@stobrien89 Could you please take a look and merge this? 😄

Is quite a big blocker on all our Laravel projects 😞

Hi all, sorry for the delay. Working to get this reviewed and merged.

Was running into some security advisories on install with 6, 7 and 8. I checked Laravel's support matrix and think it would be reasonable to drop support for these versions given the length of their EOL status. 9 is recent enough to keep, IMO.

Seems right to me. Would it be a dumb idea to update to v3 on this?

If you're referring to this package, we'll definitely do a minor version bump. If there are deprecated patterns or other things in the codebase that need to be updated, we can come back and address those once we unblock the support for 13.

If you're referring to the SDK, I bumped the floor in composer.json to where we made changes to address 8.5 deprecation warnings and added support in our CI.
