New in Mixxx 2.3.0 (Jun 29, 2021)

Hotcues:
Add hotcue colors and custom labels by right clicking hotcue buttons or right clicking hotcues on overview waveforms #2016 #2520 #2238 #2560 #2557 #2362
Mouse hover cues on overview waveform to show time remaining until the cue #2238
Hotcue & Track Colors:

Add customizable color palettes for hotcue and track colors #2530 #2589
Add hotcue color find-and-replace tool #2547
Importing From Other DJ Software:
Import cue points, track colors, and playlists from Serato file tags & database #2480 #2526 #2499 #2495 #2673 #3885
Note: Mixxx does not yet support multiple loops per track. We are working on this for Mixxx 2.4. In Mixxx 2.3, if you import a track with multiple loops from Serato, Mixxx will use the first loop cue as the single loop Mixxx currently supports. The imported loops are still stored in Mixxx’s database and are treated as hotcues in Mixxx 2.3. If you do not delete these hotcues, they will be usable as loops in Mixxx 2.4. Serato keeps loops and hotcues in separate lists, but Mixxx does not, so loops from Serato are imported starting as hotcue 9.
Import cue points, track colors, and playlists from Rekordbox USB drives #2119 #2555 #2543 #2779
Note: The first Rekordbox memory cue is imported for the main cue button in Mixxx and the remaining Rekordbox memory cues are imported as Mixxx hotcues, starting with the next hotcue number after the last hotcue from Rekordbox.
Note: Mixxx does not yet support multiple loops per track. Imported loops from Rekordbox are treated like imported loops from Serato, so refer to the note above for details.
Intro & Outro Cues:
Add intro & outro range cues with automatic silence detection #1242
Show duration of intro & outro ranges on overview waveform #2089
Use intro & outro cues in AutoDJ transitions #2103
Deck cloning:
Add deck cloning (also known as “instant doubles” in other DJ software) by dragging and dropping between decks #1892 and samplers #3200
Clone decks by double pressing the load button on a controller (with option to disable this) #2024 #2042

Music Feature Analysis:
Multithreaded analysis for much faster batch analysis on multicore CPUs #1624 #2142 lp:1641153
Fix bugs affecting key detection accuracy #2137 #2152 #2112 #2136
Note: Users who have not manually corrected keys are advised to clear all keys in their library by pressing Ctrl + A in the library, right clicking, going to Reset -> Key, then reanalyzing their library. This will freeze the GUI while Mixxx clears the keys; this is a known problem that we will not be able to fix for 2.3. Wait until it is finished and you will be able to reanalyze tracks for better key detection results.

See the sound of your music. With RGB waveforms, bright red means killer bass, blue glints where you find crisp hihats, and soft greens show you when the lyrics come in. A quick glance at the waveform overview and you'll know if a track is banging or just right for sunrise.
Four Microphones, Four AUX Inputs, Microphone Ducking:
Radio DJs, MCs, and users with external gear will appreciate the flexibility of 12 total external audio inputs. And with auto-ducking, listeners will always be able to hear you over the music.

Preview Deck:
A highly-requested feature, the new preview deck allows you to preview tracks in your headphones without having to load them into a main deck. Just click preview on any track in the library and it will start to play in your headphones.

New in Mixxx 1.9.0 Beta 1 (Dec 6, 2010)

Shoutcast / Icecast support:
Mixxx can now broadcast over the internet (heavily requested feature)
External Mixer Support:
The new Sound Hardware preferences pane allows you to route each playback deck separately, which allows you to use Mixxx with an external mixer.
ReplayGain normalization:
A user from our forum worked closely with our developers to fully implement volume normalization, including performing the ReplayGain analysis for tracks which are not tagged.
Waveform Gain:
The scrolling waveforms now scale according to the channel gain for better visual feedback.
Key lock buttons:
Formerly known as "pitch-independent time stretch", there are now easily accessible key-lock buttons for each for deck.
Revamped default skin:
Since the original source material for the Outline Netbook skin was lost eons ago, our artist completely redid it from scratch and tweaked it for better visibility. The new skin has also added EQ kill switches.
HSS1394 support (Windows, OS X):
Mixxx now supports firewire HSS1394 MIDI devices such as the Stanton SCS 1 series.
Improved FLAC support:
We're now using libFLAC directly for smoother FLAC decoding.
Revamped metadata parsing:
Integration of TagLib allows Mixxx to parse more metadata from songs, and do it more consistently.
Metadata writing:
Mixxx can now write changes in song metadata back to disk. This feature is off by default, and can be enabled in the Library preferences pane.
Millisecond time display:
The time counters in Mixxx now have an extra millisecond display.
Library improvements:
Played column - The library now indicates whether a song has been played in the current session already, and also counts the total number of times the song has been played.
Ratings column - 5 stars, no stars, or anywhere in between.
Better search - Search now searches in more columns, and by-term instead of by-phrase.
Revamped iTunes integration - A rewrite yielded a significant speedup of iTunes parsing.
Faster library scanning - The library scanner should perform much better on large libraries.

Hotcues:
Since everyone's been waiting ever so patiently for this release, we decided to slip a bonus in for you. Mixxx 1.8.0 Beta 2 adds hotcues, which are cue points that start playing when triggered. These are handy for impromptu drumming and remixing because you can trigger different parts of a song quickly. Although our default "Outline Netbook" skin doesn't yet show the hotcue positions on the main scrolling waveform display, the hotcues do show up in the smaller waveform summary.
The keyboard shortcuts for hotcues are Z, X, C, and V on Player 1, and M, , and ? on Player 2. Now go chop some beats!
Audio Playback Plugins:
The new audio playback plugin framework lets you to install third-party plugins that give Mixxx the ability to playback extra audio formats. Sometimes support for an obscure audio format is difficult to maintain or may be legally encumbered in certain jurisdictions, either of which would preventing us from supporting it. However, third-party developers can now add support for extra audio formats to Mixxx at their own discretion.
Fullscreen key changed to F11 to conform to de-facto standard.
