v0.10.1

Fixed

• Fixed a bug which caused incorrect TEAL code to be produced for mutually recursive subroutines with different argument counts (#234)
• Minor docs updates (#211, #210, #229)

v0.10.0

Added

• Support for new TEAL 6 features:
  • Increase maximum TEAL version (#146)
  • New Gitxn expression, inner transaction group creation with InnerTxnBuilder.Next(), inner
    transaction array field setting, and allow using dynamic slot IDs with ImportScratchValue (#149)
  • New BytesSqrt expression (#163)
  • New Global fields opcode_budget, caller_app_id, and caller_app_address (#168)

Fixed

• Various documentation fixes (#140, #142, #191, #202, #207)
• Clearer error messages when non-PyTeal expressions are present (#151)

Changed

• WARNING: Due to code generation improvements, programs compiled with this version will likely
  produce different TEAL code than previous versions, but their functionality will be the same. Be
  aware that even small differences in generated TEAL code will change the address associated with
  escrow LogicSig contracts.
• Optimized constant assembly for small integers (#128)
• Generated TEAL code for subroutines is more human-readable (#148)

• Transaction field documentation now separates fields by transaction type (#204)
• Added documentation about how to generate the documentation (#205)

v0.9.1

Added

• Documentation for exponent operator (#134)
• Documentation for using Seq with lists (#135)

Fixed

• Fixed use of wildcard import in Pylance (#133)

v0.9.0

Added

• Support for new TEAL 5 features:
  • AppParam expressions (#107, #123)
  • New nonparticipation transaction field (#106)
  • Inner transactions, zero-element Seq expressions, dynamic transaction array access (#115)
  • Logs, dynamic LogicSig argument indexes, single-element NaryExprs, and creating Bytes from bytes and bytearray (#117)
  • Extract expressions (#118)
  • More efficient implementation of recursive subroutines in TEAL 5+ (#114)
• Add WideRatio, an expression which exposes mulw and divmodw (#121, #122)

Changed

• WARNING: Due to code generation improvements, programs compiled with this version will likely produce different TEAL code than previous versions, but their functionality will be the same. Be aware that even small differences in generated TEAL code will change the address associated with escrow LogicSig contracts.
• Some unnecessary branch conditions have been removed (#120)

v0.8.0

Added

• Support for new TEAL 4 features:
  • Basic ops (#67)
  • Byteslice arithmetic (#75)
  • Importing scratch slot values from previous app calls (#79, #83)
  • Direct reference support for applications/accounts/assets (#90)
  • While and For loops (#95)
  • Subroutines (#99)
• New logo (#88, #91)
• Added the assembleConstants option to compileTeal. When enabled, the compiler will assemble
  int and byte constants in the most efficient way to reduce program size (#57, #61, #66).
• Added an alternative syntax for constructing If statements (#77, #82).
• Align Seq with the rest of the API (#96).

Fixed

• Fixed NaryExpr.__str__ method (#102).

Changed

• WARNING: Due to code generation changes required to support TEAL 4 loops and subroutines,
  programs compiled with this version will likely produce different TEAL code than previous
  versions, but their functionality will be the same. Be aware that even small differences in
  generated TEAL code will change the address associated with escrow LogicSig contracts.
• Improved crypto cost docs (#81).
• Applied code formatter (#100).

v0.7.0

• 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.
