The Apache PLC4X team is pleased to announce the release of Apache PLC4X 0.9.1

This is a bugfix release aiming at directly fixing CVE-2021-43083 as
well as updating the dependency to Log4J 2.14.0 which was affected by
CVE-2021-44228

Please note that CVE-2021-43083 only affects the PLC4C part of PLC4X.

PLC4X is a set of libraries for communicating with industrial programmable

The current release contains drivers able to communicate with
industrial PLCs using one of the following protocols:

  *   AB-ETH

  *   CanOpen
  *   EtherNet/IP / EIP
  *   Firmata
  *   KNXNet/IP
  *   Modbus
  *   OPC UA
  *   Siemens S7 (0x32)

Beyond that we also provide integration modules for the following
Apache projects and frameworks:

  *   Apache Calcite
  *   Apache Camel
  *   Apache Edgent (Incubating / Retired)
  *   Apache Kafka (Kafka Connect)
  *   Apache NiFi
  *   Logstash

It also provides an `OPC UA Server` which can act as a bridge between
legacy systems and OPC UA.
