Looking for material to learn about Rails 4/5

Hi, I’m starting to work full-time with Ruby on Rails again. However, I haven’t used Rails during the past 3 years, thus my knowledge is a little bit out of date.

Do you have suggestions for material (books, websites, blogs, tutorials, …) to refresh my knowledge and learn about new concepts, e.g. pipelines, russian doll caching etc?

Best wishes
