Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

[12.1.1] - 2025-01-02

Changed

• Updated @343dev/gifsicle and @343dev/guetzli packages, which now allow Optimizt to work on Alpine Linux without installing additional packages. Previously, the gcompat package was required as the guetzli and gifsicle binaries were built for glibc-based systems, which is absent on Alpine Linux.

[12.1.0] - 2025-12-24

Added

• Added --prefix and --suffix flags to add custom prefixes and suffixes to optimized file names.

Changed

• Updated log output to display output filenames instead of input filenames.

[12.0.0] - 2025-12-23

Added

• Configure trusted publishing for npm package to enhance security by eliminating token-based publishing risks (see npm trusted publishers).

Changed

• BREAKING: Increase minimum Node.js version to 20.19.0 due to dependency requirements.
• BREAKING: Update SVGO config in default .optimiztrc.cjs to migrate from v3 to v4 (see migration guide).
• Update all dependencies to latest versions with a 7-day cooling period and fix versions to prevent security vulnerabilities during installations.

[11.0.0] - 2025-05-04

Added

• Added new configuration parameters in .optimiztrc.cjs:
  • optimize.gif.lossy.gamma
  • optimize.gif.lossless.gamma
• Improved Platform Support: Added arm64 binary versions for guetzli and gifsicle.

Changed

• Replaced imagemin/gifsicle-bin package with 343dev/gifsicle.

• Updated gifsicle to version 1.96.

• Reduced Dependencies: Total project dependencies decreased from 218 to 41.

  The new gamma parameters were added because of changes in gifsicle 1.96. In this version:

  • The --lossy option now measures color errors using the color space selected by --gamma (defaults to sRGB).
  • A new algorithm for computing color differences has been implemented.
  • This means --lossy=N will behave differently than in previous versions and may compress less than expected.
  • For behavior similar to previous versions, use --lossy=N --gamma=1.

[10.0.0] - 2024-10-28

Changed

• Supported Node.js version updated to 18.18 or higher.
• Replaced "gif2webp" with "sharp" for GIF-to-WebP conversions.
• Fine-tuned params in .optimiztrc.cjs.

Removed

• Removed the "webpGif" section from .optimiztrc.cjs.

[9.1.1] - 2024-10-22

Changed

• Replaced imagemin/guetzli-bin with 343dev/guetzli.

[9.1.0] - 2024-10-16

Changed

• Disabled parallel optimization of JPEG files in Lossless mode.

  Guetzli uses a huge amount of RAM. In my case, when optimizing a file of about 30 MB, one process could use up to 12 GB of memory. If there are multiple files, parallel optimization with Guetzli consumes all available RAM, causing the system to use Swap, leading to slowdowns and freezes.

  For this reason I decided to disable parallel optimization of JPEG files in Lossless mode. Now, it will take more time but will have less impact on the OS performance.

[9.0.2] - 2024-10-08

Fixed

• Fixed Guetzli install.

[9.0.1] - 2024-10-08

Fixed

Changed

• Improved image processing workflow. Check the migration guide for details.
• Changed the "File already exists" message from "error" to "info," now only shown in verbose mode.

Fixed

• Fixed the progress indicator in conversion mode. It now correctly shows the total number of items.
• Fixed output to the user directory. The original folder structure is now preserved (I hope so!).

[8.0.0] - 2024-08-05

Added

• Added EXIF Orientation tag support for JPEG.

Changed

• Improved JPEG lossless optimization process.
• Changed configuration file format to CJS.

Removed
