v6.0.0

v6.0.0 — Basekick-Labs Fork

Highlights

Performance — 15 optimizations targeting the encode/decode hot paths:

• MarshalAppend API for zero-alloc buffer reuse (-26% vs Marshal)
• Zero-allocation byte-slice reader for Unmarshal (-21% decode, -50% memory)
• map[string]string encode fast path (-15%)
• Skip reflect.Convert for exact map/slice types (-7–8%)
• Inline hasNilCode for byte-slice reader (-2–4% decode)
• Replace goroutine-per-type value pool with sync.Pool (fixes goroutine leak)
• Pool sorted map keys, rec buffers, OmitEmpty slice elimination

Bug Fixes — 12 fixes for correctness and safety:

• OOM protection: cap slice/map allocations at 1M elements
• Float-to-integer decode with NaN/Inf/overflow validation
• Non-string map key support in interface{} decode
• TextUnmarshaler wire format detection (str vs bin)
• Unexported field handling in omitempty struct emptiness
• Custom error type preservation, reflect.Value marshal, unaddressable interface decode
