- Evidence-based topology with observed and inferred relationships, parallel links, port channels, role inference, HSRP and STP presentation.
- Vector topology PDF export with A3/A4, Standard/Technical, inferred-link and Confidential options.
- Manual and scheduled activities through the background Agent.

## Upgrade behaviour

A forward major upgrade detects the existing product, preserves Product Administrator authority and retained customer state, and skips fresh-install provisioning. Older packages and different packages using the same version are blocked. Always validate the exact predecessor package in staging before production rollout.

## Installer maintenance

Installation components have been updated while preserving the supported installation and upgrade workflow. Package names, per-machine scope, guided Product Administrator selection, silent deployment properties, service identity, logging and offline behaviour are unchanged. No change to existing Opia install commands is required.

## SSH security maintenance

The SSH connectivity component has been updated to the current supported release. Existing device login, host-key verification and Cisco collection workflows remain unchanged. Exact third-party component versions and attribution are listed in Third-party Notices.

## Current limitations

- Device command availability varies by Cisco platform, release, enabled feature and privilege.
- Topology inference requires operator review and is not equivalent to directly observed CDP/LLDP evidence.
- Activation is designed for offline request/import rather than internet-based activation.
- Device collection in this release targets supported Cisco IOS and IOS-XE platforms.
