Message:

Enemies (zombies and hostile animal entities) are now shown on the map as Hostiles and require permission level 'webapi.gethostilelocation' for web viewers to see.

Animals (non-hostile entities) are now shown on the map as Animals and require permission level 'webapi.getanimalslocation' for web viewers to see.

Permission level for 'webapi.viewallclaims' is now required for a viewer to see all claims, otherwise the permission level for 'webapi.getlandclaims' will only show viewer-owned claims. A viewer requires both 'webapi.getlandclaims' and 'webapi.viewallclaims' to be set for all claims to show (you can't just set 'webapi.viewallclaims').

Permission level for 'webapi.viewallplayers' is now required for a viewer to see all players, otherwise the permission level for 'webapi.getplayerslocation' will only show the player for the currently-authenticated viewer. A viewer requires both 'webapi.getplayerslocation' and 'webapi.viewallplayers' to be set for all players to show (you can't just set 'webapi.viewallplayers').

Banned players are now hidden from the web map.

Items using 'CustomIcon' and 'CustomIconTint' are now supported (although the exact tinting may not be perfectly the same as the game).
