v0.1.16

Overview

A patch release fixing a gate false positive on short, allocator/dynamic-linker-heavy benchmarks, and unifying the workspace onto one syn major version after a dependency update pulled in a second. No public API changes.

Issues fixed

• walltime gate false-fails on short benchmarks whose instruction-counter jitter lands just past the flat 0.5% cutoff, even with an unchanged fingerprint and identical allocs/bytes (#93, #94)

Notes

Short benchmarks whose instruction count is dominated by allocator or dynamic-linker overhead could fail the walltime gate on ordinary counting jitter: a roughly 20K-instruction bench moving by 106 instructions is a larger share of its own count than the same jitter is for a benchmark with millions, so the flat 0.5% cutoff that corroborates a genuine regression missed it by a fraction of a percentage point even with fingerprint, allocs, and bytes unchanged. counters_flat_on_unchanged_code() now also accepts a fixed 150-instruction floor alongside that percentage, wide enough to absorb the jitter on small benchmarks while staying negligible above roughly 30K instructions, where the percentage still governs.

linkme 0.3.37 moved its proc-macro implementation onto syn 3. soothfast-macros now targets syn 3 as well, so the workspace's two proc-macro crates share one major version instead of leaving cargo-deny's duplicate-version check to reject the split.

Dependencies

• linkme 0.3.36 to 0.3.37 (#85)
• syn 2 to 3 for soothfast-macros, to keep cargo-deny's duplicate-version check passing after that bump (#96)
