I took a look at what both are doing and I had to add the ENUM numbers into RustCord for the new things to be captured. I'd like to suggest a collaboration on the two mods to make it more update friendly. I don't really know how to code but I think it the Death Notes hook needs to include one of the catgories that RustCord is splitting the notes into the RustCord permissions of plugin_deathnotes_pvp/animal/vehicle/npc. Then RustCord can use that to determine its logic instead of having to add all the ENUM numbers from the combatEntity Enum.

If anyone's interested, this is the change I made to RustCord to make it report the new Death Notes starting on line 4026:

            if (_DeathNotes != null)
                if ((victimType == 5 && (killerType == 26 || killerType == 5 || killerType == 6 || killerType == 7 || killerType == 8 || killerType == 9 || killerType == 10 || killerType == 11 || killerType == 12 || killerType == 14 || killerType == 15)))
                {
                    for (int i = 0; i < _channelCount; i++)
                    {
                        if (_settings.Channels[i].perms.Contains("plugin_deathnotes_pvp"))
                        {
                            GetChannel(Client, _settings.Channels[i].Channelid, chan =>
                            {
                                chan.CreateMessage(Client, Translate("PLUGIN_DeathNotes_Death", dict));
                            });
                        }
                    }

                }
//                else if ((victimType == 2 && killerType == 5) || (victimType == 5 && killerType == 2))
                else if (((victimType == 2 || victimType == 25 || victimType ==27) && killerType == 5) || (victimType == 5 && (killerType == 2 || killerType ==25 || killerType ==27)))
                {
                    for (int i = 0; i < _channelCount; i++)
                    {
                        if (_settings.Channels[i].perms.Contains("plugin_deathnotes_animal"))
                        {
                            GetChannel(Client, _settings.Channels[i].Channelid, chan =>
                            {
                                chan.CreateMessage(Client, Translate("PLUGIN_DeathNotes_Death", dict));
                            });
                        }
                    }

                }

Rustcord indeed needs to be updated to reflect the DeathNotes changes. Please post this note in the Rustcord help. Thanks!

Merged post

UPDATE: So, I use and love Rustcord myself, and made similar changes to the above a few months ago. I tried to reach out to the Rustcord dev about this and received no response. In any case, I looked at the above posted code more closely and compared it to mine and noticed a few small issues. The above is great work, but there are a few omissions in the NPC section. I highly recommend using the below, and I added some comments to assist the reader in understanding which enum value points to what entity type.

if (_DeathNotes != null)
{
    //5 is player, 6 is trap, 7 is turret, 8 is barricade, 9 is externalwall, 10 is heatsource, 11 is fire,
    //12 is lock, 14 is other, 15 is none, 26 is SAM site
    if ((victimType == 5 && (killerType == 5 || killerType == 6 || killerType == 7 || killerType == 8 ||
                             killerType == 9 || killerType == 10 || killerType == 11 || killerType == 12 ||
                             killerType == 14 || killerType == 15 || killerType == 26)))
    {
        for (int i = 0; i < _channelCount; i++)
        {
            if (_settings.Channels[i].perms.Contains("plugin_deathnotes_pvp"))
            {
                GetChannel(Client, _settings.Channels[i].Channelid,
                    chan => { chan.CreateMessage(Client, Translate("PLUGIN_DeathNotes_Death", dict)); });
            }
        }

    }
