+- Case-sensitive username filtering causing silent backup failures.
+  [Rodos]
+
+  GitHub's API accepts usernames in any case but returns canonical case.
+  The case-sensitive comparison in filter_repositories() filtered out all
+  repositories when user-provided case didn't match GitHub's canonical case.
+
+  Changed to case-insensitive comparison.
+
+  Fixes #198

+- Avoid rewriting unchanged JSON files for labels, milestones, releases,
+  hooks, followers, and following. [Rodos]
+
+  This change reduces unnecessary writes when backing up metadata that changes
+  infrequently. The implementation compares existing file content before writing
+  and skips the write if the content is identical, preserving file timestamps.
+
+  Key changes:
+  - Added json_dump_if_changed() helper that compares content before writing
+  - Uses atomic writes (temp file + rename) for all metadata files
+  - NOT applied to issues/pulls (they use incremental_by_files logic)
+  - Made log messages consistent and past tense ("Saved" instead of "Saving")
+  - Added informative logging showing skip counts
+
+  Fixes #133
