Queries on varieties of update

1. See the bottom of http://sparkle.andymatuschak.org/documentation/pmwiki.php/Documentation/PublishingAnUpdate

2. No. You can do this yourself though by implementing the delegate method:
- (SUAppcastItem *)bestValidUpdateInAppcast:(SUAppcast *)appcast forUpdater:(SUUpdater *)bundle; (see SUUpdater.h)

3. See #2. Return nil if no update is valid.

Some pointers for how do I detect the 3rd party application versions, like for example the installation should be valid only when my application uses Safari 3.3 not on Safari 3.2 .

Thanks in advance

Sorry, but that really doesn't fall under my purview of support. Check the docs for NSBundle.

OS version comparison need to be validate:
I referred to the bottom of http://sparkle.andymatuschak.org/documentation/pmwiki.php/Documentation/PublishingAnUpdate

So in my appcast.xml if I put sparkle:minimumSystemVersion "10.6.5" then the update won't happen in 10.5.5 ?But the behavior what I see is not happening in that way.It gets update as well in 10.5.5.Is there any source change is required for the same?
Do I need to do any additional checks.

Secondly Can I modify the log statements like for example when the update is already done and if I forcibly try to update it should say the "application is up to date" also when the OS version mismatch is there it should say similar statments.

Thanks in advance

Post the URL of your appcast here; I'll take a look.

You can't modify Sparkle's responses without changing the strings files, but it already does what you ask.

Hi,
Below is the appcast file.
I have kept the sparkle:minimumSystemVersion="10.6.6" but my OS is of 10.5.5.So I am expecting update should fail once I try to download the file from my app.But it gets downloaded and the app gets launched as well.
