+# v1.2 Release Note
+
+### v1.2 Release Note
+1. 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
+2. 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)
+3. 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
+4. 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
+5. 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
+6. Improved p2p connection reliability and network robustness
+7. Fix ioctl crashes in Ubuntu when creating an action
