[0.2.0] - 2026-07-11

Added

  • Raptorq.StreamingDecoder for ergonomically ingesting symbols one by one and automatically decoding when sufficient symbols are collected.
  • Raptorq.encode/3 to support automatic zero-padding and chunking of source payloads that are not perfectly divisible by the symbol size.

Changed

  • Raptorq.encode/2 now strictly enforces that the source data length is an exact multiple of k (to prevent hidden padding bugs). For automatic padding, use encode/3.
  • Replaced the README performance estimates with accurate, real-world :timer.tc benchmarks for the pure Elixir 5-phase sparse solver.

[0.1.0] - 2025-05-16

Added

  • Initial release of the RaptorQ codec (RFC 6330).
  • Raptorq.encode/2 to compute intermediate symbols for a block of K source symbols.
  • Raptorq.repair/3 to generate encoding symbols for arbitrary ISIs.
  • Raptorq.decode/3 to recover source data from any K' distinct symbols.
  • Dense reference solver (Raptorq.Solver) and O(L²) 5-phase sparse solver (Raptorq.Solver5).
  • Precomputed tables in priv/ (SIOP, Deg, OCT_LOG/EXP, V0–V3).
