1. Release Notes

Release notes record what changed in Fractal Chart as the app develops. Each release gets its own page under this section, summarizing what was added, changed, fixed, or removed.

Versioning

Releases are labeled vMAJOR.MINOR.PATCH. While the app is pre-1.0, new features land under minor bumps and fixes under patch bumps; breaking changes may still occur between minor versions.

Releases

• v0.15.0 — Live AI model discovery — the AI assistant's model picker now asks each provider what it currently serves and caches the answer for a day, so a model released today can be selected without an app update. OpenAI, Anthropic, and Google are queried directly from the browser with your key; Bedrock and Vertex go through new server routes that report entitlement failures instead of erroring and keep the built-in list alongside whatever comes back. A refresh button reports why a list did not change, and a stored model the built-in list does not know is kept instead of being reset to the default on reload.
• v0.14.0 — Resizable grid layouts — lets every three-to-six-chart layout be resized by dragging the seam between panes: no divider bar, just a resize cursor and amber highlight on the seam; dragging moves the shared column or row boundary, double-click restores the default proportions, arrow keys nudge a focused seam, and the proportions are remembered per layout and captured in saved workspace layouts. Also fixes saved-layout change detection that depended on stored key order.
• v0.13.0 — Browser market ownership safety — adds default-off fenced ownership for eligible Massive bars and routed chart panes, coordinated pre-authority admission, bounded post-release gate recovery, persistent redacted safety notices, fail-loud market-client context, retrying alert admission, route-scoped readiness with non-market SSR, exact active revision 1.1, redacted protocol-minor diagnostics, recoverable late socket closure, clean reconnect aggregation, and documented bar-derived live paper execution.
• v0.12.1 — Paper trading reliability — hardens no-margin buying power, chronological fills, executable quote provenance, replay rewinds, cross-tab persistence, recovery backups, strict imports, AI/order authorization, telemetry privacy, accessibility, CSV audit fields, Alpaca integration, and automated release gates.
• v0.12.0 — Paper trading — adds a simulated broker on the chart's live feed: market/limit/stop/stop-limit orders, take-profit/stop-loss brackets as real OCO child orders, netted positions with live P&L, an on-chart Buy/Sell trading panel (⌥P) with a one-click trading toggle, order and position lines you can drag, a right-click Trade menu, an Account Manager dock (?panel=paper-trading) with Positions, Orders, History, Trades, Account Summary, and Journal, per-session replay accounts, commission/slippage settings with JSON export/import, AI-assistant tools that read and analyze paper accounts and propose approval-gated orders, and a Dismiss all pill for the shared notification stack. Everything is simulated and stored locally — no real money or brokerage connection.
• v0.11.2 — Replay fit to view — fits every pane's available replay bars into view the moment a start bar is selected, instead of keeping the pre-replay viewport that often left all replayed bars off-screen; playback controls no longer trigger refits, and ending replay fits the live bars back.
• v0.11.1 — Replay indicator warm-up — fixes bar replay starting with only a couple dozen bars of history (the clicked pane and larger-timeframe panes were never backfilled, and the context window was measured in calendar time): every visible pane now gets a 1,000-bar minimum before the start, counted in bars. Also fixes a hydration error on workspace load from the client-only alert toast host.
• v0.11.0 — Invert price scale — adds Invert scale (⌥ I) to the chart right-click menu, flipping a chart upside down per pane: the price pane and its indicators and comparison overlays invert together, while volume and oscillator panes stay upright.
• v0.10.1 — Replay start button fix — fixes the Start replay toolbar button being permanently disabled for every provider since v0.8.14 (its disabled state was derived from replay pane inputs that are intentionally empty while replay is inactive); the button now enables as soon as any visible pane has bars.
• v0.10.0 — CSV data provider — adds CSV as a sixth, local data provider: import your own OHLCV files (one per timeframe, auto-grouped by filename), stored chunked in browser storage and served verbatim per timeframe, with CSV: addressing, symbol search, watchlist quotes, indicators/Pine/backtesting/replay support, and no realtime by design. Also hardens the chart's history-loading guard so scroll-back backfill can't freeze on instant data sources.
• v0.9.1 — Current AI model catalogs — refreshes all five AI provider selectors to current models, migrates known stored selections by tier, preserves exact Bedrock inference-profile IDs, and updates SDK, sampling, and Anthropic thinking-stream compatibility.
• v0.9.0 — Chart context menu & indicator layout sync — adds a compact TradingView-style right-click menu to every workspace chart and copies the explicitly selected pane's indicator configuration across the active layout without changing symbols, timeframes, drawings, replay state, or strategy overlays.
• v0.8.14 — Pine replay stability — restores the v0.8.13 realtime and deep-history improvements with globally serialized cross-pane Pine replay, prompt queued cancellation, and complete publication to recreated indicator series.
