This is the first time-based released for containerd. Most the feature set and core functionality has long been stable and harderened in production environments, so now we transition to a balance of timely delivery of new functionality with the same high confidence in stability and performance. * Add no_sync option to boost boltDB performance on ephemeral environments ([containerd#10745](containerd#10745)) * Add content create event ([containerd#11006](containerd#11006)) * Erofs snapshotter and differ ([containerd#10705](containerd#10705)) * Update CRI to use transfer service for image pull by default ([containerd#8515](containerd#8515)) * Support multiple cni plugin bin dirs ([containerd#11311](containerd#11311)) * Support container restore through CRI/Kubernetes ([containerd#10365](containerd#10365)) * Add OCI/Image Volume Source support ([containerd#10579](containerd#10579)) * Enable Writable cgroups for unprivileged containers ([containerd#11131](containerd#11131)) * Fix recursive RLock() mutex acquisition ([containerd/go-cni#126](containerd/go-cni#126)) * Support CNI STATUS Verb ([containerd/go-cni#123](containerd/go-cni#123)) * Retry last registry host on 50x responses ([containerd#11484](containerd#11484)) * Multipart layer fetch ([containerd#10177](containerd#10177)) * Enable HTTP debug and trace for transfer based puller ([containerd#10762](containerd#10762)) * Add support for unpacking custom media types ([containerd#11744](containerd#11744)) * Add dial timeout field to hosts toml configuration ([containerd#11106](containerd#11106)) * Expose Pod assigned IPs to NRI plugins ([containerd#10921](containerd#10921)) * Support multiple uid/gid mappings ([containerd#10722](containerd#10722)) * Fix race between serve and immediate shutdown on the server ([containerd/ttrpc#175](containerd/ttrpc#175)) * Update FreeBSD defaults and re-organize platform defaults ([containerd#11017](containerd#11017)) * Postpone cri config deprecations to v2.2 ([containerd#11684](containerd#11684)) * Remove deprecated dynamic library plugins ([containerd#11683](containerd#11683)) * Remove the support for Schema 1 images ([containerd#11681](containerd#11681)) Please try out the release binaries and report any issues at https://github.com/containerd/containerd/issues. * Derek McGowan * Phil Estes * Akihiro Suda * Maksym Pavlenko * Jin Dong * Wei Fu * Sebastiaan van Stijn * Samuel Karp * Mike Brown * Adrien Delorme * Austin Vazquez * Akhil Mohan * Kazuyoshi Kato * Henry Wang * Gao Xiang * ningmingxiao * Krisztian Litkey * Yang Yang * Archit Kulkarni * Chris Henzie * Iceber Gu * Alexey Lunev * Antonio Ojea * Davanum Srinivas * Marat Radchenko * Michael Zappa * Paweł Gronowski * Rodrigo Campos * Alberto Garcia Hierro * Amit Barve * Andrey Smirnov * Divya * Etienne Champetier * Kirtana Ashok * Philip Laine * QiPing Wan * fengwei0328 * zounengren * Adrian Reber * Alfred Wingate * Amal Thundiyil * Athos Ribeiro * Brian Goff * Cesar Talledo * ChengyuZhu6 * Chongyi Zheng * Craig Ingram * Danny Canter * David Son * Fupan Li * HirazawaUi * Jing Xu * Jonathan A.

Dynamically linked with glibc 2.35 (Ubuntu 22.04). * `containerd-static-<VERSION>-<OS>-<ARCH>.tar.gz`: Statically linked. Expected to be used on Linux distributions that do not use glibc >= 2.35. Not position-independent. In addition to containerd, typically you will have to install [runc](https://github.com/opencontainers/runc/releases) and [CNI plugins](https://github.com/containernetworking/plugins/releases) from their official sites too.

The snapshotter and differ are fully plug-able today, however experimentation can be limited by the media types supported by unpack. This change allows specifying the config and layer media types to use for a platform unpack configuration alongside the snapshotter and differ.
Experimentation for new types is still limited to using the platform and rootfs keys defined by OCI. Anything beyond that would need something much different than the current unpacker anyway. This adds stricter checks for the rootfs field type when unpacking an OCI image. OCI requires this value to be set to "layers", however we should also consider an empty value the same as layers to avoid breaking. Any non-"layers" value can be used for experimentation though.
