0.60.2.0

Features

UVSampler : Added a new node sampling primitive variables from specific UV positions on a source object.
Saturation : Added a new node to adjust image saturation. This could previously be done using the CDL node, but using a specific node is sometimes clearer.

Render : In addition to the compute cache, the hash cache is now cleared prior to rendering.
Spreadsheet : Added interim support for adding a Spreadsheet::RowsPlug to a custom node. The previous doubling up of columns on reload can now be avoided by registering False for the new spreadsheet:columnsNeedSerialisation metadata item.

Viewer : Fixed bug which prevented the “Expand Selection Fully” operation from working.
Timeline : Fixed errors when the end frame is the same as the start frame (#4294).
GafferUI : Fixed edge artifacts when rendering transparent icons.
Render : Added workaround for hangs caused by specific chains of Expressions being evaluated after completion of the render.
NodeEditor : Fixed Internal C++ object already deleted errors in Python 3 builds.
Merge : Fixed failure to update when only the dataWindow of an input changed.
