PyTeal v0.7.0 Released

Hi everyone, PyTeal v0.7.0 has just been released.

This update contains an optimized code generator, support for expressions using scratch space, and a lot of new features from TEAL 3. The full changelog is here: Release v0.7.0 · algorand/pyteal · GitHub

Code using PyTeal v0.6.x should be fully compatible, but the compiled TEAL code may be different due to code generation changes.
