Recent Releases

v0.4.43 — current stable release

v0.4.43 (opens in a new tab) improves recovery and annotation persistence:

• Cleans up model workers after download or load errors so another model can be selected without restarting.
• Skips invalid images during SAM preload instead of terminating the worker.
• Persists grouping and ungrouping changes, marks the document dirty, and makes the operation undoable.
• Closes JSON label files deterministically so Windows can immediately overwrite or delete them.
• Uses a pinned absolute AnyLearning banner URL that renders correctly on PyPI.
• Publishes six CPU/accelerated artifacts with SHA-256 digests and native-runner launch checks.

v0.4.42 — packaging validation

v0.4.42 (opens in a new tab) replaced the affected v0.4.40 binaries and tightened release validation:

• Preserves required PyInstaller symlinks in macOS ZIP archives.
• Bundles the matching libexpat in Linux frozen applications.
• Launch-tests extracted macOS archives and frozen Linux/Windows applications before upload.
• Publishes six CPU/accelerated artifacts for Linux, Windows, and Apple Silicon macOS.

Avoid the v0.4.40 macOS and Linux artifacts. The v0.4.41 publication was cancelled during validation; use v0.4.42 or newer.

v0.4.39 — cross-platform accelerators

v0.4.39 (opens in a new tab) introduced deterministic ONNX Runtime provider selection:

• NVIDIA CUDA on Linux and Windows, including packaged pip CUDA/cuDNN runtime libraries.
• CoreML on Apple Silicon.
• DirectML, OpenVINO, TensorRT, ROCm, MIGraphX, WebGPU, and vendor NPU provider aliases.
• Explicit selection with ANYLABELING_DEVICE and CPU fallback when a requested provider is unavailable.
• Intel OpenVINO NPU and Qualcomm QNN/HTP provider options.

See Hardware Acceleration for installation and device selection. No binary artifacts were published for v0.4.39; use v0.4.43 or newer for installers containing this work.

v0.4.37–v0.4.38 — stability and model fixes

These releases fixed several user-visible failures:

• The Ctrl+O file dialog crash caused by unscoped PyQt6 enums.
• Crashes from stale canvas selections and shape movement at image boundaries.
• Empty configuration files now fall back to defaults.
• Invalid SVG files are no longer advertised as supported images.
• Brightness and contrast editing supports 16-bit TIFF images.
• Escape and drawing-mode transitions no longer hide or corrupt the labeling workspace.
• SAM 3 tokenizer data is included in frozen applications.

For every published artifact, prefer the latest release (opens in a new tab) unless a project requires a pinned version.
