## Version 24.004
*Date: Mon Apr 24 2023*
**New Features**
- **Indicators can now be favorited.** Indicators can now be favorited by tapping on the star icon to the left of the
indicator name. Favorited indicators will appear at the top of the indicator
list.
- The `items_favoriting` featureset should be enabled. [more info](https://www.tradingview.com/charting-library-docs/latest/customization/Featuresets)
- **Adding two featuresets to hide the right_toolbar or its tabs.** There are 2 new featuresets `hide_right_toolbar` & `hide_right_toolbar_tabs` plus an additional WidgetBar API [changeWidgetBarVisibility](https://www.tradingview.com/charting-library-docs/latest/api/interfaces/Charting_Library.IWidgetbarApi#changeWidgetBarVisibility) to control the right toolbar.
- `hide_right_toolbar` allows you to instantiate the toolbar without showing it in the UI.
- `hide_right_toolbar_tabs` will do the same with the exception of not showing tabs when displaying the right toolbar.
**Improvements**
- **Added a middle band for the RSI indicator.** Unlike on tradingview.com RSI was not presenting the option to plot a middle limit.
- **Indicators favorites can now be defined within widget constructor.** Indicators can now be defined as favorites using the [`favorites`](https://www.tradingview.com/charting-library-docs/latest/api/interfaces/Charting_Library.ChartingLibraryWidgetOptions#favorites) property of the widget constructor options. See [Favorites.indicators](https://www.tradingview.com/charting-library-docs/latest/api/interfaces/Charting_Library.Favorites#indicators) for more information.
- **Add a way to independently clear bar marks/timescale marks.** [`clearMarks`](https://www.tradingview.com/charting-library-docs/latest/api/interfaces/Charting_Library.IChartWidgetApi#clearmarks) method has been enhanced to pass in an option to choose which marks should be cleared on the chart.
- By default behaviour will remain similar and both bar & TimeScale marks will be removed.
- Passing `ClearMarksMode.BarMarks` will only remove bar marks.
- Passing `ClearMarksMode.TimeScaleMarks` will only remove TimeScale marks.
- **`BREAKING CHANGE` Discrepancy in chart style/type methods.** Only TypeScript breaking change as an interface has been renamed to better reflect its purpose.
`SeriesStyle` is now [SeriesType](api/enums/Charting_Library.SeriesType).
**Bug Fixes**
- **load_study_template event is not emitted.** load_study_template event was not emitted when applying a template on the chart.
- **Fixed autosize bug occurring on Chrome iOS when rotating the device.** Workaround fix for a browser bug until Chrome resolves the issue on their side.
- **Fixed the type definitions for a few of the PineJS Std library functions.** [PineJSStd documentation](@api/interfaces/Charting_Library.PineJSStd).
**Documentation**
- **New Key Features article.** We have added the [Key Features](https://www.tradingview.com/charting-library-docs/latest/getting_started/Key-Features) article that lists features supported/unsupported in Charting Library and Trading Terminal.
- **How to connect data via Datafeed API.** We have added a new [tutorial on connecting data via Datafeed API](https://www.tradingview.com/charting-library-docs/latest/tutorials/implement_datafeed_tutorial/).
It will help you implement datafeed and real-time data streaming to Charting Library step-by-step.
**Other**
- **Incorrect watermark property key.** Deprecated `symbolWatermarkProperties` property has now been removed.
Please use [settings_adapter](Widget-Constructor#settings_adapter) with `symbolWatermark` key instead or `applyOverrides` to change values.
## Version 24.003

- **Price Source and Long Description symbol info fields.** Add support for displaying the price source and long description fields from the symbol info.
- To enable the price source first add `symbol_info_price_source` to the list of enabled features. Then it will be shown in the legend, if available. It can be hidden through the legend context menu and the series property dialog.
- To enable the long description first add `symbol_info_long_description` to the list of enabled features. Then it will be shown in the legend, if available. It can be hidden through the legend context menu and the series property dialog.
**Improvements**

- **Last visible bar value in legend for overlay studies.** When `use_last_visible_bar_value_in_legend` featureset is enabled, overlay studies will display the value for the last visible item on the chart. This now matches the behavior for the main series.
- **Fixed zoom behavior for percentage right margin option.** Incorrect zooming behavior has been fixed for zoom buttons appearing on the chart, and the keyboard shortcuts. See `show_percent_option_for_right_margin` [featureset](https://www.tradingview.com/charting-library-docs/latest/customization/Featuresets) for more information.

