No more infinite items or major exp. boosts.
If anyone is thinking about updating to 0.14.2, please note that the glitch in which you used to be able to potentially gain substantial experience boosts by quitting to the title screen and reloading the same world when you reach the next experience level [i.e 1 to 2, 2 to 3, 3 to 4, 4 to 5… …29 to 30… …44 to 45, and so on] no longer works. Also, as of 0.14.1, the item duplication glitch involving the use of an anvil no longer works in this version—two very useful glitches that I am displeased with Mojang for removing. If you already HAVE updated, I sincerely hope that you have another device [that is not a Windows 10 device] on which you have not updated Minecraft. You can copy your world* to that device to duplicate your items, then copy it back to your device* with MC 0.14.2 installed, but be warned--any world created in a later version of Minecraft cannot be opened in an older version. For example: a world created in 0.14.1 cannot be opened in 0.14.0 or earlier** [that is if you HAVE any version older than 0.14.0].
*Versions of Minecraft installed on all involved devices must match. I cannot be held responsible if you become unable to re-enter your world on either device. Please make a backup of your world before copying it to any of your other devices. Also try doing this before attempting anything dangerous in your world like entering The Nether, mining near lava, taking on a horde of monsters, etc.
**Created worlds have no forward compatibility. Any world created in an older version of Minecraft can be opened in a later version, but creating a world in a newer version of Minecraft and trying to open it in a version prior to any version in which the world was created will cause incompatibility issues. For example: if you create a world in 0.14.2 and copy it to 0.14.1 or 0.14.0 and try to open the copied world there, it will not open. As always, exercise caution when diving into your Minecraft data on all versions and BACK UP YOUR FILES.
