Going forward​

This is our third year running our quiet period experiment, and we've had a lot of success so far in balancing a month of rest with maintaining our normal release cadence afterwards. Therefore, we've decided to make this a regular part of our release calendar going forward. We'll still be putting a reminder into the last stable release of every calendar year.

See you all in 2024!

Der erste Commit in das electron/electron Repository war am 13. März 2013¹.

10 Jahre und 27.147 weitere Commits von 1192 individuellen Mitwirkenden später, Electron ist heute zu einem der beliebtesten Frameworks für das Erstellen von Desktop-Anwendungen geworden. Dieser Meilenstein ist die perfekte Gelegenheit, um unsere bisherige Reise zu feiern und zu reflektieren, und mitzuteilen, was wir auf dem Weg gelernt haben.

Wir wären heute nicht hier ohne alle, die ihre Zeit und Mühe geopfert haben, um das Projekt zu unterstützen. Obwohl Quellcode-Commits immer die sichtbarsten Beiträge sind, müssen wir auch die Anstrengungen der Leute anerkennen, die Fehler melden, userland-Module warten, Dokumentation und Übersetzungen bereitstellen und an der Electron Community im gesamten Cyberspace teilnehmen. Jeder Beitrag ist für uns als Betreiber von unschätzbarem Wert.

Bevor wir mit dem Rest des Blog-Beitrags fortfahren: Vielen Dank. ❤️

Wie sind wir zu diesem Punkt gekommen?​

Atom Shell wurde als Gerüst für GitHubs Atom-Editorgebaut, der im April 2014 in die öffentliche Beta startete. Es wurde von Grund auf als Alternative zu den webbasierten Desktop-Frameworks gebaut, die zu dieser Zeit verfügbar waren (node-webkit und Chromium Embedded Framework). Es hatte eine Killer-Funktion: Einbetten von Node.js und Chromium, um eine leistungsfähige Desktop-Laufzeit für Web- Technologien zu bieten.

Innerhalb eines Jahres begann Atom Shell ein immenses Wachstum der Fähigkeiten und Popularität zu sehen. Große Firmen, Startups und einzelne Entwickler hatten gleichermaßen damit begonnen, Apps damit zu bauen (einige frühe Anwender waren Slack, GitKraken, und WebTorrent), und das Projekt wurde treffend in Electron umbenannt.

Von da an startete Electron voll durch und hielt nie auf. Hier ist ein Blick auf unsere wöchentliche Download-Anzahl über die Zeit, dank npmtrends.com:

Electron v1 wurde 2016 veröffentlicht und versprach eine höhere API-Stabilität und bessere Dokumentation und Werkzeuge. Electron v2 wurde 2018 veröffentlicht und führte semantische Versionierung ein, was es den Entwicklern von Electron einfacher macht, den Release-Zyklus zu verfolgen.

Mit Electron v6 haben wir auf eine reguläre 12-wöchige große Release-Kadenz umgeschaltet, um der Chromium-Kadenz zu folgen. Diese Entscheidung war ein Mentalitätswandel für das Projekt und hat "die aktuellste Chromium-Version zu haben" von einem Nice-to-have zu einer Priorität gemacht. Dies hat die Menge an technischer Schulden zwischen den Upgrades reduziert und macht es uns einfacher, Electron aktualisiert und sicher zu halten.

Seitdem sind wir eine gut geölte Maschine und veröffentlichen eine neue Elektro-Version am selben Tag wie jede stabile Version von Chromium. Als Chromium 2021 seinen Veröffentlichungszyklus auf 4 Wochen beschleunigte, konnten wir entspannt darauf reagieren und unseren Veröffentlichungsrhythmus entsprechend auf 8 Wochen erhöhen.

Wir sind nun bei Electron v23 (und es geht weiter) und sind weiterhin bestrebt, die beste Laufzeitumgebung für die Erstellung plattformübergreifender Desktop-Anwendungen zu entwickeln. Trotz des Booms von JavaScript-Entwicklerwerkzeugen in den letzten Jahren ist Electron ein stabiler und erprobter Eckpfeiler im Bereich der Desktop-Anwendungs-Frameworks geblieben. Heutzutage sind Electron-Apps allgegenwärtig: Du kannst mit Visual Studio Code programmieren, mit Figma designen, mit Slack kommunizieren und mit Notion Notizen machen (unter vielen anderen Anwendungsfällen). Wir sind unglaublich stolz auf diese Leistung und dankbar für alle, die dies möglich gemacht haben.

