Pyteal

Changed
* Improved Router clear state program generation. ([636](https://github.com/algorand/pyteal/pull/636))
* NOTE: a backwards incompatable change was imposed in this PR: previous Clear State Program (CSP) can be constructed in router by registering ABI methods or bare app calls, now one has to use `clear_state` argument in `Router.__init__` to construct the CSP.

Added
* Added frame pointer support for subroutine arguments, replacing the previous usage of scratch. ([562](https://github.com/algorand/pyteal/pull/562))
* Added frame pointer support for local ABI variables in subroutine. ([606](https://github.com/algorand/pyteal/pull/606))
* Added `frame_pointers` property in `OptimizeOptions` to optimize away scratch slots during subroutine calls. This defaults to frame pointer usage when not specified for AVM version 8+. ([613](https://github.com/algorand/pyteal/pull/613))

Fixed
* Allowing the `MethodCall` and `ExecuteMethodCall` to be passed `None` as app_id argument in the case of an app create transaction ([592](https://github.com/algorand/pyteal/pull/592))
* No longer accidentally include additional package folders in release ([610](https://github.com/algorand/pyteal/pull/610), [#614](https://github.com/algorand/pyteal/pull/614))
* Fixed mistakes in docs ([612](https://github.com/algorand/pyteal/pull/612), [#625](https://github.com/algorand/pyteal/pull/625), [#627](https://github.com/algorand/pyteal/pull/627))

Changed
* Introducing `AbstractVar` to abstract value access: store, load, and stack type. ([584](https://github.com/algorand/pyteal/pull/584))
* NOTE: a backwards incompatable change was imposed in this PR: previous ABI value's public member `stored_value` with type `ScratchVar`, is now changed to protected member `_stored_value` with type `AbstractVar`.
* Starting with program version 9, when `scratch_slots` flag isn't provided to `OptimizeOptions`, default to optimizing. For versions 8 and earlier the default is and remains to _not_ optimize. ([613](https://github.com/algorand/pyteal/pull/613))
* Replaced the usage of `typing.NamedTuple` with `dataclass` for `class OpType` in the **ir** package in order to avoid [a regression coming in Python 3.11.1](https://github.com/python/cpython/issues/100098). ([#615](https://github.com/algorand/pyteal/pull/615))
* Upgrade mypy to v0.991. ([618](https://github.com/algorand/pyteal/pull/618))
* Upgrade py-algorand-sdk to v2.0.0. ([626](https://github.com/algorand/pyteal/pull/626))

Added
* adding program page related ops ([412](https://github.com/algorand/pyteal/pull/412))
* Add Replace ([413](https://github.com/algorand/pyteal/pull/413))
* Add Block ([415](https://github.com/algorand/pyteal/pull/415))
* Add JsonRef ([417](https://github.com/algorand/pyteal/pull/417))
* Add Base64Decode ([418](https://github.com/algorand/pyteal/pull/418))
* Support Secp256r1 curve ([423](https://github.com/algorand/pyteal/pull/423))
* Add VrfVerify ([419](https://github.com/algorand/pyteal/pull/419))
* Add Sha3_256 ([425](https://github.com/algorand/pyteal/pull/425))
* Support FirstValidTime transaction field ([424](https://github.com/algorand/pyteal/pull/424))
* Add Ed25519Verify_Bare ([426](https://github.com/algorand/pyteal/pull/426))
* AVM Boxes Ops in Pyteal ([438](https://github.com/algorand/pyteal/pull/438))
* Support new AVM 8 account parameters ([555](https://github.com/algorand/pyteal/pull/555))

Changed
* Changes to avm8 docs ([546](https://github.com/algorand/pyteal/pull/546))

Added
* Added option to `OpUp` utility to allow specification of source for fees ([566](https://github.com/algorand/pyteal/pull/566))

Fixed
* Erroring on constructing an odd length hex string. ([539](https://github.com/algorand/pyteal/pull/539))
* Incorrect behavior when overriding a method name ([550](https://github.com/algorand/pyteal/pull/550))
* Add missing `abi.NamedTupleTypeSpec` equality override, such that equality holds only when `instance_class` and `value_type_specs` match. ([540](https://github.com/algorand/pyteal/pull/540))
* Prohibited instantiating `abi.NamedTuple` from inheriting subclasses of `abi.NamedTuple`, for fields in subclasses are not inherited. ([540](https://github.com/algorand/pyteal/pull/540))
* Fixed bug in app arg tupling and detupling when a Txn argument is present ([577](https://github.com/algorand/pyteal/pull/577))

Changed
* Subroutines that take ABI type of Transaction now allow any Transaction type to be passed. ([531](https://github.com/algorand/pyteal/pull/531))
* Relaxing exact type check in `InnerTxnFieldExpr.MethodCall` by applying `abi.type_spec_is_assignable_to`. ([561](https://github.com/algorand/pyteal/pull/561))

Fixed
* ABI methods without a docstring now have their arguments in the output Contract object. ([524](https://github.com/algorand/pyteal/pull/524))

Added

* ABI Methods will now parse the docstring for the method and set the description for any parameters that are described. ([518](https://github.com/algorand/pyteal/pull/518))
* Note: the docstring must adhere to one of google, rst, numpy , or epy formatting styles.

Fixed
* Subroutines annotated with a `TupleX` class are now invoked with an instance of that exact class, instead of the more general `Tuple` class ([519](https://github.com/algorand/pyteal/pull/519))
