    Localized Settings

    Two Writer-specific settings that should have localized values did not work exactly as intended in the past:

    • Tools ▸ Options ▸ Writer ▸ General ▸ Settings ▸ Tab stops should default to 7.4 mm for Chinese (locale “zh-CN”) and to 12.5 mm for all other locales.
    • Tools ▸ Options ▸ Writer ▸ AutoCaption ▸ Caption Order should default to “Numbering first” for Hungarian (locale “hu”) and to “Category first” for all other locales.

    This has been fixed now (c7ab472b47023c94c06de9e3479a2e0271084dfc, 552bebc85d907748dcd72b7978a00a3eee7c4f34), but you may still see unexpected values if you either changed these settings manually in the past, or even if you merely keep using a pre-existing user installation. In either case, please check whether these settings have appropriate values now for you, and change them if necessary in the Tools ▸ Options dialog. (Stephan Bergmann)
