# Motoko compiler changelog

## 1.10.0 (2026-06-19)

* motoko (`moc`)

* feat: M0218 ("redundant `stable` keyword") now ships a machine-applicable edit, so `mops check --fix` removes the explicit `stable` keyword on fields of a `persistent actor` (#6175).

* feat: Permitting destructuring patterns against actor types: `let { foo } = a`, `func g({foo} : actor T) {}`, etc. (#6149).

* feat: `/// @deprecated M0235 <message>`: the caffeine deprecation warning (M0235) can now carry a free-text message, rendered as a `note:` sub-diagnostic at every use site. M0154 free-text deprecation messages now render the same way (#6153).

* perf: Multi-value Wasm codegen is now _on by default_, `--no-experimental-multi-value` flag disables (if not desired) (#6165).

* bugfix: M0237 (implicit argument can be omitted) only fires now when the suggested removal preserves the same type instantiation. Previously the edit could be rejected (M0098) (#6166).

* bugfix: M0236 dot-notation suggestion no longer fires for literal receivers: the `lit.f()` rewrite could misparse (`-1.1.isNaN()` → `-(1.1.isNaN())`), mis-lex (`0xff.abs` as a hex float), or fail to type-check when it lost a literal coercion (`Blob.isEmpty("\00")` → `"\00".isEmpty()`) (#6173).

* bugfix: M0236 dot-notation suggestion no longer fires when the receiver cannot be inferred or would infer to a different type causing the call to resolve to a different function (#6177).

* bugfix: Implicit argument derivation now resolves type variables that occur only in a covariant result position (e.g. JSON-style decoders `Text -> ?T`). Previously such a variable was solved to `None` (bottom), so the implicit had to be passed explicitly (#6186).

* bugfix: Diagnostic columns now count Unicode codepoints (matching editor displays and `rustc`), and JSON diagnostics gain `byte_start`/`byte_end` for encoding-independent edit anchors. Previously `mops check --fix` over-deleted on multi-byte lines (e.g. `Char.toNat32('京')` trimmed the trailing `)`) (#6168).

## 1.9.0 (2026-06-02)

* motoko (`moc`)
