Tutorial: API changes between DNF and DNF5

The following sections describe the most common use cases and point out the main differences. DNF4 uses the libdnf library written in C++, but a lot of functionality exists only in Python, so, the examples cover only the Python API for DNF4.

The section Other notable changes on the API covers more detailed changes.

• 1. Changes in setting up the Base
• 2. Changes in loading repositories
• 3. Changes in creating queries
• 4. Changes in resolving dependencies and running a transaction
