v1.0.8-beta

This release helps new node to join the network when the low fee transactions are congested by allowing node to add txn fee for generate id txn automatically and also being able to include more small size low fee txn per block:

• Add RegisterIDTxnFee to control txn fee when generating id
• Add LowFeeTxnSizePerBlock to control low fee txn size per block (it is now recommended to use LowFeeTxnSizePerBlock instead of NumLowFeeTxnPerBlock to control low fee txn in block)