**Bug fixes**
- [`setUserEditEnabled`](../api/interfaces/Charting_Library.IStudyApi#setusereditenabled) does not hide 3 dots in Legend. [6765](https://github.com/tradingview/charting_library/issues/6765) | [6165](https://github.com/tradingview/charting_library/issues/6165)
widget.activeChart().getAllStudies().forEach(({ id }) => {
console.log(id);
tvWidget.activeChart().getStudyById(id).setUserEditEnabled(false);
});
- setUserEditEnabled(false) should mask all icons except the "eye".
- setUserEditEnabled(true) should restore all the icons.
- `priceFormatter` could previously only be used for main series. `priceFormatter` now applies to secondary series as well.
- `right_toolbar` featureset didn't have a default `on` value.
- Empty time frames at the bottom toolbar if `data_status: endofday`
- Export data doesn’t include projected data.
- Projected data can be included by setting [`includeOffsetStudyValues`](../api/interfaces/Charting_Library.ExportDataOptions#includeoffsetstudyvalues) to `true`.
- `await widget.activeChart().exportData({ includeOffsetStudyValues: true });`
- Highest PineJS.Std function doesn’t work correctly with negative numbers.
- Missing types in bundled definition file. [7445](https://github.com/tradingview/charting_library/issues/7445) | [7446](https://github.com/tradingview/charting_library/issues/7446)

## Version 24.001
**New Features**
- **Adding originalText as an additional field to UndoRedoState.** Event should mention the name of the action in plain English in addition to also being translated to the corresponding language. [UndoRedoState](@api/interfaces/Charting_Library.UndoRedoState#originalundotext)
- **Add the ability to change X-Axis margin % from Chart Properties.** A new [featureset](@docs/customization/Featuresets) has been added `show_percent_option_for_right_margin` that adds additional percentage option to the right margin section of the chart settings dialog.
- **Display rightmost visible value when in percent mode.** A new [featureset](@docs/customization/Featuresets) has been added `use_last_visible_bar_value_in_legend` to show the most recent “global” bar value. When this feature is enabled the rightmost bar in the visible range is used instead.
- **Ability to change on the fly the Currency and Unit label setting.** [currencyAndUnitVisibility API](@api/interfaces/Charting_Library.IChartingLibraryWidget#currencyandunitvisibility)
- **Add simple SSR support.** Allow the library to be imported within a NodeJS context. This improves support for frameworks such as Remix.

**Improvements**
- **Name to be used instead of ticker.** Allow a human friendly name to be returned from [`symbol_search_complete`](@api/interfaces/Charting_Library.ChartingLibraryWidgetOptions#symbol_search_complete).
**Bug Fixes**
- **Incomplete indicators when using Heikin-Ashi.** Indicator line should draw to all the visible data points.
- **Compare study doesn’t save and restore ticker name correctly.** The compare study should work for custom ticker names just like it does for ticker names which match our format (with the colon).
- **VPFR: Right point is automatically moving when dragging start point.** When drawing the VPFR, or moving one of the anchor points, it is expected that the right anchor point should not move one bar further to the right.
- **Selecting Apply Defaults option within chart settings doesn’t work.** Some Settings even if not validated are not restored to their original values when Apply Defaults is selected.
- **Decentralised app browser loading error.** Chart fails to load in wallet apps like MetaMask, Trust & Phantom. Enable the `iframe_loading_compatibility_mode` [featureset](@docs/customization/Featuresets) to enable compatibility with these browsers.
- **When disabled, widget bar still present a significant margin.** Even when there aren't any pages or widget in the right toolbar and IF right_toolbar is disabled, contrary to the drawing toolbar that vanishes the widget bar stays there with the pill button to expand it whereas there isn't anything to expand.
- **Can’t enable header_compare feature without header_symbol_search.**
- Disabling header_symbol_search should only hide the search button
- Disabling header_compare should only hide the compare button
- **Removed section of PostCSS syntax in bundled css files.**
**Other**
- **New Documentation site.** 🎉
- **Add `shape` to TimeScale.** Shape property is described in [TimescaleMark interface](@api/interfaces/Charting_Library.TimescaleMark#shape).
- **Remove magnet icon near cursor.**
## Version 24

- `'left_toolbar', 'header_widget', 'timeframes_toolbar', 'edit_buttons_in_legend', 'context_menus', 'control_bar', 'border_around_the_chart'`
- `chart_style_hilo` featureset is now enabled by default. This adds the High-low option to chart style controls dropdown. This featureset has been available since 1.15 but was previously disabled by default.
- Added typings for custom indicators. Typescript equivalents of our existing examples are available here: [Custom Studies Typescript Examples](../custom_studies/Custom-Studies-Examples).
- [`symbol_search_complete`](../api/interfaces/Charting_Library.ChartingLibraryWidgetOptions#symbol_search_complete) has changed. The function now takes an additional search result object parameter, and returns an additional human-friendly symbol name.
