Hello everybody,

we're proud to announce the availability of collectd 5.6.0. This release adds
many new features; to learn about all new features available, please see
the ChangeLog below. Let's quickly highlight three new plugins:

  * The gRPC plugin implements an gRPC client and server in collectd.
    The server accepts requests for submitting metrics to the daemon and
    can list available metrics. The client can be used to send metrics
    to a compatible gRPC server, for example another collectd instance.
    collectd's Go package has already been updated to implemented both
    client and server as well, allowing easy interaction between
    collectd and Go code.

  * The MQTT plugin implements communication via MQTT, a lightweight
    messaging protocol. MQTTs small footprint makes it quite popular
    with embedded devices and situations in which connections are

  * The cpusleep plugin determines the amount of time CPUs have spent in
    deep sleep. Battery powered devices often turn of the CPU completely
    to minimize power usage.


The new version is available in source-code form from collectd's
download page. The direct download links are:
