fabric1.1新增

################################################################################
#
#   SECTION: Capabilities
#
#   - This section defines the capabilities of fabric network. This is a new
#   concept as of v1.1.0 and should not be utilized in mixed networks with
#   v1.0.x peers and orderers.  Capabilities define features which must be
#   present in a fabric binary for that binary to safely participate in the
#   fabric network.  For instance, if a new MSP type is added, newer binaries
#   might recognize and validate the signatures from this type, while older
#   binaries without this support would be unable to validate those
#   transactions.  This could lead to different versions of the fabric binaries
#   having different world states.  Instead, defining a capability for a channel
#   informs those binaries without this capability that they must cease
#   processing transactions until they have been upgraded.  For v1.0.x if any
#   capabilities are defined (including a map with all capabilities turned off)
#   then the v1.0.x peer will deliberately crash.
#
################################################################################
Capabilities:
    # Channel capabilities apply to both the orderers and the peers and must be
    # supported by both.  Set the value of the capability to true to require it.
#通道的性能必须同时支持orderers和peers，默认值设为true
    Global: &ChannelCapabilities
        # V1.1 for Global is a catchall flag for behavior which has been
        # determined to be desired for all orderers and peers running v1.0.x,
        # but the modification of which would cause incompatibilities.  Users
        # should leave this flag set to true.
        V1_1: true

    # Orderer capabilities apply only to the orderers, and may be safely
    # manipulated without concern for upgrading peers.  Set the value of the
    # capability to true to require it.
#orderer只需要功能上适配orderers节点，不用担心peers节点更新对操作的影响。默认为true
    Orderer: &OrdererCapabilities
        # V1.1 for Order is a catchall flag for behavior which has been
        # determined to be desired for all orderers running v1.0.x, but the
        # modification of which  would cause incompatibilities.  Users should
        # leave this flag set to true.
        V1_1: true

    # Application capabilities apply only to the peer network, and may be safely
    # manipulated without concern for upgrading orderers.  Set the value of the
    # capability to true to require it.
#同样的application只需要适配peer网络，不必担心orderers的更新默认值同样为true
    Application: &ApplicationCapabilities
        # V1.1 for Application is a catchall flag for behavior which has been
        # determined to be desired for all peers running v1.0.x, but the
        # modification of which would cause incompatibilities.  Users should
        # leave this flag set to true.
