What's new in v3?

I recommend you read http://www.codeigniter.com/user_guide/in...e_300.html carefully.

The major differences between v2 and v3 that I think are:

• The License (Now MIT)
  
• Classes file names convention (Start with a capital letter)
  
• Session library (Completely re-written. The default is file session now)
  
• New Encryption library
  
• Usage of XSS filtering (Input filtering is wrong)
  
• Active Record is renamed to Query Builder
  
• Composer auto-loader
