@@ -37,71 +37,47 @@ For this project, the security procedures applied/being finished are:
 - The test suite of the codebase itself.
 - Certora audit/property checking for all the dynamics of the `stataToken`, including respecting all the specs of [EIP-4626](https://eips.ethereum.org/EIPS/eip-4626).
 
-## Upgrade Notes Umbrella
+## Upgrade Notes StataTokenV2
 
 ### Inheritance
 
-Interface inheritance has been changed so that `IStaticATokenLM` implements `IERC4626`, making it easier for integrators to work with the interface.
-The current `Initializable` has been removed in favor of the new [Initializable](https://github.com/OpenZeppelin/openzeppelin-contracts-upgradeable/blob/9a47a37c4b8ce2ac465e8656f31d32ac6fe26eaa/contracts/proxy/utils/Initializable.sol) following the [`ERC-7201`](https://eips.ethereum.org/EIPS/eip-7201) standard.
-To account for the shift in storage, a new `DeprecationGap` has been introduced to maintain the remaining storage at the current position.
+The `StaticATokenLM`(v1) was based on solmate.
+To future proof the `StataTokenV2`(v2) the implementation is now based on [open-zeppelin-upgradeable](https://github.com/OpenZeppelin/openzeppelin-contracts-upgradeable) which relies on [`ERC-7201`](https://eips.ethereum.org/EIPS/eip-7201) to isolate storage per contract.
+This will allow for more flexible addition of extensions in the future.
 
-### Misc
+The `StataTokenV2` is seperated in 3 different contract, where `StataTokenV2` inherits `ERC4626StataToken` and `ERC20AaveLM`.
 
-Permit params have been excluded from the METADEPOSIT_TYPEHASH as they are not necessary.
-Potential frontrunning of the permit via mempool observation is unavoidable, but due to wrapping the permit execution in a `try..catch` griefing is impossible.
+- `ERC20AaveLM` is an abstract contract implementing the forwarding of liquidity mining from an underlying AaveERC20 - an ERC20 implementing `scaled` functions - to a wrapper contract.
+- `ERC4626StataToken` is an abstract contract implementing the [EIP-4626](https://eips.ethereum.org/EIPS/eip-4626) methods for an underlying aToken. In addition it adds a `latestAnswer`.
+- `StataTokenV2` is the main contract stritching things together, while adding `Pausability`, `Rescuability`, `Permit` and the actual initialization.
 
-### Features
+### MetaTransactions
+
+MetaTransactions have been removed as there was no clear use-case besides permit based deposits ever used.
+To account for that specific use-case a dedicated `depositWithPermit` was added.
+
+### Direct AToken Interaction
+
+In v1 deposit was overleaded to allow underlying & aToken deposits.
+While this appraoch was fine it seemed unclean and caused some confusion with integrators.
+Therefore v2 introduces dedicated `depositATokens` and `redeemATokens` methods.
 
 #### Rescuable
 
 [Rescuable](https://github.com/bgd-labs/solidity-utils/blob/main/src/contracts/utils/Rescuable.sol) has been applied to
-the `StaticATokenLM` which will allow the ACL_ADMIN of the corresponding `POOL` to rescue any tokens on the contract.

 #### Pausability
 
-The `StaticATokenLM` implements the [PausableUpgradeable](https://github.com/OpenZeppelin/openzeppelin-contracts-upgradeable/blob/9a47a37c4b8ce2ac465e8656f31d32ac6fe26eaa/contracts/utils/PausableUpgradeable.sol) allowing any emergency admin to pause the vault in case of an emergency.

 As long as the vault is paused, minting, burning, transfers and claiming of rewards is impossible.
 
 #### LatestAnswer
 
-While there are already mechanisms to price the `StaticATokenLM` implemented by 3th parties for improved UX/DX the `StaticATokenLM` now exposes `latestAnswer`.
-`latestAnswer` returns the asset price priced as `underlying_price * excahngeRate`.
+While there are already mechanisms to price the `StataTokenV2` implemented by 3th parties for improved UX/DX the `StataTokenV2` now exposes `latestAnswer`.
+`latestAnswer` returns the asset price priced as `underlying_price * exchangeRate`.
 It is important to note that:
 
 - `underlying_price` is fetched from the AaveOracle, which means it is subject to mechanisms implemented by the DAO on top of the Chainlink price feeds.
 - the `latestAnswer` is a scaled response returning the price in the same denomination as `underlying_price` which means the sprice can be undervalued by up to 1 wei
 - while this should be obvious deviations in the price - even when limited to 1 wei per share - will compound per full share

-
-### Umbrella upgrade plan
-
-The upgrade can be performed independent(before) from any umbrella changes as it has no dependencies.
-The upgrade will need to:
-
-- upgrade the `StaticATokenFactory` with a new version, replacing the `STATIC_A_TOKEN_IMPL`.
-- upgrade existing stata tokens via `upgradeToAndCall` to the new implementation. While the tokens are already initialized, due to changing the `Initializable` the corresponding storage is lost.