Was haben wir auf dem Weg gelernt?​

Der Weg zur Dekaden-Marke war lang und gewunden. Hier sind ein Paar der Kernelemente, die uns geholfen haben, ein solch großes Open-Source Projekt am Leben zu erhalten.

Skalierung verteilter Entscheidungsfindung mit einem Governance-Modell​

Eine Herausforderung, die wir bewältigen mussten, war, die langfristige Richtung des Projekts zu bewältigen, nachdem Electron zum ersten Mal in der Popularität explodierte. Wie gehen wir damit um, ein Team von ein paar Dutzend Ingenieuren zu sein, die über Firmen, Länder und Zeitzonen verteilt arbeiten?

In den Anfangstagen verließ sich die Gruppe der Electron-Maintainer auf informelle Koordination, die für kleinere Projekte schnell und unkompliziert ist, aber nicht auf breitere Zusammenarbeit skaliert. 2019 wechselten wir zu einem Governance-Modell, bei dem verschiedene Arbeitsgruppen formelle Verantwortungsbereiche haben. Dies war entscheidend, um Prozesse zu optimieren und Projektanteile spezifischen Maintainers zuzuweisen. Wofür ist jede Arbeitsgruppe (WG) heutzutage verantwortlich?

• Electron-Versionen herausbringen (Releases WG)
• Upgrade von Chromium und Node.js (Upgrades WG)
• Überwachung des öffentlichen API-Designs (API WG)
• Electron sicher halten (Sicherheit WG)
• Die Webseite am Laufen halten, Dokumentation und Bereitstellung von Werkzeugen (Ecosystem WG)
• Community und Firmenreichweite (Outreach WG)
• Community-Moderation (Community & Safety WG)
• Wartung unserer Build-Infrastruktur, Maintainer-Tools und Cloud-Services (Infrastructure WG)

Etwa zur gleichen Zeit, als wir zum Governance-Modell wechselten, übertrugen wir auch das Eigentum von Electron von GitHub zur OpenJS Foundation. Obwohl das ursprüngliche Kernteam heute noch bei Microsoft arbeitet, sind sie nur ein Teil einer größeren Gruppe von Mitwirkenden, die die Electron-Governance bilden.²

Obwohl dieses Modell nicht perfekt ist, hat es uns gut durch eine globale Pandemie und anhaltende makroökonomische Gegenwinde gebracht. Für die Zukunft planen wir, die Governance-Charta zu überarbeiten, um uns durch das zweite Jahrzehnt von Electron zu führen.

Community​

Der Community-Teil von Open Source ist schwierig, besonders wenn dein Outreach-Team aus einem Dutzend Ingenieuren in einem Trenchcoat besteht, auf dem "Community Manager" steht. Das bedeutet jedoch, dass wir als großes Open-Source-Projekt viele Nutzer haben, und ihre Energie für Electron zu nutzen, um ein Userland-Ökosystem aufzubauen, ist ein entscheidender Teil, um die Gesundheit des Projekts zu erhalten.

Was haben wir unternommen, um unsere Präsenz in der Community zu entwickeln?

Virtuelle Community aufbauen​

• Im Jahr 2020 starteten wir unseren Community-Discord-Server. Zuvor hatten wir einen Bereich im Forum von Atom, aber wir entschieden uns für eine informellere Messaging-Plattform, um einen Raum für Diskussionen zwischen Maintainern und Electron-Entwicklern sowie für allgemeine Debugging-Hilfe zu schaffen.
• This group has been instrumental in Electron growth in users from China’s booming tech scene, providing a space for them to collaborate on ideas and discuss Electron outside of our English-language spaces. We’d also like to thank cnpm for their work in supporting Electron’s nightly releases in their Chinese mirror for npm.

