Bug tracker

The Mojang Bug Tracker (also known as Mojira) is the official website location for players to report bugs for Minecraft. Similar to the feedback site, it is community moderated. The bug tracker is located at bugs.mojang.com.

History
Previously, the Issues page on the Minecraft Wiki was used to maintain issue reports. Many people complained that the process was too complicated. Due to the high demand for a proper bug tracker instead of using the wiki, Mojang contacted Atlassian, which became their choice due to being flexible and customizable. An email was sent to Atlassian to gain help on making a proper bug tracker. Atlassian immediately offered to help, providing a free JIRA license. A video was published to showcase their improved JIRA developer's API for JIRA v5.0.

Announcement
On October 24, 2012, the bug tracker was officially released by Erik Broes and Atlassian using their issue tracker, JIRA.
