What's Changed in Release 22.2R3

Juniper Extension Toolkit (JET)

  • Python 3 is the default and only Python version for executing Juniper Extension Toolkit Python scripts (ACX Series, PTX Series, and QFX Series)—Junos OS Evolved supports only Python 3 for executing Juniper Extension Toolkit (JET) scripts written in Python. Python 2.7 is no longer supported for executing JET scripts, and we've deprecated the language python statement at the [edit system scripts] hierarchy level.

Junos XML API and Scripting

  • Python 3 is the default and only Python version for executing commit, event, op, and SNMP Python scripts (ACX Series, PTX Series, and QFX Series)—Junos OS Evolved supports only Python 3 for executing commit, event, op, and SNMP scripts written in Python. Python 2.7 is no longer supported for executing these types of scripts, and we've deprecated the language python statement at the [edit system scripts] hierarchy level.

Network Management and Monitoring

  • Python 3 is the default and only Python version for executing YANG action and translation Python scripts (ACX Series, PTX Series, and QFX Series)—Junos OS Evolved supports only Python 3 for executing YANG action and translation scripts written in Python. Python 2.7 is no longer supported for executing YANG action and translation scripts, and we've deprecated the language python statement at the [edit system scripts] hierarchy level.

  • Support for the junos:cli-feature YANG extension (ACX Series, PTX Series, and QFX Series)—The cli-feature YANG extension identifies certain CLI properties associated with some command options and configuration statements. The Junos YANG modules that define the configuration or RPCs include the cli-feature extension statement, where appropriate, in schemas emitted with extensions. This extension is beneficial when a client consumes YANG data models, but for certain workflows, the client needs to generate CLI-based tools.

User Interface and Configuration

  • The file copy command supports only text-formatted output in the CLI (ACX Series, PTX Series, and QFX Series)—The file copy command does not emit output when the operation is successful and supports only text-formatted output when an error occurs. The file copy command does not support using the | display xml filter or the | display json filter to display command output in XML or JSON format in any release. We've removed these options from the CLI.
