ECM v1.2.0

Bug fix release addressing Mode 2 sector reconstruction issues for PlayStation and Video CD images.

Highlights

• Mode 2 MSF Fix - Corrected sector address reconstruction for Mode 2 CD images
• Pipe Support - Fixed decoding to stdout/pipes for streaming workflows
• C23 Modernization - Adopted modern C23 features including nullptr
• Code Quality - Applied consistent formatting with clang-format

What's New

Bug Fixes

• Fixed incorrect MSF (Minute:Second:Frame) addresses when literal bytes preceded Mode 2 sectors
• Fixed ftello() returning -1 on pipes/stdout causing all Mode 2 sectors to get MSF 00:02:00
• Replaced file position queries with explicit byte counting for reliable MSF computation

Code Quality

• Adopted C23 nullptr keyword for type-safe null pointers
• Added .clang-format configuration for consistent code style
• Cleaned up redundant license headers in source files
• Documented - parameter for stdin/stdout streaming

ECM v1.1.0

A major modernization release with improved build system, testing, and robustness.

Highlights

• Modern Build System - Migrated to Meson for cross-platform builds
• Test Suite - Unit and integration tests for reliable development
• Shared Library - Common ECC/EDC code extracted to libeccedc
• Bug Fixes - Fixed integer overflow, buffer overflow, and error handling issues

What's New

Build & Packaging

• Meson build system with release/debug configurations
• just command runner for convenient builds
• Arch Linux PKGBUILD included
• C23 standard with warnings as errors

Reliability Improvements

• Large file support (>4GB) with int64_t progress tracking
• Bounds checking in type/count decoder prevents malformed file exploits
• All write operations now check for errors (disk full, I/O failures)
• Proper error code propagation throughout

Code Quality

• Shared libeccedc static library eliminates code duplication
• Comprehensive test coverage (unit + integration)
• Modern GitHub-style documentation
