• Issue #451 : Data paging was allowing the user to jump beyond the end of a stream whereby just the XML root elements were displayed. This is now fixed by adding a constraint to the page offset so that the user cannot jump beyond the last record. Because data paging assumes that segmented streams have a header and footer, text streams now include segments after a header and before a footer, even if neither are added, so that paging always works correctly regardless of the presence of a header or footer.

• Issue #461 : The stream attributes on the filter dialog were not sorted alphabetically, they now are.

• Issue #460 : In some instances error streams did not always have stream attributes added to them for fatal errors. This mainly occurred in instances where processing failed early on during pipeline creation. An error was recorded but stream attributes were not added to the meta data for the error stream. Processing now ensures that stream attributes are recorded for all error cases.

• Issue #442 : Remove 'Old Internal Statistics' folder, improve import exception handling

• Issue #457 : Add check to import to preventy duplicate root level entities
