ckb 0.100.0 (c978940 2021-09-13)

This version is compatible with v0.25.0 and above. However, it is recommended to upgrade the node, since we will only release security patches based on the latest release.

See how to connect to various chains in Wiki.

The version v0.100.0 will bring incompatible changes for the next hard fork but it will not activate the hard fork for testnet and mainnet. So it is compatible with the current testnet and mainnet.

• The block header as a new field extra_hash, which replaced uncles_hash.
• The block has a new field extension but no blocks may set it before the hard fork activation.
• The field hash_type has a new allowed value "data1" but it is invalid before the hard fork activation.
• The default value of the parameter OutputsValidator in the JSON RPC send_transaction is well_known_scripts_only now. See #2821 for details.

  The data of epoch in bytes is not same as the EpochNumberWithFraction, which causes a few unintended consequences.

  • Deny unknown configuration items.

    To avoid several kinds of mistakes, for example, typos.

    • Not list in the default configuration files.
    • Be tagged as "Experimental".

  • The default configuration files will not include any deprecated configuration items.

  • The default configuration files will not enable any experimental configuration items.
