 * Removed individual mappings for tier data removed in UDSTSTO.
 * Removed the old Proxy deployment method of USDTieredSTO and adopt the new inherited proxy deployment approach.
 * Bump the version to `2.1.0`
-* Added `getAccreditedData` to return accredited & non-accredited investor data
+* Added `getAccreditedData` to return accredited & non-accredited investor data.
+* Event `TokenPurchase` has uint256 tier instead of uint8 tier.  
+* Event `SetAddresses` has non-indexed array of address of `_usdTokens` rather than single indexed address.
+* Added `getUsdTokens()` function that returns array of accepted stable coin (usd token) addresses.
+* Pass an array of `_usdToken` address in `configure` function instead of singleton address. This will require changes in bytes data generation when deploying a usdtsto through factory.
 
 ## GeneralTransferManager
 * `getInvestors`, `getAllInvestorsData`, `getInvestorsData` added to GTM to allow easy data queries.
-* `modifyDefaults(uint64 _defaultFromTime, uint64 _defaultToTime)` added which sets a default timestamp used when `fromTime` or `toTime` are 0
+* `changeDefaults(uint64 _defaultFromTime, uint64 _defaultToTime)` added which sets a default timestamp used when `fromTime` or `toTime` are 0.
 * Add `address[] public investors` to record a list of all addresses that have been added to the whitelist (`getInvestors`).
-* General Transfer Manager: Fix for when `allowAllWhitelistIssuances` is FALSE
-* General Transfer Manager: Make GTM a Proxy based implementation to reduce deployment gas costs
+* Fix for when `allowAllWhitelistIssuances` is FALSE
+* Make GTM a Proxy based implementation to reduce deployment gas costs
 * Changed the version of `GeneralTransferManagerFactory` from `1.0.0` to `2.1.0`.
+* `_investor` and `_addedBy` is now indexed in the `ModifyWhitelist` event.
+* Add public variable `defaults` to get the offset timing.
 
 ## Manual Approval TransferManager
 * Removed `0x0` check for the `_from` address to `ManualApprovalTransferManager`. This allows for the Issuer/Transfer Agent to approve a one-off mint of tokens that otherwise would not be possible.
@@ -39,13 +45,35 @@ All notable changes to this project will be documented in this file.
 * Add `getApprovalDetails()` to get the details of the approval corresponds to `_from` and `_to` address.
 * Add feature to modify the details of the active approval using `modifyApproval()` & `modifyApprovalMulti()`.
 * Add `addManualApprovalMulti()` and `revokeManualApprovalMulti()` batch function for adding and revoking the manual approval respectively.
+* Add `_description` parameter during the `addManualApproval()` function call. It will be a `bytes32` variable which depicts the cause of manual approval.
+* Remove `addManualBlocking()` , `revokeManualBlocking()` functions.
+* Add `getTotalApprovalsLength()` to get the number of active approvals.
+* Add `getAllApprovals()` to get the details of all approvals.
 
 ## Dividends
 * Changed the version of `ERC20DividendCheckpointFactory` & `EtherDividendCheckpointFactory` from `1.0.0` to `2.1.0`.
-* Applied proxy pattern to Dividends modules
+* Applied proxy pattern to Dividends modules.
+* During the launch of dividend module issuer need to pass the reclaimed wallet that receive the left over funds from the module.
+i.e pass `_wallet` in `configure()` function of dividend module. It emits `SetWallet` event for the confirmation of the same.
+* Add `changeWallet()` function to change the reclaimed wallet address (only be called by the owner).
+* Add `getDividendsData()` getter to receive the details about all the dividend.
+* Add `getDividendData()` getter to receive the details about the particular dividend by passing a corresponding dividend index.
+* Add `getDividendProgress()` getter to retrieves the list of investors and their details corresponds to particular dividend.
+* Add `getCheckpointData()` use to retrieves list of investors, their balances, and their current withholding tax percentage corresponds to checkpointId.
+* `isExcluded()` a view function added to check whether an address is excluded from claming a dividend or not.
+* `isClaimed()` a view function added to checks whether an address has claimed a dividend or not.
+*  DividendIndex is indexed in the events `ERC20DividendClaimed`, `ERC20DividendReclaimed`, `ERC20DividendWithholdingWithdrawn`. Similarly for the Ether dividend module `EtherDividendClaimed`, `EtherDividendReclaimed`, `EtherDividendClaimFailed`, `EtherDividendWithholdingWithdrawn`.
+* `EXCLUDED_ADDRESS_LIMIT` changed from 50 to 150.
 
 ## Experimental modules
 * Remove the `SingleTradeVolumeRestrictionTMFactory.sol` and its corresponding module `SingleTradeVolumeRestrictionTM.sol`.
+* Add the new TM called `BlacklistTransferManager.sol` and its corresponding factory `BlacklistTransferManagerFactory.sol`.
+* Chnage the name of module from `LockupVolumeRestrictionTM.sol` to `LockUpTransferManager.sol`, similarly factory become `LockUpTransferManagerFactory.sol`.
+* Add new module called `VestingEscrowWallet.sol` and its corresponding factory `VestingEscrowWalletFactory.sol`.
+
+## STR & MR
+* `getArrayAddress(), getArrayBytes32(), getArrayUint()` are now public getters.
+*  `getUintValues(), getBoolValues(), getStringValues(), getAddressValues(), getBytes32Values(), getBytesValues()` rename to `getUintValue(), getBoolValue(), getStringValue(), getAddressValue(), getBytes32Value(), getBytesValue()`. #488
 
 ## Added
 * Add new module called `VolumeRestrictionTM.sol` under the TransferManager modules list. It will be used to restrict the token
