v2.3.0

WebP4j Release

What's Changed

• Zero-copy pixel pipeline — Reworked the JNI bridge so BufferedImage rasters cross into libwebp without an intermediate format-conversion buffer, and decoding writes straight into the returned image's backing array. Deterministic allocation reductions vs 2.2.0: lossy encode −98%, lossless encode −81%, decode −50% / −43% (alpha / opaque), animated encode/decode −98% / −50%.
• Zero-copy BGR encode path — Added a fast path for TYPE_3BYTE_BGR images that feeds pixels to libwebp without conversion.
• Single-pass GIF decoding — GIFs are decoded in one pass with lazy canvas allocation, making first-frame extraction ~60% faster.

v2.2.0

WebP4j Release

What's Changed

• JPMS module support — Added module-info.java via Multi-Release JAR (dev.matrixlab.webp4j.core), enabling scoped --enable-native-access on Java 22+ instead of ALL-UNNAMED (#7).

WebP4j Release

What's Changed

• Platform availability check - Added isAvailable() method to check if the current platform is supported before encoding/decoding.
• GIF to WebP conversion - Native giflib decoder with Java ImageIO fallback for maximum compatibility.

v1.3.2

WebP4j Release

What's Changed

• Build targets Java 8 bytecode by setting <maven.compiler.release>8</maven.compiler.release>.
• Critical fix: GitHub Actions macos-13 runner deprecation caused the macOS x64 (Intel) native library (libwebp4j-mac-x64.dylib) to be missing from the published JAR.
  The CI has been updated to use macos-15-intel and platform: mac-x64, ensuring the dylib is built and bundled correctly.
