{{Release|4.3}}
=== New features ===
* Memory compression: Support for LZ4 memory page and block compression with multi-threaded decompression
* Support for AArch64 / ARM64 Guarded Control Stack (GCS)
* Parallelize memfd and anonymous shared memory content restore via async daemon (asyncd)
* Restorer: Restore VMA pages with Linux native AIO
* Add --image-io-mode option to support O_DIRECT reads/writes for pages images
* plugins/amdgpu: Support checkpoint and restore of DRM buffer objects and DMA-BUF file descriptors
* Support for Linux kernel binfmt_misc sandboxing
* Add UPDATE_INETSK hook for socket address rewrite during restore
* crit: Add offline compress and decompress commands for memory images
* criu: Add collection and restoration of timer_slack_ns per thread
=== Bugfixes ===
* restore: Fix exit code and wait status truncation for zombie processes
* restorer/pagemap: Detect EOF on truncated pages file to prevent infinite loops
* file-lock: Fix type confusion in broken read lease restore
* soccr: Restore TCP_REPAIR_WINDOW before TCP_SEND_QUEUE to avoid window collapse
* sk-queue: Fix SCM restore for packets containing both SCM_RIGHTS and SCM_CREDENTIALS
* sk-unix: Fix mutex deadlock on connect failure in standalone restore
* pipes: Restore pipe ownership to fix /proc/self/fd access permissions
* compel: Fix heap alignment for structs with XSAVE state
* fsnotify: Fix memory and file descriptor leaks in inotify/fanotify error paths
* pycriu: Fix self-dump failure when explicit PID is provided
=== Improvements ===
* compel/infect: Optimize task interception and stop tasks without hardware breakpoints
* restorer: Switch thread synchronization to atomic operations
* restore: Parallelize task stopping in attach_to_tasks and catch_tasks
* fsnotify: Add overlayfs directory walk fallback for inotify watches
* sockets: Support dumping and restoring ucred for Unix and Netlink sockets
* coredump: Enable coredump generation on riscv64
* contrib: Add reference client and test suite for criu-service
* docs: Major overhaul and export of "Under the Hood" architecture documentation
* ci: Consolidate test workflows, shard test suites, and add Lima-based kernel test jobs