Participating in high-visibility open source programs​

• We have been celebrating Hacktoberfest every year since 2019. Hacktoberfest is yearly celebration of open source organized by DigitalOcean, and we get dozens of enthusiastic contributors every year looking to make their mark on open source software.
• In 2020, we participated in the initial iteration of Google Season of Docs, where we worked with @bandantonio to rework Electron’s new user tutorial flow.
• In 2022, we mentored a Google Summer of Code student for the first time. @aryanshridhar did some awesome work to refactor Electron Fiddle's core version loading logic and migrate its bundler to webpack.

Automatisieren Sie all die Dinge!​

Today, Electron governance has about 30 active maintainers. Less than half of us are full-time contributors, which means that there’s a lot of work to go around. What’s our trick to keeping everything running smoothly? Our motto is that computers are cheap, and human time is expensive. In typical engineer fashion, we’ve developed a suite of automated support tooling to make our lives easier.

Nicht Goma​

The core Electron codebase is a behemoth of C++ code, and build times have always been a limiting factor in how fast we can ship bug fixes and new features. In 2020, we deployed Not Goma, a custom Electron-specific backend for Google’s Goma distributed compiler service. Not Goma processes compilation requests from authorized user’s machines and distributes the process across hundreds of cores in the backend. It also caches the compilation result so that someone else compiling the same files will only need to download the pre-compiled result.

Since launching Not Goma, compilation times for maintainers have decreased from the scale of hours to minutes. A stable internet connection became the minimum requirement for contributors to compile Electron!

Kontinuierliche Faktor-Authentifizierung​

Continuous Factor Authentication (CFA) is a layer of automation around npm’s two-factor authentication (2FA) system that we combine with semantic-release to manage secure and automated releases of our various @electron/ npm packages.

While semantic-release already automates the npm package publishing process, it requires turning off two-factor authentication or passing in a secret token that bypasses this restriction.

We built CFA to deliver a time-based one-time password (TOTP) for npm 2FA to arbitrary CI jobs, allowing us to harness the automation of semantic-release while keeping the additional security of two-factor authentication.

We use CFA with a Slack integration front-end, allowing maintainers to validate package publishing from any device they have Slack on, as long as they have their TOTP generator handy.

Sheriff​

Sheriff ist ein Open-Source-Werkzeug, das wir geschrieben haben, um die Verwaltung von Berechtigungen in GitHub, Slack und Google Workspace zu automatisieren.

Sheriff’s key value proposition is that permission management should be a transparent process. It uses a single YAML config file that designates permissions across all the above listed services. With Sheriff, getting collaborator status on a repo or creating a new mailing list is as easy as getting a PR approved and merged.

Sheriff also has an audit log that posts to Slack, warning admins when suspicious activity occurs anywhere in the Electron organization.

…und alle unsere GitHub Bots​

GitHub is a platform with rich API extensibility and a first-party bot application framework called Probot. To help us focus on the more creative parts of our job, we built out a suite of smaller bots that help do the dirty work for us. Here are a few examples:

• Sudowoodo automates the Electron release process from start to finish, from kicking off builds to uploading the release assets to GitHub and npm.
• Trop automates the backporting process for Electron by attempting to cherry-pick patches to previous release branches based on GitHub PR labels.
• Roller automates rolling upgrades of Electron’s Chromium and Node.js dependencies.
• Cation ist unser Statusprüfbot für electron/electron PRs.

Insgesamt hat uns unsere kleine Bot-Familie einen enormen Schub in der Entwicklungsproduktivität gebracht!

Was kommt als Nächstes?​

Wenn wir in unser zweites Jahrzehnt als ein Projekt kommen, könnten Sie fragen: Was ist das nächste für Electron?

We’re going to stay in sync with Chromium's release cadence, releasing new major versions of Electron every 8 weeks, keeping the framework updated with the latest and greatest from the web platform and Node.js while maintaining stability and security for enterprise-grade applications.

We generally announce news on upcoming initiatives when they become concrete. If you want to keep up with future releases, features, and general project updates, you can read our blog and follow our social media profiles (Twitter and Mastodon)!

