 ### Prevent single pixel gaps between elements
 
 This release addresses the issue of 1px gaps appearing between fractionally sized elements when placed border-to-border. This was particularly pronounced in DPI-scaled layouts, as that often leads to fractionally sized elements.
 
-The solution involves rounding the rendered sizes of elements based on their absolute positions to ensure that the bottom/right of one element matches the top/left of the next element. This implies that the rendered size of a fractional element may vary by up to one pixel. This generally matches how web browsers behave. Floating-point precision issues may still cause rare gaps, but the improvements should cover almost all cases. See the [commit message](https://github.com/mikke89/RmlUi/commit/b197f985b328d5493af3190e27d4290bb496ff1d) for details. Resolves #438, thanks to @mwl4 for the extensive initiative and proof of concept.

 - The handle now retains the anchoring that applies to the target element, even after moving or sizing it. #637
   - If an element has all of its inset (top/right/bottom/left) properties set, this determines the size, and anchors to all edges. Previously, we would break the anchoring and just declare its new position or size. Now, positioning and sizing is performed in a way that retains this anchoring. Similarly, this applies to every combination of anchoring.
-  - Thus, when first sizing and moving the target, and then resizing its container, the element can now still resize itself to match the new dimensions.

 - The `edge_margin` attribute is introduced to constrain the target placement to the edges of its containing block. #631 
   - Applies to both position and size targets.
   - This attribute can take any length or percentage, which specifies the minimum distance between the target and the edges of its containing block. Each side can be specified individually, and negative values are allowed. See the [documentation](https://mikke89.github.io/RmlUiDoc/pages/rml/controls.html#handle) for details.
