# Motoko compiler changelog

## 1.12.0 (2026-07-30)

* motoko (`moc`)

* feat: the excess-precision warning (M0266) now also covers `Float` (F64) literals, not just
`Float32`, suggesting the shortest round-trip equivalent (#6261).

* feat: `--stable-baseline <file.most>` with `--enhanced-migration` escalates unexplained
"initial actor requires field" cases to error M0267; fields whose baseline type is a
stable subtype of the required type keep warning M0254 (prototype for legacy→EM
conversions) (#6249).

* feat: `--stable-baseline` also runs the same upgrade check as `--stable-compatible` during
`--check`, so tools can typecheck and verify upgrade safety in one `moc` invocation (#6253).

* fix: refresh the broken docs links in compatibility and stable-memory diagnostics (#6255).

## 1.11.2 (2026-07-22)

* motoko (`moc`)

programs using this identifier will break.
