2025.2.1 Release Notes

Build Number: 2025.2.1.18 Last updated: 05/28/2025

Important Notice for OnPrem partners upgrading to 2025.2.1 from a version earlier than 2025.1.

N-central 2025.1 replaced the underlying operating system on N-central from CentOS to AlmaLinux.

If you are upgrading from a version of N-central earlier than 2025.1 you will be doing a complete operating system migration. This is a significant upgrade to N-central with new system requirements and the upgrade will take longer than a normal upgrade.

We highly recommend reviewing the updated system requirements and release notes for essential details before proceeding with the upgrade.

We’re introducing exciting new features, enhancements, and critical fixes to improve usability, security, and performance. Here’s what’s in the 2025.2.1 release:

What's New in 2025.2.1

The HaloPSA Integration and Autotask REST API features are available as Preview in this release. These features will be rolled out progressively across partners who are interested in participating in this preview.

This approach allows us to monitor adoption and gather feedback to better understand the impact of these new capabilities on existing workflows and integrations before we proceed with a broader rollout.

Enable Coexistence of SOAP and REST APIs for the Autotask Integration

• The Autotask SOAP API was originally scheduled to reach End-of-Life (EOL) in December 2024, but this plan has since been retracted. While the SOAP API has not officially reached EOL, it is in the process of being sunset, with a new retirement date yet to be announced.

• To support a smooth transition, we are enabling coexistence of both SOAP and REST APIs for the Autotask integration. This gives partners the flexibility to continue using their current SOAP 1.5 configurations while gradually migrating to REST, minimizing operational impact.

• We are currently inviting interested partners to preview the REST API integration.

Dedicated native integration with HaloPSA (Professional Services Automation) inside N-central

• Unified User Experience

  • All configuration and operations are managed directly within N-central.

  • No need to switch between HaloPSA and N-central or use third-party connectors

• Device & Customer Mapping: Easily map devices and customers between N-central and HaloPSA for accurate service tracking and streamlined workflows.

• Automated Ticketing:

  • Automatically create and update tickets in HaloPSA based on N-central alerts.

  • Two-way sync ensures ticket statuses remain aligned across both platforms.

• Time Entry Support: Time entries logged in N-central are now reflected in HaloPSA tickets, even when the Billing step is hidden.

• Credential Management:

  • Securely store and manage HaloPSA API credentials in N-central.

  • Includes a "Test Connection" feature to validate your integration setup.

• Optimized via HaloPSA APIs: All integration operations—ticketing, asset sync—leverage HaloPSA API endpoints.

• Improved Time Entry User Matching: The integration now supports listing API-only users from HaloPSA.

N-central Agent Compatibility for Windows Server 2025

The latest update of the N-central Windows Agent now offers enhanced support for Windows Server 2025 assets, enabling seamless deployment and reliable performance across next-generation Windows Server environments.

CMMC Mode Enablement: Laying the Groundwork for CMMC Compliance

• As part of our long-term commitment to CMMC compliance, this release introduces foundational features that prepare the platform for secure, CMMC-aligned operation.

• Upgraded Struts Library to Version 6.4

• Enhanced Authentication using the following changes:

  • IDP Access Token Expiration Enforcement

    Implemented enforcement of expired identity provider (IDP) access tokens in N-central. When an IDP token expires, users are now automatically logged out and prompted to reauthenticate, ensuring secure session handling. To prevent frequent logouts, administrators are advised to extend the token lifespan within their identity provider settings, if permitted by your organization’s security policies.

  • Identity Management – SSO Unlink Behavior

    When a user is unlinked from an SSO provider (Azure or generic), N-central now displays a warning message outlining the impact of this action. If the user proceeds with the unlinking, their active session is automatically invalidated, and they are prompted to log in again using local authentication.

Bug Fixes

Category	Updated Summary	Issue Key
Core	Improved Probe Task Scheduling to Reduce Stale Service States Issue: Several services monitored by probes were displaying as stale, particularly in high-load environments. This was indicated by missing or blank "Last Scan Time" values. The root cause was the probe's limited task scheduling capacity, which struggled to manage a large number of simultaneous tasks efficiently. Fix: An enhanced task scheduler was introduced to optimize how the probe handles and prioritizes tasks.	NCCF-626897

Backups

Description

Issue

Scheduled system backups may not run after fresh installations of N-central 2025.1 and N-central 2025.2. On demand backups continue to work as expected. Also if N-central was upgraded from a previous version it will continue to work as expected. If you experience an issue with Scheduled system backups after a fresh installation of N-central 2025.1 or N-central 2025.2 please reach out to support for further assistance.

Integrations

Description

Underscore in PSA Integration URL Blocked by UI Validation Users attempting to integrate with PSA platforms using underscores in their endpoint URLs may be unable to complete configuration through the N-central UI for example, api_example.psa.com. This restriction is enforced by the UI only; backend systems and DNS do not block such URLs. The limitation is based on SEO and analytics best practices, where underscores are discouraged due to compatibility concerns with parsing and indexing tools.

Remote Control

Description	Issue
Web SSH, SSH, Custom remote-control options for windows will not dynamically request an updated path when the saved path is not correct and instead provide a terminal error message requesting the user update the remote control settings path	NCCF-506138
Web SSH, SSH, Custom remote-control options will not work when launched from a MAC or Linux client	NCCF-414079
While calculating the size of the required disk space we look at the size of the last backup on the system, the last system backup on the system must have the "Include Historical Data" option selected in order for the upgrade calculation to be accurate when assessing enough disk space is available. Alternatively downloading then deleting all backups from the system to ensure the backup partition has enough space is an option. Review N-able N-central Backup for details.	-
