Nyash Project – Changelog (Work in progress)

This changelog tracks high‑level milestones while Core MIR and Phase 12 evolve. For detailed per‑file history, see git log and docs under docs/development/roadmap/.

2025‑09‑06

• Core‑13 flip complete: code/tests enforce Core‑13 minimal kernel. Normalizations (Array/Ref→BoxCall, TypeCheck/Cast/Barrier/WeakRef unification) are ON by default via env (NYASH_MIR_CORE13=1). New tests validate normalization.
• Docs synced: step‑50 marked done; DEV quickstart points to Core‑13 reference.

2025‑09‑04

• Phase 12.7‑A complete: peek, continue, ? operator, lambda, field type annotations. Language reference updated.
• Phase 12.7‑B (basic) complete: parser‑level desugaring for |>, ?., ??, +=/-=/*=/=, .. behind NYASH_SYNTAX_SUGAR_LEVEL.
• Docs: language reference and Phase 12.7 README updated to reflect basic completion; extensions tracked under gated plan.
• MIR Core migration: previously enforcing Core‑15 during transition; superseded by 2025‑09‑06 Core‑13 flip.

2025‑09‑03

• Nyash ABI TypeBox integration stabilized across core boxes; differential tests added; loader defaults adjusted (builtin + plugins).

Notes

• Core‑13 is canonical minimal kernel. Historical Core‑15 notes remain under docs/development/roadmap/ for reference.
• Phase 12.7‑B desugaring is gated by NYASH_SYNTAX_SUGAR_LEVEL; tokenizer additions are non‑breaking.
