Appendix B — Version history

This specification defines the language at its current version, v0.109 (§1.1). Bynk is pre-1.0 and developed in small, spec-first increments; while it is pre-1.0, an increment may change behaviour. (v0.59 is tooling — bynkc test --format json — with no language-surface change; the language is unchanged from v0.55, the last increment that touched it.)

This specification is the single source of truth for the shipped language. The standalone development instalments that preceded it — the bynk-mvp-grammar-v0.X.md files and the v0.17 adapters specification — have been retired and removed: they were working snapshots that drifted as ambiguities were resolved during implementation, and a maintained projection of the language is exactly what this document replaces. Their history is preserved in version control; the design decisions they recorded live on as the decision records in design/decisions/.

The per-increment history — the notable change in each version from v0.5 onwards — is the version compatibility & changelog. It is reused here rather than duplicated; this appendix adds only the framing that the specification is authoritative.

Note

The maintenance discipline: a language increment updates this specification (and the generated grammar, diagnostics, and changelog it draws on) and records its language-defining calls as decision records — it does not add a standalone instalment document. This note is informative.
