What shipped, and when.

Syntax v2 is the default

25 August 2026 · #38

The biggest change in the language's life. .luke and .lk files now use the technical surface — fn, let, struct, braces and operators — instead of the conversational one.

// before
THIS IS FUNCTION add WITH a AS NUMBER, b AS NUMBER GIVES BACK NUMBER DO
  GIVE BACK ADD a AND b
END FUNCTION

// after
fn add(a: float, b: float) -> float {
  return a + b
}

• The whole corpus moved: 118 examples, the standard library, packages and the deployed demo
• luke MIGRATE file.luke rewrites v1 source, marking anything it cannot translate
• Conversational v1 stays available behind --syntax=1 for the deprecation window
• The specification is machine-checked against code generation, so it cannot drift
• Equivalence gates compare v1 and v2 output byte for byte — 10 of 10 normative programs pass

Official editor tooling

19 August 2026 · #37

• A VS Code extension with syntax highlighting, snippets and brace-aware indentation
• Backend publishing documentation for getting a built server onto a real machine
• AGENTS.md, describing how the repository expects automated contributors to behave

Postgres, with Slipstream

13 August 2026

A libpq driver landed with an asynchronous pipelined executor, and then Slipstream — an adaptive sharded executor — became the default after benchmarks showed it winning.

• import std/pg with TLS, pooling and prepared statement caching
• Pipelined dispatch that keeps the socket busy instead of round-tripping per query
• SQLite gained a thread-local pool, a statement cache and WAL pragmas by default

Numbers and methodology in backend benchmarks.

HTTP at ten thousand connections

13 August 2026

• An epoll and kqueue event loop with a handler pool
• Keep-alive, SO_REUSEPORT multi-loop accept, TCP_NODELAY and writev
• Chunked responses, client IP through proxy headers, and graceful shutdown on SIGTERM

httpServe(server, handler, maxConn) is still one line in your source; the tiers are chosen by the compiler.

The frontend track finished

12 August 2026

• Per-axis alignment, declarative breakpoints, grids, scroll containers and wrapping
• Accessibility as language surface: announcements, focus traps and restore, live regions
• Modal semantics, viewport reflow on resize, and Tailwind class pass-through
• Region-minimal painting — a changed cell repaints its region, not the page

Live Graph gets incremental views

12 August 2026

Watched queries stopped re-running in full. Joins, filters and aggregates are now maintained by delta against a change log, which is also what makes time travel possible.

• Keyed join maintenance, including filtered and multi-way joins
• Incremental aggregates, with ranged and function variants
• Resume-from-log so a reconnecting client does not miss events
• Scrubbing backwards and forwards over the log in the browser

Language server, debugger and formatter

12 August 2026

• luke LSP — hover, completion, definition, document symbols, formatting, diagnostics
• luke DAP for editor debugging, and luke DEBUG --break file:line driving gdb on your source lines
• luke DEBUG --inspect dumps reactive cells with their dependency edges
• luke FMT, with a CI gate proving the round trip is byte-stable across every example
