some other slang
516 terms to the medium size word list.
518 <li>Added an <strong>ispell</strong> and <strong>spell</strong> compatibility script for
519 systems which don't have Ispell installed. They are located in the
520 scripts/ directory and are not installed by default.
524 <li>Added a note on not using GNU Make on Solaris.
527 <h3 class="heading">Changes from .32 to .32.1 (August 5, 2000)</h3>

569 <li>Fixed a bug where Aspell would not create a complete dictionary file
570 on some platforms when the data is 8-bit.

638 when compiled with gcc 2.95 or higher. This involved reworking the
639 Exception heritage to get around a bug in gcc 2.95.
641 <li>Added a few more commands to the list of default commands the TeX
644 <li>Aspell will now check if a word only contains valid characters before
645 adding it to any dictionaries. This might mean that you have to
646 manually delete a few words from your personal word list.
648 <li>Added option to ignore case when checking a document.
650 <li>Adjusted the parameters of the <strong>normal</strong> suggest mode to so that
651 significantly less far fetched results are returned in cases such as
652 tomatoe, which went from 100 suggestions down to 32, at the expense of
653 getting slightly lower results (less than 1%),
655 <li>Improved the edit distance algorithm for slightly faster results.
657 <li>Removed the `<samp><span class="samp">$$m</span></samp>' command in pipe mode, you should now use
658 `<samp><span class="samp">$$cs mode,</span><var>mode</var></samp>' to set the mode and <strong>$$cr mode</strong> to
659 find out the current mode.
661 <li>Reworked parts of Aspell to use Pspell services to avoid duplicating code.
663 <li>Added a module for the newly released Pspell. It will get installed
664 with the rest of Aspell.
666 <li>Miscellaneous other bug fixes.
669 <h3 class="heading">Changes from .29 to .29.1 (Feb 18, 2000)</h3>
672 <li>Improved the TeX filter so that it will accept '@' at the beginning
673 of a command name and ignored trailing '*'s. It also now has better
674 defaults for which parameters to skip.
676 <li>Reworked the main dictionary so that it can be memory mapped in. This
677 decreases startup time and allows multiple Aspell processes to use the
678 same memory for the main word list. This also also made Aspell 64 bit
679 clean so that it should work on an alpha now.
681 <li>Fix so that Aspell could compile on platforms that gnu is not yet
684 <li>Fixed issue with flock so it would compile on FreeBSD.
686 <li>Minor changes in the code to make it more C++ compliant although I am
687 sure there will still be problems when using some other compiler other
690 <li>Added some comments to the header files to better document a few of
694 <h3 class="heading">Changes from .28.3 to .29 (Feb 6, 2000)</h3>
697 <li>Fixed a bug in the pipe mode with lines that start with
698 `<samp><span class="samp">^$$</span></samp>'.
700 <li>Added support for ignoring all words less than or equal to a specified length
702 <li>New soundslike code based thanks to the contribution of Björn Jacke.
703 It now gets all of its data from a table making it easier for other
704 people to add soundslike code for their native language. He also
705 converted the metaphone algorithm to table form, eliminating the need
706 for the old metaphone code.
708 <li>Major redesign of the suggestion code for better results.
710 <li>Changed the format of the personal word lists. In most cases it
711 should be converted automatically.
713 <li>Changed the format of the main word list.
715 <li>Name space cleanup for more consistent naming. I now use name spaces
716 which means that gcc 2.8.* and egcs 1.0.* will no longer cut it.
718 <li>Used file locks when reading and saving the personal dictionaries so
719 that it truly multiprocesses safely.
721 <li>Added rudimentary filter support.
723 <li>Reworked the configuration system once again. However, the changes to
724 the end user who does not directly use my library should be minimal.
726 <li>Rewrote my code that handles parsing command line parameters so that
727 it no longer used popt as it was causing too many problems and didn't
728 integrate well with my new configuration system.
730 <li>Fixed pipe mode so that it will properly ignore lines starting with
731 '~' for better Ispell compatibility.
733 <li>Aspell now has a new home page at
734 <a href="http://aspell.sourceforge.net/">http://aspell.sourceforge.net/</a>. Please make note of the new
737 <li>Miscellaneous manual fixes and clarifications.

743 <li>Fixed a bug that caused Aspell to crash when spell checking words over
746 <li>Reworked <strong>aspell check</strong> so that
748 <li>You no longer have to hit enter when making a choice.
750 <li>It will now overwrite the original file instead of creating a new
751 file. An optional backup can be made by using the -b option.
754 <li>Fixed a few bugs in data.cc.
757 <h3 class="heading">Changes from .28.2 to .28.2.1 (Aug 25, 1999)</h3>

