Note

This release contains breaking changes in the configuration file
syntax for DHCP clients. Specifically DHCP options with value,
i.e., the syntax for sending a hexadecimal value now require hex
prefix before a string of colon-separated pairs of hex values.

• Upgrade Buildroot to 2024.02.10 (LTS)
• Upgrade FRR from 9.1.2 to 9.1.3
• Add support for configuring SSH server, issue Add support for ietf-ssh-server YANG #441. As a result,
  both SSH and NETCONF now use the same host key in factory-config
• Add operational support for reading DNS resolver info, issue Operational status support for DNS and NTP #510
• Add operational support for NTP client, issue Operational status support for DNS and NTP #510
• Add support for more mDNS settings: allow/deny interfaces, acting
  as "reflector" and filtering of reflected services. Issue mdns: expose more Avahi configuration settings #678
• Add DHCPv4 server support, multiple subnets with static hosts and
  DHCP options on global, subnet, or host level, issue Basic DHCP server support #703.

  • DHCP client options aligned with DHCP server, startup-config
    files with old syntax are automatically migrated
• Breaking change in DHCP client options with value. Hexadecimal
  values must now be formatted as { "hex": "c0:ff:ee" } (JSON)
• Add documentation on management via SSH, Web (RESTCONF, Web
  Console), and Console Port, issue Document console settings #787
• Add documentation of DNS client use and configuration, issue Document DNS client use and configuration #798
• Add support for changing boot order for the system with an RPC,
  including support for reading boot order from operational datastore
• Add support for GRE/GRETAP tunnels
• Add support for STP/RSTP on bridges
• Add support for VXLAN tunnels

Fixes

• Fix Authorized SSH key not applied to startup config #777: Authorized SSH key not applied to startup-config
• Fix Review sysctl settings #829: Avahi (mDNS responder) not starting properly on switches
  with many ports (>10). This led to a review of sysctl:
  • New for IPv4:
    • Adjust IGMP max memberships: 20 -> 1000
    • Use neighbor information on nexthop selection
    • Use inbound interface address on ICMP errors
    • Ignore routes with link down
    • Disable rp_filter
    • ARP settings have been changed to better fit routers, i.e.,
      systems with multiple interfaces:
      • Always use best local address when sending ARP
      • Only reply to ARP if target IP is on the inbound interface
      • Generate ARP requests when device is brought up or HW address changes
  • New for IPv6:
    • Keep static global addresses on link down
    • Ignore routes with link down
• Fix A lot of reconfigurations cause confd to crash #861: Fix error when running 251+ reconfigurations in test-mode
• Fix Removing a port from a VLAN filtering bridge is broken #869: Setup of bridges is now more robust

One of the really sweet features of this release is RSTP! We all know what Radia Perlman thinks of it, but it's a stapleware of networking, and we can set it to run in its plain STP mode ☺️

Personally I worked on integrating the DHCP server from one of our partners, @minexn. It's the first step to where we want to go and yet it's going to be sufficient enough for most use-cases.

As always, please let us know if you find bugs or have feature requests. Whatever your needs, we can probably help you.
