Versioning and compatibility policy

Saved state and presets¶

• Every state or preset format written by RAVET carries an explicit format version.
• A newer release reads state written by any earlier release from 0.1.0 onward, for formats of implemented features. Older releases need not read newer state, and must reject it rather than misread it.
• prototype formats may change between minor releases. They still reject versions they do not understand, and never silently reinterpret them.
• Products that must read state written by other frameworks supply import hooks. RAVET does not guess at foreign formats.
