April was a big milestone for Servo, with some automated tests failing because they had hard\-coded cookie expiry dates set to April 2016 plus ten years\. Surprise\! We’re still here\. Here’s to the next 100 years of Servo \([@jdm](https://github.com/jdm),[\#44341](https://github.com/servo/servo/pull/44341)\)\. This is another big update, so here’s an outline: - [**Security**](https://servo.org/blog/2026/05/31/april-in-servo/#security) - [**Work in progress**](https://servo.org/blog/2026/05/31/april-in-servo/#work-in-progress) - [**servoshell**](https://servo.org/blog/2026/05/31/april-in-servo/#servoshell) - [**For developers**](https://servo.org/blog/2026/05/31/april-in-servo/#for-developers) - [**Embedding API**](https://servo.org/blog/2026/05/31/april-in-servo/#embedding-api) - [**More on the web platform**](https://servo.org/blog/2026/05/31/april-in-servo/#more-on-the-web-platform) - [**Performance and stability**](https://servo.org/blog/2026/05/31/april-in-servo/#performance-and-stability) ## Security[https://servo.org/blog/2026/05/31/april-in-servo/#security](https://servo.org/blog/2026/05/31/april-in-servo/#security) **Crypto­Key**now zeroes buffers containing key material after use \([@kkoyung](https://github.com/kkoyung),[\#44597](https://github.com/servo/servo/pull/44597)\)\. With only a few exceptions, you can only access DOM APIs in another document if that document is in the**same origin**\. But if that document is in the same*site*with a different port number, Servo currently allows these accesses even though it shouldn’t\. We’ve fixed some \(but not all\) of these incorrect accesses, specifically those that involve binding a Window or Location method in this document with a`this`from the other document \([@yvt](https://github.com/yvt),[@jdm](https://github.com/jdm),[\#28583](https://github.com/servo/servo/pull/28583)\)\. We’ve fixed a bug where**local­Storage**and**session­Storage**were usable in**sandboxed <iframe\>**and shared with every other sandboxed <iframe\>, rather than throwing Security­Error \([@Taym95](https://github.com/Taym95),[\#44002](https://github.com/servo/servo/pull/44002)\)\. We’ve fixed a bug where**local­Storage**and**session­Storage**were shared between all**<iframe srcdoc\> documents**, rather than isolated using the origin of the containing document \([@niyabits](https://github.com/niyabits),[\#43988](https://github.com/servo/servo/pull/43988),[\#44038](https://github.com/servo/servo/pull/44038)\)\. We’ve fixed a bug where**IndexedDB**was usable in**sandboxed <iframe\>**and**data: URL web workers**\([@Taym95](https://github.com/Taym95),[\#44088](https://github.com/servo/servo/pull/44088)\)\. We’ve fixed a bug where pages in some**IP address origins**can evict cookies from other IP address origins \([@officialasishkumar](https://github.com/officialasishkumar),[\#44152](https://github.com/servo/servo/pull/44152)\)\. Only evicting cookies was possible, not reading or writing them\. We’ve fixed an**out\-of\-bounds memory read**in**tex­Image3D\(\)**on**Web­GL2­Rendering­Context**\([@simartin](https://github.com/simartin),[\#44270](https://github.com/servo/servo/pull/44270)\), and fixed some undefined behaviour in servoshell’s signal handler \([@Narfinger](https://github.com/Narfinger),[\#43891](https://github.com/servo/servo/pull/43891)\)\. ## Work in progress[https://servo.org/blog/2026/05/31/april-in-servo/#work-in-progress](https://servo.org/blog/2026/05/31/april-in-servo/#work-in-progress) **IndexedDB**is now enabled in servoshell’s experimental mode \([@arihant2math](https://github.com/arihant2math),[\#44245](https://github.com/servo/servo/pull/44245)\)\. As always, embedders can enable it with[`Preferences`](https://doc.servo.org/servo/struct.Preferences.html)::[`dom­\_indexeddb­\_enabled`](https://doc.servo.org/servo/struct.Preferences.html#structfield.dom_indexeddb_enabled)\([@arihant2math](https://github.com/arihant2math),[\#44245](https://github.com/servo/servo/pull/44245),[\#44283](https://github.com/servo/servo/pull/44283)\)\. IndexedDB