Status

The current formal release is Norm 0.24. This page describes the current toolchain. See the Language Reference for long-term language rules and the version index for per-release delivery records.

Maturity labels

Label	Meaning
Stable	Part of the current release contract, with automated acceptance
Experimental	Implemented, but its public shape may still change
Internal	Used inside the toolchain without a promised public entry point
Planned	A documented design or direction that cannot currently be used

Language

Capability	Status	Source of truth
Class, Value, Interface	Stable	Object model
Data enums and exhaustive switch	Stable	Enum and switch
Nullable types, ?., ??, and control-flow narrowing	Stable	Type system
Generic types, functions, methods, and bidirectional inference	Stable	Type inference
Lambdas, function values, and declaration references	Stable	Advanced function rules
Extension functions	Stable	Function reference
ref<T> and lexical lifetimes	Stable	Reference rules
Class<T> and typed declaration references	Stable	Declaration references and reflection
Annotations, @Document, and typed interceptors	Stable	Annotation specification
Packages, modules, and cross-file visibility	Stable	Module system
Typed string interpolation	Stable	Literals
for with break value and else in a value position	Planned	Loop design; the current parser rejects Integer result = for ...
// and /* */ source comments	Planned	The current lexer treats these markers as operator tokens

Standard library

Area	Status
Core types, collections, Unicode text, Math, Time	Stable
Streaming I/O, filesystem, and resource lifetimes	Stable
HTTP client	Stable
Command-line parsing, application runtime environment, standard streams, and subprocesses	Experimental

See the standard library overview for delivered modules. The source and acceptance programs define public entry points.

Tooling

Capability	Status
CLI with bundled Java runtime and JVM development entry	Stable
Formatting, diagnostics, completion, signature help, and hover	Stable
Go to definition, find references, prepare rename, and rename	Stable
Read-only navigation of standard library source	Stable
Official VS Code VSIX	Stable
Debugger	Planned
Online playground	Planned

Known boundaries

• Automatic serialization currently handles value only.
• private has a source-file boundary.
• Generic parameters remain invariant; raw types are unsupported.
• References cannot be stored in fields, containers, generic arguments, return types, or lambda captures.
• There is currently no HTTP server, debugger, or online execution environment.

Adoption decisions should use the latest implementation contract and actual acceptance programs.
