I was just informed of the update to 1Password 7 Version 7.8.8.BETA-0 (70808000), and I installed it as usual. Also, as usual, the updater hung at the 'Validating...' stage, even though the app had been updated and would launch OK. I quit the installer, as I usually do! This isn't a big deal, but I hadn't seen it mentioned here, so I thought I should report it.
