-## CappedSTO 2.0.1
+
+## CappedSTO 2.1.0
 * `rate` is now accepted as multiplied by 10^18 to allow settting higher price than 1ETH/POLY per token.
 * Indivisble tokens are now supported. When trying to buy partial tokens, allowed full units of tokens will be purchased and remaining funds will be returned.
 
 ## USDTieredSTO 2.1.0
+* Added `stableCoinsRaised` function that returns amount of individual stable coin raised when address of that stable coin is passed.
+* Added support for multiple stable coins in USDTSTO.
 * Added `buyTokensView` and `getTokensMintedByTier` to USDTSTO.
 * Added `getSTODetails` to USDTSTO.
 * Added an Array of Tiers that will hold data about every tier in USDTSTO.
