v1.3.0

Note that v1.3.0 has a hardfork, which will be activated at block height 12,289,321 (7/22/2021 ~2pm PDT) on IoTeX mainnet.

v1.3 has upgraded to latest EVM version so user can confidently deploy their DApps to IoTeX blockchain. This EVM upgrade supports the ChainID opcode to prevent relay attacks and enable cross-chain transparency, and has optimized gas costs of certain opcodes, especially privacy and zk computations.

Optimized block sync strategy to make it more robust
Fixed a bug that API query needs to wait a little while to return the latest committed block
Fixed a bug that node stops working after network connectivity is lost. Now the node can detect the network loss/reconnect event, and automatically resume working after network connectivity is restored

v1.2.0

web3js compatibility. With v1.2 user can connect their favorite tools in the
Ethereum eco-system (such as Metamask, Subgraph) to IoTeX blockchain simply by
setting up RPC endpoint to IoTeX endpoint
Support multiple chain DB files. v1.2 will now generate 1 db file for every
1,000,000 accumulated blocks added to the blockchain. This prevents one single
overly large db file in the long run, and opens up possibility for faster and
incremental download (only need to download new latest db files)
Reduced DB file size. Together with the multiple DB files feature, the DB file
itself has been overhaualed by using an improved block storage with better
compression. The estimated storage saving is about 30~40% when enabling v1.2
Added EVM revert message in transaction receipt. For contract calls that get
reverted in the middle, we can now see the actual revert error message from the
transaction receipt
Improved transaction indexing scheme. As a result, certain API queries (for
example, pull all transactions from an address within a block range) now get a
much faster response
Improved p2p connection reliability and network robustness
Fix ioctl crashes in Ubuntu when creating an action
