The markdown parsing is broken/disabled for release notes. Sorry about that, I'm chasing the source of a crash that's been bringing this website down for the last couple of days.
# Version 11.4.1
## iOS:
1. Fixed Privacy Manifest File, #434
## Framework bug fixes:
1. Fixed #20784, a regression in v11.4.0 causing wrong min and max extremes for the selection event in column charts.
2. Fixed #20710, bubble legend with color-axis moved after redraw.
3. Fixed #20792, plot lines' HTML labels rendered incorrectly.
4. Fixed #18980, the `highcharts.d.ts` type definition file was too large and caused issues in editors. Moved majority of series options into separate definition files.
5. Fixed #20871, a regression with resetting zoom across synchronized charts.
6. Fixed #20586, plot line CSS classes were not concatenated with spaces, causing the `className` option to fail.
7. Fixed #20548, chart not resizing after closing fullscreen.
# Version 11.4.0
## iOS:
1. Removed `.woff2` fonts from the framework, #432
2. Added a privacy manifest file to the framework, #433
## Framework:
1. Added new option `sankey.nodeDistance` and the possibility of setting `sankey.nodeWidth` to `auto`. The same option pair is also supported by organization chart and treegraph series.
2. Enhanced the pinch zoom behavior to redraw the axes and series continuously. Previously it created a preview by scaling the graphs, then did a full review at the end. Also a deeper refactor and unification of the whole zoom, pan and mousewheel logic.
3. Added new option `organization.hangingSide` which allows nodes to hang from the right side in inverted organization charts. See #17240.
## Framework bug fixes:
1. Fixed #20334, chart width exceeded container width on Windows when the chart itself caused page scrollbars.
2. Fixed #20572, destroying a chart after point hover sometimes produced an error.
3. Fixed #15921 by applying `fillColor` to series from `highContrastTheme.colors` if set.
4. Fixed #20166, ticks and gridlines were visible outside the axis in some corner cases.
5. Fixed code scan issues 56, incomplete string escaping or encoding in SVGRenderer, and 72, incomplete multi-character sanitization in SVGRenderer.
6. Fixed code scan issue 73, incomplete multi-character sanitization in SVGElement node title.
7. Fixed code scan issue 90, permissive regex in `mapcharts.js`.
8. Fixed code scan issue 111, potential prototype pollution in `Utilities.ts`.
9. Fixed code scan issue 112, potential prototype pollution in `NavigationBinding.ts`.
10. Fixed #20329, detached elements and events in the Accessibility module produced a memory leak.
11. Fixed #20394, `series.color` only initially impacted the color of x-range points.
12. Fixed #20435, point events update didn't work.
13. Fixed #20516, `this` was not bound to plot line or plot band object in event callbacks.
14. Fixed #20429, toggling bellcurve visibility threw error.
15. Fixed #20440 and #20569, multiple series zones broke graph.
16. Fixed regression since v11.3, column range series had area-style legend marker.
17. Fixed #20433, boosted scatter chart did not work without axis min/max-options.
18. Fixed #20307 and #20301, alignment and overlap detection for rotated data labels didn't work correctly.
19. Fixed #19730, centerInCategory on inverted column chart had incorrect series order.
20. Fixed #20264, the packed bubble series was not rendered correctly in an inverted chart.
# Version 11.3.0
## iOS:
1. Added methods for updating the chart options with JSON to `HIChartView`, #429
## Framework:
1. Implemented native handling of the `time.timezone` option, making the dependency on moment.js redundant.
2. Added new options `colorAxis.width` and `colorAxis.height`, allowing absolute or relative size. See #17870.
3. Added new option `chart.axisLayoutRuns`. It allows opting in for more predictable axis tick and label layout, at the cost of performance. See #19794.
4. Added new default `legendSymbol` for area series and its derivatives.
## Framework upgrade notes:
1. The `exporting.formAttributes` no longer works because the internal `post` function was replaced by the `fetch` API. The `formAttributes` option can for some purposes be replaced with `exporting.fetchOptions`. See `the fetch article on MDN` for more information about possible options.
## Framework bug fixes:
1. Fixed #19169, the `focusBorder` was not removed from `SVGElement` after the element had been unfocused.

2. Added the heatmap.interpolation option for creating smooth heatmaps.
3. Added new function, Chart.getOptions(), to get the current active configuration options for the chart.
4. Added the treegraph.fillSpace option for treegraphs to fill the whole plot area even when some points are collaped.
5. Added `borderRadius` option support for funnel and pyramid series. See #18839.
6. Added new option, xAxis.crossing and yAxis.crossing, making it easier to create axis layout for mathematical plots.
7. Added new option, series.legendSymbol. See #18753.
8. Design facelift with clearer, more vivid palette, added contrast for text labels and many minor visual changes.
9. Added new series type, treegraph. Read more in the docs.

11. Removed support for IE 8 and older.
12. Changed the default builds to ECMAScript version ES2016.
13. Replaced SASS files for styledMode with updated CSS files. Highcharts theming is now easier by supporting CSS variables as well as `prefers-color-scheme`. See style by CSS.

15. Changed default rotationMode to `circular` for sunburst data labels.
16. Added minorTicksPerMajor option for axes, see #13338.

## Framework upgrade notes:
1. To revert to the old design, use the theme defined in the v10 theme sample.
2. Font sizes of the chart are now using rem by default. This may cause too small or too big fonts if your web page is using non-default root element font size. To avoid that, set chart.style.fontSize to 16px or any other values you see fit.
3. The top-level labels option has been deprecated for a long time and is now removed. Use Annotations instead.
4. Time-related settings on the global options structure are removed. Use the time options instead.

6. The default builds were changed to ECMAScript version ES2016. See the system requirements on how to support IE11 and other legacy browsers.
7. If you're using chart.styledMode, and your end users have prefers-color-scheme set to dark in their browsers, they may now be presented with dark-themed charts. The exception is if your CSS overrides the default coloring.
8. Changed default rotationMode to circular for sunburst data labels.
