Is there a change to the SDLXLIFF format in Studio 2017 which stops tools like ChangeTracker or SDLXLIFF Compare working?

Question

Hi everyone, 
 Occasionally I need to create a report of changes made by reviewers to translator's work. I've used ChangeTracker or SDLXLIFF Compare in the past but since upgrading to Studio 2017, neither tool works. I am absolutely certain that there are changes contained in the files I am comparing as I have confirmed this with a diff tool. Interestingly, the updated online version of ChangeTracker TQAuditor is able to compare the files, which makes me wonder if the underlying sdlxliff structure has changed and the other tools I have used have not been updated. 
 Does anybody know of a working app which can be used in Studio 2017 to compare changes between files or an external application? Unfortunately I can't use TQAuditor for some confidential projects. 
 Many thanks, 
 Daniel

Hello Daniel, 
I have seen the same behaviour and I think the reason is filetype with HTML embedded content. Whereas ChangeTracker reports no changes, SDLXLIFF Compare sais: An item with the same key has already been added.

Hi Ladislav, That makes sense. All of the projects I have been working on recently use embedded content. And those are the exact errors I get. Thank you for confirming this. At least in theory I should be able to use the tools for other projects which don't use that file type. 
 Many thanks, 
 Daniel
