imgenv0.3.1

Changelog

Generated from CHANGELOG.md in the project repository. Never maintained twice.

0.3.1

24 February 2026

  • fixedWith --webp and a model that delivers WebP server-side (e.g. flux-1.1-pro), the file was saved with the original extension. The output path now always ends in .webp.

0.3.0

24 February 2026

  • changedWhen a model supports output_format, imgen requests PNG or WebP (with output_quality) directly from the API instead of re-encoding locally.
  • fixedaspect_ratio values referenced via $ref (inside allOf) are now resolved. Before, FLUX Pro images came out 1:1 regardless of the requested dimensions.

0.2.2

24 February 2026

  • fixedAn output path ending in .webp no longer overwrites and deletes the downloaded image; the download goes to a temporary .png first.
  • fixedThe downloaded image format is detected from its content instead of the file extension.

0.2.1

24 February 2026

  • fixedHTTP 429 responses are retried up to 5 times, waiting for the Retry-After header (fallback: 10 seconds).

0.2.0

23 February 2026

  • addedwebp quality in prompt files, both in defaults and per job. Priority: job, then defaults, then the --webp flag.

0.1.0

23 February 2026

  • addedCLI for generating images with any Replicate model; default black-forest-labs/flux-1.1-pro.
  • addedAutomatic schema detection for aspect_ratio handling.
  • addedSingle prompts and batch mode via JSON prompt files with shared defaults.
  • added--webp flag with optional quality (default 80).
  • addedPrebuilt release binaries for macOS and Linux (x86_64 and arm64) and a Homebrew formula.
  • changedTLS via rustls instead of OpenSSL, so the Linux arm64 build cross-compiles.
