- crun: add a new command crun mounts to dynamically add or remove mounts from a running container.
- linux: add support for moving existing network devices into the container namespace as defined in the OCI specification.
- linux: add src-nofollow and dest-nofollow mount options for more precise control over how symbolic links are handled.
- krun: implement support for external kernels, allowing users to bundle a kernel image with the container.
- krun: the vCPU limit has been increased to 16.
- krun: add support for specifying the libkrun flavor via the KRUN_VM_FILE.
- criu: fix checkpoint and restore for containers that have a bind mount where the destination is a symbolic link.
- criu: automatically create the directory specified by --work-path if it does not exist, improving compatibility with other runtimes.
- criu: re-enable support on the riscv64 architecture.
- cgroup: fix incorrect setting of cpu.max when the OCI quota is -1.
- hardening: replace all uses of the insecure sprintf function with safer alternatives like snprintf to prevent buffer overflows.
- fix a regression that caused issues when dealing with paths that do not exist and openat2 is not available.
- fix an issue where the file descriptor for the rootfs would become stale if the rootfs was replaced by a mount.
- fix parsing of rootless options.
- fix a potential crash in krun by checking if library handles exist before being unloaded.
- improve error messages for dlopen failures, making them more descriptive.
- cgroup: fix a regression on WSL when running with cgroup v1.
- libcrun: setup /dev/console as a symlink to pty instead of bind mount when possible.
