Release v4.184.0

Text rules can now say what they mean: contains, not contains, starts with and ends with are first-class rules, and the lookaround patterns Studio generated for them work again instead of being refused.

Added

• Concept and command rules contains "x", not contains "x", starts with "x" and ends with "x" on text values. They compare UTF-16 code units ordinally, an absent value passes, and they are written to the executable model in a new ESM version; models that do not use them keep their bytes and version. See Commands. (#810)
• Public pattern admission checks PortableMatchPattern.Check(pattern) in .NET and checkPortableMatchPattern(pattern) in @cratis/screenplay-compiler. They report whether a matches pattern is admitted, deprecated, refused or invalid, with the diagnostic code, the construct and its offset, a suggestion, and the first-class replacement for a Studio pattern. (#810)

Changed

• matches patterns in the exact shapes Studio generated for equals, not equals, contains, not contains, starts with and ends with (both the $ and the (?![\s\S]) forms) now bind as the matching first-class rule with warning PLAY0787 and a quick fix, instead of failing with PLAY0699. Executable models already holding these patterns evaluate them as the first-class rule. Every other lookaround is still refused. (#810)
