 ### Fixes
 
+- (snapshots) Preserve subdirectory structure in snapshot manifest keys instead of flattening to bare filenames ([#3269](https://github.com/getsentry/sentry-cli/pull/3269))
 - Replace `eprintln!` with `log::info!` for progress bar completion messages when the progress bar is disabled (e.g. in CI). This avoids spurious stderr output that some CI systems treat as errors ([#3223](https://github.com/getsentry/sentry-cli/pull/3223)).
