## Version 25

*Date: Mon May 22 2023*

**Breaking Changes**

- **Save and Load Chart Templates.** Add methods to the [save/load adapter](https://www.tradingview.com/charting-library-docs/latest/saving_loading) to support chart templates.
- **Renew design for send order and buy sell buttons.** Renew design for send order and buy sell buttons:
  - Buttons are now rounded
  - Selected item and underline are now black
- **New TV logo.** What is changing:
  - Changing the size, boldness of the text
  - Indentation of the logo from the borders of the chart
- **One row for grid lines settings.** The grid lines settings have been combined into one row.
- **Remove magnet icon near cursor - Reverting feature.** Following reviews this piece of work was reverted.
- **Update Charting Library branding.** Branding font and position is slightly changed.
- **Do not load Euclid font for the branding logo on chart.** The Euclid font will not load if there is an animated logo on the chart.
- **When the chart data is reset, the new request for data will only be for the visible range.** The previous behavior was that when [resetData](https://www.tradingview.com/charting-library-docs/latest/api/interfaces/Charting_Library.IChartWidgetApi#resetdata) was evoked, that the datafeed would be requested to provide data for the entire range of data already loaded for that symbol. The new behavior is that the request is now only for the current visible range. This more closely matches the behavior of the first load. If you require the old behavior then you can disable the `request_only_visible_range_on_reset` featureset.
- **Remove timezone & session breaks section from scale gear menu.** Time zone and Session breaks section has been removed from gear menu.
- **Update chart types icons.** Changed icons for Line, Area and Baseline chart types.

- **Add Data window item to context/legend three dots menu.** Added new item to context/legend three dots menu - "Data window..." with a shortcut. Opens Data Window in the right panel.
- **Add Volume profile indicators on the top of chart series.** Changed the default z-order for Volume Profile indicators and VP drawings. They are now located above the main series.

        console.log(id);
        tvWidget.activeChart().getStudyById(id).setUserEditEnabled(false);
      });

## Version 24.001

**New Features**

**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.

  - Disabling header_compare should only hide the compare button
- **Removed section of PostCSS syntax in bundled css files.**

- `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.
