According to the release notes, 1.7 adds the above-mentioned improvements to provide more opportunities for database compaction. I am on a three-client setup (Mac, Mac, iPhone), and am seeing unreasonable ZIP file numbers (650 and climbing) with OmniFocus 1.7.1 on both Macs.

Any suggestions for how to take advantage of the sync improvements?

As a general point of feedback, the current syncing implementation requires the user to be far too conscious of the sync implementation to avoid ballooning sync databases and sluggish performance. Any sync implementation that is unable to deal with the scenario of a user syncing each of the registered clients on a daily basis is, I suggest, broken by design.
