 # Changelog
 
+## 0.5.11
+
+New: Supports associative text editing.
+
+optimization: Optimizing theme configuration updates, changing configurations that do not involve node size does not trigger node recalculation.
+
+## 0.5.10
+
+New: Optimize node reuse logic using LRU caching algorithm.
+
+## 0.5.10-fix.1
+
+Fix: Fix the issue of import errors.
+
+## 0.5.10-fix.2
+
+Fix: Fixed the issue of switching themes and importing data without triggering data changes in rich text mode.
+
+New: Add three new themes.
+
+## 0.5.9
+
+Change: Unified export method format, using `FileReader` instead of `URL.createObjectURL` to convert `blob` data.
+
+## 0.5.8
+
+optimization: 1.The position setting is not triggered when the node position does not change. 2.The unfolding and folding status does not change and does not trigger button updates.
+
+New: 1.The default setting is to move the mouse over the node to display the expand and collapse buttons. 2.Support the list of icons that can be inserted into extended nodes.
+
+## 0.5.7
+
+Breaking change：In rich text mode, exporting png has been changed to using html2canvas to convert the entire svg, greatly improving the export speed. However, html2canvas has a bug where the text color inline with the dom node in the foreignObject element cannot be recognized. Therefore, the text color of the exported node is fixed. However, compared to the previously unavailable state of the export, it can at least be exported quickly and smoothly.
+
+optimization: Optimize the rich text node editing experience.
+
+New: In rich text mode, importing data, initializing data, and switching theme scene node styles support following theme changes.
+
+## 0.5.6
+
+Fix: 1.Fix the issue of node position disorder during fast and multiple renderings in a short period of time. 2.Fix the issue of dragging the canvas while the node is being edited, causing the edit box and node to separate.
+
+New: 1.Add a maximum history limit.
+
+## 0.5.5-fix.1
+
+Fix: 1.Fix the issue where the edit box is also outside the canvas when editing nodes outside the canvas. 2.After modifying the structure, reset the transformation to prevent the problem of sudden position changes during the first drag after switching the structure during scaling.
+
+optimization: 1.When multiple nodes are selected, as long as there is a cross between the node and the selection area, it is considered selected.
+
+## 0.5.5-fix.2
+
+Fix: 1.Fix mini map error.
+
+## 0.5.5
+
+New: 1.Supports configuring the padding when exporting to PNG, SVG, or PDF. 2.Support the configuration of z-index for node text editing boxes and node comment floating layer elements. 3.Support clicking on areas outside the canvas to end node editing status.
+
 ## 0.5.4
 
-New: 1.Add new themes.
+New: 1.Add new themes. 2.Added timeline and fishbone structure.
+
+Fix: 1.Fix the conflict issue between node right-click and canvas right-click. 2.Fix the bug that the line segment is not hidden when dragging nodes such as organizational chart and directory organization chart.
