-New settings allow reading of the hash algorithm used to mine a particular block for coins that support this feature and have the algorithm data stored in the raw block data
-An "Algorithm" column has been added to the block page and main transaction homepage when multi-algo data is enabled
-The /ext/getlasttxs api will now return the hash algorithm if reading of the multi-algo data is enabled
-Adds a tx_type field to the tx model which is typically null for "normal" transaction types, but can also display 'p2pk' for bitcoin txes which require addtional encoding to reveal the P2PKH address as well as 'zksnarks' for transactions with hidden sender or receiver data
-Additional fixes for how data is displayed when a valid wallet address cannot be found
-Includes some small updates to how zksnarks transactions display hidden sender/receiver data
-Replace tabs with double-spaces
-Betting spacing and lining up of code functions
-Add missing semi-colons
-Remove extra characters and spaces where applicable
-Remove commented-out code fragments
-Add missing 2021 date to LICENSE
