I don't see that here (the HTTP directory shows the new date). But it doesn't matter -- the PDF file hasn't changed for the last three weeks.On the download page the help file says it is dated April 10 version for the latest build, but the file when down loaded seems to be the March 29th version.
I rechecked the web site and the pdf file has an April date. You're probably retrieving a cached copy from somewhere; try downloading it again.It's in the copyright notices. The chn file says April 7 and the pdf down load shows the March date. The help for ffind shows the /8 switch in the chn file but pdf doesn't show the new option. Release notes state that the help files have been updated for build 60
