Crystal 0.7.0 released!

Crystal 0.7.0 has been released!

This is a huge, non-backwards compatible release that introduces two big features:

This release also contains numerous bug fixes, performance improvements and enhacements.

Please note that this is an experimental release: the change to non-blocking IO probably breaks some programs out there. We need your help to continue building this API, fix what’s not working and add what’s missing. But we strongly believe this is the direction we want to follow, as programming with spawn and channels is very easy, intuitive and efficient.

An explanation of these two features will come soon, together with documentation. But, basically, non-blocking IO, lightweight processes and channels work in a very similar way to how Go works. And Iterators work in a similar way to Ruby’s Enumerator, at least semantically (internally they are implemented in a different way).

Right now we are busy preparing a great talk for Curry On, we are thrilled to have been selected! You can see the detailed abstract of the talk here.

We would love to see you there!
