Release Notes

sebastienros/jint (Jint)

v4.16.2

Jint 4.16.2 is a maintenance release from the 4.x branch: correctness and conformance fixes backported from main, and nothing that changes an existing API or an existing default. If you are on 4.16.1 it is a drop-in update — every public signature is the one 4.16.0 shipped, on all five target frameworks, and the per-framework snapshots in Jint.Tests.PublicInterface/Verify/ are unchanged. main remains 5.0.0 development; what is coming there is recorded as it lands in docs/v5-migration.md.

Highlights

Failures that used to end the process, or never end. A native error raised while a call's arguments are being evaluated is propagated instead of leaving an empty value behind, which on 4.16.1 could recurse until the process died — decodeURIComponent on a malformed sequence was enough (#​4009). Native recursion and the forwarding paths through bound functions and proxies are guarded so a deep native chain raises a catchable error (#​4007). A module graph too deep to link raises an error the host can catch instead of overflowing the stack (#​3548). Temporal and Intl parsing cannot throw an uncatchable RegexMatchTimeoutException because the machine was busy (#​3543), a Temporal difference past a calendar's range raises RangeError instead of spinning forever (#​3555), and the process-wide Intl culture cache and Temporal zone cache are read-only and bounded, with a rejected zone no longer remembered — closing a script-driven unbounded growth (#​3546).

Generators and built-ins, step by step. A yield* delegation reached again by a loop both re-delegates and keeps its place: countdown(3) in a loop no longer hangs, and a delegating generator no longer returns the memoized first result (#​3545). Array.prototype.map and slice hand a @@species constructor the length ToLength produced, and a non-callable map argument is a TypeError (#​3547). A trailing NUL pads neither a numeric string nor an array index (#​3552). A removed property slot is a tombstone rather than a free slot to reuse, so enumeration order survives a delete-and-readd (#​3318), and LengthOfArrayLike no longer clamps through a uint overload (#​3328).

Interop that answers for the right engine. Two engines in one process no longer decide each other's conversions and operators (#​3559), a host type converter's answer stays with the engine whose converter gave it (#​3563), and a value the host registers on a ShadowRealm — and the members its wrapper builds eagerly — belong to that realm (#​3557). Realm construction state is restored after nesting or a failure (#​4008). Overload selection is by the arguments in hand: an operator overload is chosen that way (#​3611), a params overload is chosen by the array's element type with a failing element declining rather than throwing (#​3782), an overload the argument cannot bind to is not a match, and a host operator that throws reports what it threw (#​3554). An index on a wrapped host collection is one property however it is spelled, and a member filter that hides the indexer hides it (#​3562); a read-only host collection refuses a write with a JavaScript TypeError rather than the CLR's NotSupportedException (#​3556).

Internationalization and Temporal. The Persian calendar extends into proleptic years on its 33-year cycle, so the ends of Temporal's range land in the right Persian year (#​4006); a calendar that counts Gregorian months writes their names (#​3612); and a -u- extension carrying more than one key is read whole (#​3613).

Errors. Only a string-valued stack counts as a pre-existing stack when a JavaScriptException is built, so an accessor or non-string stack on a thrown object no longer breaks error reporting (#​3677, reported by @​jeske).

Every change was verified failing-first against the unfixed branch on both .NET Framework and .NET 10, and the release was gated on a paired SunSpider and Dromaeo comparison against 4.16.1 on an idle machine: no row regressed outside run-to-run noise, most run 1–4 % faster.
