Covers the performance hint suite, built-in CSS and HTML minification, the native CSS story, the nodeModules externals preset, the glob rule condition and the rest of the release. The benchmark table comparing the native pipeline with the loader one is a placeholder pending real measurements, and the banner image still has to be added.

webpack/codemods ships @webpack/css-plugins-to-native-css, which does the mini-css-extract-plugin and style-loader/css-loader migration the post describes by hand. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

The Benchmarks section keeps its placeholder note until the real measurements are in. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Drops the empty Benchmarks section and its table of contents entry, and says instead where the win comes from: the built-in support parses each stylesheet once as CSS instead of once per loader plus once as a JavaScript module, so a build whose work is mostly CSS gains the most.

A module or modern-module library, and any library under futureDefaults, no longer gets the default eval source map in development, since the eval wrapper hides import.meta from the bundler reading the library. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Builds the banner in the style of the 5.108 and 5.109 ones: the webpack lockup from src/assets/logo-on-dark-bg.svg, Geomanist for the type, and the same palette, sizes and layout measured off webpack-5-109.png. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

The Codemod CLI takes the package directly; 'run' is not part of it. Matches the command the Native CSS guide already documents, which the post now links to for the full option mapping. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

Release post for webpack 5.110.0. Stacked on top of #8337 (
docs/webpack-5-110), so merge that one first and review only the last commit here; the base will be retargeted tomainonce #8337 lands.What the post covers
hints: "stats"for adopting them without turning a build red.optimization.minimizeobject.css-loader,style-loaderandmini-css-extract-pluginare deprecated in favour ofexperiments.css, with a migration diff and the four caveats that actually bite (module vs global by extension, class name generation moving to the generator options, preprocessors staying as loaders, extracted CSS being a real chunk asset).nodeModulesexternals preset, theglobrule condition, tree shaking and scope hoisting work, SSR styles, HTML, output and library options, MultiCompiler, and the usual bug fix and performance section.Blocked on two things before this can be published
### Benchmarkssection is an empty table with a visible placeholder line. It needs real measurements of the same app built both ways (css-loader+mini-css-extract-pluginagainstexperiments.css): cold production build, rebuild with a warm cache, HMR update time, peak memory and emitted CSS bytes.src/assets/blog/webpack-5-110.pngdoes not exist yet, so the post has no banner import. It has to be added back the way the previous posts do it.The date in the filename and the
sortfield are a placeholder too, and should be moved to the actual release date.Notes
prettier,eslintandmarkdownlintpass. The 26 internal links were checked to resolve to a real file and anchor, as were the in-page table of contents anchors.
