Service eligibility and regional restrictions
PuppyIP serves only compliant overseas businesses and their authorized personnel. Proxy services are not available in mainland China. The service may only be used for lawful business activities outside mainland China. Use of this service within mainland China is prohibited.
Hosting a proxy IP or server overseas does not change these restrictions. The service must not be provided to end users in mainland China through relaying, forwarding, sharing or resale. Before use, read the Terms of Service.
Key Takeaways
- AWS released DCV 2026.0 on October 13, with server build 24952 and new Wayland support for RHEL 10, Rocky Linux 10, CentOS 10 and Ubuntu 26.04.
- The new native Mac client replaces the previous client and requires macOS 14 Sonoma or later. The Windows client requires Microsoft Visual C++ Redistributable 14.50 or later. Amazon Linux 2 support is discontinued.
- Windows hosts can redirect configured links from a remote session to the local client browser. Printer preferences redirection applies from a Windows client to a Windows host.
- Linux and Mac clients gain multithreaded H.264 slice software decoding. DCV EC2 licensing in the European Sovereign Cloud and macOS 27 server support on EC2 Mac have specific scopes; they do not make every deployment free or every connection faster.
Start with the remote host and the local client
AWS announced Amazon DCV 2026.0 availability on October 13, 2026. DCV is a remote display protocol: applications run on a remote host, while a client on your device presents the desktop or application session. Both sides have requirements. Adding support for a host operating system does not remove the local client's own requirements.
Three changes matter early in an upgrade decision. The new native Mac client requires macOS 14 Sonoma or later. The Windows client requires Microsoft Visual C++ Redistributable 14.50 or later, identified in the release notes as Visual Studio 2026. Amazon Linux 2 support has been discontinued. Map each condition to the relevant device before reviewing the new features.
For a hypothetical, untested example, an employee uses macOS 13 to connect to an Amazon Linux 2 remote desktop. That upgrade plan has two separate operating systems to address. Replacing a client with the 2026.0 version does not put both devices within support. Whether an existing environment still runs and whether the new release supports it are different questions.
Check Mac and Windows prerequisites before choosing a package
Mac users should first check their local macOS version. DCV 2026.0 introduces a new native Mac client that replaces the previous client and requires macOS 14 Sonoma or newer. On an older system, evaluate the operating system upgrade and your organization's software requirements first. A server upgrade does not establish that the new client can be installed.
Windows users and administrators should check the required runtime. The release notes specify Microsoft Visual C++ Redistributable version 14.50 or later, with Visual Studio 2026 in parentheses. The prerequisite is the redistributable runtime; it should not be read as a requirement for every connecting user to install the complete Visual Studio development environment.
Then check the build numbers by component. This release lists nice-dcv-server as 24952, the Windows client as 13455, the Mac and Linux viewers as 14405, and the web viewer as 24952. Different component build numbers are normal in these release notes. Do not choose a package merely to make the numbers match, or use the differences to assume compatibility across releases.
New Linux and Wayland support comes with an older OS departure
The release notes add Wayland support for RHEL 10, Rocky Linux 10, CentOS 10 and Ubuntu 26.04 virtual sessions. Wayland is a Linux graphical display system. The relevant scope is a supported environment for remote graphical sessions, rather than blanket support for every Linux distribution or session type.
Amazon Linux 2 support is discontinued at the same time. If a remote host still uses it, establish the supported replacement environment and application requirements before planning the DCV version change. Support for newer operating systems does not imply that the older system remains supported.
Record the distribution name, major version and session type together, then compare them with the current official release notes. Do not turn Ubuntu 26.04 virtual-session support into a claim about any physical console or desktop configuration. The announcement and release notes are also distinct from a complete installation or migration manual.
A link in the remote session can open your local browser
DCV 2026.0 adds URL redirection on Windows hosts. The announcement says configured links opened in a remote session can launch in the local browser on the client device. When deciding where a link opens, distinguish the remote browser from the local browser. Seeing the same page does not make the location of the request the same.
This is a configured redirection capability, rather than a promise that every link moves automatically. It does not change a website's eligibility, login permissions or regional rules. The two release sources reviewed here do not provide the complete setup procedure or allowed-link configuration. Consult the relevant official administration instructions before deploying it instead of guessing parameters from the announcement.
Printer preferences redirection also has a specific direction: a Windows client to a Windows host, giving the remote session access to client-side printer settings. The Mac client adds gamepad support, the Windows and Mac full-screen toolbars gain a minimize button, and the Linux client has a renewed user experience. Check each feature against its own platform scope.
Keep decoding improvements and EC2 support in their own scopes
This release adds H.264 frame slice support, which processes a video frame in portions. The Linux and Mac clients support multithreaded slice software decoding. AWS connects this improvement with lower latency in the announcement, but does not guarantee a particular improvement for every device, network or workload.
On the server side, the release notes add macOS 27 support on Amazon EC2 Mac instances. That is a remote Mac host requirement and capability. The local Mac client's minimum of macOS 14 is a separate condition; together they do not mean that every Mac must be upgraded to macOS 27.
The release notes also add DCV EC2 licensing support in the AWS European Sovereign Cloud. This named AWS environment should not be generalized to any European deployment or every cloud host. The sources do not establish on-premises pricing, specific charges or a universal free-use claim. Check the applicable license and resource costs for the environment you choose.
Use a checklist for both ends to decide the upgrade scope
First, list the remote host's operating system, DCV components and session type. Separately list the client platforms and operating systems used by connecting users. Record the server, Windows client, Mac or Linux viewer and web viewer as distinct components, instead of using one version label for the entire setup.
Next, compare the compatibility boundaries: macOS 14 for the new Mac client, Visual C++ Redistributable 14.50 for the Windows client, discontinued Amazon Linux 2 support, and the new Linux and Wayland session scopes. Resolve prerequisites that block use before deciding which components to update.
Finally, choose the features that serve the actual workflow. Opening remote Windows links locally, bringing Windows printer preferences into a session, and using the new Linux or Mac decoding capability are separate checks. Retain existing configuration and your organization's recovery plan before upgrading, and follow the relevant component instructions. A release announcement does not replace a connection and feature check in the applicable environment.

Frequently Asked Questions
Do I need macOS 14 if I connect through a browser?
The macOS 14 minimum in this release applies to the new native Mac client. Do not apply that condition automatically to every browser connection, or assume that any browser on an older Mac remains supported. Check the browser client's own complete requirements separately.
Does the Windows prerequisite mean installing all of Visual Studio 2026?
The release notes require Microsoft Visual C++ Redistributable 14.50 or later and identify it with Visual Studio 2026. The redistributable runtime and the complete IDE are different products. Have the administrator check the required runtime instead of treating development tools as a connection prerequisite for every user.
Will H.264 slice decoding speed up proxy traffic or file downloads?
This improvement concerns video decoding for DCV remote display. The release notes place multithreaded software decoding on Linux and Mac clients. It is not a general proxy, DNS or network-transfer acceleration promise; session latency still depends on the applicable device, network and workload.
Does European Sovereign Cloud licensing make DCV free on all European servers?
No such conclusion follows from the release notes. They describe DCV EC2 licensing support in the AWS European Sovereign Cloud, rather than a universal free license for European hosts or on-premises deployments. Confirm licensing, deployment eligibility and resource costs for the specific environment.
