Upgrading
How to move Natsura to a new version, and what to do when a scene built in an older version needs bringing up to date.
Upgrading has two parts: installing the new version of Natsura, and bringing existing scenes up to date so they use the current nodes and defaults. Installing the new version follows the same steps as a first install (see Installation).
Scenes made in an older version keep working, but older nodes may need updating to pick up new behaviour and fixes. Natsura provides an upgrade path for this rather than leaving you to rewire by hand.
Detailed steps pending.
