0.3.0

Changed

• Deprecated dynamic bonding curve. deploy_token and claim_creator_fees are now
  coming-soon stubs (registered, take no arguments, return a coming-soon notice) pending MomoSwap
  launchpad support. Dropped the bonding-curve implementation, the dynamic_bonding_curve IDL, and
  the cookieboxHosted / bondingProgress fields from get_token_info.
