I want to export from Lyx a document as a PDF file. Since my person I am sending the file to does not have Lyx I would like to send him the PDF file containing the changes I made since the last version of the document.

I know that pdflatex does not preserve the tracking changes as this is documented almost everywhere, however, the same sources say that using the ps2pdf method or the Dvipdfm method this information is preserved.

I tried both of them, but the PDF result is still clean without the tracking changes. It appears that I need to do at least one more thing to accomplish what I want. Any help will be appreciated. Thanks

OK. I dug a little more through the Lyx's menus and I found the answer.

The solution is to go the menu: Document-> Change Tracking -> Show changes in Output.

Also, worth to be mentioned is that it appears that this works for all 3 PDF export methods including pdflatex.

I am wondering then if this wiki document is wrong or obsolete?
