There is a disproportion between what's written on DownloadInfo page and how http://boinc.berkeley.edu/download_all.php really behaves.
For instance the parameter version=x seems to be completely ignored, both min_version=x and max_version=x compare the parameter x with version numbers as strings, not as a set of integers, separated with commas (the way Boinc versions are really numbered).
This way it is not possible to filter the displayed/suppressed version correctly (read: as intended) (because the string comparison is causing such irrational nummeric sequence like 0, 1, 10, 11, ..., 19, 2, 20, 21, ..., 3, 4, 5, 6, 7, 8, 9). Because of this, queries like download_all.php?max_version=5.7.99 or download_all.php?min_version=5.8&dev=1 produce absolutely unexpected results.