Electron will end support of Windows 7, Windows 8 and Windows 8.1 beginning in Electron 23.

In line with Chromium’s deprecation policy, Electron will end support of Windows 7, Windows 8 and Windows 8.1 beginning in Electron 23. This matches Microsoft's end of support for Windows 7 ESU and Windows 8.1 extended on January 10th, 2023.

Electron 22 will be the last Electron major version to support Windows versions older than 10. Windows 7/8/8.1 will not be supported in Electron 23 and later major releases. Older versions of Electron will continue to function on Windows 7, and we will continue to release patches for Electron the 22.x series until May 30 2023, when Electron will end support for 22.x (according to our support timeline).

Why deprecate?​

Electron follows the planned Chromium deprecation policy, which will deprecate support in Chromium 109 (read more about Chromium's timeline here). Electron 23 will contain Chromium 110, which won’t support older versions of Windows.

Electron 22, which contains Chromium 108, will thus be the last supported version.

Deprecation timeline​

The following is our planned deprecation timeline:

• December 2022: The Electron team is entering a quiet period for the holidays
• January 2023: Windows 7 & 8 related issues are accepted for all supported release branches.
• February 7 2023: Electron 23 is released.
• February 8 2023 - May 29 2023: Electron will continue to accept fixes for supported lines older than Electron 23.
• May 30 2023: Electron 22 reaches the end of its support cycle.

What this means for developers:

• The Electron team will accept issues and fixes related to Windows 7/8/8.1 for stable supported lines, until each line reaches the end of its support cycle.
  • This specifically applies to Electron 22, Electron 21 and Electron 20.
• New issues related to Windows 7/8/8.1 will be accepted for Electron versions older than Electron 23.
  • New issues will not be accepted for any newer release lines.
• Once Electron 22 has reached the end of its support cycle, all existing issues related to Windows 7/8/8.1 will be closed.

What's next​

Please feel free to write to us at info@electronjs.org if you have any questions or concerns. You can also find community support in our official Electron Discord.

Das Electron-Projekt wird für den Monat Dezember 2022 pausieren und dann im Januar 2023 in voller Geschwindigkeit zurückkehren.

Warum passiert das?​

With the success of December Quiet Month 2021, we wanted to bring it back for 2022. December continues to be a quiet month for most companies, so we want to give our maintainers a chance to recharge. Alle freuen sich auf 2023, und wir erwarten gute Dinge! Wir ermutigen andere Projekte, ähnliche Maßnahmen in Erwägung zu ziehen.

Last month, Electron’s maintainer group met up in Vancouver, Canada to discuss the direction of the project for 2023 and beyond. Over four days in a conference room, core maintainers and invited collaborators discussed new initiatives, maintenance pain points, and general project health.

Going forward, the team will still be fully dedicated to releasing regular and rapid Chromium upgrades, fixing bugs, and making Electron more secure and performant for everyone. We also have a few exciting projects in the works we would love to share with the community!

Transformative new APIs​

Major API proposals in the Electron project that require consensus go through a Request for Comments (RFC) process, which gets reviewed by members of our API Working Group.

This year, we have driven forward two major proposals that have the potential to unlock a new dimension of capabilities for Electron apps. These proposals are highly experimental, but here’s a sneak peek of what to expect!

New native addon enhancements (C APIs)​

This proposal outlines a new layer of Electron C APIs that will allow app developers to write their own Native Node Addons that interface with Electron’s internal resources, similar to Node’s own Node-API. More information about the proposed new API can be found here.

Example: Supercharging apps with Chromium resources​

Many Electron apps maintain their own forks to interact directly with Chromium internals that would otherwise be inaccessible with vanilla (unmodified) Electron. By exposing these resources in the C API layer, this code can instead live as a native module alongside Electron, potentially reducing app developer maintenance burden.

Exposing Chromium’s UI layer (Views API)​

Under the hood, the non-website parts of Chrome’s user interface (UI), such as toolbars, tabs, or buttons, are built with a framework called Views. The Views API proposal introduces parts of this framework as JavaScript classes in Electron, with the eventual goal of allowing developers to create non-web UI elements to their Electron applications. This will prevent apps from having to hack together web contents.

