[graphviz-interest] graphviz-2.39.20150520.1950.tar.gz has been stealth-updated

Hello,

The file graphviz-2.39.20150520.1950.tar.gz on your server has been changed since it was uploaded -- not the contents of the files inside the archive, but their timestamps. The file was presumably first uploaded on 20150520. When I downloaded the file early on 20150523, some files in the archive were timestamped on 20150522. Downloading the file today, it contains files timestamped on 20150524. The changed timestamps cause the checksums of the tarball to change, which causes problems for anyone trying to use checksums to verify the file's integrity, as MacPorts does, as was reported here:

https://trac.macports.org/ticket/47902

I also note that this 20150520 tarball is the most recent available, though today is 20150530. You used to upload a tarball automatically every day. I assume you have changed your process so that you upload a tarball only when there have been changes in the repository, and that for a few days you had a bug in your procedure where you were rebuilding and uploading the tarball with new timestamps even though there had been no changes. Is that about right? You mentioned in this Graphviz bug report that you were going to change the frequency of the tarballs:

Has the process now been stabilized so that we can once again rely on the checksums of your files not changing after they are initially uploaded?

Thanks,
-Ryan
