Hot off the presses! GoldMine 6.70.70226 has been released. This should fix the problem with disapearing history and provide Internet Explorer 7.0 compatibility.
I haven't seen an announcement from FRS but it's now available on the Partner Site, which, usually, means that it will be in General Availibility and available via Net Update very soon...
I have not had a chance to test. I'd let this sit for a week so someone else can find any new bugs and if the coast is clear and you're entitled to the update then upgrade.
One change that came up in testing was that Web Import now requires a password. If you're using GoldMine's Web Import be sure you change your web import setup before upgrading!
