cita v0.22.0 Release Notes

Release Date: 2019-03-29 // about 5 years ago

  • ⬆️ Upgrade Note

    🔧 The v0.22.0 version of the node configurations is compatible with the v0.21 version. 🔧 Means that you can run v0.22.0 directly using the v0.21 node configurations. 🔨 However, due to the refactoring of the network, the nodes executed with v0.22.0 are incompatible with the original nodes (they have different node discovery and transfer protocols), ⬆️ so all nodes need to be upgraded to v0.22.0 at the same time.

    ⬆️ Following [Upgrade Instructions] to upgrade the nodes.

    🆕 New Feature Description

    The new feature of integrating p2p to network service, we add discovery of the network node 🔧 when the original configuration is compatible. But we still need to make some changes to the 🔧 network configuration file definition:

    The old version network.toml looks like:

    port = 4000
enable_tls = true
id_card = 9
[[peers]]
    ip = "127.0.0.1"
    port = 4001
    common_name = "test1.cita"
[[peers]]
    ip = "127.0.0.1"
    port = 4002

    In the version of v0.22.0, we will discard the item id_card and common_name.

    In the old version, when a new node is added to the network, we need to change the item [[peers]] in all nodes' network.toml to reconstruct the network. It is a very complicated operation. But in v0.22.0, the item [[peers]] means known nodes in the network, you can set only one [[peers]], then it can discovery all the network nodes through a discovery protocol.
