Previous Versions
ArchiveFor most people the Stable Release above is the right download. These are kept for anyone who needs to match an older profile, plugin, or workflow. Tap a version to see what changed.
OrcaSlicer v2.4.1 ▸
Maintenance release on top of 2.4.0. Introduced the first native Windows ARM64 build (Snapdragon X Elite and similar devices), a “Minimal” chamber-temperature field for filaments, and a rework of skirt/brim generation that fixed a regression affecting per-object and sequential printing.
View all v2.4.1 downloads & full changelog on GitHub →OrcaSlicer v2.4.0 ▸
Added a Microsoft Store install channel for Windows, the option to send sliced jobs to a printer as a packaged 3MF, faster slice-to-preview processing via G-code pattern caching, and a further skirt-generation overhaul — plus Orca Cloud offline-login support and a broad round of bug fixes.
View all v2.4.0 downloads & full changelog on GitHub →OrcaSlicer v2.3.2 ▸
Patched a path-traversal security issue in 3MF import, added a configurable wipe-tower type setting, brought a round of Linux/Flatpak stability improvements, and fixed a CLI segfault. The official Flathub package (flatpak install flathub com.orcaslicer.OrcaSlicer) also launched around this release.
OrcaSlicer v2.3.0 ▸
An older release kept here for anyone who needs to match a workflow or profile built on this specific version. Three stable releases and a security fix have shipped since, so most people should use the current Stable Release above instead.
View all v2.3.0 downloads on GitHub →Beta & Alpha Pre-releases ▸

This covers every beta/rc/alpha tag, including v2.3.2-beta2 (Feb 15, 2026), v2.3.2-rc (Mar 1, 2026), v2.3.2-rc2 (Mar 6, 2026), v2.4.0-alpha (May 25, 2026), and v2.4.0-beta (Jun 9, 2026).
