Native 64-bit VST plug-in for Mac OS X (64-bit VST support requires Mac OS X 10.6 or greater; 64-bit Audio Unit requires Mac OS X 10.5 or greater; all other formats require Mac OS X 10.4 or greater.)
Bitcrusher effect added to distortion module.
Massively improved speed and responsiveness of all UI controls.
Improved CPU usage when wiring effects in the modular view.
Improved CPU usage when tweaking parameters from a hardware controller.
Improved CPU usage when rapidly switching patterns.
Sequence syncing is now more reliable for hosts which provide only periodic PPQ positional information.
Rotary controls for Looper mode and Filter types are now replaced by combo controls.
For the Windows VST plug-in, when using a relative path for the presets folder, the path is now relative to the DLL, not the host.
Standalone versions now support multiple simultaneous hardware controllers.
MIDI Program Changes are now multi-threaded, and so will no longer potentially stall the audio synthesis.
Fix for GUI freeze that could occur in certain Mac OS X VST hosts.
Preset searches are now multi-threaded. Preset browser can now immediately respond to user interaction, even whilst searching a massive preset library, or when browsing a folder containing a large number of presets..
Added soft notching for volume and crossfade controls, making unity volume and 50% crossfade mix easier to dial in.
Fixed extremely rare crash that could occur on a minority of Windows 32-bit systems when opening the UI.
Preset meta data (ie, author name, notes, tags) is now correctly displayed after loading an .FXP based preset or restoring a saved project.
Standalone application tempo can now be set to within two decimal places of accuracy.

* Native 64-bit support for Linux VST plug-ins and Standalone application formats.
* Integrated undo and redo, with unlimited history size.
* Master Sequencer, to arrange effects along a time-line.
* Random pattern generation functions.
* Partial preset support for Routing configurations.
* Thru switch for Delay Module, which if enabled allows the dry signal to be passed through when the delay effect is turned off.
* Effects are now colour-coded for easy identification.
* Category support in preset browser.
* Windows VST 32-bit plug-ins and standalone applications no longer depend on additional runtime libraries. However, these libraries are still required - and installed - for the RTAS format plug-ins.
* libjack is now weak-linked for standalone Linux. This means JACK is not required (but still recommended) for Linux users.
* Windows RTAS plug-in is now installed to the correct location on 64-bit Windows operating systems.
* MIDI Program Changes are now multi-threaded, and so will no longer potentially stall the audio synthesis.
* Fix for rare issue that stopped presets from loading in Linux Renoise when LADSPA plug-in support is enabled.
* Fixed crash that could occur when connecting Effects in the Routing Window whilst simultaneously changing Presets via MIDI.
* Fix for crash (on both Windows and Linux) that could occur when 'space' is pressed when confirming the overwrite preset dialog.
* Presets without Patterns are now considerably smaller when saved to disc.
* Improved rendering speed of Router graphics.
* Reduced CPU usage when switching or editing patterns.
* Preset Browser is now maximized to fill the entire plug-in window.
* For Windows VST (32-bit and 64-bit), the preferences file can be placed alongside the DLL file to facilitate USB or portable installs.
* Additional presets.
* Various host compatibility fixes.
* PDF manual is now printer-friendly.

* Native 64-bit versions for Windows (VST) and Mac OS X (Audio Unit).
* Integrated Preset Browser, with meta-data, tags, searching, and hot-swap support.
* Component Level Preset Support: create partial presets for each Effect.
* Effects in the Modular routing window now can be toggled on and off by double-clicking them.
* Unused Effects can be removed from the Routing window.
* Cables in the Routing window can be removed by right-clicking on them.
* A cable can now be created by dragging from an Effect's Input to another Effect's Output.
* Fixed: Gate Depth or Slew Time would jump to 0% when linking the Gate Depth or Gate Slew Time sequencer.
* Fixed: Editing the Delay Time Sequencer would sometimes cause the current Delay Time to change.
* Fixed: The same connection could be made multiple times from an Effect to an Output.
* Fixed: Rare crash could occur when loading several presets in quick succession.
* Fixed: Synced Delay time in the Sequencer window is now displayed correctly.
* Various host compatibility fixes.