768 <li>Fixed a bunch of bugs in the language and configuration classes.
770 <li>Minor changes in the code so that it could compile with the new gcc
773 <li>Changed the output of <code>dump config</code> so that default values are
774 given the value <code><default></code>. This means that the output can
775 be used to create a configuration file.
777 <li>Added notes on using Aspell with VIM.
780 <h3 class="heading">Changes from .28 to .28.1 (July 27, 1999)</h3>
783 <li>Removed some debug output
785 <li>Changed notes on compiling with gcc 2.8.* as I managed to get it to
786 compile on my school account
788 <li>Avoided including <strong>stdexcept</strong> in <samp><span class="file">const_string.hh</span></samp> so that
789 I could get Aspell to compile on my school account with gcc 2.8.1.
792 <h3 class="heading">Changes from .27.2 to .28 (July 25, 1999)</h3>
795 Provided an iterator for the replacement classes.
797 <li>Added support for dumping and creating and merging the personal and
798 replacement word lists.
800 <li>Changed the Aspell utility command line a bit, it now used popt.
802 <li>Totally reworked Aspell configuration system. Now Aspell could get
803 configuration from any of 5 sources: the command line, the environment
804 variable <samp><span class="env">ASPELL_CONF</span></samp>, the personal configuration file, the
805 global configuration file, and finally the compiled-in defaults.
807 <li>Totally reworked the language class in preparation for my new language
808 code. See <a href="http://aspell.sourceforge.net/international/">http://aspell.sourceforge.net/international/</a> for more
809 information of what I have in store.
811 <li>Added some options to the configure script: –enable-dict-dir=DIR,

814 <li>Removed some old header files.
816 <li>Reorganized the directory structure a bit

847 <li>Updated the section on using Aspell with egcs to it. It was now more
848 clear why the patch was necessary.
851 <h3 class="heading">Changes from .26.2 to .27 (Feb 22, 1999)</h3>
854 <li>Totally reworked the C++ library which means you may need to change
855 some things in your code.
857 <li>Added support for detachable and multiple personal dictionaries in the
860 <li>The C++ class library now throws exceptions.
862 <li>Reworked Aspell ability to learn from users misspellings a bit so that

904 <li>Fixed a bug that caused duplicate items to be displayed in the
905 suggestion list for good. (If it still does it please send me email.)
907 <li>Added the ability for Aspell to learn form the users misspellings.
909 <li>Library Interface changes. Still more to come <small class="dots">...</small>.

928 <li>Fixed the version number so that Aspell reports the correct version
931 <li>Changed the note on gcc 2.7.2 compilers to make it clear that only the
932 C++ compiler cannot be gcc 2.7.2, it is OK if the C compiler is gcc
935 <li>Updated the TODO list and reorganized it a bit.
937 <li>Fixed the directory so that all the documentation will get installed
938 in <tt>${prefix}/doc/aspell</tt> instead of half of it in
939 <tt>${prefix}/doc/aspell</tt> and half of it in
940 <tt>${prefix}/doc/kspell</tt>.
943 <h3 class="heading">Changes from .24 to .25 (Nov 23, 1998)</h3>
946 <li>Total rework of how the main word list is stored. Start up time

955 <li>Changed the scoring method to produce slightly better results with
956 words like the vs. teh. And other simpler misspellings where two
959 <li>Fixed the very unpredictable behavior of the `<samp><span class="samp">*</span></samp>', `<samp><span class="samp">&</span></samp>',

972 <em>fone</em> vs <em>phone</em> and other words that have a spelling that
973 doesn't directly relate to how the word sounds by using the phoneme
974 equivalent of the word in the scoring of it.
976 <li>Added the <code>to_phoneme</code> and <code>have_phoneme</code> methods to the
977 <code>SC_Language</code> class.
979 <li>Added the <code>to_phoneme</code> method to the <code>aspell</code> class.
981 <li>Added the framework for being able to learn from the users
982 misspelling. Right now it just keeps a log of replacements.
984 <li>Redid <samp><span class="file">stl_rope-30.diff</span></samp>. For some reason the version of patch
985 on my system refused it.
987 <li>Rewrite of the “<em>Using as a replacement for Ispell</em>” section

1020 cut the number of words returned for these roughly in half.
1022 <li>Expanded the word list to also include <strong>american.0</strong> and
1023 <strong>american.1</strong> from the Ispell distribution. It now includes
1024 <strong>english.0</strong>, <strong>english.1</strong>, <strong>american.0</strong> and

1034 <h3 class="heading">Changes from .22 to .22.1 (Oct 27, 1998)</h3>
1037 <li>Minor bug fixes. I was deleting arrays with delete rather than
1038 delete[]. I was suprised that this had not created a problem.
1040 <li>Added a simple test program to test for a memory leak present on some
1041 systems. (Only debian slink at the moment.) See the file
1042 memleak-test.cc for more info.
1045 <h3 class="heading">Changes from .21 to .22 (Oct 26, 1998)</h3>
1048 <li>Major redesign of the scoring method. It now uses absolute distances
1049 rather than relative scores for more consistent results. See
1050 <samp><span class="file">suggest.cc</span></samp> for more info.
1052 <li>Suggest code rewritten in several places, however the core process
1055 <li>The <code>suggest_ultra</code> method temporarily does nothing. It should
1056 be working again by the next release.

1062 <li>Added documentation for aspell::Error
1065 Changed the library name from <code>libspell</code> to <code>libaspell</code>. It

1077 <li>Added the <strong>score</strong> method to <code>aspell</code>.
1079 <li>Changed the scoring method to deal with word when the user uses "f" in
1080 place of "ph" a lot better.
1083 <h3 class="heading">Changes from .11 to .20 (Oct 10, 1998)</h3>
1086 <li><em>Name change</em>. Everything that was Kspell is now Aspell. Sorry,
