How to Upgrade

If you are running version relese_v0.3.9 and before, you should shut it down and wait until it has completely closed, then just copy over ela (on Linux).

However, as usual, config, keystore and chaindata files are compatible.


Elastos.ELA is supported and extensively tested on operating systems using the Linux kernel. It is not recommended to use Elastos.ELA on unsupported systems.

Elastos.ELA should also work on most other Unix-like systems but is not as frequently tested on them.

As previously-supported CPU platforms, this release's pre-compiled distribution provides binaries for the x86_64 platform.

Notable changes

  • New CR related transactions, inclouding register,update, unregister and return transcations.
  • The first upgrade node carries out the old data migration, and the block stored by the leveldb is transferred to the ffldb.
  • Faster processing of transaction.
  • Faster processing of block.
