Gele CLI 1.5.97 upgrade has been completed.

It is an important Hard Fork client. All Elementrem Network users must use this version.

The Elementrem network will be undergoing a hard fork at block number 1,900,000 (Roughly expected to be around May 9, 2017).

EIP 150 Hard Fork
Long-term gas cost changes for IO-heavy operations to mitigate transaction spam attacks.
This will reprice certain operations to correspond better to the underlying computational complexity.
Increase the gas cost of EXTCODESIZE to 700
Increase the base gas cost of EXTCODECOPY to 700
Increase the gas cost of BALANCE to 400
Increase the gas cost of SLOAD to 200
Increase the gas cost of CALL, DELEGATECALL, CALLCODE to 700
Increase the gas cost of SUICIDE to 5000
Increase the recommended gas limit target to 5.5 million
If a call asks for more gas than the maximum allowed amount, do not return an OOG error; instead, call with the maximum allowed amount of gas

Spurious Dragon Hard Fork
EIP 155: Replay attack protection : prevents transactions from one Elementrem chain from being rebroadcasted on an alternative chain.
EIP 160: EXP cost increase : adjusts the price of EXP opcode so it balances the price of EXP with the computational complexity of the operation, essentially making it more difficult to slow down the network via computationally expensive contract operations.
EIP 161: State trie clearing
EIP 170: Contract code size limit : changes the maximum code size that a contract on the blockchain can have. This update prevents an attack scenario where large pieces of account code can be accessed repeatedly at a fixed gas cost.

Tron Recursive Hard Fork
Block mining reward is reduced to 1/5 and BlockTaget(13sec) does not change.
BlockReward = 5 ELE -> 1 ELE
