+The multi-project `show` command now displays changelog entries in chronological order, with the newest entry at the bottom of the table where users expect it. Previously, entries were sorted newest-first, which was inconsistent with single-project behavior and user expectations. This brings the multi-project display in line with the rest of the application's sorting behavior.
