  • Fix-length file parsing fixed when metadata contains autofilling fields as last fields

  • SpreadsheetDataReader mapping dialog was not opening for corrupt style information in Excel files. (java.lang.IndexOutOfBoundsException fixed)
  • Fixed file operations paths: relative vs. absolute path for remote location – see attached issue for explanation
  • Function removeNonPrintable() no longer removes non-ASCII accented characters (e.g. chars ä, ö, etc.)
  • Fixed JSONReader: fields containing underscores were not populated in implicit mapping
  • HTML graph export – fixed performance and star ($out.0. = $in.0.) mapping redering
  • Removed limitation for "maximum cache size" in the lookup dialog