• v0.8.13 — Realtime chart performance & replay safety — keeps realtime and deep-history charts responsive through exact Pine tail replay, cooperative full fallbacks, conservative chart deltas, abortable provider streams, and stale-generation/replay/AI isolation.
• v0.8.12 — Replay start selection fix — keeps start-bar clicks responsive while the chart is applying programmatic updates, so replay reliably begins at the selected candle without weakening click suppression for ordinary chart interactions.
• v0.8.11 — History stability & public Piner — keeps historical chart navigation anchored while older bars and related refreshes apply, preserves physical trackpad, pointer-drag, and keyboard intent, moves Piner to public npm at exact version 0.12.0, and tightens alert validation and webhook typing.
• v0.8.10 — Scroll-back crash fix — fixes a crash where scrolling back to load older bars, with certain Pine indicators active and the crosshair hovering the chart, could throw Value is null and blank the whole view. It stems from an open upstream charting-library bug (lightweight-charts#2044) where an earlier series keeps a stale index mapping as the time scale shifts; the indicator renderer now isolates each series' chart update so a transient library error during a scroll-back load can't take down the app.
• v0.8.9 — Pine strategy fidelity: request.security & overlay plots — Pine strategies and indicators track TradingView more closely. request.security now resolves from real data on every timeframe: strategy backtests get the data seam wired for the first time (cross-symbol and lower-timeframe requests were silently na), and same-symbol requests to a non-chart timeframe are fetched instead of degrading to the chart series or resampling one bar late. Strategy overlay plots also render correctly: line plots break at na gaps like TradingView instead of bridging them, futures overlays fetch the futures endpoint, and a self request.security(syminfo.tickerid) sees the real symbol. Bumps piner to v0.8.0.
• v0.8.8 — Strategy plot() overlays on the chart — a backtested Pine strategy now renders its own plot()/plotshape/fill/… outputs on its pane (not just buy/sell markers), with full visual parity to a Pine indicator: the ran strategy source is registered as an ephemeral indicator and drawn through the existing pipeline. Overlays are derived (never persisted), stay out of the legend/editor, and are suppressed during replay.
• v0.8.7 — Buy-&-hold basis fix and intrabar run-up — bumps piner to v0.6.0: buy-&-hold now benchmarks from the strategy's first trade fill instead of always the chart's second bar, and max run-up now matches TradingView's intrabar method (mirroring max drawdown).
• v0.8.6 — Pine strategy metrics from piner — Pine strategy stats (Sharpe, Sortino, CAGR, exposure, per-trade commission/excursions, max drawdown, win rate) now come from piner v0.5.1's own derived metrics instead of a local recomputation, fixing several numbers that previously diverged from TradingView.
• v0.8.0 — Kraken data provider — adds Kraken as a fully integrated crypto provider (spot + perpetual futures) with Binance/OKX feature parity: historical and realtime bars, a tick-driven live price line, symbol search, watchlist, KR: prefix addressing, and no API key required.
• v0.7.0 — User accounts — adds an end-to-end user-account system: sign-up, sign-in, social login (Google/Facebook/Apple), password reset, and an account dashboard for profile, password, active-session, and account management. Sessions are server-managed (opaque HttpOnly cookie, 30-minute idle window, 7-day absolute cap). Also includes a detachable indicator/strategy editor, a landing footer theme toggle, and the production hardening/infra fixes made while bringing auth live.
• v0.6.1 — Chart screenshot timeframe fix — fixes the active-pane snapshot download re-firing on every timeframe change after the first save; the chart now treats an already-issued screenshot request as consumed when it remounts.
• v0.6.0 — OKX data provider — adds OKX as a fully integrated crypto provider (spot + linear perpetual swaps) with Binance feature parity: historical and realtime bars, symbol search, watchlist, OK: prefix addressing, and no API key required.
• v0.5.2 — Live prices & watchlist quotes — adds a tick-driven live price level on the chart (with graceful fallback to the bar-driven line), live polling of watchlist row prices and percent change via bulk provider snapshots, a simpler mobile symbol overlay, and a "report a bug" link on Pine error messages.
• v0.5.1 — Active-pane browser title — the browser tab title now follows the focused pane in a multi-pane layout, showing that pane's symbol and live price instead of always the main route ticker.
• v0.5.0 — Pine Script Engine — integrates a full Pine Script v6 engine (piner): custom indicators and strategies in Pine, all drawing families, request.security, Pine alerts, an on-chart indicator legend, and Pine as the default authoring language.
• v0.4.0 — Alerts — adds a full alerting system: TradingView-style conditions, toast/browser/sound/webhook notifications, background evaluation of indicator alerts, on-chart alert lines, and a triggered log.
• v0.3.0 — Multi-asset classes & Binance futures — adds a provider-orthogonal asset-class model (equities/crypto/futures/forex), Binance USDⓈ-M perpetual futures, symbol search, and an asset-class indicator.
• v0.2.0 — Alpaca data provider — adds Alpaca as a US-equities data provider and renames legacy browser-storage keys.

Publishing a new release
