Migration guides

What changes between versions, and what to do about it in a pipeline you already have.

Moving to 0.9

0.9 is the first public beta. There is nothing to migrate from, but there is something to know about migrating away from it: the pipeline file format is not frozen yet.

• Record the version you ran, from Help then About.
• Archive the pipeline file next to your data.
• If a later version cannot open a file, the release notes will say so and what to do.

The policy from 1.0

From 1.0, a pipeline saved on any 1.x version will open on any later 1.x version. Card parameters may be added, never removed or renamed within a major version. A card that must change incompatibly gets a new identifier and the old one is marked deprecated, with the replacement linked from its marketplace page.
