I2PChat v1.1.3

I2PChat v1.1.3 — vNext-only live framing

Patch after v1.1.2: removes obsolete pre-vNext live wire framing from ProtocolCodec and the application. I2PCHAT_LEGACY_COMPAT and constructor legacy_compat are gone; peers must speak vNext (MAGIC + PROTOCOL_VERSION). Profile-on-disk migration helpers (migrate_legacy_* for flat .dat layout) are unchanged — they are unrelated to wire format.

Security audits (EN/RU) and docs/PROTOCOL.md are updated accordingly.

Summary

All live chat bytes use the vNext binary codec only. ASCII line-style frames are not parsed. This narrows attack surface and matches the supported product line (no maintained interop target for ancient clients).

Technical

• i2pchat/protocol/protocol_codec.py: drop allow_legacy, _read_legacy_frame, DecodedFrame.is_legacy.
• i2pchat/core/i2p_chat_core.py, PyQt / Textual entrypoints: remove env and legacy_compat.
• Tests: tests/test_protocol_framing_vnext.py — test_ascii_style_stream_hits_resync_limit; legacy-specific tests removed.

Compatibility

Breaking for any hypothetical peer that only emitted pre-vNext frames. Normal v1.x peers are unaffected.

RU

Кратко

v1.1.3 убирает устаревший построчный формат с живого канала; остаётся только vNext. Переменная I2PCHAT_LEGACY_COMPAT и флаг legacy_compat удалены. Миграция файлов профиля на диске (migrate_legacy_*) без изменений — это не про wire.

Совместимость

Разрыв только для гипотетического пира без vNext; обычные пиры v1.x не затронуты.
