Features

• The library can now be used as a Java 9 module. Thanks to @Marcono1234 for helping with the implementation. (#120, #138)
• The new method LanguageDetectorBuilder.withLowAccuracyMode() has been introduced. By activating it, detection accuracy for short text is reduced in favor of a smaller memory footprint and faster detection performance. (#136)

Improvements

• The memory footprint has been reduced significantly by applying several internal optimizations. Thanks to @Marcono1234, @fvasco and @sigpwned for their help. (#101, #127)
• Several language model files have become obsolete and could be deleted without decreasing detection accuracy. This results in a smaller memory footprint and a 36% smaller jar file.

Bug Fixes

• A bug in the rule engine has been fixed that caused incorrect language detection for certain texts. Thanks to @bdecarne who has found it.

Other changes

• Due to a refactoring of how the internal thread pool works, the method LanguageDetector.destroy() has been deprecated in favor of the newly introduced method LanguageDetector.unloadLanguageModels().
