WPM 2026.1 release notes

Release date: February 10, 2026

Here's what's new in WPM 2026.1. You can find the applicable system requirements here.

To view release notes, system requirements, and product guide PDFs for supported versions of WPM, see WPM previous versions. To view release notes for multiple versions and multiple SolarWinds Platform products on a single page, see the release notes aggregator.

WPM runs on the SolarWinds Platform (self-hosted). WPM release notes include the updates from the SolarWinds Platform (self-hosted).

Attention WPM customers

SolarWinds Observability Self-Hosted 2026.1 includes changes to improve communication between services on polling engines. Because of these changes, you must open TCP port 17734 on the main polling engine to allow inbound traffic from any servers that host additional polling engines, additional web servers, or high availability servers.

If port 17734 is not open on the main polling engine, other servers in your SolarWinds Observability Self-Hosted deployment could become unavailable. See the Known issues below for more information.

New features and improvements in WPM

Security has been improved with software updates

Electron has been updated to version 37.9.0.
Chromium has been updated to version 138.0.7204.251.
Webpack has been updated to version 5.102.1.

New features and improvements in SolarWinds Platform

New All Active Alerts page

All Active Alerts page has been updated to the new framework. You can customize columns or edit the query used to build the table with custom entries.

Custom banners

Users can define customized in-product banners shown at the top of each page in the web console. These banners can be used for the following purposes:

Notification of scheduled upgrades
Classification of government data
Identification of deployments when multiple instances are deployed for a single customer
Notification of a known issue or outage

Maps

This release introduces several enhancements to map editing and management, making it easier to customize and work with Intelligent Maps.

Users can bulk edit multiple connections at once.
Users can import Network Atlas maps with linked backgrounds into Intelligent Maps.
Users must confirm that they want to remove a custom topology item before it is removed.
Users can see an icon and color indicator for text that contains hyperlinks.
Users can see hotkeys for actions in the More menu.
Users can hide autogenerated topology connections on maps.

Updated Maintenance Windows

Maintenance Windows have been improved:

Groups can now be assigned to maintenance windows.
End after X occurrences
Admins can make reasons mandatory for both scheduled and ad-hoc maintenance windows.

Feature Adoption

The Feature Adoption section in My Deployment, which helps you enable and expand the use of key product features, now includes suggestions for:

Gaining deeper insights into virtualization
Monitoring virtual servers
Monitoring storage arrays
Identifying unknown traffic
Monitoring configurations
Monitoring DNS and DHCP servers
Monitoring call quality
Monitoring configuration policies

Integrations

ServiceNow integration now supports OAuth based authentication.

SolarWinds Platform now integrates with SolarWinds Incident Response (earlier known as Squadcast). In this version, the integration is unidirectional - alerts from SolarWinds Platform are forwarded to SolarWinds Incident Response. Any acknowledgments on the incident response side are not reflected in SolarWinds Platform. Users can do additional correlation and suppress alerts using their Incident Response instance.

PerfStack metrics format change

PerfStack metrics now have a short, user-friendly unit format to simplify reading and understanding PerfStack charts. This helps with translating large numbers into more readable language, such as using kb, Mb, Gb instead of bytes.

Node status indicates polling issues

Node status now exposes any problem with failing WMI, WinRM, or SNMP polling when ICMP connection is working, including credential issues.

Updated MAC Organizationally Unique Identifier (OUI) data

The MAC OUI data has been updated to provide more accurate vendor details when analyzing MAC addresses in the SolarWinds Platform.

Support for online upgrades to the previous version

Online upgrades now include the option to upgrade to the previous version. For example, if you're on 2025.4.1 or earlier and 2026.1 becomes available, the Updates page lists 2025.4.3 and 2026.1 as upgrade options.

If the previous version is not displayed, click Update for the latest version, cancel the upgrade session, and then reload the Updates page.

Known issues

Last updated: December 30, 2025

Additional web console and additional polling engines are unavailable, and the Orion Module Engine service repeatedly stops

If port 17734 is not open on your main polling engine to allow inbound traffic from other servers in your SolarWinds Observability Self-Hosted deployment, you could experience issues such as:

Scalability engines such as additional polling engines and additional web servers are unavailable.
The Orion Service Module stops frequently and must be manually restarted.
The Business Layer Log on a scalability engine includes messages such as:

gRPC error calling Feature Service on port 17734: Error starting gRPC call.

Resolution or workaround: Open TCP port 17734 on the main polling engine to allow inbound traffic from servers that host SolarWinds Observability Self-Hosted scalability engines. This includes additional polling engines, additional web servers, and high availability servers.

For more information, see Additional Website and Additional Polling Engines are Down After Upgrade to 2026.1 due to gRPC Error Calling Feature Service on Port 17734.

Upgrades fail when the Configuration Wizard attempts to create or update a configuration file

In some environments, the Configuration Wizard fails when attempting to create or update the sw.web.compression.config file.

Resolution or workaround: This issue will be fixed in a future release. Until then, complete these steps:

Open the following file in a text editor:

C:\ProgramData\SolarWinds\sw.web.compression.config

Update the contents of this file to the following:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <configSections>
        <section name="sw.web.compression" type="SolarWinds.Orion.Core.Common.Configuration.WebCompressionSection, SolarWinds.Orion.Configuration" />
    </configSections>
    <sw.web.compression>
        <settings>
            <add name="" level="4" enable="True" install="True" />
            <add name="static" level="9" />
            <add name="dynamic" />
            <add name="dynamic.IIS6" enable="False" />
        </settings>
    </sw.web.compression>
</configuration>

Save the file and rerun the configuration wizard.

URL-based filters in modern dashboards stopped working

Modern dashboards no longer recognize URL-based filters unless a global filter is explicitly configured on the dashboard.

Resolution or workaround: Use global filters. See Global filters on modern dashboards.

THWACK integration is broken

A new THWACK platform was introduced in 2025. This new platform does not support the API that SolarWinds Platform is using.

Resolution or workaround: Not available. See Shared Templates on Thwack is unable to reach thwack.com in SolarWinds Platform.

Deprecation notice

The following platforms and features are still supported in the current release. However, they will be unsupported in a future release. Plan on upgrading deprecated platforms, and avoid using deprecated features.

SolarWinds Platform Agent support for Windows Server 2008 R2, Windows 7

Windows Server 2008 R2 and Windows 7 reached End of Life and are no longer supported by SolarWinds Platform Agents. To continue monitoring them, consider switching the polling method to remote monitoring with WMI.

SQL Server 2016

SQL Server 2016 is deprecated as of 2025.2. It is still available and supported in the current release, but will be removed in a future release. Consider using SQL Server 2022 or later.

Network Atlas

Network Atlas is deprecated as of Orion Platform 2020.2. It is still available and supported in the current release, but will be removed in a future release. Deprecation is an indication that you should avoid expanded use of this feature and formulate a plan to discontinue using the feature. SolarWinds recommends that you start using Intelligent Maps in the SolarWinds Platform Web Console to display maps of physical and logical relationships between entities monitored by the SolarWinds Platform products you have installed.

Starting with 2024.2, you can import Network Atlas maps to Intelligent Maps. See Import maps.
