Il try my best to explain most of the stuff.
I wouldnt really say a lot has changed the only major changes have been the merger between the devkit and normal editor in which the terrain tools were massively upgraded in the normal editor. I just grabbed these guides from the Official Unturned Discord Modding Section.
I recommend you join the Official Discord as there are a lot of people who could help you.

For the Lighting tab this essentially lets you manipulate how the environment is shaded and colored during different times of the day. Other things are changing the sea level and at what height snow starts falling. The weather multipliers I dont know about somebody else from the community can explain those.
The Roads and navigation tabs havent really changed and you could figure those out for yourself or just ask.
The nodes are just a random tab that lets you place player spawnpoints, set location names on your charts and satellite maps and the airdrop marker. (There might be more to this for people modding the game but thats a question for the curated map makers)
You essentially select one of the three nodes you want and press e on the terrain to spawn it and select it with hover select and then set your IDs or location name. (Dont know what the ID would be for on the spawnpoints exactly)
The spawns tab il leave for somebody else to explain but theres more to it like creating lists with items and then providing those in the editor but thats all outside the editor in the spawn tables tab I believe.
For the Objects Tab
Specificially knowing that pressing Ctrl B while having a object select and then Ctrl N on another will teleport the selected object to the origin of the previous one
Also while moving a object holding Ctrl will result in snapping it which can be configured with Snap Translation for more precise movement
Rotation is a bit weird at the start you dont do a circle motion to rotate the object instead you go in the direction of the white line and you can also do snap rotation and set the rotation amount with snap rotation
Other shortcuts include ctrl s to save your level, ctrl z to undo a change and your regular ctrl c and v to copy paste objects.
One important thing about objects is this setting you either have global or local.
Global means whenever you select a object it will always be facing with its selection arrows in the north east west south direction by default spawning in new objects will face in these directions
Local means your object arrows will actually look in the direction in which the object has been rotated for if you decide to make a building that is 45 degrees rotated for example.
Certain objects come with a variety of colors this can either be changed by spawning in new objects or specificially selecting the material index.
Theres also a option on certain objects like buildings to disable culling volumes these essentially stop rendering smaller objects inside the building to keep your game performance good and I wouldnt recommend disabling.
Material Palette GUID is probably about setting custom colors for the building by referencing specific GUIDs in certain files in your game folder.
The visibility tab if I remember correctly from Danaby2 can be just used to look around the map for places that might be performance intensive such as this stack of buildings in which the first line tells you the position on the map the second line tells the amount of objects present on that position (dont know about the percentage) and the last line just tells you how many vertices I believe are on that position vertices being the things out of which the objects are made off.
Players just your generic player spawnpoints with their being a alt which is also used for things such as npc quests with Kuwait making use of it.
Volumes is something for somebody else to explain but just basically volumes you can place to create things such as dark caves, water ponds, safezones, player barriers and etc.
I hope you were able to understand this rough explanation with my suboptimal English grammar and everything else. (If you even decided to read through this) And I hope me spending probably from my 3k hours of playtime in this games editor as a kid helped you in some way.
All in all I really recommend you head on over to the official Unturned Discord server.
