CHANGES IN tinyimg VERSION 0.4

• Added tinyjpg() for JPEG optimization (using the mozjpeg Rust crate).

• Added tinyimg() as a general entry point for optimizing both PNG and JPEG files in a directory or a vector of paths.

• Added tiny_output() helper to generate safe output paths with lossy/quality suffixes (e.g., foo_l2.3.png, foo_q70.jpg), now the default output for all three optimizers.

CHANGES IN tinyimg VERSION 0.3

• Added optional lossy PNG optimization before lossless oxipng optimization.

• Changed the primary API from optim_png() to tinypng().

• Updated benchmark examples for lossy optimization results, visual comparisons, and lossy-level plots.

CHANGES IN tinyimg VERSION 0.2

Initial CRAN release

This is the first CRAN release of tinyimg. The package provides tools for optimizing and compressing images using Rust libraries.

• PNG optimization via the oxipng Rust crate

• Support for single file and directory optimization

• Configurable optimization levels (0-6)

• Optional alpha channel optimization for transparent pixels

• Preservation of file permissions and timestamps

• Verbose output showing file size reduction

• Recursive directory processing
