Terraform 0.11 Support and Development Question

We currently have all our modules configured to use Terraform 0.11 and are planning on moving to 0.12. I just have a couple of questions in order to prioritise the upgrade,

  • Is Terraform 0.11 still supported and if so when will it be no longer supported?
  • When will the providers for 0.11 not be actively supported and updated?

I would like to know this information so that we can plan the way that we update our modules as we use versioning we can pick and choose which ones we update and when to update them. Also we can choose to create new modules from scratch for immutable infrastructure rather than upgrade the code.
