I’ve updated Simple Event Attendance (SEATT WordPress plugin) to version 1.3.0. This brings bug fixes, and updates in line with the release of WordPress 4.3.1.
Firstly, an apology for taking so long to release another version – feel welcome to get in touch if you want to discuss changes you’ve made to your code in the interim. These are largely security changes, so it’s recommended that you update when you can. The database structure hasn’t changed, so you should experience no loss of data.
