 There are two ways to use Simple Assets:  
 
 1) As an "ownership authority".  When deployed on an EOSIO chain, Simple Assets will be a separate contract which other Dapps can call to manage their digital assets.  This serves as an additional guarantee to users of the Dapp that the ownership of assets is managed by a reputable outside authority, and that once created, the Dapp can only manage the asset's mdata.  All the ownership-related functionality exists outside the game.

 2) Dapps can Deploy their own copy of Simple Assets and make modifications to have greater control of functionality.  We consider this an example of a dapp being its own "ownership authority."  Before deploying, Simple Assets should be modified to prevent anyone from making assets.

+# Change Log v0.3.1
+- Internal action for NFT `createlog` added. Used by create action to log assetid so that third party explorers can easily get new asset ids and other information.
+- New singelton table `tokenconfigs` added. It helps external contracts parse actions and tables correctly (Usefull for decentralized exchanges, marketplaces and other contracts that use multiple tokens).
+  Marketplaces, exchanges and other reliant contracts will be able to view this info using the following code.
+	```
+	Configs configs("simpl1assets"_n, "simpl1assets"_n.value);
+	configs.get("simpl1assets"_n);
+	```
+- added action `updatever`. It updates version of this SimpleAstes deployment for 3rd party wallets, marketplaces, etc;
+- New examples for Event notifications: https://github.com/CryptoLions/SimpleAssets-EventReceiverExample
