v0.4.0

Added

TDS 7.3 Protocol Support (SQL Server 2008/2008 R2)

• TdsVersion::V7_3A constant for SQL Server 2008
• TdsVersion::V7_3B constant for SQL Server 2008 R2
• Connection string option TDSVersion (or ProtocolVersion) to specify TDS version
• Config::tds_version() builder method for programmatic configuration
• TdsVersion::parse() for parsing version strings ("7.3", "7.3A", "7.3B", "7.4", "8.0")
• TdsVersion::sql_server_version_name() for human-readable SQL Server version names
• TdsVersion::is_tds_7_3() and TdsVersion::is_tds_7_4() helper methods
• TdsVersion::is_legacy() to detect TDS 7.2 and earlier
• TdsVersion::supports_date_time_types() for feature detection
• Version negotiation logging during connection

Testing & CI

• Comprehensive version compatibility test suite (19 tests)
• SQL Server version detection tests

Changed

• BREAKING: Config struct marked #[non_exhaustive]
  • Use Config::new(), Config::default(), or builder methods to construct
  • Allows future field additions without breaking changes
• TdsVersion::Display now shows correct format (e.g., "TDS 7.3A" instead of "TDS 7.10")
• Default TDS version is V7_4 for broad compatibility with SQL Server 2012+
• Setting TdsVersion::V8_0 automatically enables strict_mode

Fixed

• Justfile confirm syntax compatibility with just 1.45+
• Semver check is now advisory for pre-1.0 releases (breaking changes allowed in 0.x.y)
