Agile Web Solutions as updated 1Password so it now works with Safari 3.1. Safari 3.1 and improved Palm support seem to be the big changes in this release. But there’s a longer list of enhancements, changes and bug fixes in the version history.
The update is available through 1Password’s internal software update feature or as a direct download.
I installed through software update without a problem on my Intel Macs running OS X 10.5.2. I visited a few websites with Safari 3.1 and didn’t have any problems. No reboot is needed but browsers do have to be restarted after the update.
Having to get an update to work with a new version of Safari highlights the main problem with input managers like 1Password. While it may look like the Safari update breaks 1Password it’s more a case of 1Password using unsupported hacks to accomplish their task since there’s no direct API.
