Subject: [PATCH 02/88] NFT implementation WIP

- Add interface files for NFT contracts
- Rename CFANFTBase => CFAv1NFTBase
- Move shared functions from NFT contracts to CFAv1NFTBase
- Rename NFT contracts
- WIP ConstantInflowNFT
- Add NFT contracts to SuperToken storage
- Add tests for new storage
- Add new storage variable external view functions in ISuperToken.sol

Subject: [PATCH 03/88] NFT  contracts upgradability

- use OZ Upgradeable interface mainly for explicit semantics for developers
- add upgradability to CFAv1NFTBase with UUPSProxiable contract
- add proxiableUUID function in CFAOutflow/CFAInflowNFT's
- add updateCode function into CFAv1NFTBase

Subject: [PATCH 05/88] constant outflow nft tests

- added onlyConstantInflowNFT modifier
- added dev-forge in ethereum-contracts
- cfav1nft base abstract contract inherited by nft tests
  - does initialization
  - has some tests
  - holds logic which will be used by both tests
- constant outflow nft basic tests (no transfer)

Subject: [PATCH 10/88] fix tests w/ cfa integration

- remove cfa hook mock contracts
- remove cfa hook code from cfa (except for storage)
- fix up SuperfluidFrameworkDeployer (add cfa nft contract deploy + initialization)
- add deployment of cfa nft logic contracts in deploy-framework only in protocolReleaseVersion="test"
- add deployment of cfa nft proxy, initialization and attach to supertoken in deploy-super-token only in protocolReleaseVersion="test"
- try/catch expect event in ConstantFlowAgreementV1.behavior.ts due to test tooling issues...
- fix up cfav1 forwarder and supertokenv1library cfa tests

Subject: [PATCH 12/88] cfa integration tests super happy path

- test nft minted on flow create
- test nft emits metadataupdate on flow update
- test nft deleted on flow delete
- function renamed to follow consistent_Naming_Pattern
- add emitting address parameter to event asserts

Subject: [PATCH 14/88] comment review WIP

- renaming of IDA stuff
- change from _gap to _reserveN
- delete expect Transfer in behavior
- move integration tests to outflow NFT test file (removes duplication)
- add test_Revert_Create_Flow_Overflows_When_Timestamp_Greater_Than_Uint32_Max test
- fix up mocks

Subject: [PATCH 15/88] fix build and cleanup

- delete transfer code from constant inflow nft
- delete mint/burn code from constant outflow nft
- link nft deployer library in deploy-test-framework.js
- add foundry coverage to test-coverage script
- refactor FoundrySuperfluidTester slightly
- add missing test cases for 100% coverage

Subject: [PATCH 18/88] NFT proxy deployment

- add in the NFT proxy deployment in SuperTokenFactory
- add in missing events for NFT logic creation and nft proxy contract creation
- add a deployer superfluid NFT deployer library
- modify validateStorageLayout for SuperTokenFactory because of new slots for logic contracts
- add in missing assume in tests
- modify SuperTokenDeployer to leverage new SuperTokenFactory.deployNFTProxyContractsAndInitialize

Subject: [PATCH 31/88] cleanup continued

- interface cleanups
- cache cfaV1 in storage during initialization for CFAv1NFT contracts
- access control onCreate/Update/Delete hooks to only be called by CFAv1
- add tests to ensure cfaV1 properly initialized
- add tests to ensure revert occurs when attempting to call hook functions from outside of CFAv1
- tidy up upgradability mock contracts (given new storage variable)
- call validateStorageLayout for one of the upgraded contract tests

Subject: [PATCH 44/88] Ops flow cleanup

- delete updateLogicContracts() function
- delete SuperTokenFactoryHelper
- delete _updateSuperTokenLogic function (future updates will no longer follow this path)
- use SuperTokenDeployerLibrary.deploySuperTokenLogic to deploy non upgradeable super token
- fix breaking tests
- create some abstracted functions for deploy external library and linking

 ## Unreleased
 
+### Breaking
+- `SuperTokenFactory` contract no longer takes `SuperTokenHelper` contract in its constructor
+  - Migration: Pass in a deployed `SuperToken` (logic) contract address to `SuperTokenFactory` constructor instead
+
+### Changed
+- `_superTokenLogic` field in `SuperTokenFactory` contract is now a public immutable field and the previous storage variable is removed
+
 ### [v1.5.0] - 2022-12-19
 ### Added
 - `batchCall` supports new `send` batch operation

Subject: [PATCH 49/88] Initial cleanup after discussion

- remove try/catch in ConstantFlowAgreementV1
- rename CFAv1NFTMocks to CFAv1NFTUpgradabilityMocks
- create seperate CFAv1NFTMock.t.sol file
- Move NFT deployment stuff to CFAv1NFTBase (this will change again)

Subject: [PATCH 51/88] further cleanup

- rename initializeNFTContracts to setNFTProxyContracts
- add immutable _constantOutflowNFTLogic and _constantInflowNFTLogic
- deprecate non-upgradeable path in SuperTokenFactory
- fix up build

Subject: [PATCH 59/88] SuperToken NFT deployAndSet

- setNFTProxyContracts removed on SuperToken
- setNFTProxyContracts added to SuperTokenMock
- deployAndSetNFTProxyContracts added to SuperToken
- rename immutable variables on SuperToken
- fix deploy-framework.js given new SuperToken
- remove code from deploy-super-token.js
- fix SuperTokenV1Library.CFA.test.ts
- rename ForkTester
- move stuff from FoundrySuperfluidTester back to CFAv1NFTBase
- fix up NFT tests to use superTokenMock

Subject: [PATCH 63/88] cleanup

- undo noisy changes
- rename deployer to admin signer
- remove DeployerBase helper contract
- add code from DeployerBase to FoundrySuperfluidTester
- add check to onUpdate to only emit event if an NFT exists

Subject: [PATCH 64/88] fix codeChanged issue

- it was due to external library address being appended in bytecode, reused same pattern used for IDA to handle this (reusing deployed library).
- we should reevaulate this, probably requires another level of checking if the library bytecode has changed

Subject: [PATCH 73/88] clean up interfaces

- clean up IConstantInflowNFT and IConstantOutflowNFT
  - inherit from IFlowNFTBase and delete functions defined in IFlowNFTBase
- add missing functions to IFlowNFTBase
- ConstantInflow and ConstantOutflowNFT inherit from respective interfaces
