I was testing out Rails 3.2.8 against ruby-head (2.0) and found that sprockets was not working as expected (documented in sstephenson/sprockets#352)
After closer inspection, seems like actionpack is locked in sprockets 2.1.3 while sprockets has fixed a lot of issues since then (currently version 2.5.0)
It will be great if Rails 3.2.8 could bump its dependency at least to sprockets 2.4.x where this issue with ruby-head was solved.
Thank you! ❤️ ❤️ ❤️
