Technical blocks/End Portal

Java Edition
1.0.0		Beta 1.9 Prerelease 3-1			End portals have an unobtainable item form corresponding to its block ID, which has interesting model behavior. It can be obtained via inventory editors with numeric item ID 119.
					In this version, players would immediately start out with this item upon generating a world or when respawning.
					If an end portal item already existed in the hotbar, using pick block on an existing end portal block would switch the hotbar to select that block like with any other item.
					It can be placed in the Nether.
		Beta 1.9 Prerelease 3-2			The player no longer starts out with this item on world generation or when respawning.
		Beta 1.9 Prerelease 4			When attempted to be placed in the Nether or End, placement will fail but the placement sound and hand animation will still play. Replaceable blocks such as fluids, grasses and vines are deleted, and the item is also consumed in survival mode.
1.2.5		pre			End portal items can now be obtained via pick block in Creative.
1.3.1		12w16a			End portal items can now be obtained in singleplayer worlds via the /give command using the respective numeric ID.
		12w17a			End portal items can no longer be obtained via pick block in Creative.
		12w18a			Likely due to a client-server desync, end portal blocks placed with the item in the Nether/End will render the block for a frame.
1.8		14w25a			The direct item form of end portals has been removed from the game. It can no longer exist as an item in any way, only as a placed block.
Bedrock Edition
?					End portals exist as an item.
?					It is possible to obtain end portals as an item simply by replacing them with water using a bucket.
?					End portals can no longer be obtained through replacement by water.
1.9.0		?			It is possible to obtain end portals as an item by using /setblock ~ ~ ~ air 0 destroy when standing above an activated end portal block.
1.11.0		?			The above method no longer works.

Appearances

Java Edition
1.0.0		Beta 1.9 Prerelease 3			End portal items have an unstable item model which changes depending on blocks which are targeted or in loaded chunks. It uses this model in inventories, when held in first or third person view or as a dropped item.
					The end portal item initially uses a full cube model, like full cube blocks do.
					If a placed end portal block is targeted, the item model will change to a flat plane, matching the shape of the wireframe outline box that can be seen near the bottom of an end portal block when targeted.
		Beta 1.9 Prerelease 4			The end portal item now uses this texture in inventories, when held in first or third person view or as a dropped item.
		Beta 1.9 Prerelease 5			The end portal item now uses this texture in inventories, when held in first or third person view or as a dropped item.
					This is due to the grass top texture changing in this version.
1.4.2		12w34a			The end portal item now uses the aforementioned texture when in an item frame.
1.5		13w02a			The end portal item now uses this texture in inventories, when held in first or third person view, as a dropped item or when in an item frame.
					This is due to major texture storage changes in this version.
1.7.2		13w42a			End portal items now appear translucent in the inventory. As a dropped item, in a player's hand, or in an item frame, they still appear opaque.
					This is due to changes in item rendering in this version, likely to allow for stained glass to appear translucent as an item.
					NOTE: the end portal item was still animated in this version. However, the provided image appears stationary due to technical limitations.
1.8		14w05a			The end portal item now uses this texture in inventories, when held in first or third person view, as a dropped item or when in an item frame.
					This is likely due to model changes in this version, and end portal items not having an item model defined.
Bedrock Edition
?					The end portal item uses this texture.
?					The end portal item uses this texture.
