Full Changelog: https://github.com/ericlewis/libpo32/compare/0.2.1...0.3.0

Fixed

• ARCHITECTURE.md now lists po32_patch_import.c as a core module.
• C_API.md now documents PO32_ERR_PARSE, the streaming modulator API, and po32_patch_parse_mtdrum_text(...).
• README.md now lists the po32_example command in the examples table.

Changed

• Expanded test coverage across all src/ and examples/ files, covering error paths, edge cases, and previously untested branches in the import parser, synth renderer, frame builder, and example programs.
• Add license scan report and status by @fossabot in https://github.com/ericlewis/libpo32/pull/2
• fix(import): bound exponent parsing and add helper coverage by @ericlewis in https://github.com/ericlewis/libpo32/pull/3

New Contributors

• @fossabot made their first contribution in https://github.com/ericlewis/libpo32/pull/2

Full Changelog: https://github.com/ericlewis/libpo32/compare/0.2.0...0.2.1

This release focuses on correctness and usability for real PO-32 pattern transfers.

Fixed

• Corrected pattern packet encode/decode to match the verified on-device wire layout: 16 trigger bytes, then 16 morph pairs, repeated four times.
• Fixed pattern trigger handling to follow verified wire semantics: a zero low nibble means an empty step, and active triggers require a non-zero fill-rate nibble.
• Resolved cases where patterns decoded correctly locally but landed on the wrong steps or instruments on real PO-32 hardware.

Added

• High-level pattern builder helpers:
  • po32_pattern_init(...)
  • po32_pattern_clear(...)
  • po32_pattern_set_trigger(...)
  • po32_pattern_clear_trigger(...)
  • po32_pattern_clear_step(...)
  • po32_pattern_set_accent(...)
• po32_pattern_step_t and decoded po32_pattern_packet_t.steps[] as the primary pattern editing surface.
• po32_decode_capture example for decoding transfer WAVs into normalized frame dumps, per-packet payloads, and compact pattern summaries.
• Starter presets in po32_pattern_editor for quick hardware-safe pattern export.

Changed

• po32_pattern_packet_t no longer exposes raw trigger_lanes[]; pattern data is edited through decoded step entries and builder helpers.
• The core is fully freestanding C99, with self-contained replacements for libc-dependent helpers.
• Release docs were revised for clearer protocol, API, and usage documentation.

Verification

• ./scripts/check-version-sync.sh
• ./scripts/ci-verify.sh core
