 Room version 10 is based upon room version 9 with the following considerations.
 
-### TODO
+### Event format
 
-* Auth rules
-* Stringy power levels
+The event format is unchanged by this room version. See [below](#event-format-1)
+for details on the current event format.
+
+#### Deprecated formatting
+
+While this room version does not change the event format specifically, some
+deprecated behaviours are strictly no longer supported.
+
+##### Power levels must be integers
+
+In other room versions, such as [v9](/rooms/v9/#power-levels-accepted-as-strings),
+power levels could be represented as strings for backwards compatibility.
+
+This backwards compatibility is removed in this room version - power levels MUST NOT
+be represented as strings within this room version. Power levels which are not
+correctly structured are rejected under the authorization rules below.
