v0.7.0 - TBD ​

  • 🆕 New features
    • Package exports with public subpaths chartspire/style.css (stylesheet) and chartspire/bundle.js (UMD for CDN)
    • Optional datafeed subpath: chartspire/datafeeds/binance
    • sideEffects in package.json so bundlers retain CSS when importing the stylesheet
    • Docs: required stylesheet section in Getting Started, API, and Introduction
    • Historical data loading: init, forward, and backward requests use the correct time windows and callback(data, more) so scroll pagination can load older and newer segments
    • New API option dataFeedInitialHistoricalBars to control how many bars are requested on the first historical load (default 500, with validation and an upper cap)
    • Top bar component visibility API: symbolEnabled, topBarIntervalEnabled, indicatorsEnabled, candleTypeEnabled, replayEnabled, multiChartEnabled, chartExportEnabled, settingsEnabled, screenshotEnabled, fullscreenEnabled (all default: true)
    • topBarEnabled option to hide the entire top bar and reclaim its space for chart content (default: true)
    • bottomBarEnabled option to hide the entire bottom bar and reclaim its space for chart content (default: true)
    • leftBarEnabled option to hide the entire left bar (drawing tools) and reclaim its space for chart content (default: true)
    • rightBarEnabled option to hide the entire right bar and reclaim its space for chart content (default: true)
    • DefaultDataFeed rewrite: modular config (http / websocket / auth / security / protocol), shared-channel subscriptions, soft config validation via onError, production auth guidance
    • Interval-native live data: removed client candleAggregation; history and live subscriptions use the chart interval (custom feeds must supply bars at the requested period)
    • Watchlist: stable watchlist subscriber ids, lifecycle-safe subscribe/cleanup (cancel pending timers), optional watchListSubscriptionDelayMs (default 0)
  • 📦 Bundle size (main chartspire-ui.js, gzip)
    • ~321 KB → ~286 KB (~11% smaller): lodash per-method imports, Binance feed split to optional subpath
  • 🔄 Breaking Changes
    • DefaultDataFeed constructor config shape changed (see docs/en-US/defaultDataFeed.md); subscribeSymbol / unsubscribeSymbol require subscriberUID
    • BinanceDataFeed is no longer exported from chartspire; import from chartspire/datafeeds/binance instead
    • StocksDataFeed removed (use DefaultDataFeed for stocks)
    • Renamed intervalEnabled to bottomBarIntervalEnabled for the bottom bar interval selector
    • Renamed drawing bar UI to left bar (chartspire-ui-left-bar, LeftBar component); use leftBarEnabled instead of removed drawingBarVisible
    • Renamed intervalEnabled to bottomBarIntervalEnabled for the bottom bar interval selector
    • Removed paper trading: module, right-bar panel, and docs; dropped paperTradingEnabled, paperTradingMaxTrades, paperTradingPriceTrackingInterval, paperTradingPriceTrackingLogging, paperTradingUseExternalStorage, setPaperTradingChangeCallback, setGetPaperTradingDataCallback, ExternalStorageProvider, and exported PaperTradingData / Order / Position / Trade types; defaultOpenComponents no longer accepts 'papertrading'
    • Removed in-app theme generator: dropped themeGeneraterEnabled, themeUseExternalStorage, setThemeChangeCallback, and setGetThemeDataCallback; custom themes are config-only via themeCustom
  • 🛠 Fixes
    • Interval-aligned from / to range helpers for historical requests (minute through year), replacing incorrect week/month/year span math in adjustFromTo
