+nilfs-utils-2.3.0  Sun Jan 25, 2026 JST
+
+	* New Features:
+	  - Support file/directory arguments for utilities (lscp, lssu,
+	    nilfs-clean, etc.) to automatically resolve backing devices.
+	  - nilfs-clean: Automatically adjust GC speed by default, eliminating
+	    manual tuning.
+
+	* GC Daemon (cleanerd) Improvements:
+	  - Cap segments per cleaning step by available free segments to
+	    prevent stalling when free space is running out.  Also, cap
+	    the number of segments per cleaning step to prevent theoretical
+	    size_t overflow on 32-bit systems.
+	  - Improve signal handling (exit cleanly on SIGINT, ignore SIGUSR2).
+	  - Add state dump feature (SIGUSR1).
+
+	* Build System Updates:
+	  - Support generating pkg-config information for shared libraries.
+	  - Support pkg-config for finding dependencies (libuuid, libmount,
+	    libblkid, libselinux).
+	  - Do not install static libraries by default.
+	  - Gather system programs directly below sbin source directory.
+
+	* Library Refactoring and API Changes:
+	  - Reorganize APIs in libnilfs and libnilfsgc:
+	    - Add/update APIs for segment I/O, resize, and freeze/thaw.
+	    - Unify type definitions (use standard uint32_t/uint64_t).
+	    - Remove obsolete APIs and internal structures from public headers.
+
+	* Other Utilities Updates:
+	  - mkfs.nilfs2: Set "block_count read-only compat" flag by default.
+          - Align help message output and exit codes with standard conventions
+	    (e.g. nilfs-tune).
+	  - nilfs-resize: Use new library API for layout information.
+
+	* Miscellaneous:
+	  - Refactor type definitions (use uint64_t/uint32_t/bool/size_t) for
+	    safety and consistency.
+	  - Adapt to Sparse code checking (fix endian macros, etc.).
+	  - Massive code cleanups and coding style fixes.
+
+	* Note: Although the development tree diverged from v2.2.5, updates
+	  in the v2.2.y stable branch are backports derived from the master
+	  branch.  Consequently, this release incorporates all fixes and
+	  improvements listed below from nilfs-utils-2.2.6 through
+	  nilfs-utils-2.2.16.
+
