+Your task is to prepare the next release:
+1. Analyze the recent changes in the codebase, using git commit messages and diffs.
+2. Identify significant features, bug fixes, and improvements.
+3. Write clear and concise release notes summarizing these changes, appending them in data/com.ranfdev.DistroShelf.metainfo.xml.in. Ensure you add the new release entry at the top of the releases section with the current date.
+4. Look at the version history in data/com.ranfdev.DistroShelf.metainfo.xml.in to determine the next version number, following semantic versioning principles.
+5. Update the version number in the root meson.build
+6. Do a final git commit with the message "vX.Y.Z". Finally, tag the commit with "vX.Y.Z".
