• Commit log (from last canary): https://github.com/11ty/eleventy/compare/v4.0.0-alpha.5...v4.0.0-alpha.6

Bug Fixes

• Breaking (very low-risk): Fixes #2766. Changes how boolean attributes are rendered in the HTML Base plugin (and other plugins using the HTML Transformer API). e.g. <input disabled> now outputs as <input disabled> instead of <input disabled="">
• Fixes #4188 bug with setLiquidOptions addding global data by @paulrobertlloyd in https://github.com/11ty/eleventy/pull/4189
• Fixes #4187 canary bug with CDATA wrapper on Markdown files
• Fixes #4191 error with Eleventy layout resolution without file extensions (when key conflicted with a directory name in the includes or layouts folders)
• Fixes #1645 issue with JavaScript 11ty.js templates that assign data or render callbacks using Public class fields
• Fixes #3536 using content in data cascade with eleventyConfig.setFreezeReservedData(false) should not supersede content when rendering upstream Eleventy Layouts.

Dependency Updates

• Breaking (medium risk): Swap to use the dependency-updated pre-release of the 11ty fork of Nunjucks, see @11ty/nunjucks. If you’re relying on the nunjucks package in your project (and did a bad by not installing it into your dependencies), you can swap that code to use @11ty/nunjucks (or less desirably npm install nunjucks into your project’s dependencies).
• Breaking (low-risk): Upgrades to @11ty/recursive-copy@5 from @4 #4192. Affects glob parsing in passthrough copy via minimatch dependency upgrade, if you see issues please look at the relevant changelog
• Swap from please-upgrade-node to @11ty/node-version-check
• Upgrade to @11ty/eleventy-dev-server@3.0.0-alpha.6