The groundwork to make this new set of APIs possible is currently in progress. Here are a few of the first things you can expect in the near future.

Example: Refactoring the window model with WebContentsView​

Our first planned change is to expose Chrome’s WebContentsView to Electron’s API surface, which will be the successor to our existing BrowserView API (which, despite the name, is Electron-specific code unrelated to Chromium Views). With WebContentsView exposed, we will have a reusable View object that can display web contents, opening the door to making the BrowserWindow class pure JavaScript and eliminating even more code complexity.

Although this change doesn’t provide a lot of new functionality to app developers, it is a large refactor that eliminates a lot of code under the hood, simplifying Chromium upgrades and reducing the risk of new bugs appearing between major versions.

If you’re an Electron developer using BrowserViews in your app: don’t worry, we haven’t forgotten about you! We plan on making the existing BrowserView class a shim for WebContentsView to provide a buffer as you transition to the newer APIs.

Siehe: electron/electron#35658

Example: Scrollable web contents with ScrollView​

Our friends at Stack have been driving an initiative to expose the Chromium ScrollView component to Electron’s API. With this new API, any child View component can be made scrollable horizontally or vertically.

Although this new API fulfills a single smaller functionality, the team’s eventual goal is to build a set of utility View components that can be used as a toolkit to build more complex non-HTML interfaces.

Beteiligt werden​

Are you an Electron app developer interested in either of these API proposals? Although we’re not quite ready to receive additional RFCs, please stay tuned for more details in the future!

Electron Forge v6 stable release​

Since the framework’s inception, Electron’s build tooling ecosystem has been largely community-driven and has consisted of many small single-purpose packages (e.g. electron-winstaller, electron-packager, electron-notarize, electron-osx-sign). Although these tools work well, it’s intimidating for users to piece together a working build pipeline.

To help build a friendlier experience for Electron developers, we built Electron Forge, an all-in-one solution that combines all this existing tooling into a single interface. Although Forge has been in development since 2017, the project has lain dormant for the last few years. However, given community feedback on the state of build tooling in Electron, we have been hard at work on releasing the next-gen stable major version of Forge.

Electron Forge 6 comes with first-class TypeScript and Webpack support, as well as an extensible API that allows developers to create their own plugins and installers.

Bleib dran: Ankündigung kommt bald​

If you’re interested in building a project with Forge or building templates or plugins with Forge’s extensible third-party APIs, stay tuned for our official announcement on the Forge v6 stable release sometime this month!

Was kommt als Nächstes?​

Aside from the above, the team is always thinking of a bunch of exploratory projects to make the Electron experience better for app developers and end users. Updater tooling, API review processes, and enhanced documentation are other things we are experimenting with. We hope to have more news to share in the near future!

Electron 21 and later will have the V8 Memory Cage enabled, with implications for some native modules.

In Electron 21, we will be enabling V8 sandboxed pointers in Electron, following Chrome's decision to do the same in Chrome 103. This has some implications for native modules. Also, we previously enabled a related technology, pointer compression, in Electron 14. We didn't talk about it much then, but pointer compression has implications for the maximum V8 heap size.

These two technologies, when enabled, are significantly beneficial for security, performance and memory usage. However, there are some downsides to enabling them, too.

The main downside of enabling sandboxed pointers is that ArrayBuffers which point to external ("off-heap") memory are no longer allowed. This means that native modules which rely on this functionality in V8 will need to be refactored to continue working in Electron 20 and later.

The main downside of enabling pointer compression is that the V8 heap is limited to a maximum size of 4GB. The exact details of this are a little complicated—for example, ArrayBuffers are counted separately from the rest of the V8 heap, but have their own limits.

