DNSFilter is a cloud-delivered service. To maintain security, compatibility, and reliable operation, all Roaming Client (RC) and Relay software must remain on supported versions. This document defines how DNSFilter determines version support, how End-of-Life (EOL) is handled, and what customers and partners should expect.
As part of the EOL policy, admins should follow basic standards:
- Maintain deployments on supported versions listed below
- Upgrade any EOL versions before contacting DNSFilter Support
- Expect Support to request upgrades to the latest release, as patches and fixes are only delivered there
- Notice is provided only for major deprecations, not for routine version retirements
Current Supported Versions
| Platform | Supported Agent Versions | EOL Agent Versions | Supported OS |
|---|---|---|---|
| Windows | 2.2.1 and newer | 2.0.10 and older | Windows 10 or newer with .NET Framework 4.8+; Server 2016 or newer (Relay only) |
| macOS | 1.8.6 and newer | 1.8.0 and older | Big Sur (11), Monterey (12), Ventura (13), Sonoma (14), Sequoia (15), Tahoe (26) |
| iOS | 1.0.8 and newer | 1.0.7 and older | iOS 17 or newer |
| Android | 1.19.0 and newer | 1.18.0 and older | Android 13 or newer |
| ChromeOS | 3.0 and newer | 2.4.1 and older | ChromeOS |
| DNS Relay | 1.2.0 and newer | 1.1.9 and older | N/A (no OS dependency) |
Support Levels
Supported Versions
- Eligible for diagnosis and troubleshooting by DNSFilter Support (best effort)
- Customers are expected to remain on supported versions to ensure continued protection
- All patches, bug fixes, and security updates are delivered only in the latest release
- Customers on supported but older versions may still be asked to upgrade as part of issue resolution
End-of-Life (EOL) Versions
- Not eligible for DNSFilter Support
- Must be upgraded to a supported version before assistance is provided
- Do not receive patches, bug fixes, or compatibility updates
Routine Lifecycle vs. Major Deprecations
Routine Version EOL
- Older versions are retired when they fall behind the minimum supported threshold
- No formal notice period is guaranteed
- Customers are expected to upgrade regularly
Major Deprecations
DNSFilter provides at least 60 days’ notice if:
- An entire platform (e.g. Android, ChromeOS) is discontinued, or
- A new dependency (e.g. .NET version) removes support for an OS still supported by its vendor
Notice is provided via email and in-product messaging.
Alignment With OS Vendor Schedules
- DNSFilter aligns support with operating system vendor lifecycles
- Example: When Microsoft ended support for Windows Server 2012, DNSFilter also ended support for RC/Relay on that OS
- In some cases, DNSFilter may EOL a client earlier if new dependencies require it
