0.19 brings some breaking changes, which I came to know after reading this blog post. So all of you Elm experts, which version would you recommend for someone just starting to learn Elm?
Programming Elm (book) is updated for Elm
0.19, but all other learning resources available target version
0.18. There are available some very good learning resources for Elm
0.18, like Pragmatic Studio’s course
Building Web Apps with Elm, KnowThen’s course
Elm beyond the basics etc, but the amount of breaking changes show that learning Elm 0.18 is a wasted effort, because later one has to unlearn everything deprecated.
