v0.4.0: Protocol v4 — header-driven sync, tiered engagement, multi-upstream
Protocol v4 sync overhaul: - Slim PullSyncRequest: per-author timestamps (since_ms) replace full post ID lists Request size O(follows) instead of O(posts). Backward-compatible via serde default. - Tiered pull frequency: 60s ticks, only syncs stale authors (4hr default) Full pull only on first tick (bootstrap). Most ticks skip — no stale authors. - Tiered engagement checks: frequency scales with content age 5min (<72h), 1hr (3-14d), 4hr (14-30d), 24hr (>30d) Single SQL query filters posts due for check. - Header-driven post discovery: ManifestPush triggers PostFetch for missing followed-author posts (capped 10 per manifest). CDN tree = notification system. - Multi-upstream (3 max): composite PK, priority ordering, engagement diffs sent to all upstreams, promote/remove on failure. DB schema: - follows.last_sync_ms — Self Last Encounter per author - posts.last_engagement_ms — last reaction/comment timestamp - posts.last_check_ms — last engagement check timestamp - post_upstream: single-row → 3-row with priority column Lock contention fixes: - get_blob_for_post: 3 locks → 1 - prefetch_blobs_from_peer: lock-free blob checks - fetch_engagement_from_peer: explicit lock release before I/O - serve_post: 4 locks → 2 (eliminated redundant queries) - run_replication_check: 2 locks → 1 - Badge cycle: N+2 IPC calls → 1 (get_badge_counts) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

<p style="margin-top: 0.5rem;"><strong>v0.4.0</strong> (planned): Protocol v4 — header-driven sync. ManifestPush as primary post notification. Slim PullSyncRequest (per-author timestamps, not full post ID list). Tiered engagement checks (5min/1hr/4hr/24hr by content age). Multi-upstream (3 max) with fallback chain. Auto-prefetch followed authors <90d. Self Last Encounter per-author tracking. Encrypted-but-not-for-us CDN caching. Serial engagement polling. ~90% bandwidth reduction for established nodes.</p>

<p style="margin-top: 0.5rem;"><strong>v0.4.0</strong> (2026-03-21): Protocol v4 — header-driven sync. ManifestPush as primary post notification. Slim PullSyncRequest (per-author timestamps, not full post ID list). Tiered engagement checks (5min/1hr/4hr/24hr by content age). Multi-upstream (3 max) with fallback chain. Auto-prefetch followed authors <90d. Self Last Encounter per-author tracking. Encrypted-but-not-for-us CDN caching. Serial engagement polling. ~90% bandwidth reduction for established nodes.</p>
|
||||
<p><strong>v0.3.6</strong> (2026-03-20): Active CDN replication — all devices proactively replicate recent posts to peers (desktops > anchors > phones priority). ReplicationRequest/Response (0xE1/0xE2). Device roles (Intermittent/Available/Persistent) advertised in InitialExchange. Bandwidth budgets: replication (pull to cache) + delivery (serve requests), hourly auto-reset, phones 100MB/1GB, desktops 200MB/2GB, anchors 200MB/1GB. Cache management: 1GB default, configurable, eviction cycle activated with share-link priority boost. Engagement distribution fix — BlobHeader JSON rebuilt after diff ops. Tombstone system — deleted reactions/comments tombstoned, propagate via pull sync. Persistent notifications via seen_engagement/seen_messages tables. DOS hardening: fan-out cap (10), prefetch cap (20), downstream registration cap (50), delivery budget enforcement. Pull preference reordered: non-anchors first. Network indicator — header dot (black/red/yellow/green) + capability labels. Tab badges — contextual counts (new posts, engagement, online, unread). Message read tracking on open/close/send. Stats bar removed.</p>
|
||||
<p><strong>v0.3.5</strong> (2026-03-20): Private blob encryption — attachments on encrypted posts (Friends/Circle/Direct) now encrypted with same CEK as post text; public blobs unchanged; CID on ciphertext. Blob prefetch on sync — attachments eagerly fetched after post pull for offline availability. Crypto refactoring — extracted reusable primitives (encrypt/decrypt_bytes_with_cek, unwrap_cek_for_recipient, unwrap_group_cek). Intent-based post filtering — feed/myposts/messages filter on intentKind instead of encryption state. Blob decryption API (get_blob_for_post). Download filename sanitization. Encrypted receipt & comment slots — private posts carry noise-prefilled encrypted slots in BlobHeader for delivery/read/react receipts and private comments; CDN-propagated as opaque bytes; slot key derived from post CEK; 3 new BlobHeaderDiffOps (WriteReceiptSlot, WriteCommentSlot, AddCommentSlots). Message UI — DM delivery indicators (checkmark/double/blue/emoji), auto-seen on view, react button on messages.</p>
|
||||
<p><strong>v0.3.4</strong> (2026-03-18): Comment edit & delete with trust-based propagation. Native notifications via Tauri plugin (messages, posts, reactions, comments). Forward-compatible BlobHeaderDiffOp::Unknown variant. Following Online/Offline lightbox. Comment threading scoping fix. Dropdown text legibility fix. Mobile hamburger nav for website.</p>

|

<ul>
|
||||
<li><strong>Protocol v4: Header-driven sync</strong> — Major sync protocol revision. ManifestPush now triggers post discovery from CDN tree headers. Bandwidth reduced ~90% for established nodes.</li>
|
||||
<li><strong>Slim PullSyncRequest</strong> — Per-author timestamps replace full post ID lists. Request size drops from O(posts) to O(follows). Backward-compatible with v3 peers.</li>
|
||||
<li><strong>Tiered pull frequency</strong> — Pull cycle checks every 60s but only syncs stale authors (4-hour default). Full pull only on first tick. Most ticks do nothing.</li>
|
||||
<li><strong>Tiered engagement checks</strong> — Engagement polling frequency scales with content age: 5min (<72h), 1hr (3-14d), 4hr (14-30d), 24hr (>30d). Single SQL query filters due posts.</li>
|
||||
<li><strong>Header-driven post discovery</strong> — ManifestPush triggers PostFetch for missing followed-author posts (capped at 10 per manifest). CDN tree becomes the notification system.</li>
|
||||
<li><strong>Multi-upstream (3 max)</strong> — Posts track up to 3 upstream sources with priority ordering. Engagement diffs sent to all upstreams. Fallback on upstream failure.</li>
|
||||
<li><strong>Lock contention fixes</strong> — 6 hot paths optimized: get_blob_for_post (3→1 locks), prefetch (lock-free blob checks), serve_post (4→2 locks), badge cycle (N+2→1 IPC call).</li>
