[Unreleased]

Added

• streamQueryBatched on NativeOdbcConnection for cursor-based batched streaming (complete protocol messages per batch; preferred for large result sets).

Changed

• executeQuery (repository/service) now prefers streamQueryBatched, with fallback to streamQuery on failure.
• README and example updated to document and use streamQueryBatched.

0.1.4 - 2026-01-26

Performance

• Removed AddressSanitizer and UBsanitizer from default build configuration (70% reduction in build time: 10-15 min → 3-5 min)
• Added thin LTO and optimized codegen units for faster release builds
• Reduced binary size with strip=true

Fixed

• Corrected download URL in Native Assets hook to match GitHub release structure
• Fixed release workflow build path for Cargo workspace structure
• Fixed ffigen verbose flag syntax in workflows
• Added missing libclang-dev and llvm dependencies for cbindgen in CI

Changed

• Simplified CI/CD by removing redundant workflows (keep only release.yml)
• Added Rust dependency caching to reduce build times in CI
• Release workflow now uploads binaries to root level (no subdirectories)
• Added explicit timeout and verbose output for better debugging

0.1.3 - 2026-01-26

Fixed

• Corrected download URL in Native Assets hook to match GitHub release structure

0.1.2 - 2026-01-26

Changed

• Optimized CI/CD pipelines

0.1.1 - 2026-01-26

Fixed

• Reduced topics to 5 (pub.dev limit)
• Improved Native Assets documentation

Changed

• Removed macOS support (now Windows and Linux only)

• Prepared statements (prepare, executePrepared, closeStatement)
• Connection pooling (poolCreate, poolGetConnection, poolReleaseConnection, poolHealthCheck, poolGetState, poolClose)
• Streaming query results for efficient large result set processing
• Bulk insert operations with BulkInsertBuilder
• Database catalog queries (tables, columns, typeInfo)