The Electron Upgrades Working Group believes that the benefits of pointer compression and the V8 memory cage outweigh the downsides. There are three main reasons for doing so:

1. It keeps Electron closer to Chromium. The less Electron diverges from Chromium in complex internal details such as V8 configuration, the less likely we are to accidentally introduce bugs or security vulnerabilities. Chromium's security team is formidable, and we want to make sure we are taking advantage of their work. Further, if a bug only affects configurations that aren't used in Chromium, fixing it is not likely to be a priority for the Chromium team.
2. It performs better. Pointer compression reduces V8 heap size by up to 40% and improves CPU and GC performance by 5%–10%. For the vast majority of Electron applications which won't bump into the 4GB heap size limit and don't use native modules that require external buffers, these are significant performance wins.
3. It's more secure. Some Electron apps run untrusted JavaScript (hopefully following our security recommendations!), and for those apps, having the V8 memory cage enabled protects them from a large class of nasty V8 vulnerabilities.

Lastly, there are workarounds for apps that really need a larger heap size. For example, it is possible to include a copy of Node.js with your app, which is built with pointer compression disabled, and move the memory-intensive work to a child process. Though somewhat complicated, it is also possible to build a custom version of Electron with pointer compression disabled, if you decide you want a different trade-off for your particular use case. And lastly, in the not-too-distant future, wasm64 will allow apps built with WebAssembly both on the Web and in Electron to use significantly more than 4GB of memory.

Häufig gestellte Fragen​

How will I know if my app is impacted by this change?​

Attempting to wrap external memory with an ArrayBuffer will crash at runtime in Electron 20+.

If you don't use any native Node modules in your app, you're safe—there's no way to trigger this crash from pure JS. This change only affects native Node modules which allocate memory outside of the V8 heap (e.g. using malloc or new) and then wrap the external memory with an ArrayBuffer. This is a fairly rare use case, but some modules do use this technique, and such modules will need to be refactored in order to be compatible with Electron 20+.

How can I measure how much V8 heap memory my app is using to know if I'm close to the 4GB limit?​

In the renderer process, you can use performance.memory.usedJSHeapSize, which will return the V8 heap usage in bytes. In the main process, you can use process.memoryUsage().heapUsed, which is comparable.

What is the V8 memory cage?​

Some documents refer to it as the "V8 sandbox", but that term is easily confusable with other kinds of sandboxing that happen in Chromium, so I'll stick to the term "memory cage".

There's a fairly common kind of V8 exploit that goes something like this:

1. Find a bug in V8's JIT engine. JIT engines analyze code in order to be able to omit slow runtime type checks and produce fast machine code. Sometimes logic errors mean it gets this analysis wrong, and omits a type check that it actually needed—say, it thinks x is a string, but in fact it's an object.
2. Abuse this confusion to overwrite some bit of memory inside the V8 heap, for instance, the pointer to the beginning of an ArrayBuffer.
3. Now you have an ArrayBuffer that points wherever you like, so you can read and write any memory in the process, even memory that V8 normally doesn't have access to.

The V8 memory cage is a technique designed to categorically prevent this kind of attack. The way this is accomplished is by not storing any pointers in the V8 heap. Instead, all references to other memory inside the V8 heap are stored as offsets from the beginning of some reserved region. Then, even if an attacker manages to corrupt the base address of an ArrayBuffer, for instance by exploiting a type confusion error in V8, the worst they can do is read and write memory inside the cage, which they could likely already do anyway. There's a lot more available to read on how the V8 memory cage works, so I won't go into further detail here—the best place to start reading is probably the high-level design doc from the Chromium team.

I want to refactor a Node native module to support Electron 21+. How do I do that?​

There are two ways to go about refactoring a native module to be compatible with the V8 memory cage. The first is to copy externally-created buffers into the V8 memory cage before passing them to JavaScript. This is generally a simple refactor, but it can be slow when the buffers are large. The other approach is to use V8's memory allocator to allocate memory which you intend to eventually pass to JavaScript. This is a bit more involved, but will allow you to avoid the copy, meaning better performance for large buffers.

