package charrua-unix

v2.1.1 (2025-10-02)

• Log a warning when gateway but no cidr is passed to Dhcp_v4.Make.connect as that is not currently handled. (#138 @hannesm @reynir)
• Add a condition in Dhcp_client_lwt.connect in order to cancel the listener earlier when we have a successful lease. This ensures this listener doesn't "steal" packets from later installed listeners resulting in dropped packets for about four seconds. (#137 @reynir @hannesm)

v2.1.0 (2025-09-02)

• Add support for client FQDN (RFC 4702) (#133 @hannesm)
• Client: allow cidr, gateway, no_init being passed to connect. If passed, no DHCP requests will be done. This enables MirageOS unikernels where the decision whether to do DHCP or not is done at runtime (#135 @hannesm)
• Client: pass options to be embedded in the DHCP request (#135 @hannesm)
• server: extend Update and Reply with lease and DHCP options (#135 @hannesm)
