v0.20.0

0.20.0 - 2026-09-30

Highlights: offline phone/LID resolution, confined uploads, authenticated media retries, and chat-state commands alongside sync.

• Contacts: add offline contacts resolve for verified phone/LID pairs, with explicit unresolved results and read-only access alongside sync. Thanks @tsavo-at-pieces (#458).
• Send: add opt-in WACLI_MEDIA_ROOTS upload confinement, including symlink-aware CLI validation and confined file reads in sync daemons. Thanks @tsavo-at-pieces (#459).
• Media: recover authenticated retry uploads without reusing stale ciphertext hashes, while retaining HMAC, plaintext digest, and size verification. Thanks @danielfadul1-pixel (#462).
• Chats: delegate archive, pin, mute, and their inverses to a running sync without blocking the send queue, while preserving caller deadlines. Thanks @nicolasbiondic (#454).
• History: retry unanswered one-to-one backfill with the chat’s verified alternate phone/LID identity and reuse the identity that responds. Thanks @tsavo-at-pieces (#457, #444).
• Sync: enable bounded primary-device rerequests for eligible decryption failures and report unreadable messages with accurate recovery caveats. Thanks @zarmat99 (#441).
• Sync: recover collections that require explicitly empty app-state keys while preserving ordinary key delivery and one-shot chat-state writes. Thanks @jzmudzinski (#443).
• Sync: apply this account’s ordinary read receipts to local unread state so chats read on the phone are reflected locally with read receipts enabled. Thanks @zarmat99 (#439).
• Sync: reuse group information and participant snapshots instead of requesting them twice per message; invalidate on group changes and reconnects, and retry failed snapshot writes. Thanks @zarmat99 (#447).
• Sync: enforce caller deadlines for queued delegated operations even without send spacing, and warn against retrying ambiguous timeouts. Thanks @tsavo-at-pieces (#456, #446).
• Store: avoid scanning the full search index on open and sorting entire phone/LID histories for limited message reads. Thanks @zarmat99 (#455).
• Tests: compile store tests on Windows and isolate account tests from the real Windows home directory; keep both regressions in the normal gate. Thanks @parth-garg01 (#452, #448, #449).
• Dependencies: update pnpm to 12.8.1 and refresh Google API/RPC protocol modules after the 48-hour cooldown, preserving runtime minimums.
• Dependencies: update gRPC tooling dependencies and pnpm to eligible minor releases while retaining the Go/Node minimums and 48-hour package cooldown.
