18+* A Cabal `fast` flag was added to disable building with optimizations. This drastically speeds up compiling both aeson ***and*** libraries using aeson so it is recommended to enable it during development. With cabal-install you can `cabal install aeson -ffast` and with stack you can add a flag section to your stack.yaml:

1825* Added list specific members to `ToJSON` and `FromJSON` classes. In
1926 the same way `Read` and `Show` handle lists specifically. This
