0.2.7 - 2026-01-29

Fixed

• Native DLL cache now keyed by package version (~/.cache/odbc_fast/<version>/) to avoid loading an older DLL when upgrading the package (fixes symbol lookup error 127 for new symbols e.g. odbc_savepoint_create)

0.2.6 - 2026-01-29

Added

• README: "Support the project" section with Pix (buy developer a coffee)

Changed

• Exclude test/my_test/ from pub package via .pubignore (domain-specific tests)
• README: installation example updated to ^0.2.6

0.2.5 - 2026-01-29

Added

• Database type detection in tests: detectDatabaseType(), skipIfDatabase(), skipUnlessDatabase()
• Test helpers for conditional execution by database (SQL Server, PostgreSQL, MySQL, Oracle)
• test/helpers/README.md with usage and examples

Changed

• Dart tests run sequentially (--concurrency=1) to avoid resource contention (ServiceLocator, worker isolates)
• Savepoint release test skipped on SQL Server (RELEASE SAVEPOINT not supported)

Fixed

• Rust FFI E2E: ffi_test_dsn() loads .env and checks ENABLE_E2E_TESTS; invalid stream ID race in tests
• Dart integration test timeouts when running in parallel

0.2.4 - 2026-01-27

Added

• Examples: multi-result, timeouts, typed params, and low-level wrappers

Changed

0.2.3 - 2026-01-27
