MySQL Upgrade from 5.5 to 5.6. Running Perch 2.8.26. Concerns?

Hello!

My web host just announced they will be upgrading from MySQL 5.5 to 5.6 on April 20th. Is there any reason I should be concerned for my client's version of Perch or Perch in general? I can find no information about a maximum version of MySQL for Perch, just a minimum.

My client is on a tight upgrade schedule for budget reasons, and bringing Perch up-to-date to the current version wasn't planned until next month, but I will move the schedule up if there are concerns.

Full diagnostics below. (Some lines removed for privacy)
