- More C90 (ANSI C) compliance.
  (Thanks Peter Moulder for the patch)
- Prevent some compiling conflicts with other sources.
  (Thanks Peter Moulder for the patch)
- Fix miscellaneous compiler warnings.
- Prevent trimming on extremely long dictionary path names.

0.2.11 (2018-04-23)
======
- Detect iconv() error more correctly in trietool.
  (Thanks Daniel Macks for the report on Issue #3)
- Clarify package description that search time is O(m), where m is
  key length, not O(1), while still claiming that it's independent
  of database size.
  (Thanks @flackbash for the report on Issue #4)
- Fix trie_state_get_data() on a prefix key.
  (Thanks Filip Pytloun from the pytries project for the initial patch)
- Fix reported segfault on full-range alpha map.
  (Thanks Xiao Wang for the report on Issue #6,
  and @nevermatch for the analysis.)

0.2.10 (2015-10-20)
======
- Correctly check doxygen version on configure.
  (Thanks Petr Gajdos for the patch.)
- Optimization on AlphaMap mapping.
  (contributing to 0.2% less run time for LibThai word breaking)

0.2.9 (2015-05-03)
=====
- Fix binary file opening on Windows
  (Thanks phongphan.p for the report and initial patch.)
- Fix infinite loop on empty trie iteration.
  (Thanks Sergei Lebedev for the report and analysis.)
- Micro-optimization with LIKELY/UNLIKELY hints.
  (contributing to 4.76% faster dictionary loading, 1.95% faster
  word breaking for LibThai)
- Improved error handling
- 'trietool-0.2' utility is renamed to just 'trietool'
- Improved documentation
  (Thanks edgehogapp for the suggestion.)
- No timestamp on Doxygen-generated doc
  (Thanks Debian Reproducible)

0.2.8 (2014-01-10)
=====
- Fix compiler warnings in test suites.
- Fix edge-case error on alphabet set of size 255.
  (Thanks Naoki Youshinaga for the report, test case, and analysis.)
- Fail trie operations on non-alphabet inputs, rather than silently allowing
  them to sneak in as false keys.
  (Thanks Naoki Youshinaga for the suggestion.)
- Improved documentation.

0.2.7.1 (2013-10-22)
=======
- Bump library versioning to reflect API addition.
  (Change missing in previous release)

=====
- Fix portability issue with non-GCC compilers.
  [Thanks Gabi Daver for the report and fix (via Mikhail Korobov).]
- Fix compiler warnings.
- New utility API for comparing AlphaChar strings.
- Add test suites.
- Update doxygen doc generation.

0.2.6 (2013-01-23)
=====
- New API trie_state_walkable_chars() for breadth-first traversal.
- New class TrieIterator for callback-free enumeration.
- Improved performance on key enumeration.
- Improved AlphaMap range merging.
- Bug fixes.

0.2.5 (2011-11-04)
=====

0.2.4 (2010-06-30)
=====

  This is useful for preventing race condition in multi-thread applications.
  [Suggestion from Dan Searle]
- Add trie_fread() and trie_fwrite() APIs for reading/writing trie data in
  an open file, allowing trie to be embeded as part of a bigger file.
  [Suggestion from NIIBE Yutaka]
