 ## [Unreleased]
 
+## [0.9.1] - 2024-12-22
+### Fixed
+- **Critical**: Fixed ext4 filesystem corruption in `SHRINK` command caused by resizing mounted filesystems.
+  - The filesystem is now properly unmounted before resize operations.
+  - Moved `SHRINK` to new stage 50-finalize that runs after chroot teardown for cleaner separation.
+
+### Changed
+- Improved code architecture by introducing stage 50-finalize for image-level operations.
+  - Stage 40-postprocess now only handles operations requiring active chroot (PUMP, ZERO).
+  - Stage 50-finalize handles operations on unmounted images (SHRINK).

 This allows for better compression of the resulting image, resulting in smaller image files.
 Useful when creating images for distribution.
 
+#### 5. Finalize Stage
 ##### `SHRINK [SIZE]`
 `SHRINK` reduces the image file size by shrinking the filesystem and partition.
 The operation performs a filesystem check, resizes the filesystem, updates the partition table, and truncates the image file.
