Changelog

0.1.4 — 2026-10-18

Update the default WhatsApp Web version to 2.3000.1050728964, verified against whatsmeow b2b1e71 on 2026-10-18.
Regenerate the protobuf snapshot, including audio stickers, location requests, shared-device contact keys, history restrictions, community settings and new device capabilities. Internal wallpaper colors now follow upstream's fixed32 ARGB representation; new wire fixtures verify the changed types.
Allow UPSTREAM_REF=<commit> in the proto updater for reproducible snapshots, preserve local upstream edits and include all proto wire suites in its checks.

Honor state="false" on incoming prekey messages without replacing or advancing existing Signal sessions, pending aliases or persisted sessions. Consume one-time prekeys only after successful decryption; keep established sessions intact when a stateless message fails authentication.
Prevent receipt, notification and call ACKs from changing the status of a message with the same ID. Only message-class ACKs carry a delivery verdict.

1,101 passing tests and 90.03% maintained-code coverage on Elixir 1.20.4 / OTP 29.1.1. Validation uses local protocol peers, without a live WhatsApp account.
Add authenticated stateless-prekey tests for map and ETS stores, ACK ID collision tests and independent protoc wire fixtures for the October schema.
Verify existing handling of split encrypted frames, malformed stanza tags and group participant_pn aliases without an addressing-mode hint.

Update the default WhatsApp Web version to 2.3000.1047068806, verified against whatsmeow 9ec8f76 on 2026-09-09.
Refresh the generated protobuf modules with additive upstream schema changes for ACP2, newsletters, video, AI, business and device capabilities. These changes extend wire compatibility; they do not introduce new public APIs.
Enforce 90% coverage for maintained code, with the existing exclusion for generated protobuf modules unchanged.

Start the diagnostic WebSocket transport with a valid WebSockex connection callback and close its socket when disconnecting.
Use the configured client version consistently in the diagnostic Noise payload.
Parse decoded binary prekey bundles and preserve device IDs in peer JIDs.
Replace existing message IDs correctly in custom store adapters and migrate legacy message lists without resurrecting deleted messages.
Return an error from ExWapp.Binary.encode/1 for invalid node shapes.
Report invalid media retry keys explicitly and complete session cleanup when a store flush raises, throws or exits.

1,081 passing tests, including authenticated Noise and Signal exchanges, local HTTP/HTTPS and WebSocket servers, persistence recovery and failure injection.
90% maintained-code coverage. Protocol tests run without a WhatsApp account; live interoperability remains dependent on WhatsApp's private protocol.
