I've stumbled upon an old forum thread saying the limit for "dropped" (floating) items is 200. Obviously items de-spawn after certain conditions are met (5 minutes in survival on PC), but the threads I found were concerning extremely large automated wheat farms whereas manually farming would gain a higher harvest than the automatic farm (because of the 200 items limit).
Can I get an answer that specifies the exact maximum number of dropped items for the latest version of Minecraft for each platform? The Gamepedia article I linked to above specifies that:
On the console edition the item entity limit is 200 in loaded chunks.
I've yet to confirm whether this is outdated information or not and my searching hasn't landed me with a specific number for the PC version, either. I'd also like to know the limit for pocket and pi editions.