To make this more concrete, here's an example N-API module that uses external array buffers:

// Create some externally-allocated buffer.
// |create_external_resource| allocates memory via malloc().
size_t length = 0;
void* data = create_external_resource(&length);
// Wrap it in a Buffer--will fail if the memory cage is enabled!
napi_value result;
napi_create_external_buffer(
    env, length, data,
    finalize_external_resource, NULL, &result);

This will crash when the memory cage is enabled, because data is allocated outside the cage. Refactoring to instead copy the data into the cage, we get:

size_t length = 0;
void* data = create_external_resource(&length);
// Create a new Buffer by copying the data into V8-allocated memory
napi_value result;
void* copied_data = NULL;
napi_create_buffer_copy(env, length, data, &copied_data, &result);
// If you need to access the new copy, |copied_data| is a pointer
// to it!

This will copy the data into a newly-allocated memory region that is inside the V8 memory cage. Optionally, N-API can also provide a pointer to the newly-copied data, in case you need to modify or reference it after the fact.

Refactoring to use V8's memory allocator is a little more complicated, because it requires modifying the create_external_resource function to use memory allocated by V8, instead of using malloc. This may be more or less feasible, depending on whether or not you control the definition of create_external_resource. The idea is to first create the buffer using V8, e.g. with napi_create_buffer, and then initialize the resource into the memory that has been allocated by V8. It is important to retain a napi_ref to the Buffer object for the lifetime of the resource, otherwise V8 may garbage-collect the Buffer and potentially result in use-after-free errors.

Electron is changing its primary S3 bucket, you may need to update your build scripts

What is happening?

A significant amount of Electron's build artifacts are uploaded to an S3 bucket called gh-contractor-zcbenz. As part of ongoing infrastructure/ownership migrations that started way back in 2020, we will be changing everything that used gh-contractor-zcbenz from its old home in S3 to a new storage system hosted at https://artifacts.electronjs.org. The path prefix that most of our assets use is changing slightly as well. Examples are included below:

Before: https://gh-contractor-zcbenz.s3.amazonaws.com/atom-shell/dist/v17.0.0/node.lib After: https://artifacts.electronjs.org/headers/dist/v17.0.0/node.lib

The important things here are the Hostname changed and the /atom-shell prefix changed. Another example, this time for debug symbols:

Before: https://gh-contractor-zcbenz.s3.amazonaws.com/atom-shell/symbols/path/to/symbol.pdb After: https://artifacts.electronjs.org/symbols/path/to/symbol.pdb

Again, the hostname changed and the /atom-shell prefix was changed.

How might this impact you?

Anyone using standard build tooling such as electron-rebuild, electron-packager or @electron/get won't have to do anything. This should be the majority of people.

For anyone directly referencing the S3 bucket, you must update your reference to point at the hostname and update the path as well.

What about existing data?

Most data that existed on the gh-contractor-zcbenz bucket has been cloned into the new storage system. This means all debug symbols and all headers have been copied. If you relied on some data in that bucket that hasn't been copied over please raise an issue in electron/electron and let us know.

The current gh-contractor-zcbenz S3 bucket will not be actively deleted. However, we can't guarantee how long that bucket will be left alive. We strongly recommend updating to target the new bucket as soon as possible.

Das Electron-Projekt wird für den Monat Dezember 2021 pausieren und dann im Januar 2022 in voller Geschwindigkeit zurückkehren.

Warum passiert das?​

Kurz gesagt, während die Betreuer zufrieden sind und sich mit dem Projekt beschäftigen, ist DIE WELT MÜDE. Der Dezember ist ein ruhiger Monat für die meisten Firmen, deshalb wollen wir unseren Betreuern die Möglichkeit geben, sich wieder aufzuladen. Wir ermutigen andere Projekte, ähnliche Maßnahmen in Erwägung zu ziehen.

Sollte ich über die Zukunft von Electron besorgt sein?​

Nein. Wir sind in der Lage, diesen Schritt zu gehen, weil das Projekt in guter Form ist. Alle freuen sich auf 2022, und wir erwarten gute Dinge!

Ab September 2021 wird Electron alle 8 Wochen eine neue stabile Version veröffentlichen.

In 2019, Electron moved to a 12 week release cycle to match Chromium's 6 week release cycle. Recently, both Chrome and Microsoft announced changes that made us reconsider Electron's current release cadence:

1. Chromium plans to release a new milestone every 4 weeks, starting with Chrome 94 on September 21st, 2021. This release cadence also adds a new Extended Stable option every 8 weeks, which will contain all updated security fixes.