now uses Servo’s new**“client storage”**system, which is based on the[Storage Standard](https://storage.spec.whatwg.org/)and will allow us to have a unified on\-disk format and quota management for all web platform features that persistently store data \([@gterzian](https://github.com/gterzian),[\#44374](https://github.com/servo/servo/pull/44374),[\#43900](https://github.com/servo/servo/pull/43900)\)\. We’ve also made key range queries more efficient \([@arihant2math](https://github.com/arihant2math),[\#39009](https://github.com/servo/servo/pull/39009)\), landed improvements to IDB­Database, IDB­Object­Store, IDB­Cursor, IDB­Key­Range, IDB­Request, and to the handling of transactions, keys, values, and exceptions \([@Taym95](https://github.com/Taym95),[\#44128](https://github.com/servo/servo/pull/44128),[\#43901](https://github.com/servo/servo/pull/43901),[\#44009](https://github.com/servo/servo/pull/44009),[\#43914](https://github.com/servo/servo/pull/43914),[\#44161](https://github.com/servo/servo/pull/44161),[\#44183](https://github.com/servo/servo/pull/44183),[\#44059](https://github.com/servo/servo/pull/44059),[\#44215](https://github.com/servo/servo/pull/44215),[\#42998](https://github.com/servo/servo/pull/42998),[\#43805](https://github.com/servo/servo/pull/43805)\)\. We’ve made more progress on the**Intersection­Observer API**, under`\-\-pref dom­\_intersection­\_observer­\_enabled`\([@stevennovaryo](https://github.com/stevennovaryo),[@jdm](https://github.com/jdm),[\#42204](https://github.com/servo/servo/pull/42204)\)\. We’re continuing to implement**document\.exec­Command\(\)**for**rich text editing**\([@TimvdLippe](https://github.com/TimvdLippe),[\#44529](https://github.com/servo/servo/pull/44529)\), under`\-\-pref dom­\_exec­\_command­\_enabled`\. This release adds support for the**‘bold’**,**‘font­Name’**,**‘font­Size’**,**‘italic’**,**‘strikethrough’**, and**‘underline’**commands \([@TimvdLippe](https://github.com/TimvdLippe),[@jdm](https://github.com/jdm),[@mrobinson](https://github.com/mrobinson),[\#44511](https://github.com/servo/servo/pull/44511),[\#43287](https://github.com/servo/servo/pull/43287),[\#44432](https://github.com/servo/servo/pull/44432),[\#44410](https://github.com/servo/servo/pull/44410),[\#44194](https://github.com/servo/servo/pull/44194),[\#44030](https://github.com/servo/servo/pull/44030),[\#44039](https://github.com/servo/servo/pull/44039),[\#44041](https://github.com/servo/servo/pull/44041),[\#44075](https://github.com/servo/servo/pull/44075),[\#44234](https://github.com/servo/servo/pull/44234),[\#44250](https://github.com/servo/servo/pull/44250),[\#44331](https://github.com/servo/servo/pull/44331),[\#44390](https://github.com/servo/servo/pull/44390),[\#44137](https://github.com/servo/servo/pull/44137),[\#44293](https://github.com/servo/servo/pull/44293),[\#44312](https://github.com/servo/servo/pull/44312),[\#44347](https://github.com/servo/servo/pull/44347)\)\. All of the features above are enabled in servoshell’s experimental mode\. Servo can now build a very basic**accessibility tree**for web contents, under`\-\-pref accessibility­\_enabled`\([@alice](https://github.com/alice),[@delan](https://github.com/delan),[@lukewarlow](https://github.com/lukewarlow),[\#42338](https://github.com/servo/servo/pull/42338),[\#43558](https://github.com/servo/servo/pull/43558),[\#44437](https://github.com/servo/servo/pull/44437),[\#44438](https://github.com/servo/servo/pull/44438)\)\. This includes text runs, plus nine other non\-interactive accessibility roles \([@alice](https://github.com/alice),[@delan](https://github.com/delan),[\#44255](https://github.com/servo/servo/pull/44255)\)\. We’ve also fixed a crash when reloading pages with accessibility enabled \([@alice](https://github.com/alice),[\#44473](https://github.com/servo/servo/pull/44473)\), and made accessibility tree updates more efficient \([@alice](https://github.com/alice),[\#44208](https://github.com/servo/servo/pull/44208)\)\. We’ve started implementing the**Sanitizer API**, under`\-\-pref dom­\_sanitizer­\_enabled`\([@kkoyung](https://github.com/kkoyung),[\#44198](https://github.com/servo/servo/pull/44198),[\#44290](https://github.com/servo/servo/pull/44290),[\#44335](https://github.com/servo/servo/pull/44335),[\#44421](https://github.com/servo/servo/pull/44421),[\#44452](https://github.com/servo/servo/pull/44452),[\#44481](https://github.com/servo/servo/pull/44481),[\#44585](https://github.com/servo/servo/pull/44585),[\#44594](https://github.com/servo/servo/pull/44594)\)\. We’ve also started implementing**Shared­Worker**, under`\-\-pref dom­\_sharedworker­\_enabled`\([@Taym95](https://github.com/Taym95),[\#44375](https://github.com/servo/servo/pull/44375),[\#44440](https://github.com/servo/servo/pull/44440)\)\. We’re working on the**Wake­Lock API**too, under`\-\-pref dom­\_wakelock­\_enabled`\([@TG199](https://github.com/TG199),[@rovertrack](https://github.com/rovertrack),[\#43617](https://github.com/servo/servo/pull/43617),[\#44343](https://github.com/servo/servo/pull/44343)\)\. ## servoshell[https://servo.org/blog/2026/05/31/april-in-servo/#servoshell](https://servo.org/blog/2026/05/31/april-in-servo/#servoshell) servoshell for Android now has a**revamped browser UI**, including a new**history view**\([@espy](https://github.com/espy),[\#43795](https://github.com/servo/servo/pull/43795)\), the**apk is 30% smaller**\([@jschwe](https://github.com/jschwe),[\#44278](https://github.com/servo/servo/pull/44278),[\#44182](https://github.com/servo/servo/pull/44182)\), and we’ve fixed the black screen bug when closing settings or switching back from another app \([@yezhizhen](https://github.com/yezhizhen),[\#44327](https://github.com/servo/servo/pull/44327)\)\. You can now close tabs on OpenHarmony too \([@Narfinger](https://github.com/Narfinger),[\#42713](https://github.com/servo/servo/pull/42713)\)\. [](https://servo.org/img/blog/2026-05-android.png)As for servoshell on desktop platforms, we’ve fixed some focus\- and IME\-related bugs \([@mrobinson](https://github.com/mrobinson),[\#43872](https://github.com/servo/servo/pull/43872),[\#43932](https://github.com/servo/servo/pull/43932)\), and on Windows, we now install a normal shortcut without the strange behaviour of an “advertised” shortcut \([@yezhizhen](https://github.com/yezhizhen),[\#44223](https://github.com/servo/servo/pull/44223)\)\. ## For developers[https://servo.org/blog/2026/05/31/april-in-servo/#for-developers](https://servo.org/blog/2026/05/31/april-in-servo/#for-developers) When using the**Inspector**tab in the Firefox**DevTools**, the**Rules**panel now includes declarations in**‘@layer’ rules**\([@arabson99](https://github.com/arabson99),[\#43912](https://github.com/servo/servo/pull/43912)\)\. When**logging expressions**in the**Console**tab, and when**hovering over symbols**in the**Debugger**tab, you can now get more information about the contents of functions, arrays, objects, and other values \([@atbrakhi](https://github.com/atbrakhi),[@eerii](https://github.com/eerii),[\#44172](https://github.com/servo/servo/pull/44172),[\#44173](https://github.com/servo/servo/pull/44173),[\#44022](https://github.com/servo/servo/pull/44022),[\#44233](https://github.com/servo/servo/pull/44233),[\#44196](https://github.com/servo/servo/pull/44196),[\#44181](https://github.com/servo/servo/pull/44181),[\#44064](https://github.com/servo/servo/pull/44064),[\#44023](https://github.com/servo/servo/pull/44023),[\#44164](https://github.com/servo/servo/pull/44164),[\#44369](https://github.com/servo/servo/pull/44369),[\#44262](https://github.com/servo/servo/pull/44262)\)\. When using the**Debugger**tab, you can now use the**Scopes**panel to inspect local and global variables \([@eerii](https://github.com/eerii),[@atbrakhi](https://github.com/atbrakhi),[\#43792](https://github.com/servo/servo/pull/43792),[\#43791](https://github.com/servo/servo/pull/43791)\), you can now debug**web worker**scripts \([@atbrakhi](https://github.com/atbrakhi),[\#43981](https://github.com/servo/servo/pull/43981)\), and we’ve started implementing**blackboxing**, aka the**Ignore source**button \([@freyacodes](https://github.com/freyacodes),[\#44142](https://github.com/servo/servo/pull/44142)\)\. We’ve also landed some initial support for the**Style Editor**tab \([@rovertrack](https://github.com/rovertrack),[\#44517](https://github.com/servo/servo/pull/44517),[\#44462](https://github.com/servo/servo/pull/44462)\)\. We’re working towards re\-enabling our automated DevTools tests in CI, which should make the feature more reliable \([@freyacodes](https://github.com/freyacodes),[\#44577](https://github.com/servo/servo/pull/44577)\), and we’ve landed a small build reproducibility fix too \([@jschwe](https://github.com/jschwe),[\#44459](https://github.com/servo/servo/pull/44459)\)\. For developers of Servo itself, please note that the**Cargo ‘release’ profile**is no longer`\#\[cfg\(debug­\_assertions\)\]`\([@jschwe](https://github.com/jschwe),[@mrobinson](https://github.com/mrobinson),[\#44177](https://github.com/servo/servo/pull/44177)\)\. If you’ve been using ‘release’ as a “faster ‘debug’ with assertions” build locally, consider switching to ‘checked\-release’ or ‘medium’\. The pull request template has been updated \([@mrobinson](https://github.com/mrobinson),[\#44135](https://github.com/servo/servo/pull/44135)\)\.**‘Testing’**and**‘Fixes’**should go at the*bottom*of the PR description, and**‘Testing’**is about automated tests, not how you tested the PR locally\. We’ve made more progress on the new[**dev container**](https://containers.dev/), which will provide an alternative to[our usual procedures](https://book.servo.org/building/building.html)for setting up a Servo build environment \([@jschwe](https://github.com/jschwe),[@sagudev](https://github.com/sagudev),[\#44126](https://github.com/servo/servo/pull/44126),[\#44111](https://github.com/servo/servo/pull/44111),[\#44162](https://github.com/servo/servo/pull/44162),[\#44641](https://github.com/servo/servo/pull/44641),[\#44109](https://github.com/servo/servo/pull/44109)\)\. Keep an eye out for that[in the book](https://book.servo.org/building/building.html)\! In the meantime, did you know that you can use[**Lix**](https://lix.systems/)or[**Nix**](https://nixos.org/manual/nix/stable)to build Servo on Linux with a lot less hassle,*even if*you’re not using NixOS? For now at least, head to the[NixOS page](https://book.servo.org/building/nixos.html)in the book to learn more\. We’ve also fixed a regression that made`\-\-debug\-mozjs`and`MOZJS­\_FROM­\_SOURCE`builds take much longer to complete on Linux when not using Nix \([@jschwe](https://github.com/jschwe),[\#44346](https://github.com/servo/servo/pull/44346)\)\. We’ve fixed building Servo with the**‘jitspew’ feature**in mozjs, allowing you to set**IONFLAGS**to enable JIT logging \([@simonwuelker](https://github.com/simonwuelker),[\#44010](https://github.com/servo/servo/pull/44010)\)\. We’ve also fixed build issues on Windows and FreeBSD \([@zhangxichang](https://github.com/zhangxichang),[@mrobinson](https://github.com/mrobinson),[\#44264](https://github.com/servo/servo/pull/44264),[\#44591](https://github.com/servo/servo/pull/44591)\)\. ## Embedding API[https://servo.org/blog/2026/05/31/april-in-servo/#embedding-api](https://servo.org/blog/2026/05/31/april-in-servo/#embedding-api) With this second monthly release of the Servo library, we have some quick notes about**API stability**and**semver compatibility**: - **The[‘servo’](https://crates.io/crates/servo)package**follows[Cargo’s rules for semver compatibility](https://doc.rust-lang.org/1.88.0/cargo/reference/specifying-dependencies.html#default-requirements)\. 0\.1\.1 is compatible with version 0\.1\.0, but 0\.2\.0 is a breaking update\. - Until we integrate semver analysis into our release process, each monthly release will have a breaking version number, while non\-breaking version numbers may be used for LTS updates\. - In general,**dependencies of ‘servo’**, like[‘servo\-base’](https://crates.io/crates/servo-base)and[‘servo\-script’](https://crates.io/crates/servo-script),**do not use semver**\.

Servo makes its**first TLS connection**in each session**30–60 ms faster**\([@jschwe](https://github.com/jschwe),[\#44242](https://github.com/servo/servo/pull/44242)\), and we’ve instrumented the Servo and servoshell startup processes to find more opportunities for optimisation \([@jschwe](https://github.com/jschwe),[\#44443](https://github.com/servo/servo/pull/44443),[\#44456](https://github.com/servo/servo/pull/44456)\)\. Like most browser engines, Servo is a multi\-threaded \(and sometimes multi\-process\) system requiring a great deal of IPC messages to keep everything connected\.[Two key components](https://book.servo.org/design-documentation/architecture.html)of this system are the**constellation**thread, which manages the engine as a whole, and the**script threads**\(or web processes\), which render the web pages\. Sending these messages can be expensive though, so to**reduce unnecessary IPC traffic**, we’ve landed an optimisation that allows script threads to selectively receive only the relevant messages from the constellation \([@webbeef](https://github.com/webbeef),[\#43124](https://github.com/servo/servo/pull/43124)\)\. We’ve reduced the**memory usage**of each**Attr**,**Text**, and**Character­Data**node in the DOM by 16 bytes \([@mrobinson](https://github.com/mrobinson),[@Loirooriol](https://github.com/Loirooriol),[\#44074](https://github.com/servo/servo/pull/44074)\), and**fixed a memory leak**when deleting**<video controls\>**or**<audio controls\>**\([@Messi002](https://github.com/Messi002),[\#43983](https://github.com/servo/servo/pull/43983)\)\. Our**about:memory**page is more accurate now too, with new tracking of**libc memory allocations**on macOS, improved tracking of libc memory allocations on Linux \([@jschwe](https://github.com/jschwe),[\#44037](https://github.com/servo/servo/pull/44037)\), and more accurate tracking of Path­Buf and types in`tokio`,`http`,`data­\_url`, and`urlpattern`\([@Narfinger](https://github.com/Narfinger),[\#43858](https://github.com/servo/servo/pull/43858)\)\. Less memory usage isn’t always better in browser engines though, because there are many kinds of caches and other optimisations we can do to make browsing the web faster, at the expense of increased memory usage\. For example, we can greatly speed up**prototype checks**for DOM objects by storing a number in each object that identifies the concrete type, at the expense of making each DOM object 64 bits larger \([@webbeef](https://github.com/webbeef),[\#44364](https://github.com/servo/servo/pull/44364)\)\. Layout can now**reuse fragments**in later reflows, in many cases that involve block layout or ‘position: absolute’ \([@mrobinson](https://github.com/mrobinson),[@lukewarlow](https://github.com/lukewarlow),[@Loirooriol](https://github.com/Loirooriol),[\#42904](https://github.com/servo/servo/pull/42904),[\#44231](https://github.com/servo/servo/pull/44231)\)\.

But when DOM objects are being destroyed, those references can become invalid for a brief moment, depending on the order the GC finalizers run in\. This can be unsound if those references are accessed, which is a very easy mistake to make if the type has an`impl Drop`\. To help prevent that class of bug, we’re reworking our DOM types so that none of them have`\#\[dom­\_struct\]`and`impl Drop`at the same time \([@willypuzzle](https://github.com/willypuzzle),[\#44119](https://github.com/servo/servo/pull/44119),[\#44501](https://github.com/servo/servo/pull/44501),[\#44513](https://github.com/servo/servo/pull/44513)\)\. We’ve improved our static analysis for GC rooting \([@officialasishkumar](https://github.com/officialasishkumar),[\#44489](https://github.com/servo/servo/pull/44489)\), and we’ve continued our long\-running effort to**use the Rust type system**to make certain kinds of dynamic borrow failures impossible \([@sagudev](https://github.com/sagudev),[@TimvdLippe](https://github.com/TimvdLippe),[@Narfinger](https://github.com/Narfinger),[@elomscansio](https://github.com/elomscansio),[@Gae24](https://github.com/Gae24),[@rovertrack](https://github.com/rovertrack),[@yezhizhen](https://github.com/yezhizhen),[@nodelpit](https://github.com/nodelpit),[\#43174](https://github.com/servo/servo/pull/43174),[\#43524](https://github.com/servo/servo/pull/43524),[\#43928](https://github.com/servo/servo/pull/43928),[\#43943](https://github.com/servo/servo/pull/43943),[\#43942](https://github.com/servo/servo/pull/43942),[\#43944](https://github.com/servo/servo/pull/43944),[\#43946](https://github.com/servo/servo/pull/43946),[\#43952](https://github.com/servo/servo/pull/43952),[\#43975](https://github.com/servo/servo/pull/43975),[\#44018](https://github.com/servo/servo/pull/44018),[\#44175](https://github.com/servo/servo/pull/44175),[\#44241](https://github.com/servo/servo/pull/44241),[\#44368](https://github.com/servo/servo/pull/44368),[\#44406](https://github.com/servo/servo/pull/44406),[\#44441](https://github.com/servo/servo/pull/44441),[\#44422](https://github.com/servo/servo/pull/44422),[\#44475](https://github.com/servo/servo/pull/44475),[\#44478](https://github.com/servo/servo/pull/44478),[\#44484](https://github.com/servo/servo/pull/44484),[\#44476](https://github.com/servo/servo/pull/44476),[\#44490](https://github.com/servo/servo/pull/44490),[\#44477](https://github.com/servo/servo/pull/44477),[\#44494](https://github.com/servo/servo/pull/44494),[\#44497](https://github.com/servo/servo/pull/44497),[\#44498](https://github.com/servo/servo/pull/44498),[\#44495](https://github.com/servo/servo/pull/44495),[\#44505](https://github.com/servo/servo/pull/44505),[\#44506](https://github.com/servo/servo/pull/44506),[\#44507](https://github.com/servo/servo/pull/44507),[\#44508](https://github.com/servo/servo/pull/44508),[\#44509](https://github.com/servo/servo/pull/44509),[\#44510](https://github.com/servo/servo/pull/44510),[\#44512](https://github.com/servo/servo/pull/44512),[\#44482](https://github.com/servo/servo/pull/44482),[\#44527](https://github.com/servo/servo/pull/44527),[\#44528](https://github.com/servo/servo/pull/44528),[\#44531](https://github.com/servo/servo/pull/44531),[\#44534](https://github.com/servo/servo/pull/44534),[\#44542](https://github.com/servo/servo/pull/44542),[\#44533](https://github.com/servo/servo/pull/44533),[\#44543](https://github.com/servo/servo/pull/44543),[\#44553](https://github.com/servo/servo/pull/44553),[\#44547](https://github.com/servo/servo/pull/44547),[\#44563](https://github.com/servo/servo/pull/44563),[\#44562](https://github.com/servo/servo/pull/44562),[\#44565](https://github.com/servo/servo/pull/44565),[\#44558](https://github.com/servo/servo/pull/44558),[\#44583](https://github.com/servo/servo/pull/44583),[\#44606](https://github.com/servo/servo/pull/44606),[\#44605](https://github.com/servo/servo/pull/44605),[\#44608](https://github.com/servo/servo/pull/44608),[\#44602](https://github.com/servo/servo/pull/44602),[\#44584](https://github.com/servo/servo/pull/44584),[\#44620](https://github.com/servo/servo/pull/44620),[\#44590](https://github.com/servo/servo/pull/44590),[\#44254](https://github.com/servo/servo/pull/44254),[\#44628](https://github.com/servo/servo/pull/44628),[\#44629](https://github.com/servo/servo/pull/44629),[\#44638](https://github.com/servo/servo/pull/44638),[\#44626](https://github.com/servo/servo/pull/44626),[\#44081](https://github.com/servo/servo/pull/44081)\)\.
