This is an updated alpha build for 5.2 that fixes a handful of issues and crashes.

You can read more about 5.2 and what it includes by reading the release notes for the first alpha.

Change Log

Changes since 5.2 Alpha (build 9625):

• The selection will no longer be tinted when opening an effect or adjustment.
• Improved the latency of the brush tool “preview cursor” by 1 frame.
• Added some extra digits past the decimal place for the zoom level in the status bar.
• Shortened the length of the animations used when closing an image or deleting a layer.
• Fixed Edit -> Paste into New Image not setting the color profile, resulting in it always being sRGB.
• Fixed a rare crash with the brush tools when adjusting the brush size. This crash could only be reproduced with external automation (e.g. macro record/playback with AutoHotKey).
• Fixed copy/paste sometimes adding an extra row or column of pixels around the edge of the image due to bad rounding after floating point precision drift.
• Fixed a crash when pasting images that are CMYK, or which have a LUT-based color profile, or a mismatched color profile (e.g. CMYK profile on RGB image).
• Fixed some issues with copy/paste of indexed (e.g. 8-bit palettized) images.
• Fixed not being able to use new Effect plugins compiled against the 5.2 Alpha (build 9625) binaries.
• Changed the package ZIPs so that they use forward slashes instead of backslashes, which simplifies working with these outside of Windows (e.g. for WINE porting effort).
