#### API
41+
42+
- `GET /images/json` with the `manifests` option enabled now preserves the original order in which manifests appeared in the manifest-index. [moby/moby#48712](https://github.com/moby/moby/pull/48712)
43+
44+
#### Bug fixes and enhancements
45+
46+
- When reading logs with the `jsonfile` or `local` log drivers, any errors while trying to read or parse underlying log files will cause the rest of the file to be skipped and move to the next log file (if one exists) rather than returning an error to the client and closing the stream. The errors are viewable in the Docker Daemon logs and exported to traces when tracing is configured. [moby/moby#48842](https://github.com/moby/moby/pull/48842)
47+
- When reading log files, compressed log files are now only decompressed when needed rather than decompressing all files before starting the log stream. [moby/moby#48842](https://github.com/moby/moby/pull/48842)
48+
- Fix an issue that meant published ports from one container on a bridge network were not accessible from another container on the same network with `userland-proxy` disabled, if the kernel's `br_netfilter` module was not loaded and enabled. The daemon will now attempt to load the module and enable `bridge-nf-call-iptables` or `bridge-nf-call-ip6tables` when creating a network with the userland proxy disabled. [moby/moby#48685](https://github.com/moby/moby/pull/48685)
49+
- Fix loading of `bridge` and `br_netfilter` kernel modules. [moby/moby#48966](https://github.com/moby/moby/pull/48966)
50+
- containerd image store: Fix Docker daemon failing to fully start with a "context deadline exceeded error" with containerd snapshotter and many builds/images. [moby/moby#48954](https://github.com/moby/moby/pull/48954)
51+
- containerd image store: Fix partially pulled images not being garbage-collected. [moby#48910](https://github.com/moby/moby/pull/48910), [moby/moby#48957](https://github.com/moby/moby/pull/48957)
52+
- containerd image store: Fix `docker image inspect` outputting duplicate references in `RepoDigests`. [moby/moby#48785](https://github.com/moby/moby/pull/48785)
53+
- containerd image store: Fix not being able to connect to some insecure registries in cases where the HTTPS request failed due to a non-TLS related error. [moby/moby#48758](https://github.com/moby/moby/pull/48758)
54+
- containerd image store: Remove a confusing warning log when tagging a non-dangling image. [moby/moby#49010](https://github.com/moby/moby/pull/49010)
55+
- containerd image store: Do not underline names in `docker image ls --tree`. [docker/cli#5519](https://github.com/docker/cli/pull/5519)
56+
- containerd image store: Change name of `USED` column in `docker image ls --tree` to `IN USE`. [docker/cli#5518](https://github.com/docker/cli/pull/5518)

58+
- Disable IPv6 Duplicate Address Detection (DAD) for addresses assigned to the bridges belonging to bridge networks. [moby/moby#48684](https://github.com/moby/moby/pull/48684)

62+
- Fix anonymous volumes being created through the `--mount` option not being marked as anonymous. [moby/moby#48755](https://github.com/moby/moby/pull/48755)
63+
- After a daemon restart with live-restore, ensure an iptables jump to the `DOCKER-USER` chain is placed before other rules. [moby/moby#48714](https://github.com/moby/moby/pull/48714)
