+## [2.1.0](https://launchpad.net/mixxx/+milestone/2.1.0) (2018-04-15)
+
+After two years of hard work, we are pleased to announce Mixxx 2.1. We
+have overhauled the effects system, redesigned the skins, added and improved
+lots of controller mappings, rewrote the audio file decoders twice, and of
+course fixed a bunch of bugs. Download it!
+
+Here is a quick summary of what is new in Mixxx 2.1.0:
+  * Graphical interface scales for high resolution screens
+  * Overhauled Deere and LateNight skins
+  * New Tango skin
+  * Effects are synchronized to the tempo
+  * Effects are processed post-fader and post-crossfader and can be previewed
+in headphones

+use of effect chains
+  * Nine new effects: Autopan, Biquad Equalizer, Biquad Full Kill Equalizer,
+Loudness Contour, Metronome, Parametric Equalizer, Phaser, Stereo Balance,
+Tremolo
+  * Loaded effects and their parameters are saved and restored when Mixxx
+restarts
+  * More transparent sounding equalizers (Biquad Equalizer and Biquad Full Kill
+Equalizer)
+  * Improved scratching sounds with jog wheels, vinyl control, and dragging
+waveforms with the mouse
+  * Simplified looping and beatjump controls
+  * Configurable rows of 8 samplers with up to 8 rows available for a total of
+64 samplers

+  * Improved volume normalization algorithm (EBU-R 128)
+  * Filter library table by crates
+  * Sort musical keys in library table by circle of fifths
+  * Write metadata tags back to audio files

+at the same time
+  * Broadcast and record microphones with direct monitoring and latency
+compensation
+  * Broadcast and record from an external mixer
+  * Booth output with independent gain knob for using sound cards with 6
+output channels without an external mixer
+  * Prevent screensaver from starting while Mixxx is running
+  * CUP (Cue And Play) cue button mode
+  * Time remaining and time elapsed now take into account the tempo fader
+  * Clicking cover art now shows it full size in a separate window
+  * and of course, lots and lots of bug fixes.
+

+
+For users upgrading from older versions of Mixxx, we have a few important
+announcements. First, if you are using Windows, you will have to uninstall any
+old versions of Mixxx before you can install 2.1. How to uninstall Mixxx
+varies on different versions of Windows:
+  * Windows Vista, 7, and 8: Start > Control Panel > Programs > Uninstall a
+Program [Guide](https://support.microsoft.com/en-us/help/2601726)
+  * Windows 10: Start > Control Panel > Programs > Programs And Features > look
+for Mixxx > Uninstall [Guide](https://support.microsoft.com/en-gb/help/4028054/windows-repair-or-remove-programs-in-windows-10)
+
+If you are upgrading from an older version of Mixxx and have MP3 files in
+your library, we have another important announcement. The good news is that we
+fixed a bug where the waveforms and audio playback of MP3 files were
+misaligned. The bad news is that we have no way of knowing which MP3 files were
+affected or how much the offset was. That means that waveforms, beatgrids,
+cues, and loops from older versions of Mixxx may be offset by an unknown amount
+for any MP3 file. Only MP3 files were affected by this bug; other audio file
+types are unaffected. You can either correct your beatgrids and cue points
+manually for each track, or you can clear this information for all MP3s and
+start fresh. Regardless, we recommend clearing the waveforms for all MP3
+files. To clear these, type "location:mp3" into the library search bar, press
+Control + A to select all tracks, right click, and select the information you
+want to clear from the menu.
+
+In the works for Mixxx 2.2, we have a big redesign of the library GUI. Along
+with that will come saving & restoring search queries plus nested crates.
+We are also planning on adding support for saving and loading custom effect
+chain presets with the ability to import and export them to share online.
+
+Want to help make Mixxx even more awesome? The biggest thing we need is more
+people. You do not need to be a programmer to help out. Giving feedback on the
+design of new features as they are being made is very valuable. Refer to the
+Testing page on the wiki for more information on how to get involved with that.
+Reporting bugs and telling us your ideas on the Launchpad bug tracker is a big
+help too! We cannot fix problems we do not know about, so please let us know if
+you find any issues with Mixxx. If you would like to help translate Mixxx into
+another language, refer to the Internationalization wiki page.  Of course, more
+programmers could always help. Read the Developer Documentation on the wiki for
+tips on getting started contributing code to Mixxx.
+
+We hope you have as much fun with Mixxx as we do!
