This release contains deprecations

Deprecations​

@typespec/compiler​

  • #2910 Deprecate @projectedName decorator. @encodedName should be used instead.

    Example:

    -@projectedName("json", "exp")
    +@encodedName("application/json", "exp")

  • #3094 Deprecate @knownValues decorator. Use a named union of string literal with a string variant to achieve the same result without a decorator

    Example:

    -enum FooKV { a, b, c}
    -@knownValues(FooKV)
    -scalar foo extends string;
    +union Foo { "a", "b", "c", string }
