While making an improvement to the file tree, I unfortunately introduced a bug in the Workzone visibility checkboxes of b7c and did not catch it before release: clicking the checkbox of an unselected file had no effect.
I sincerely apologize for the inconvenience this may have caused. The issue is fixed in b7d, please update. (Workaround in b7c: click the file name first, then its checkbox.)

The brush paints everywhere again. On surfaces seen at an angle, the brush could stop painting after the first stroke, forcing you to rotate the part to face it. This is fixed, whatever the viewing angle.
Painting and saving are much faster. Saving a painted model now takes about fifteen seconds instead of over a minute, the brush responds four times faster on large models, and undo is instant. Your files no longer grow needlessly with every save.

A bug introduced in b7 could stop Extract from working. On some valid selections, Interlocking and Patch were refused with the message "This selection has concentric border curves (a ring shape)". Those selections were not rings: the check was wrong, and it is fixed in b7a.
If you are on b7 and Extract refused a selection, download b7a.

Windows
Download the installer and run it. Follow the on-screen instructions.

macOS (Apple Silicon M1 to M4)
Download Split3r 1.4.0 b0 for macOS
Please read this carefully before downloading.
This is the very first macOS release of Split3r. It has been tested on Macs ranging from M1 Pro to M4.
The app is signed with our official Apple Developer ID (Team ID: 7678SMCXDA), so you can verify its authenticity.
However, this build is not notarized yet. macOS will therefore block it by default, and you will need to use the Terminal to adjust security settings and allow the app to launch.
If you don't know what the Terminal is, or what a "notarized" app means, we recommend that you do NOT purchase Split3r right now. A fully notarized version is coming soon, when it is available, you will simply double-click to install, with no Terminal commands required. We will announce it on this page as soon as it ships.
If you are comfortable with the Terminal and want to use Split3r today, you must follow the installation guide step by step.
Skipping any step will prevent Split3r from starting or cause it to crash.

Linux (x64)
Split3r for Linux is provided as an AppImage, a single self-contained file, no installation required.
https://www.split3r.com/download/linux/split3r-1.4.0_b0-x86_64.appimage
To run it:
Note: some Linux distributions require FUSE to run AppImages. If the file refuses to launch, install the libfuse2 package (on Debian/Ubuntu: sudo apt install libfuse2).
Cohabitation with Split3r 1.3.1
Split3r 1.4.0 is designed to run side by side with your existing 1.3.1a release, so you can test the new features without disrupting your stable workflow:
Windows: the 1.4.0 beta installs alongside 1.3.1. Both versions have separate shortcuts and settings, and can be launched independently.
Linux (x64): AppImages use different filenames for each version, so you can simply keep both files in the same folder and run whichever one you need. No installation, no conflict.
macOS (Apple Silicon): 1.4.0 is the very first macOS release of Split3r, so there is no previous version to coexist with.
Keep using 1.3.1 for production work, and switch to 1.4.0 whenever you want to try the new features.
