Release Notes

jsdom/jsdom (jsdom)

v27.4.0

Compare Source

• Added TextEncoder and TextDecoder.
• Improved decoding of HTML bytes by using the new @exodus/bytes package; it is now much more correct. (ChALkeR)
• Improved decoding of XML bytes to use UTF-8 more often, instead of sniffing for <meta charset> or using the parent frame's encoding.
• Fixed a memory leak when Ranges were used and then the elements referred to by those ranges were removed.

v27.3.0

Compare Source

• Improved CSS parsing and CSSOM object APIs via updates to @acemir/cssom. (acemir)

v27.2.0

Compare Source

• Added CSSGroupingRule, CSSNestedDeclarations, CSSConditionRule, CSSContainerRule, CSSScopeRule, CSSSupportsRule, CSSLayerBlockRule, and CSSLayerStatementRule to jsdom Windows. (acemir)
• Improved CSS parsing and CSSOM object APIs via updates to @acemir/cssom. (acemir)
• Fixed @import-ed stylesheets to be properly exposed to CSSOM, and not to overwrite the sheet created from the <link> or <style> element. (acemir)

v27.1.0

Compare Source

• Improved CSS parsing by switching to @acemir/cssom, including support for nested selectors, nested declarations, layer statements, and improved at-rule validation. (acemir)
• Fixed some selector cache invalidation issues where changes to attributes were not being picked up. (asamuzaK)
• Fixed package.json "engines" field to reflect the new minimum Node.js versions needed to run jsdom, as noted in the changelog for v27.0.1.

v27.0.1

Compare Source

• Fixed some regressions in CSS selectors. Most such regression fixes were done in a minor update of a dependency, and thus available for all fresh installs of v27.0.0. However, one related to class="" attribute changes is only possible with a new version of jsdom. (asamuzaK)
