0.6.27

• motoko (moc)

  • Importing modules by relative path is now more robust (#3215).
  • Performance: persisting stable variables to stable memory is now
    performed in streaming fashion, reducing heap consumption and
    copying during an upgrade (#3149).
  • Performance: local 32- and 64-bit numeric values are now stored in
    using unboxed form when possible (thanks to nomeata) (#3207).

• motoko-base

  • Fixed a bug in Trie.filter (and Trie.mapFilter) which could
    lead to missing matches in some cases (dfinity/motoko-base#371).

0.6.26

• motoko (moc)

  • Performance: inline prim-wrapping functions (thanks to nomeata) (#3159)
  • Improve type pretty printer to mirror type parser (avoids producing unparseable stable variable signatures) (#3190)
  • Adds new flag --omit-metadata to omit certain metadata sections from actor (and actor class) Wasm (#3164)
  • Performance: avoid redundant heap allocation when deserializing compact Candid int and nat values (#3173)
  • Added a primitive to obtain stable variable memory footprint (#3049)

• motoko-base

  • Fixed the 32-bit range limitation of Hash.hash: Nat -> Nat32 and
    deprecate most functions in Hash (dfinity/motoko-base#366).
  • Add List.toIter (thanks to hoosan) (dfinity/motoko-base#336).

0.6.25

• motoko (moc)

  • bugfix: fix bogus elision of type constructors sharing names with primitive types in --stable-types section and .most file (#3140)

0.6.24

• motoko (moc)

  • bugfix: fix bogus identification of distinct type constructors
    in --stable-types section and .most file (#3140)

0.6.23

• motoko (moc)

  • bugfix: fix pretty printing of (stable) types and #3128 (#3130)

    • Collect constructors transitively before emitting a .most file.
    • Modifies type pretty printer to produce well-formed types and stable type signatures.

0.6.22

• motoko (moc)

  • Fix: remove bogus error when transitively importing module with
    selective field imports (#3121)
  • Fix: Treating eponymous types from separate candid files (#3103)

• Various reports from CI are now pushed to
  https://dfinity.github.io/motoko (#3113)

0.6.21

• motoko (moc)

  • Emit new ICP metadata custom section 'motoko:compiler' with compiler release or revision in UTF8 (e.g. "0.6.21"). Default is icp:private (#3091).
  • Generalized import supporting pattern matching and selective field imports (#3076).
  • Fix: insert critical overflow checks preventing rare heap corruptions
    in out-of-memory allocation and stable variable serialization (#3077).
  • Implement support for 128-bit Cycles-API (#3042).

• motoko-base

  • ExperimentalInternetComputer library, exposing low-level, binary call function (a.k.a. "raw calls") (dfinity/motoko-base#334, Motoko #3806).
  • Principal.fromBlob added (dfinity/motoko-base#331).

0.6.20

• motoko

  • Implement support for heartbeat system methods (thanks to ninegua) (#2971)

• motoko-base

  • Add Iter.filter : <A>(Iter<A>, A -> Bool) -> Iter<A> (thanks to jzxchiang1) (dfinity/motoko-base#328).

0.6.19

• motoko-base

  • Fixed a bug in the RBTree.size() method.

0.6.18

• moc

  • Add runtime support for low-level, direct access to 64-bit IC stable memory, including documentation.
  • Add compiler flag --max-stable-pages <n> to cap any use of ExperimentalStableMemory.mo (see below), while reserving space for stable variables.
    Defaults to 65536 (4GiB).

• motoko-base

  • (Officially) add ExperimentalStableMemory.mo library, exposing 64-bit IC stable memory

• BREAKING CHANGE (Minor):
  The previously available (but unadvertised) ExperimentalStableMemory.mo used
  Nat32 offsets. This one uses Nat64 offsets to (eventually) provide access to more address space.
