Development Roadmap

This page represents the opinion of the Mixxx development team, as such it is not editable by general users. If you have comments or suggestions, please contact us.

Main Design Principles

These are some core goals which are critical for Mixxx to become a world-class application, somewhat in order of importance:

Stability - Having a stable platform for DJs to work from is key
Performance - Optimize latency over throughput
Support a good level of latency for as many configurations as possible
Usability - Most functions must be bonehead-easy to use. The manual must not be required reading!
Good hardware support
For as many devices as possible
With easiest possible setup
Support all likely input formats
Features
Should be guided by feedback from DJs
Great care should be taken to ensure that stability is not compromised by new features
Mixxx doesn't need to make the coffee, features should demonstrably improve the user experience

1.8.0

// Release Schedule //

Nov 16 2009 -- Feature Freeze
Feb 5 2010 -- private(-ish) beta testing
Feb 15 2010 -- Mixxx 1.8.0 Beta 1
May-July -- Mixxx 1.8.0 Beta 2
??? - Mixxx 1.8.0 Final

Keep in mind that as we have no full-time developers, this schedule is likely to change due to external pressures. Don't plan anything important around it.

We tried to sync up with the Ubuntu release cycle, but were unable to commit enough developer time to fixing bugs, despite our best efforts. (Feature freeze for Lucid Lynx was February 18th, 2010.) We did get Mixxx 1.8.0 into Ubuntu 10.10 though! To-do list

New main features:
