August in Servo: CSS Grid, text selection, and more

# August in Servo: CSS Grid, text selection, and more! - Servo aims to empower developers with a lightweight, high-performance alternative for embedding web technologies in applications. Source: [https://servo.org/blog/2026/10/09/august-in-servo/](https://servo.org/blog/2026/10/09/august-in-servo/) [**Servo 0\.6\.0**](https://github.com/servo/servo/releases/tag/v0.6.0)contains all of the changes we landed in August, which came out to**417 commits**\! The big news is that we’ve turned on support for**CSS Grid**by default \([@nicoburns](https://github.com/nicoburns),[\#45621](https://github.com/servo/servo/pull/45621)\)\. This has had a huge positive impact on the visual appearance of many websites\!

Who knew that loading`about:blank`was[so complicated](https://hsivonen.fi/about-blank/)? The upshot to all this work is that pages that open additional windows or include iframes work much more reliably\. This is another big update, so here’s an outline: - [**Security**](https://servo.org/blog/2026/10/09/august-in-servo/#security) - [**Real world compat**](https://servo.org/blog/2026/10/09/august-in-servo/#real-world-compat) - [**Work in progress**](https://servo.org/blog/2026/10/09/august-in-servo/#work-in-progress) - [**Embedding API**](https://servo.org/blog/2026/10/09/august-in-servo/#embedding-api) - [**For users and developers**](https://servo.org/blog/2026/10/09/august-in-servo/#for-users-and-developers) - [**More on the web platform**](https://servo.org/blog/2026/10/09/august-in-servo/#more-on-the-web-platform) - [**Performance and stability**](https://servo.org/blog/2026/10/09/august-in-servo/#performance-and-stability) - [**New contributors**](https://servo.org/blog/2026/10/09/august-in-servo/#new-contributors) ## Security[https://servo.org/blog/2026/10/09/august-in-servo/#security](https://servo.org/blog/2026/10/09/august-in-servo/#security) We upgraded to**SpiderMonkey v153**, which brings many new security and crash fixes to Servo’s JavaScript engine integration \([@sagudev](https://github.com/sagudev),[@Gae24](https://github.com/Gae24),[\#47489](https://github.com/servo/servo/pull/47489)\)\.

See Niya’s[blog post](https://text.tchncs.de/niya/wrapping-up-my-work-on-servos-audioworklet)about her Outreachy project for more details\! We’re continuing work on the**ServiceWorker**feature, which can be enabled with`\-\-pref dom\_serviceworker\_enabled`\. This month we implemented the**CookieStore**interface behind the`\-\-pref dom\_cookiestore\_enabled`command line argument \([@Taym95](https://github.com/Taym95),[\#47044](https://github.com/servo/servo/pull/47044)\) as well as the**Cache**interface \([@gterzian](https://github.com/gterzian),[\#47220](https://github.com/servo/servo/pull/47220)\)\. Servo now supports a**disk\-backed HTTP cache**that can be enabled with`\-\-pref network\_http\_disk\_cache`\([@Narfinger](https://github.com/Narfinger),[\#43819](https://github.com/servo/servo/pull/43819)\)\. This cache persists between runs, but there is not yet any way to clear it\. ## Embedding API[https://servo.org/blog/2026/10/09/august-in-servo/#embedding-api](https://servo.org/blog/2026/10/09/august-in-servo/#embedding-api) **Breaking change:**[`WebView`](https://doc.servo.org/servo/struct.WebView.html)::`toggle\_sampling\_profiler`has been removed \([@lumiscosity](https://github.com/lumiscosity),[\#47014](https://github.com/servo/servo/pull/47014)\)\. To perform sampling profiling on Servo, follow the instructions in[the book](https://book.servo.org/contributing/profiling.html)\. **Breaking change:**The variants of[`MouseButton`](https://doc.servo.org/servo/enum.MouseButton.html)have been renamed to`Primary`,`Secondary`, and`Auxiliary`\([@mrobinson](https://github.com/mrobinson),[@SimonSapin](https://github.com/SimonSapin),[\#47327](https://github.com/servo/servo/pull/47327)\)\. We’ve added several new Cargo features reflecting common usage patterns: - `default\_web\_features`, to include optional web platform features in the build \(e\.g\. WebXR and WebGPU\) \([@jschwe](https://github.com/jschwe),[\#44032](https://github.com/servo/servo/pull/44032)\) - `bundled`, to include required resources in the binary \([@jschwe](https://github.com/jschwe),[\#44032](https://github.com/servo/servo/pull/44032)\) - `brotli\-compression\-stream`, enabling support for`brotli`content in the`CompressionStream`/`DecompressionStream`web APIs \([@Narfinger](https://github.com/Narfinger),[@jdm](https://github.com/jdm),[\#47197](https://github.com/servo/servo/pull/47197)\) - `webcrypto`, to enable support for the Crypto and WebCrypto web APIs \([@Narfinger](https://github.com/Narfinger),[\#47198](https://github.com/servo/servo/pull/47198)\) - `webgl`, to enable support for WebGL \([@janeoa](https://github.com/janeoa),[\#47200](https://github.com/servo/servo/pull/47200)\) ## For users and developers[https://servo.org/blog/2026/10/09/august-in-servo/#for-users-and-developers](https://servo.org/blog/2026/10/09/august-in-servo/#for-users-and-developers) One visible change is that interactive**text selection**now works\! This is the result of lots of work across our script and layout code to ensure it respects the actual geometry of the page content \([@mrobinson](https://github.com/mrobinson),[@SimonSapin](https://github.com/SimonSapin),[\#47022](https://github.com/servo/servo/pull/47022),[\#47025](https://github.com/servo/servo/pull/47025),[\#47329](https://github.com/servo/servo/pull/47329),[\#47358](https://github.com/servo/servo/pull/47358),[\#46982](https://github.com/servo/servo/pull/46982),[\#47425](https://github.com/servo/servo/pull/47425),[\#47438](https://github.com/servo/servo/pull/47438),[\#47437](https://github.com/servo/servo/pull/47437),[\#47581](https://github.com/servo/servo/pull/47581),[\#47070](https://github.com/servo/servo/pull/47070),[\#47048](https://github.com/servo/servo/pull/47048),[\#46963](https://github.com/servo/servo/pull/46963)\)\.

Historically,**about:memory**has reported all memory usage by Rust implementations of JS APIs as one undifferentiated`js/malloc\-heap`number\. We now break it down by memory usage of nodes in document trees \([@pylbrecht](https://github.com/pylbrecht),[\#46931](https://github.com/servo/servo/pull/46931)\) and interfaces that are not part of the DOM \([@jdm](https://github.com/jdm),[\#47531](https://github.com/servo/servo/pull/47531)\)\. We also report memory usage for the network stack’s cookie database \([@Narfinger](https://github.com/Narfinger),[\#47248](https://github.com/servo/servo/pull/47248)\) and the canvas renderer backend \([@janeoa](https://github.com/janeoa),[@jdm](https://github.com/jdm),[\#46958](https://github.com/servo/servo/pull/46958)\)\. We’ve added an**experimental threadboost**mechanism \([@jschwe](https://github.com/jschwe),[@mrobinson](https://github.com/mrobinson),[\#46843](https://github.com/servo/servo/pull/46843),[\#47027](https://github.com/servo/servo/pull/47027)\) that has been observed to improve Speedometer results by**50%**and allow canvas rendering to reach 60 FPS\. This is initially enabled for OpenHarmony, but future expansion to other Linux\-based platforms is expected\. ## More on the web platform[https://servo.org/blog/2026/10/09/august-in-servo/#more-on-the-web-platform](https://servo.org/blog/2026/10/09/august-in-servo/#more-on-the-web-platform) We upgraded to[resvg 0\.48](https://github.com/linebender/resvg/blob/main/CHANGELOG.md#0480-2026-07-31), fixing**many issues with SVG images**with missing width/height attributes that specified a`viewBox`\([@nicoburns](https://github.com/nicoburns),[\#46937](https://github.com/servo/servo/pull/46937)\)\. Upgrading to[Taffy 0\.14](https://github.com/DioxusLabs/taffy/blob/main/CHANGELOG.md#0130)fixed a number of**CSS grid\-related crashes**, support for grid names, better intrinsic sizing, and improved performance \([@nicoburns](https://github.com/nicoburns),[\#47031](https://github.com/servo/servo/pull/47031),[\#47493](https://github.com/servo/servo/pull/47493)\)\. We also fixed some issues in the Taffy grid integration for more accurate baselines \([@nicoburns](https://github.com/nicoburns),[\#47518](https://github.com/servo/servo/pull/47518)\)\. Session history traversals \(i\.e\. navigating backwards or forwards in history\) now wait for any outstanding traversal to complete \([@mrobinson](https://github.com/mrobinson),[\#47293](https://github.com/servo/servo/pull/47293),[\#47485](https://github.com/servo/servo/pull/47485)\)\. Meanwhile, navigations to`about:blank`are skipped if the initial about:blank document is present \([@jdm](https://github.com/jdm),[\#47074](https://github.com/servo/servo/pull/47074)\)\. `about:blank`documents no longer use the asynchronous HTML parser \([@jdm](https://github.com/jdm),[\#47050](https://github.com/servo/servo/pull/47050)\), and no longer report a`readyState`of`LOADING`\([@mrobinson](https://github.com/mrobinson),[\#47450](https://github.com/servo/servo/pull/47450)\)\.

For non\-about:blank content, we also made the document loading phases more reliable \([@TimvdLippe](https://github.com/TimvdLippe),[@mrobinson](https://github.com/mrobinson),[\#47426](https://github.com/servo/servo/pull/47426)\), improved conformance of`javascript:`URL evaluation and navigation target selection \([@mrobinson](https://github.com/mrobinson),[\#47486](https://github.com/servo/servo/pull/47486),[\#47516](https://github.com/servo/servo/pull/47516)\), and addressed longstanding compatibility issues with cross\-origin`Window`and`Location`objects \([@mrobinson](https://github.com/mrobinson),[\#47549](https://github.com/servo/servo/pull/47549)\)\. Our media playback has improved; we fixed several issues around**canPlayType\(\)**on**HTMLMediaElement**that allow Servo to report that**MP4 content is playable**\([@jdm](https://github.com/jdm),[\#47612](https://github.com/servo/servo/pull/47612),[\#47641](https://github.com/servo/servo/pull/47641),[\#47670](https://github.com/servo/servo/pull/47670)\)\.
