v5.0.1 — Release Notes

NEW: Security Guards — SQL injection, XSS, path traversal, command injection, LDAP injection, XXE detection, unsafe filename, and open redirect validation. All patterns use FrozenSet for O(1) lookups.

NEW: Format Guards (replaces TurkishGuards) — Geographic coordinates, MAC address, hostname (RFC 1123), CIDR notation, ISO 3166-1 country codes, IANA time zones, BCP 47 language tags, JWT structure, connection strings, and Base64 validation.

NEW: ThrowHelper Pattern — All hot-path guards delegate throwing to a centralized ThrowHelper with [DoesNotReturn] and [StackTraceHidden] for smaller JIT-compiled method bodies and cleaner stack traces.

NEW: Span-Based FastGuard — Email, ASCII, AlphaNumeric, NumericString, MaxLength, ValidGuid, and Finite validators using ReadOnlySpan with zero allocations.

IMPROVED: Thread-Safe Localization — Rewritten with ConcurrentDictionary and AsyncLocal. Now supports 8 languages: EN, TR, DE, FR, ES, PT, AR, JA. Per-request culture scoping via SetCultureForCurrentScope.

IMPROVED: ObjectValidator — Compiled expression caching, CrossProperty validation, conditional When() blocks.

IMPROVED: FluentGuard — Transform() and Default() pipeline methods. All date comparisons use DateTime.UtcNow.

IMPROVED: All exceptions are sealed with ErrorCode and ParameterName properties.

IMPROVED: RegexCache with bounded size (1000), FrozenSet for BusinessGuards currency codes, ICollection.Count optimization in CollectionGuards.

FIXED: AgainstNotAllLowercase was comparing string to itself (always passed).
FIXED: AgainstEmptyCollection was throwing EmptyStringException instead of NullValueException.
FIXED: GuardBuilderExtensions was passing .Value instead of .ParameterName.

BREAKING: Validate.Object renamed to Validate.For. FastGuard.Guid renamed to FastGuard.ValidGuid. TurkishGuards removed.
