v0.13.0

Breaking Changes

• append the output suffix directly WITHOUT an automatic @ separator (-s 2x now yields file2x.jpeg) and update the CLI help accordingly
• accept a UTF-8 file.list as an input file list, with one file path per line (blank lines are skipped, surrounding whitespace is ignored, and relative paths are resolved against the current working directory); when a file.list is provided, all other input file arguments are ignored

Features

• expand glob patterns in input paths on all platforms (previously Windows-only), preferring existing literal paths
• add 100l and 100s resize values that anchor on the longest or shortest side of each image
• add --reduce-only and --enlarge-only as aliases for --no-upscale and --no-downscale

Bug Fixes

• reject malformed width and height --resize values such as 1.5w or abc100w instead of silently extracting the first run of digits
• map each chained --resize value from the size the previous resize left behind, so a chain composes instead of every value mapping the original dimensions
• fix a deadlock with a single-threaded pool by acquiring the concurrency permit inside the worker, and return an error instead of panicking when the thread pool cannot be created
• write outputs atomically through unique temporary files and publish them by rename, with a recoverable swap when replacing existing files on Windows
• detect collisions before any processing: duplicate output mappings, outputs overwriting another input, metadata path conflicts, and output paths identical to --backup paths (path names are treated as case-insensitive on every platform as a fail-safe default, covering case-insensitive Linux mounts, and aliases are resolved through canonicalization for existing paths)
• never overwrite or delete an existing --backup file; create backups via hard link with a no-clobber copy fallback and remove the original input only after a successful publish
• normalize input paths without canonicalization so symlinked directory layouts are preserved, and reject output parents that resolve outside the output root
• return non-zero exit codes when no inputs are found, an encoder fails, a collision is detected, files fail, or metadata cannot be written
• fix WebP animation encoding by warning and encoding only the first frame; compute per-frame durations from timestamps in the decoder
• guard against empty frame lists in the AVIF, MozJPEG, OxiPNG and WebP encoders instead of panicking
• restrict MozJPEG to 8-bit output and fix OxiPNG 16-bit endianness for non-RGB colorspaces
• apply ICC profiles to 16-bit frames without panicking and preserve frame timing metadata
• prevent integer overflow panics in quantization and resize, and surface resize worker panics as errors

Improvements

• validate suffixes and output file names (including Windows reserved names) up front, reject recursive inputs without a common root and duplicate output mappings with clear errors
• write JSON metadata atomically and use saturating arithmetic for size and space-saved statistics
• add end-to-end regression tests covering single-thread processing, recursive output layouts, backup collisions, existing-backup protection and non-zero exit codes
• regenerate the AVIF test fixture
• update install steps of dependencies for building on Windows

Dependencies

• bump zune-imageprocs to 0.5.1 (stable) and regex to 1.13
• bump jxl-grid to 0.6.2, jxl-oxide to 0.12.6, log to 0.4.33, indicatif to 0.18.6, anyhow to 1.0.103 and serde_json to 1.0.150
• replace winres with winresource 0.1.31 and make glob a general dependency
• pin ravif 0.13.0 without default features for aarch64-unknown-linux-musl

Build / CI

• rewrite the CI workflow: build and test on main and dev, Ubuntu 24.04 / Windows 2025 / macOS 15 runners, cross builds for aarch64-unknown-linux-musl with a pinned image, qemu runner for aarch64 Linux, actions/checkout@v7, concurrency grouping and read-only permissions
• use yasm for the libaom build, fix artifact download errors and silence Homebrew tap warnings on macOS
• remove the config.toml pre-release override and set the Windows pre-release version in build.rs
