v2.2.7

• thread safety for parse and tokenize operations,
• fix for multiple attributes applied to a single field (related to allowed quantity).

v2.2.6

• expressions are culture insensitive,
• fix for annotations in derived types.

v2.2.5

• improved unary boolean negation handling:
  • parsing logic adjusted to slightly modified grammar where negation can also be applied to operands joined by relational operators (EQ and NEQ),
  • restriction applied to negation operator specifying that it can only by used with boolean type operands.

v2.2.4

• parsing verbosity related to errors detection improved:
  • erratic code location provided,
  • operands applicability constraints added to the parser,
  • minor changes in exception handling (readability improved - no information overhead),
  • etc.
• 2 signatures for Date function provided,
• MemberName extraction workaround - done basically for older versions of MVC (before version 5) where there was a bug related to the fact that member name was given as null in the validation context (it is correctly provided to ValidationResult now, if DisplayAttribute is present),
• XML documentation comments revised,
• code cleanup.

v2.2.3

• string literal cleanups:
  • double-quoted string literals deprecated - single-quoted are the only allowed from now,
  • fixed interpretation of special characters (e.g. regex patterns are correctly interpreted at both client- and server-sides when passed as functions parameters, etc).
• interpretation of plus and minus signs of numeric tokens moved from lexer to parser, thus spaces are not required between operands and operator as before ('1+2' is valid construction now even without spaces inside, in addition consecutive plus and minus signs are unified - as C# and JavaScript do),
• IE8 support (older IE versions not tested),
• few secondary fixes (unicode-related compatibility of built-in regexes between client- and server-sides preserved, etc).

v2.2.2

• null-safety provided for almost all relevant toolchain methods,
• parser fix related to processing of func tokens.

v2.2.1

• underscores supported by func tokens.

2.2.0

• toolchain extended,
• multiple annotations of the same type can be now applied for a single field or property,
• custom JSON formatting is discarded for client validation rules (since EA relies on specific JSON formatting),
• dates equality comparison fix at client side (compare milliseconds instead of date objects),
• non-standard date formats can be handled by overriding default parsing mechanism.

v2.1.2

• assemblies signed (the private key is not included in the public repo - by default, assemblies built from the sources in debug mode will not be signed, and the key is not needed for successful compilation),
• little optimizations:
  • first-time validation speedup - parsing logic is invoked inside ASP.NET MVC validators at application startup, and compiled lambdas are immediately cached for later usage,
  • not entire enumerated types, serialized to json, are sent to client as previously, but only the items used by the expression.
• improved errors handling with more meaningful exception messages, e.g. while naming collision is detected,
• improved arithmetic operations support,
• entire spectrum of enum types supported,
• constants supported.

v2.1.1

• types from current domain loaded silently (reflection issues handled when collecting types from inaccessible assemblies, e.g. non-existing, broken or those to which user has no access),
• relational and arithmetic operators work with enums,
• types conversion improvements.
