  that interface has a MAC address defined. #553
- `wwctl container delete` now also deletes the built images
  associated with that container. #214
- Unified internal code paths for `wwctl profile` and `wwctl node`
  commands, and between the on disk YAML format and the in memory
  format, enabling the command-line options to be autogenerated from
  the datastructures and ensuring that profile and node capabilities
  remain in sync. Multiple command line arguments have been updated or
  changed. #495, #637
- `wwctl power` commands no longer separates node output with
  additional whitespace. #514

### Fixed

- `/etc/warewulf/excludes` (read from the node image) once again
  excludes files from being included in the node image. #532
- `wwctl ssh` always uses a node's primary interface. #544
- `wwctl container show` now correctly shows the kernel version. #542
- System users are no longer prevented from logging into compute
  nodes. #538
- `wwctl overlay chown` now correctly handles uid and gid arguments. #530
- `wwctl overlay chown` no longer sets gid to `0` when unspecified. #531
- Corrected the path for `.wwbackup` files in some situations. #524
- Bypass `imgextract` for legacy BIOS machines to avoid 32-bit memory
  limitations. #497
- `warewulfd` no longer panics when network interface tags are
  defined. #468
- The wwinit overlay now configures the network device type. #465
- Minor typographical fixes. #528, #519

## 4.3.0, 2022-06-25

### Added

- All configurations files for the host (/etc/exports, /etc/dhcpd.conf, /etc/hosts) are now
  populated from the (OVERLAYDIR/host/etc/{exports|dhcpd|hosts}.ww . Also other configuration
  files like prometheus.yml.ww or slurm.conf.ww which depend on the cluster nodes can be
  placed. Also the new templated functions {{ abort }}, {{ IncludeBlock }} abd {{ no_backup }}
  are allowed now.
- nodes and profiles can now have multiple system and runtime overlays, as a comma separated list.
  The overlays of the profile and the nodes are combined.
- simple ipv6 support is now enabled. In `warewulf.conf` the option `ipaddr6`/`Ipv6net` must
  be set to enable ipv6. If enabled on of these options is set a node will get a derived
  ipv6 in the scheme `ipv6net:ipaddr4`. This address can also be overwritten for every
  node
- Multiple files can now created from a single `template.ww` file with the `{{ file FILENAME }}`
  command in the template. The command is expanded to the magic template command
  `{{ /* file FILENAME */}}` which is picked up by wwctl and everything which comes after this
  magic comment will be written to the file `FILENAME`. This mechanism is leveraged in the
  configuration files for the network, see `ifcfg.xml.ww` and `ifcgf.ww`.
- Networks can now have arbitrary keys value pairs in the profiles and on the node, so that
  things like bridges and mtu sizes can be set
- oci container tar balls can be imported with the 'file://$PATH' scheme
- uids and gids of a container can now get synced at import time, so that at least users with the
  same name have the same uid. This is not necessarily needed for warewulf, but services like
  munge.

### Changed

- Provision interface is not tied to 'eth0' any more. The provision interface must be have the
  'primary' flag now. The file `nodes.conf' must be changed accordingly.
- the provisioning network is now called primary and not default
- Creating of '/etc/exports' can now be disabled, so that `wwctl configure -a` wont overwrite
  a existing '/etc/exports'.
- The yaml format for nodes has now sub-keys for ipmi and kernel, old nodes.conf files have to
  to be changed accordingly
- host overlays can globaly disbaled, but are enabled per default
- `wwctl overlay build -H` will only build the overlays which are assigned to the nodes

## 4.1.0, 2021-07-29

### Added

- Support for ARM nodes
- firewalld service file for warewulfd
- `-y` option to skip "Are you sure" queries
- `wwctl kernel delete` command
- `wwctl vnfs` alias for `wwctl container`
- Support for authenticated OCI registries
- warewulfd can reload config on SIGHUP and when the config file changes
- Node database index to improve lookup speeds
- Kernels and containers can be imported from a chroot subdirectory
- Systemd service file

### Changed

- `wwctl node list` output beautification
- Log timestamps are more precise
- PID file and log files are now in `/var/run` and `/var/log`, respectively
- `make install` no longer overwrites preexisting configuration files
- Kernel modules and overlays are now compressed
- `rootfstype` now uses `rootfs` in default kernel arguments
- iPXE binaries updated
- Installed container directory is deleted when import fails
- Default iPXE script now reboots erroring nodes every 15 seconds
- Only open `/etc/hosts` when writing

### Removed

- `wwctl configure` `--persist` flags have been removed. `configure` commands persist changes by default unless `--show` is used
- In-repository documentation: has been moved to it's own repository

### Fixed

- Importing containers from directory
- Debug log verbosity option takes precedence over verbose option
- `wwctl node list -n` output is formatted corectly
- Container names can contain an underscore
- `wwctl overlay build --all` does not require an argument
- specfile date format works with older versions of rpmbuild
- Use SystemOverlay when building system overlay
- dhcpd template now references correct wwctl subcommand
- `wwctl node set kernelargs` and `wwctl profile set kernelargs` change kernel arguments
