You can now export and import generator presets. During the import:

  • If the identifier of an imported preset matches an existing preset, the existing preset is updated.

  • If the identifier of an imported preset doesn’t match an existing preset, a new preset with that identifier is created.

Fixed upload of large JSON files based on a prefix filter so that they validate and upload properly. Also fixed some scenarios that could fail with JSON elements larger than 2GB.

Added the Text Composition generator, which allows you to configure the output value for a column as a template that incorporates values from other columns.
