Stored Transaction JSON Format

The stored transaction format is considered unstable and may change in an incompatible way at any time. It will work if the same version of dnf is used to store and replay (or between versions as long as it stays the same).

Top-level Object

version

Type: string

The version of the stored transaction format, in the form MAJOR.MINOR.

MAJOR version denotes backwards incompatible changes (old dnf won’t work with new transaction JSON).

MINOR version denotes extending the format without breaking backwards compatibility (old dnf can work with new transaction JSON).
