I am not sure how to proceed with an upgrade to 1.0:

According to the claydoh ppa
kmymoney2 - 1.0.0-0ubuntu1~jaunty5 is
available.

However my Synaptic Package Manager shows
20090719cvs-0ubuntu1~jaunty5 (jaunty) as the current version.

Using Force Version I could choose
kmymoney2 - 1.0.0-0ubuntu1~jaunty5

But I get a warning that
"The package manager always selects the most applicable version available. If you force a different version from the default one, errors in the dependency handling can occur."

Is that a warning I can safely ignore or is there some other issue?

Why doesn't the package just upgrade like previously?

The package has been temporarily held back while Clay works out some issues he found with the upgrade.
The fault lies with us, because there were some big changes at the last minute before release, and we didn't give the packagers enough time to work them out.

That's OK then, I just wondered if I had overlooked something.
Thanks for the information.
