Changelog

The repository changelog is the canonical user-facing release history.

Notable user-facing changes are recorded here. The project follows Semantic Versioning while it is in 0.x: minor releases may change public contracts, and patch releases remain backward compatible within the current minor line.

Unreleased

Added

• removeCompressionOutput(uri) for idempotent deletion of package-owned generated cache outputs, with native ownership validation that rejects arbitrary files, traversal, symlinks, and directories.
• An iOS SDK privacy manifest declaring no tracking or collected data and the C617.1 reason used to inspect package-owned cache output metadata.
• A reproducible kit-only 12 MP JPEG evidence harness with exact environment, byte, geometry, explicit color-range visual agreement, latency, portable offline replay, and output-cleanup verification.

Changed

• The reproducible Android Docker toolchain now includes a checksum-pinned GitHub CLI and compiles the instrumentation APK so the full non-emulator repository verification lane can run in the container.

Fixed

• iOS metadata: 'strip' now removes encoder-generated JPEG APP1, APP13, and COM segments after ImageIO encoding. The marker parser rejects malformed, truncated, or trailing JPEG output through the existing ERR_ENCODE_FAILED path while leaving safe and preserve encoding unchanged.
• iOS no longer vertically inverts pixels after ImageIO has normalized an orientation-bearing input. The default pipeline now verifies EXIF orientations 1–8 through decode, transform, and encode, and native demo capture fails when the upright output does not beat a vertical-flip control.

0.4.0 - 2026-07-20

Added

• Optional AbortSignal/CompressionControl cancellation with stable ERR_CANCELLED normalization across preflight, queued, and running work.
• Decode-time downsampling for resize requests and pre-decode source/working pixel limits with stable ERR_RESOURCE_LIMIT failures.
• Additive capability fields for bounded concurrency, downsampling, and named resource limits.
• Large-image, cancellation-race, output-cleanup, and alpha decode-back native coverage.
• Version-specific v0.4.0 GitHub Release notes.

Changed

• iOS file, decode, transform, encode, and output work runs on a bounded background NSOperationQueue and uses ImageIO/CoreGraphics instead of main-thread UIKit rendering.
• Android compression runs on a two-worker bounded executor instead of the React Native module queue.
• Android and iOS publish only fully encoded cache files and remove temporary or published output when cancellation wins before settlement.
• JPEG transparency is flattened onto white consistently; PNG/WebP alpha capability now matches decode-back validation.
• Release metadata separates the intended release target from the registry-observed published npm latest, and Trusted Release selects notes from its exact validated version instead of a prior-version hardcode.

Compatibility

• Existing compressImage(options) calls and result fields remain unchanged.
• Small-image resize, crop, metadata, format, and maxBytes semantics remain compatible; the new control and capability fields are additive.
• HEIC/HEIF/AVIF output, batch APIs, progress events, animation preservation, remote URLs, and data URIs remain outside scope.

0.3.0 - 2026-07-18

Added

• Public integration and platform-support documentation.
• A GitHub Pages site with a traceable native before/after evidence contract.
• Community contribution, support, and security-reporting paths.
• Compatibility and trusted-release gates.
• The ImageCompressionKitErrorCode public TypeScript export.

Changed

• The podspec source tag now follows the repository's v<version> tag format.
• Package and repository links use the canonical public documentation site.

Compatibility

• Native compression and output behavior remain unchanged from 0.2.62.
• Android requires API 23 or newer; iOS requires 13.4 or newer.
• Expo requires a development build or prebuild. Expo Go is unsupported.
• The verified release lanes cover React Native 0.73.11 Legacy, React Native 0.86.0 Legacy/New, and Expo 57.0.7 development builds on Android and iOS.
• Intermediate React Native versions accepted by the >=0.73 <1.0 peer range are not individually release tested.

0.2.62 - 2026-07-17

• Split npm-user documentation from repository release-evidence operations.
• Added semantic documentation and current-status gates.
• Preserved release evidence, native behavior, and public API compatibility.

Complete 0.2.x implementation and evidence history is preserved in the repository history and GitHub Releases.
