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

This release inadvertently raised the minimum Node.js version from v20.0.0 to v20.19.0+, v22.12.0+, v24.0.0+. (This happened via a dependency update.) This probably should have been a breaking (major) change, instead of happening in a patch version, since it prevents using earlier Node.js versions.

After further testing, we found that most of our development dependencies also require these versions, and so it's not feasible for the jsdom project to support earlier Node.js versions. (For example, our testing frameworks will not run on them.) If you need to use such earlier versions, or otherwise are working in an environment which gives related errors such as ERR_REQUIRE_ESM, then please stick with the v26.1.0 release of jsdom. (Noting, of course, that such versions are unsupported, and we will not respond to bug reports opened against them.)

Subsequent jsdom releases will explicitly require these minimum Node.js versions, and will have CI testing to ensure that the minimum version is not accidentally raised again.

Normal changelog:

• 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)
