Java Edition 1.7.9
This page covers a release version that has a critical issue under certain conditions.
The dedicated server for this version includes a security vulnerability in the Log4j library that could be used to perform a remote code execution exploit. It can be addressed by appending a certain JVM argument to the server startup command line.[1]

1.7.9[2] is a minor update to Java Edition released on April 14, 2014,[3] to fix some further issues with skins in 1.7.8, and to improve the speed it converts names.[3] It is compatible with 1.7.6 – 1.7.8 servers.
Changes
General
- Made Minecraft Realms button visible on title screen, but the functions of realms were not introduced yet.
Naming system
- Improved name conversion speed.
Skin system
- Added support for the new skin system.
- Loosened restrictions so NPCs and similar are still possible for now.
- Servers still have to send signed blobs to show skins, but there are no more timeout & "is it for this player" checks.
Fixes
From released versions before 1.8
- MC-4812 – Piston arm graphical glitch in the End.
From the 1.7.x release versions
- MC-51786 – 1.7.5 Minecraft Realms OP bug.
- MC-52719 – Outdated server, pretending to be 1.7.7 / 1.7.8.
- MC-52817 – "Add player" packets and "Remove player" packets are being sent out of order.
