v0.7.0

Added

• Support for new TEAL 3 features:
  • Bit/byte manipulation and new transaction and global fields (#50).
  • Dynamic Gtxn indexes (#53).
  • MinBalance expression (#54).
  • Documentation for new features (#55).
• Added the ability to specify the TEAL version target when using compileTeal (#45).
• Added ScratchVar, an interface for storing and loading values from scratch space (#33).
• Added a warning when scratch slots are loaded before anything has been stored (#47).

Changed

• Rewrote internal code generation to produce smaller programs and make future optimization easier
  (#26). Programs compiled with this version will likely
  produce different TEAL code than previous versions, but their functionality will be the same.

v0.6.2

Fixed

• Corrected documentation and examples that incorrectly used the Txn.accounts array (#42).
• Fixed improper base32 validation and allow the use of padding (#34 and #37).

• An application deployment example, vote_deploy.py.

Fixed
