0.14.14

• motoko (moc)

  • Lazy WASM imports: avoids unnecessary function imports from the runtime, improving compatibility with more runtime versions (#5276).

  • Improved stable compatibility error messages to be more concise and clear during canister upgrades (#5271).

0.14.13

• motoko (moc)

  • Introduce await? to synchronize async futures, avoiding the commit point when already fulfilled (#5215).

  • Adds a Prim.Array_tabulateVar function, that allows faster initialization of mutable arrays (#5256).

  • optimization: accelerate IR type checking with caching of sub, lub and check_typ tests (#5260).
    Reduces need for -no-check-ir flag.

0.14.12

• motoko (moc)

  • optimization: for --enhanced-orthogonal-persistence, reduce code-size and compile-time by sharing more static allocations (#5233, #5242).
  • bugfix: fix -fshared-code bug (#5230).
  • bugfix: avoid stack overflow and reduce code complexity for large eop canisters (#5218).
  • Added the rootKey primitive (#4994).

0.14.11

• motoko (moc)

  • Enhance syntax error messages with examples and support find-references and go-to-definition
    functionality for fields in the language server (Serokell, Milestone-3) (#5076).

  • bugfix: mo-doc now correctly extracts record-patterned function arguments (#5128).

0.14.10

• motoko (moc)

  • Added new primitives for cost calculation:
    costCall, costCreateCanister, costHttpRequest, costSignWithEcdsa, costSignWithSchnorr (#5001).

0.14.9

• motoko (moc)

  • Added new primitives for exploding fixed-width numbers to bytes:
    explodeNat16, explodeInt16, explodeNat32, explodeInt32, explodeNat64, explodeInt64 (#5057).

0.14.8

• motoko (moc)

  • Add random-access indexing to Blob, support special methods get and keys (#5018).

  • Officializing enhanced orthogonal persistence (EOP) after a successful beta testing phase (#5035).

    EOP needs to be explicitly enabled by the --enhanced-orthogonal-persistence compiler flag or via args in dfx.json:

      "type" : "motoko"
      ...
      "args" : "--enhanced-orthogonal-persistence"
    

  • Add support for parser error recovery to improve LSP (Serokell, Milestone-2) (#4959).

  • We now provide a proper motoko-mode for emacs (#5043).

  • bugfix: Avoid generating new Candid types arising from equal homonymous Motoko type (if possible)
    in service definitions (#4309, #5013).

  • bugfix: Provide a more consistent framework for dealing with internally generated type indentifiers,
    fixing caching bugs, e.g. in the VSCode plugin (#5055).

0.14.7

• motoko (moc)

  • Preserve and infer named types both to improve displayed types in error messages, and to preserve function signatures when deriving Candid types (#4943).
    The names remain semantically insignificant and are ignored when comparing types for subtyping and equality.

    For example,

    func add(x : Int, y : Int) : (res : Int) = x + y;

    now has inferred type:

    (x : Int, y: Int) -> (res : Int)

    Previously, the type would be inferred as:

    (Int, Int) -> Int

  • Refine the *.most stable signature file format to distinguish stable variables that are strictly required by the migration function rather than propagated from the actor body (#4991).
    This enables the stable compatibility check to verify that a migration function will not fail due to missing required fields.
    Required fields are declared in, not stable, in the actor's pre-signature.

  • Added improved LSP cache for typechecking (thanks to Serokell) (#4931).

  • Reduce enhanced-orthogonal-persistence memory requirements using incremental allocation within partitions (#4979).

• motoko-base

  • Deprecated ExperimentalCycles.add, use a parenthetical (with cycles = <amount>) <send> instead (dfinity/motoko-base#703).

0.14.6

• motoko (moc)

  • To prevent implicit data loss due to upgrades, stable fields may no longer be dropped or promoted to lossy supertypes (#4970).
    Removing a stable variable, or promoting its type to a lossy supertype by, for example, dropping nested record fields,
    now requires an explicit migration expression.
    Promotion to non-lossy supertypes, such as Nat to Int or {#version1} to {#version1; #version2}, is still supported.

  • Now we detect (and warn for) fields in literal objects and record extensions,
    (as well as public fields or types in object and class) that are inaccessible
    due to a user-specified type constraint (#4978, #4981).

  • We now provide release artefacts for Darwin-arm64 and Linux-aarch64 platforms (#4952).

0.14.5

• motoko (moc)

  • Performance improvements to the default timer mechanism (#3872, #4967).

• documentation (mo-doc)

  • Changed extracted let bindings with manifest function type to appear as funcs (#4963).
