  • Fixed missing "l" in "Cyrillic"
  • History:
  • Removed "Wrap words" checkbox (the history_wrap_words option in settings.cfg is still available)
  • Recognized text is now immediately added to the history file to minimize possible data loss in case of abnormal program termination
  • Font size is now taken from system settings. This also fixes zooming text with Control + mouse wheel
  • HTML export:

  • CSS: Reduced left text margin from 2 to 1 em and added 1 em right margin
  • "Export history" file dialog now uses "History" as the default file name instead of leaving it empty

  • Default history export path is now the user's home directory instead of the directory of the executable
  • "Run executable" no longer opens Explorer if the path is empty

  • ocr_dump_debug_image was replaced by the DPSO_DUMP_DEBUG_IMAGE environment variable
  • ui_native_file_dialogs
  • Leading and trailing double quotes are no longer treated especially; if you need to preserve leading and trailing spaces, wrap the value in instead of double quotes. This change is not backward compatible with version 1.0, but in practice it will only affect the action_copy_to_clipboard_text_separator option.
