Please, notice that shortly after 2.2e was published (with build number 153), 2.2e build 154 was uploaded, fixing a couple of nasty aged bugs.
My advice is, of course, to update.
This is to stress the subtle difference, having both releases the same name.
I did not delete any release.
Those files were just not there anymore.
I was uploading files with same filenames, because I thought SF was managing different releases in different directories.
I have a poor internet connection. I will upload files soon, from another computer. In the while you can reach files at http://www.rejetto.com/hfs
