试用了一下，有不少有用的新特性，包括改进的油画刀、支持按住空格键移动画布（不过仍不支持像PS那样用Ctrl+（Alt+）Space缩放画布）、按住H、V键临时反转画布查看等等。似乎原来一个困扰我已久的BUG（用铅笔工具和粉笔工具，收笔时经常会花上100%力度的一个点）也已经修复了。
感谢楼主的发布！
完整的新特性如下：
Tweaks & Features.
* Palette Knife: We reworked the Palette Knife to improve smearing and blending quality.
* Dry Brushing: Added a 'Dry Brush' function. When you take the Oil Brush or Paint Roller Loading to 0% the tool applies no paint, you can use it to blend existing paint as if it was clean.
* Quick Mirror Check: Added a 'Quick Mirror' function that allows you to do a quick 'mirror check' of your painting. Holding down the H key flips your painting horizontally, holding down the V key flips it vertically. When you release the key, the painting returns to its normal orientation. This function is for people who like to be able to do mirror checks of their work to check for structural problems.
* Background Colour: You can now change the background colour used by ArtRage. If your canvas is smaller than the ArtRage window, select the colour you want and Alt/Option-Click the background. The default colour is white.
* Painting Name: Added the name of your current painting to the titlebar of the ArtRage window.
* Spacebar Move & Rotate: The Spacebar can now be used to move the canvas. Hold the spacebar down and left click/drag to move the canvas. When you release the spacebar, your selected tool will work again. To rotate the canvas, hold down the spacebar then the Alt/Option key and left click/drag the canvas.
* Multi-User Support: Changed how ArtRage stores its registration and user preference information so that multiple user accounts on one machine will have easier access to the application.
* Larger Tool Sizes: Added the ability to 'oversize' tools. When you single click the tool size preview you are prompted to enter a percentage value for the tool size. You can now manually enter sizes up to 500%. You can stil only use the standard size preview slide functionality to reach 100%, but some users had requested larger tools. Please note, you may experience some unusual behaviour in tools over 100%, we do not suggest using this feature unless you are working on extremely large documents.
