Fedora 13 Final TC1 is now available [1]. Please refer to the following pages for download links and testing instructions. Installation: https://fedoraproject.org/wiki/Test_Results:Current_Installation_Test Desktop: https://fedoraproject.org/wiki/Test_Results:Current_Desktop_Test Ideally, all Alpha, Beta, and Final priority test cases for installation [2] and desktop [3] should pass in order to meet the Final Release Criteria [4]. Help is available on #fedora-qa on irc.freenode.net [5], or on the test list [6].

Deltaisos also avoid downloading unchanged packages, but in addition save space for updated packages by using deltarpms instead of full RPMs. So a deltaiso between 2 given ISOs should always be more efficient (in terms of size) than any of the others in doing the conversion. Of course this is assuming that a single deltaiso between the two ISOs is available (as opposed to having to use several to go from A to B, then from B to C, etc. which is much less efficient). It's not feasible to produce a deltaiso between every pair of ISOs since the number grows quadratically. However, most testers download each TC/RC, so deltaisos just between successive TCs/RCs are usually enough. On the other hand, using deltarpms is expensive in terms of CPU. The tradeoffs between downloading deltarpms vs. full RPMs are exactly the same for using deltaisos vs. jigdo/rsync/zsync as they are for using yum-presto vs. not using it, so anyone who currently finds yum-presto of benefit should be better off using deltaisos vs. any of the other choices (even if they were available).

If rsync or zsync were available, you could get the same benefit as jigdo by concatenating your old ISO and all of your new cached RPMs together into a single large file, and running rsync/zsync on that to convert it into the new ISO. Unfortunately, rsync runs on the server, and turned out to be a resource hog, so it's not currently used for development images. Zsync runs on the client so shouldn't have this problem. Unfortunately, it's not available in Fedora yet. See http://kparal.wordpress.com/2009/09/01/zsync-transfer-large-files-efficie... https://bugzilla.redhat.com/show_bug.cgi?id=490140 https://bugzilla.redhat.com/show_bug.cgi?id=495310 Zsync would also be perfect for converting between different install disc sets (currently the DVD and the CD set) since the packages are exactly the same. It can also be used to efficiently convert from the first disc in either set to the netinst disc. So I'd certainly like to see it in Fedora.
