Oh, we are so close.
For those unaware, a release candidate represents the version of the application that we think is going to wind up being the final release, so in a week or two you can expect the final version of OmniGraffle 5 to be in the spots traditionally held by versions 4, 3, 2, and so forth.
Of course, we're a bit on the cautious side as well, hence the appending of the number 1 after the words "release candidate".
Quite a few bug fixes and crashes addressed in this release, plus final fit and finish to the localizations.
A very interesting point to bring up:
This release does not have an internal license key as the prior beta releases did, OmniGraffle 5 will operate without a license key for two weeks, so fret not - this is also an important bit of testing going on.
You can download the release candidate from the
beta page, and read copious release notes
