该版本修正了一些bug，还包括以下三个方面的改进：
- The break on next button moved from the main toolbar to the panel
toolbar. Physically this is not a lot of distance but it allows the
button to “belong” to the panel.
- The break on next button icons now depend upon the panel, with a
system of badges. Thanks jabapyth!
- Locale updates for uk-UA, hy-AM, hu-HU, cs-CZ.
