lemonade-sdk/lemonade candidate-v2026.39.1

v2026.39.1 (release candidate)

on GitHub

Headline

• The /images/edit endpoint added for image editing, backed by thenoise 0.7.1 and expanded AMD ROCm GPU support.
• allowed_origins now accepts :* wildcard ports and *.domain subdomain patterns for local development and homelab setups.
• New /v1/docs endpoint serves browsable API reference documentation with a JSON index and individual markdown pages.
• Configurable VRAM auto-eviction via auto_evict and auto_evict_threshold_pct, with prompt cache now preserved during soft-idle transitions.
• Prerelease candidate builds available for early testing via GitHub prereleases under candidate-v<version> tags and the Docker candidate image tag.

Breaking Changes

• Model version format changed from X.Y.Z to YYYY.WW.N or YYYY.WW.0~<count>.<hash>; tools and scripts that parse --version output or compare version strings must be updated.
• The /models and /pull/variants endpoints now serialize registry_source as an empty string for models without an explicit source override, instead of 'huggingface'; clients that assume the field is always set to a registry name will need to handle empty values.
• The unversioned /docs endpoint subtree now returns a JSON 404 instead of falling through to the SPA web app; any client relying on that fallback will receive a 404 response.