2. The Microsoft Store will require Chromium-based apps to be no older than within 2 major versions. As an example, if the latest released major version of Chromium is 85, any browser based on Chromium must be on at least Chromium version 83 or higher. This rule includes Electron apps.

Beginning in September 2021, Electron will release a new major stable version every 8 weeks, to match Chromium's 8 week Extended Stable releases.

Our first release with Chromium Extended Stable will be Electron 15 on September 21st, 2021.

Knowing that a release cadence change will impact other downstream applications, we wanted to let our developer community know as soon as possible. Read on for more details about our 2021 release schedule.

Electron 15: Temporäre Alpha​

Given that our original Electron 15 release targeted a non-Extended Stable version (Chromium's Extended Stable versions are based on their even-numbered versions), we needed to change our original target release date. However, an Electron app must use the most recent 2 major versions of Chromium to be accepted to the Microsoft Store, which made waiting for two Chromium versions untenable.

With these two requirements, our team faced a timing dilemma. Moving Electron 15 to include Chromium M94 would allow app developers to get on the very first Extended Stable version of Chromium; however, it would also shorten the beta-to-stable cycle to only 3 weeks.

To help with this switchover, Electron will offer a temporary alpha build, only for the Electron 15 release. This alpha build will allow developers more time to test and plan for an Electron 15 release, with a more stable build than our current nightlies.

The alpha channel build will ship for Electron 15 on July 20th, 2021. It will transition to a beta release on September 1st, 2021 with a stable release target of September 21st, 2021. Subsequent Electron releases will not have alpha releases.

2021 Plan für Veröffentlichungen​

Unten ist unser aktueller Release-Zeitplan für 2021:

Adding the alpha channel extends the development time before Electron 15's launch from 3 weeks to 9 weeks - closer to our new 8 week cycle, while still meeting the requirements for Windows Store submission.

To further help app developers, for the remainder of 2021 until May 2022, we will also be extending our supported versions policy from the latest 3 versions to the latest 4 versions of Electron. That means that even if you can't immediately alter your upgrade schedule, older versions of Electron will still receive security updates and fixes.

Bedenken ausräumen​

There's a reason we're publishing this post well before this release cycle change is scheduled. We know that a faster release cycle will have a real impact on Electron apps - some of which may already find our major release cadence aggressive.

Wir haben versucht, die folgenden Anliegen zu berücksichtigen:

❓ Warum überhaupt diese Änderung vornehmen? Warum nicht die 12 Wochen Kadenz behalten?​

To deliver the most up-to-date versions of Chromium in Electron, our schedule needs to track theirs. More information around Chromium's release cycle can be found here.

Additionally, the current 12 week release cadence would be untenable with the Microsoft Store's new submission requirements. Even apps on the latest stable version of Electron would experience a roughly two week period where their app may be rejected under the new security requirements.

Every new Chromium release contains new features, bug fixes / security fixes, and V8 improvements. We want you, as app developers, to have these changes in a timely manner, so our stable release dates will continue to match every other Chromium stable release. As an app developer, you'll have access to new Chromium and V8 features and fixes sooner than before.

❓ The existing 12 week release schedule already moves quickly. What steps are the team taking to make upgrading easier?​

One advantage of more frequent releases is having smaller releases. We understand that upgrading Electron's major versions can be difficult. We hope that smaller releases will introduce fewer major Chromium and Node changes, as well as fewer breaking changes, per release.

❓ Wird es für zukünftige Electron-Versionen eine Alpha-Version geben?​

Es gibt derzeit keine Pläne, eine dauerhafte Alpha-Version zu unterstützen. Diese Alpha ist nur für Electron 15 gedacht, um den Entwicklern bei der Aktualisierung in der verkürzten Release-Periode zu helfen.

❓ Wird Electron die Anzahl der unterstützten Versionen verlängern?​

We will be extending our supported version policy from the latest three versions to the latest four versions of Electron until May 2022, with the release of Electron 19. After Electron 19 is released, we'll return to supporting the latest three major versions, as well as the beta and nightly releases.
