Wyn v1.8 is here. This release focused on stability, developer experience, and making the language feel polished enough to ship real software.

Compiler fixes

Over 25 bugs fixed in this release cycle:

• Float + int auto-promotion - 3.14 + 1 just works
• Enum match with bare variants - match c { Red => ... } resolves correctly
• Anonymous closure capture - lambdas passed as arguments capture enclosing variables
• Impl method return types - var c = a.add(b) infers the correct struct type
• Spawn with typed parameters - arrays, structs, and strings pass correctly to green threads
• Array sort fix - was corrupting values due to 32/64-bit mismatch
• File.read on missing files - returns empty string instead of crashing

New: Color module

println(Color.bold("=== My App ==="))
println(Color.red("Error: not found"))
println(Color.green("Success!"))

10 functions: red, green, yellow, blue, cyan, magenta, gray, bold, dim, underline. All return strings, so they compose naturally.
