• Improved lookup and decoding performance:
  • Reduced IPv6 search-tree traversal overhead.
  • Reduced integer, database pointer, and map key decoding overhead.
  • Reduced reflection overhead when decoding records into structs.
  • Reduced reflection overhead for scalar values read through database
    pointers or decoded into Go pointer fields.
  • Reduced slice decoding overhead and temporary allocations when growing or
    shrinking slices.
  • Reduced struct field matching and access overhead, including scalar fields
    in embedded structs.
• Reflection decoding now enforces the 512-level depth limit for scalar values,
  including in DecodePath. Some scalar values at depth 513 were previously
  accepted.
