I'm pleased to announce the release of LanguageTool 3.1. As usual, it is available for download at https://www.languagetool.org.
* Many updates for the error detection rules for English, French, German, Japanese, Polish, Portuguese, Russian, and Ukrainian
* Bug fixes
* Java API: removed deprecated methods; cleanups
Please see http://www.languagetool.org/download/CHANGES.md for a complete list of changes.
If the update from the extension manager in LibreOffice/OpenOffice fails for you, please uninstall the old version, restart, and then install the new version.
