The Uplynk Slicer family of applications runs on select Linux, MacOS, and Windows hosts in customer-managed deployments. The Slicer applications are required to perform certain communications tasks with the Uplynk Cloud infrastructure, such as logging in and reporting status.
Since the slicer's very early days, we have bundled Root Certificate Authority Certificates with the application to manage our TLS/SSL trust chain. In the June 2023 release, we upgraded the bundled Root CA Certificates to align with our cloud hosting platform requirements.
The Uplynk Cloud infrastructure provides TLS certificate security based on a certificate signed by a trusted Root CA. Slicer versions released prior to June 2023 do not contain the updated Root CA certificate required for validating future TLS certificates. As a result, these versions must be updated to maintain connectivity and functionality.
Starting August 1, 2025, the cloud management system will only support slicers released in June 2023 or later. Slicers older than this date will log an error message stating that they do not meet the system’s minimum requirements, and content will not be processed. To resume content processing, the slicer must be updated. This change does not impact VoD or linear content already processed and stored in the library using older versions.
Even if your slicers are inactive, we recommend reviewing your live and VoD slicer versions and upgrading any version dated before June 2023. Please ensure any inactive workflows are prepared to go live when needed. You will also see a CMS news item confirming this message.
If you need to upgrade your slicers, we strongly recommend using the most recent slicer version. We also advise testing in a staging environment to ensure workflow compatibility.

If you are running Python 2.0 plugins (used for SCTE ad marker detection), do not upgrade beyond version 23062600. Slicers released after that version only support Python 3.0 or later. While not required, we recommend rewriting any Python 2.0 plugins in a current version of Python and using them on the latest supported Slicer version.

Launched four years ago, the CSL V1 platform was our first CMS-integrated live-streaming solution via hosted slicer ingest into Uplynk. Many customers now deliver high-quality encoded source streams to Uplynk using newer protocols like SRT—and have successfully leveraged CSL V1. Conceptually, the platform established ingest points (URL’s and expected protocols) that could be streamed to. When a new cloud slicer was created, it would effectively be linked to the ingest point as part of that process.
Over the past six months, our development team has built a new version of the platform—CSL V2—with a re-architected design to improve scalability, reliability, cost-efficiency, and launch speed. From a usage perspective, we eliminated ingest points being separate from the slicer. Instead of deleting a slicer to free up the resource when not being used, we implemented a stop and start capability in CSL V2.
Due to the architectural differences, CSL V1 slicers cannot be directly migrated to V2. Existing V1 endpoints are not reusable, and customers must create new V2 slicers for their workflows.
You may pre-create the V2 slicer (with a different name/ID) before stopping the V1 slicer. Once ready, simply point the source stream to the new V2 slicer and add it to your desired channel or event.
If your channel cannot be interrupted, duplicate the feed, send a copy to a V2 slicer, configure a failover group, and then remove the V1 slicer.
Simply delete it. Should you require one in the future, use CSL V2. The CSL V2 User Guide offers step-by-step instructions:

You can now upload TS captures and other troubleshooting files directly through the new Support page in the Uplynk UI. Files are stored securely and automatically deleted after 14 days. Visit the Support section to get started.

When setting up a new ad server with "Universal Ad Configuration", you often receive an "Ad Tag" - a template URL from your ad provider that includes server information and required parameters. With this enhancement, you can simply paste your Ad Tag URL, and the system will automatically parse it and populate the configuration with all the relevant values. This makes setup faster, easier, and helps reduce the risk of manual errors.

The following update of the Dolby ID names in the Dash manifest only has changed as follows:
| Codecs | ID From | ID To | Notes |
|---|---|---|---|
| ec-3 | maindolby6 | mdolby6 | Dolby 5.1 Encoded Audio by the Slicer |
| ec3s | maindolby2 | mdolby2 | Dolby 2.0 Encoded Audio by the Slicer |
| ac-3 | maindolby_orig | mdolbyO | Dolby Pass-through mode |
| ac-3 | unddolby_orig | udolbyO | unDolby Pass-through mode |
The following is an example of this portion of a current Dash Manifest and change: Dolby 5.1 previous:
<Representation bandwidth="129741" codecs="ec-3" id="maindolby6">
Has changed to:
<Representation bandwidth="129741" codecs="ec-3" id="mdolby6">
The other Dolby codecs would change as the example above.

The original Slicer Failover (pre-2020) found under the Channels->Playback tab is being discontinued on about June 30, 2025. On that tab, the Enable Automatic Failover checkbox should be unchecked to work with the current Failover, introduced in 2020, which is under the Ingest tab.
The Slicer Failover going forward is described at https://docs.uplynk.com/docs/failover.

The Legacy 'Hosted Slicers' Cloud Slicer Live V1 platform will be shut down on June 30th, 2025. We recently launched our 'Cloud Slicers' Cloud Slicer Live (CSL) V2 platform. If you have any existing Hosted Cloud Slicers in the V1 environment, please create new ones in the V2 environment and move your streams to them. The CSL V2 offering brings improvements to resource management, failover handling, and usability. These updates make CSL lighter, more flexible, and cost-effective, ensuring a smoother workflow experience. CSL V2 also offers a simplified UI and adds the ability to Start and Stop slicers to keep costs down and simplify the business process

Uplynk has traditionally secured their APIs with a user-generated token that utilized API keys that are viewable in the Uplynk CMS. This technique is not very flexible, meaning that any API key generated by a user could access all Uplynk functionality, regardless of whether the user of the API key needs this access.
Scoped API Keys allows specific API functionality to be limited to those individuals or systems that need it. Uplynk's traditional API integration keys and the new Scoped API Keys will coexist for the foreseeable future.
Information on Scoped API Keys can be found at https://docs.uplynk.com/reference/scoped-api-keys.

The LVP Player has been updated for supporting audio-only playlists. For those who are unfamiliar with the LVP Player, it was originally the player for the now deprecated Limelight Video Platform but has been updated to work with Uplynk and supports Uplynk-specific functionality such as the ability to play VOD playlists.
For more information on the LVP Player, please refer to https://docs.uplynk.com/docs/lvp-player.
