About the release
The 15.0.0 release is the third of our 2026 releases. Please see below for the highlights, along with the full list of fixes and improvements. As always, we look forward to your feedback as we continue to improve the product every single month.
The Datto RMM team is reaffirming its commitment to delivering important updates more frequently through officially recognized interim releases. These releases will typically include urgent bug fixes or minor enhancements and will not require scheduled maintenance windows. Details of the updates since the previous full release will be included in Updates since this release.
Web Remote reliability improvements
This release improves the reliability of Web Remote connections by introducing DNS fallback mechanisms and enhanced DNS analytics logging in both the Datto RMM Agent and the Web Remote component. These changes directly reduce initial connection failures caused by DNS resolution issues on target devices, supporting a more reliable remote desktop experience for technicians.
Key features
- DNS fallback is implemented in both the Datto RMM Agent and Web Remote component communications channels on the target device.
- On DNS resolution failure, the system first attempts to use the device’s configured DNS, then automatically retries with a set of known good public DNS servers.
License and billing updates
Variable usage reminders
Administrators now receive updated in-product reminders to review variable license usage ahead of month-end billing calculations.
- Informational banners now appear as month end approaches, helping administrators review variable license usage and avoid unexpected charges.
- Each banner includes quick access to related licenses and notification settings.
- Notifications are shown only when variable usage is greater than zero.
Activation and deactivation controls
Advanced Software Management and Ransomware Detection can now be activated and deactivated directly from the Licenses page.
- Activation now requires an explicit acknowledgment of inclusion in variable billing calculations.
- When usage reaches zero, you can deactivate a feature and re-enable it later if needed.
- License cards include links to learn more about each feature before you decide whether to activate it.
Policy-level usage details
Policy-level visibility into Advanced Software Management and Ransomware Detection license usage is now available from the Licenses page.
- Use View Details to see which policies are contributing to license consumption.
- Review per-policy device counts to understand what is driving usage.
- Open related policies directly to review and adjust configuration.
Device page improvements
The Column Chooser for device list pages has been redesigned for quicker, easier navigation. You can now search columns by name, drag and drop to reorder columns, use Shift+Click to select multiple items, and filter by category, making it much easier to manage custom views, even with 300 UDFs.
Software Management compliance status sync improvements
This release introduces improvements to the Software Management and Advanced Software Management cache settings, fixing an issue where compliance statuses were not synced between the Datto RMM Agent and the platform, improving reliability of the software management status when viewing devices online.
Extended SNMPv3 protocol support
Network Discovery and Monitoring now support new SNMPv3 authentication and privacy protocols, improving compatibility with security-hardened devices.
Key improvements
- New authentication protocols: SHA-256, SHA-384, and SHA-512 are now available for SNMPv3 credentials alongside existing MD5 and SHA-1 options.
- New privacy (encryption) protocols: 3DES, AES-192, and AES-256 are now supported in addition to existing DES and AES-128.
Network Discovery page redesign
The Network Discovery page has been renamed to Network, reflecting its broader scope beyond discovery to include node and subnet configuration.
Key improvements
In addition to the page being renamed, a new Network Nodes tab has been added to the Network page. This is a dedicated tab for orchestrating network nodes (with multi-node support) and managing subnets. Notable new features on this page include:
- The ability to nominate eligible devices as network nodes (with configurable scanning status).
- View node details at a glance: device name, IP, subnets (CIDR), scanning status, assigned devices, and more.
- Unassign nodes with the option to reassign devices to another active node.
- Multi-node support per site for broader network discovery coverage.
- A dedicated Additional Subnets section for managing custom subnets per site in one location
- Add custom subnets in CIDR format with inline validation.
- Edit subnet CIDR and description inline.
- Delete custom subnets no longer needed.
- Overlapping subnets (auto-detected vs. custom) are allowed.
NOTE With this update, the Additional Subnets section will be removed from the Site Settings page, Create Site page, and the old Network Discovery wizard, consolidating all subnet management into the new Network Nodes tab.
NOTE As announced last release, going forward Additional Subnets will use CIDR notation (for example: 192.168.1.0/24) instead of the IP ranges format. CIDR is the modern industry standard for defining network ranges, as it is more precise, consistent with broader networking tools, and reduces the risk of misconfiguration.
NOTE All existing additional subnet entries will be automatically converted to CIDR format upon upgrade. No action is required on your end.
Variables: Security notice banner for sensitive data
When you work with variables across Datto RMM (in Global Settings, Components, Site Settings, Jobs, and Monitoring policies) you now see a security notice banner next to the Variables section. This helps you make informed decisions when using sensitive data within variables.
Additions to the ComStore
We release new ComStore components and update existing ones every month. Notable additions this month include the following:
- Get/Set Windows Hello Max/Min PIN Length [WIN]: Use this component to retrieve and set the Windows Hello PIN length.
- Windows Defender Configuration Tool [WIN]: Configure Windows Defender remotely with this component.
- User Toolkit [MAC][LIN]: Allows user creation, configuration, and deletion for *nix type systems.
NOTE To access a full list of ComStore components, refer to List of ComStore components.

Updates in this release
API
| Type | Summary |
|---|---|
| Foundation | The advanced search capabilities added in {{/v2/activity-logs}} allow you to narrow down results and find relevant log entries using field searches, wildcards, and boolean operators. The new searchQuery parameter supports the same search queries and syntax as a corresponding UI field, and allows it to carry out advanced querying of the Activity Log, reducing client-side filtering and fewer API calls for common use cases. |
Comstore
| Type | Summary |
|---|---|
| Fix | Email notifications for new and updated ComStore components are now delivered more reliably. |
Device management
| Type | Summary |
|---|---|

| Foundation | Scheduled jobs that are due to run are now picked up and started more efficiently, helping reduce delays during busy periods. |
| Foundation | Scheduled job status updates are now processed more efficiently, helping completed and expired jobs appear with less delay. |
| Foundation | Background job processing now scales more smoothly during periods of higher demand, helping maintain capacity for heavier job workloads. |
| Fix | The job results export now supports targeted devices with blank or missing descriptions. |
Kaseya Intelligence
| Type | Summary |

Previously, leaving this field blank would display a This field is required error, even though the field is optional. The behavior now matches the Setup > Credentials > Add Credentials UI, where the Context field can be left blank as expected. |
| Fix | Date ranges on license usage cards now display in ISO 8601 format to align with international standards. |
| Fix | Fixed an issue where bulk deleting a large number of devices (200+) displayed a false Delete devices failed error notification, even though all devices were deleted successfully. |
