Global Priority

HIGH: This is a high priority release and you must upgrade as as soon as possible if you are validator

• runtime version 11 -> 12 at #3038400
• Substrate V2.0.0 -> Substrate V3.0.0
• Storage Migrations Checklist: #604

How to sync blocks from genesis(block #0)

• (0) You should know Debug: panicked at 'Storage root must match that calculated ' #609
  if you use ChainX v4.0.0 directly sync blocks will be stuck at #881910 or other block.
• (1) Compile ChainX v3.0.0 by nightly-2020-09-30 or Download chainx-v3.0.0-ubuntu20.04-x86_64-unknown-linux-gnu-1
• (2) Until #3038400, please use ChainX v3.0.0 to synchronize with NativeElseWasm (default mode)
• (3) For blocks after #3038400, complete (2) first, and then replace ChainX v3.0.0 with ChainX v4.0.0 to complete the db migration (note that the migration process is irreversible, it is recommended to back up the data first)
• (4) ChainX v4.0.0 continues to synchronize blocks
• (5) if you are validator, replace your ChainX v3.0.0 by ChainX v4.0.0 node as soon as possible before #3038400
