v4.2 Release Notes

This document describes all new features and changes in the release. The format is based on Keep a Changelog and this project adheres to Semantic Versioning.

Release Overview

  • Added a new OS Upgrades view with a button to run an OS upgrade job.
  • Added a "Skip File Size Check" toggle to the Transfer Software Image to Device and Execute OS Upgrade Workflow jobs.
  • Added a post-reboot delay that runs before the post-check that defaults to 30 seconds.

v4.2.0 (2026-04-30)

Added

  • Added list view for OS Upgrades.
  • Added "Execute OS Upgrades" button to OS Upgrades list view.
  • Added a "Skip File Size Check" toggle to the Transfer Software Image to Device and Execute OS Upgrade Workflow jobs. The job now resolves the image size from the Software Image File (or probes the download URL's Content-Length when absent) by default so pyntc can validate the target device's available disk space before starting the transfer; check the toggle to bypass that validation.
  • Added a post-reboot delay that runs before the post-check that defaults to 30 seconds.

Changed

  • Updates the skip file size description.

Fixed

  • Fixed the Transfer Software Image to Device job so insufficient-disk-space failures reported by pyntc are surfaced as an explicit "Insufficient disk space on device" error instead of a generic transfer or checksum failure.

Dependencies

  • Updated pyntc to 2.4.0 to pick up per-platform pre-transfer free-space checks for EOS, IOS, NX-OS, Junos, and ASA.
