# Release Notes for Nuke and Hiero 11.0v3

# Release Date

09 November 2017

# Qualified Operating Systems

• Mac OS X El Capitan (10.11) or macOS Sierra (10.12)

• Windows 7 or Windows 10 (64-bit)

• CentOS 6 or CentOS 7 (64-bit)

Note: If you intend to use floating licenses with Nuke 11, you'll need to upgrade the version of RLM used in the Foundry Licensing Tools (FLT) on your server. See Foundry Knowledge Base article Q100320 for information.

Other operating systems may work, but have not been fully tested.

## Requirements for Nuke's GPU Acceleration

If you want to enable Nuke to calculate certain nodes using the GPU, there are some additional requirements.

#### NVIDIA

An NVIDIA GPU with compute capability 2.0 (Fermi) or above. A list of the compute capabilities of NVIDIA GPUs is available at www.nvidia.co.uk/object/cuda_gpus_uk.html.

Note: The compute capability is a property of the GPU hardware and can't be altered by a software update.

With graphics drivers capable of running CUDA 8.0 & 6.5 or above.

• On Windows and Linux, CUDA graphics drivers are bundled with the regular drivers for your NVIDIA GPU. Driver version r361 or above is required.

Go to http://www.nvidia.com/Download/Find.aspx?lang=en-us for more information.

• On Mac, the CUDA driver is separate from the NVIDIA graphics driver and must be installed, if you don't have it already. The minimum requirement is driver version r361 which can be downloaded from www.nvidia.com/drivers.

Note: We recommend using the latest graphics drivers, where possible, regardless of operating system.

#### AMD

• On Windows and Linux, an AMD GPU and driver from the following list:

Windows GPU | Driver | Linux GPU | Driver
--- | --- | --- | ---
AMD FirePro W8100 | 17.Q2.1 | AMD FirePro W8100 | 17.Q2.1
AMD FirePro W9100 | 17.Q2.1 | AMD FirePro W9100 | 17.Q2.1
AMD Radeon R9 Fury X | 17.4.3 - 17.6.2 | AMD Radeon R9 Fury X | 17.10
AMD Radeon RX 480 | 17.Q2.1 | AMD Radeon RX 480 | 17.Q2.1
AMD Radeon Pro WX 7100 | 17.4.3 - 17.6.2 | AMD Radeon Pro WX 7100 | 17.10

Note: Other AMD GPUs may work, but have not been fully tested.

• On Mac an AMD FirePro GPU on late 2013 Mac Pro 6,1, mid 2015 MacBook Pro 11,5, and late 2016 MacBook Pro 13,3, running OS X 10.9.3 'Mavericks', or later.

#### Multi-GPU Processing

Nuke's GPU support includes an Enable multi-GPU support option. When enabled in the preferences, GPU processing is shared between the available GPUs for extra processing speed.

Note: Multi-GPU processing is only available for identical GPUs in the same machine. For example, two NVIDIA GeForce GTX 1080s or two AMD FirePro W9100s.

# New Features

There are no new features in this release.

# Feature Enhancements

• ID 143006 - DeepExpression: Nuke's Deep compositing nodes now support most of the math expression supported by regular nodes. See Nuke's Online Help for more information.

• ID 282546/306265 - Frame Server: Nuke's Preferences now include a frame server render timeout control, which allows you to increase the number of minutes a render process can stay unresponsive before ending. If you're experiencing Render application timed out messages with process-heavy scripts, you can try increasing this value.

• ID 304994 - macOS only: Using the Cmd+A keyboard shortcut to Select All in the Dope Sheet or Curve Editor selected all the nodes in the Node Graph.

• ID 305416 - macOS only: Enabling GPU acceleration in a Denoise node on machines with multiple GPUs caused Nuke to crash.

• ID 305898 - Timeline Disk Caching: Changes to edits were discarded when the root directory was changed and then restored to the default directory.

# Developer Notes

Here are the changes relevant to developers. See Help > Documentation from the Nuke menu bar or www.thefoundry.co.uk/products/nuke/developers/110/ndkdevguide/appendixc/index.html for more information.

As Nuke develops, we sometimes have to make changes to the API and ABI under the hood. We try to keep these changes to a minimum and only for certain releases, but from time to time API and ABI compatibility is not guaranteed. See the following table for the situations when you may have to recompile your plugins and/or make changes to the source code.

Release Type | Example | Compatibility | Recompile | Rewrite
--- | --- | --- | --- | ---
Version | 10.0v1 to 10.0v2 | API and ABI |  |
Point | 10.0v1 to 10.5v1 | API |  |
Major | 10.0v1 to 11.0v1 | - |  |

Additionally, node Class() names occasionally change between major releases. While these changes do not affect legacy scripts, you may not get the results you were expecting if a node class has been modified. The toolbars.py file, used to create Nuke's node toolbar, contains all the current node class names and is located in <install_directory>/plugins/nukescripts/ for reference.
As an example, between Nuke 9 and Nuke 10, the CameraShake node Class() changed from CameraShake2 to CameraShake3. In the toolbars.py file for the two releases, the entries for the CameraShake node appear as follows:
m.addCommand("CameraShake", "nuke.createNode(\"CameraShake2\")", icon="CameraShake.png")
m.addCommand("CameraShake", "nuke.createNode(\"CameraShake3\")", icon="CameraShake.png")

## Bug Fixes

• ID 238647 - Python: urllib2.py displayed SSL errors when looking for an expired link.

• ID 308316 - macOS only: Assigning the Ctrl or Cmd keyboard shortcut to the nuke.createNode() command for nodes in the toolbar replaced the selected node, rather than appending the new node.

• ID 316332 - Python: LiveGroups could not be published if they employed the filnameFilter function as a Callback between different operating systems.
