Conan migration guide to 2.0

Conan 2.0-alpha is already released, you can install the latest Conan Alpha version from PyPI doing:

$ pip install conan --pre

If you want to migrate to 2.0, there are several things you will need to change:

• The recipes have to be updated to be compatible with Conan 2.0. There are 2.0 features ported to Conan 1.X so you can get a compatible recipe with 2.0 using Conan 1.X.

• The conan commands have also changed, but there are no “compatible” commands introduced in Conan 1.X. We will review the more relevant changes.

• General changes not related to the recipes nor the Conan commands, “build profiles”, lowercase references… etc.
