Available on the Mac App Store.

New and Improved Features for Mac OS X Lion ================

1. Lion Full Screen mode support.
2. Lion Autosaving, File Versioning, Version Browser
3. Lion Autosaving preferences: Autosaving delay & Autosaving Enable/Disable (Enabled is the default).

New and Improved Features  ================

1. New Big Feature: Flame Variants window allowing you to see how random changes affects your fractal.
Variants affect one or more of: colors, Transform weights, pre/post matrix tweaking, and mix-in other transforms.
You select the types of changes to be applied. Fractal Architect will create the variants for you.

Keep rolling the dice and play with Variations of Variations …

2. Improved Color Gradient Editor. It features a detachable fractal Preview pane. Its detached location is sticky.
You can stash good gradients in the Gradient Stash and switch between them with ease.
3. Editor windows have been resized to fit on better on 11 inch MacBook Air.

Bug Fixes =========

1. Fixed fatal crash that occasionally happened at the very end of rendering to an image file.
2. Fixed fatal crash when an thumbnail is dragged from OR dropped on the Welcome Screen -> Make New thumbnails.
3. Fixed fatal crash when a fractal preview window is closed, while the render for its fractal image has not yet finished.
4. Fixed QuickLook showing the wrong fractal during the opening animation.

Flam4 CUDA accelerated renderer and Snow Leopard =========

The Flam4 renderer is an optional feature.

1. CUDA is supported only on Macs with Nvidia GPU’s. The Flam4 rendering preference is not available on other Macs.
2. Customers must download and install a Nvidia development CUDA driver. See: http://developer.nvidia.com/cuda-downloads.
Customers can ignore the CUDA Toolkit and CUDA SDK download options.

3. CUDA  driver versions 3.2.17 and 4.0.21 are supported for CUDA GPU acceleration. (Mac Snow Leopard)

Macbook Pros (2008) with both 9400M and 9600M GPU’s should use CUDA 3.2.17 (see below for limitations with 4.0).

4. Flam4 renderer has a 35MB free GPU memory requirement. If you get a warning of low GPU memory, you may recover GPU memory by:
a) Closing other applications that consume GPU memory. (Safari in particular. Games and other graphic editors.)
b)  If that is not enough, Log out/ log back into your Mac. Restarting the Mac is another option.

5. The amount of free GPU memory (at the time of last fractal render) is shown at top right corner of Fractal Architect Log window.

Flam4 CUDA accelerated renderer and Lion =========

The Flam4 renderer is an optional feature.

1. CUDA is supported only on Macs with Nvidia GPU’s. The Flam4 rendering preference is not available on other Macs.
2. Customers must download and install a Nvidia development CUDA driver. See: http://developer.nvidia.com/cuda-downloads.
Customers can ignore the CUDA Toolkit and CUDA SDK download options.

3. Only CUDA  driver version 4 is supported for CUDA GPU acceleration with Lion. Customers must install Nvidia CUDA driver 4.0.21 or later.

4.  Macbook Pros (2008) with both 9400M and 9600M GPU’s must use lower graphics setting when rendering with the Flam4 CUDA accelerated renderer and CUDA 4.0.

Energy Saver System Preference for Graphics must be set to Graphics: Better battery life. The higher performance mode makes the Flam4 renderer unstable and unusable.

The flam3 CPU based renderer can be used with either lower or higher graphics performance setting.

5. Flam4 has a 35MB free GPU memory requirement. If you get a warning of low GPU memory, you may recover GPU memory by:
a) Closing other applications that consume GPU memory. (Safari in particular. Games and other graphic editors.)
b)  If that is not enough, Log out/ log back into your Mac. Restarting the Mac is another option.

6. The amount of free GPU memory (at the time of last fractal render) is shown at top right corner of Fractal Architect Log window.

7. Be aware that the Automatic reopening of applications after Lion reboots can leave your Mac with insufficient free GPU memory to use the Flam4 renderer.
