v0.26.0

Breaking changes

• Add LUB computation for class types (#2594) (4b3b390)
  Binary and ternary expressions now compute and evaluate to the least upper bound of two not identical class type inputs in the absence of a better fitting contextual type. Technically a breaking change, yet likely without noticeable effects on existing code.

Bug fixes

• Defuse assert in lookupPropertyAccessExpression after prior error (82812de)
• Support trailing comma in function type parameters (#2608) (1ff71e5)

Other

• Use DataView in bindings generation (#2599) (a1434b2)

v0.25.2

New features

• Add --uncheckedBehavior to customize the use of unchecked() (#2575) (7a35ff8)

Bug fixes

• Fix lifetime confusion in shadow stack pass (#2596) (d3410f4)

Other

• Integrate Rtrace with ESM bindings (#2595) (0e0a3c1)
• Update GitHub actions badges (280a8ef)

v0.25.1

Bug fixes

• Use constructor signature for class decorators (#2587) (1d0451a)
• Do proper subtype tests in instanceof (#2588) (78b3260)

Other

• Remove unchecked indexed set on normal arrays (#2586) (b3cffa3)

v0.25.0

Breaking changes

• Fix variable initialization checks / revise flow logic (#2578) (6717de0)
  Initialization of global variables sometimes wasn't guaranteed before, allowing unsafe behavior if initialization indeed wasn't performed before access. To mitigate, variables from now on require either an initializer, a primitive type with a trivial default value (typically 0), a nullable type (if a reference, defaulting to null) or otherwise annotation with definitive assignment (i.e. let someObject!: ..., then inserting a runtime check upon access).

Other

• Speed-up signature lookups, make signatures immutable (#2582) (378659a)
• Re-add Windows to CI (#2584) (658b5e8)

v0.24.1

Bug fixes

• Bindings: Expect memory growth when lowering references (#2568) (8ae086d)
• Defuse assert in finishResolveClass (#2567) (cb982b1)

v0.24.0

Breaking changes

• Implicitly inherit from Object (#2559) (688dcd2)
  Constant class ids of String, ArrayBuffer etc. moved one value up, with Object now represented by ID=0.

v0.23.1

Bug fixes

• Simplify compileCallExpression (#2558) (a71f649)

v0.23.0

Breaking changes

• Remove no longer used half of RTTI (#2555) (a565d73)
  RTTI at __rtti_base no longer contains base class ids and now is just type flags.
• Make class fields a special kind of property (#2548) (0fd4db2)
  Element kinds FIELD and FIELD_PROTOTYPE and elements Field and FieldPrototype have been removed. Instead, Property inherit previous Field functionality, indicated by property.isField.

Other

• Fix CI publishing (#2557) (a150a49)
• Add remaining heap type APIs (#2556) (158b6b6)
• Update GitHub actions to most recent versions (#2541) (5d18a71)
• Add heap type utility definitions (#2549) (6b9f71e)
• Move module creation to program (#2550) (625bf0d)
• Expose import maps when generating web template (#2542) (c7970b5)
• Remove superfluous casts in TLSF (#2543) (f0af970)

v0.22.0

Breaking changes

Other

• Report full path when custom runtime is not found (#2538) (0d39f0f)
• Remove local sharing logic (#2540) (8bb4fae)
• Implement preliminary creation of Wasm GC types (#2537) (78b2d1a)

v0.21.7

Bug fixes

• Make field types invariant to guarantee soundness (#2539) (ee6a165)

Other

• Ensure function locals are not in closures (#2533) (a2c1c97)
• Implement non-/nullable type refs in type conversion (#2535) (7bc3b57)
