What are the five biggest events in the charter school world over the past few months?

Wow, a lot has been happening. I can't even think of the most important events. Here is the beginning of my list. Can you help me fill it out?

1. Georgia striking down its state charter school authorizer law.
2. Tennessee lifting its cap on charter schools.
3. North Carolina lifting its cap on charter schools.
4. Maine passing a charter school law.

I thought I might be able to get to ten if I really tried, but after those four it's tough to prioritize.

Feel free to comment. Thanks.
