This week's release includes BYOK support for GPT-6.1 Sol, on-the-fly model selection for new subagents, automatic subagent compaction, a unified/split toggle for diffs opened from the command line, and dynamically fetched OpenCode models.

Features

AI

• Added an optional model parameter to spawn_agent to choose a model for that spawn instead of using the configured subagent model or inheriting the parent model, with the active model shown in its card. (#64498; thanks itsfuad)
• Added BYOK support for GPT-6.1 Sol with an OpenAI API key. (#64968; thanks ktKongTong)

• Fixed Command-clicking a symbol opening a definitions multibuffer instead of the picker when lsp_results_location was set to "picker". (#64039; thanks v-shevtsov)

Breaking Changes and Notices

• Removed Stop controls from external-agent-managed terminals, which are controlled by the agent rather than a local process. (#64544)
• Changed Threads Sidebar settings to agent.threads_sidebar.position, agent.threads_sidebar.default_width, and agent.threads_sidebar.auto_open, grouped together in the Settings Editor. Existing settings are migrated automatically. (#64395; thanks joshkent94)

Stijn Bronzwaer schuift aan met een ongeautoriseerde biografie van Ali Niknam, volgens hem de meest succesvolle ondernemer die Nederland op dit moment heeft. Drie bedrijven van meer dan een miljard, waaronder Bunq, en een managementstijl die volgens een Silicon Valley-kenner eerder Chinees is dan Amerikaans. We lopen de anekdotes langs: het pak melk dat buiten de koelkast bleef staan waarna het hele kantoor twee weken zonder zat, de honkbalknuppel van twee meter met “is het al af?” erop en de sollicitant die op de wc werd bijgeleerd hoe je één papieren handdoekje gebruikt.

En toen ging het over de phishingzaak. Klanten die in twintig minuten een ton kwijtraakten en bij een chatbot terechtkwamen die hen een fijne dag wenste. Voor het eerst een strijd die Niknam verloor.

Ondertussen kantelt het gesprek naar de journalistiek zelf. Alexander en Ernst zaten allebei ooit aan de andere kant en herkennen te veel. Waarom staat “maar lijdt nog verlies” altijd in de kop? Waar is de nieuwsgierigheid naar hoe het iemand wél lukt? Stijn houdt vol dat CEO’s gewoon niet gewend zijn aan een journalist die zich echt heeft voorbereid. Het boek kost NRC overigens meer aan advocaten dan het ooit oplevert.

Het boek van Stijn Bronzwaer, Joris Kooiman en Merijn Rengers is hier te bestellen: https://nrcwebwinkel.nl/ali-niknam-stijn-bronzwaer-joris-kooiman-merijn-rengers-9789083629605

New

• 

  Firefox's biggest visual refresh in years is now available, with a modernized look across the browser toolbars, sidebar, menus and individual features, built with our updated design system. It also includes:

  • New built-in themes with light and dark versions, to personalize the look of Firefox in one click.
  • A new compact mode that reduces toolbar and tab spacing to leave more room for web content, useful on smaller screens and in split-screen layouts.

• WebRTC video calls can now use hardware AV1 decoding on devices that support it, instead of always decoding AV1 video in software.

• Firefox now shows a warning in the site information panel (the shield icon in the address bar) and in Settings when it has been set up to record its encryption keys, which could let other software on the computer read encrypted web traffic.
  

• Firefox Suggest now offers suggestions in the address bar in Austria, Belgium, Czech Republic, Denmark, Finland, Hungary, Ireland, Luxembourg, Netherlands, Norway, Poland, Portugal, Slovakia, Spain, Sweden, and Switzerland. They can be controlled in the Firefox Suggest settings. Learn more.

Fixed

• Fixed video from phones and tablets appearing sideways or upside down in WebRTC calls.

• Fixed the address bar searching for the typed text instead of opening the selected suggestion when a page was still loading, such as shortly after Firefox started.

• Fixed some HDR videos encoded in 8-bit color formats looking dull and gray on Windows instead of displaying in HDR.

• Improved audio and video synchronization when repeatedly changing the playback speed of videos, for example on YouTube.

• Fixed the Vertical Tabs sidebar not reappearing when the cursor moves to the edge of the screen in full screen mode.

• Fixed an issue on Windows where making a video full screen would leave the Windows taskbar showing over the video.

• Various security fixes.

Changed

• Pressing Tab now moves focus straight to the text field of the address bar and search bar instead of stopping on the search engine button first. The button can still be reached with Shift+Tab.

• Amazon is no longer included as a built-in search engine. It can still be added as a custom search engine in the search settings. Learn more.

• The updated sidebar is now enabled for everyone. Anyone still using the previous sidebar will keep a similar layout, with the panel switcher at the top of the sidebar. Additionally, the “Show sidebar” option has been removed from Settings.

  While we continue to refine the new design, the previous sidebar version can still be restored by setting sidebar.revamp to false in about:config. This also turns off vertical tabs. The preference will remain available until the end of 2027.

• Web page alert(), confirm() and prompt() dialogs, the color and date pickers, and form autocomplete drop-downs now match the page's light or dark color scheme.

Enterprise

• You can find information about policy updates and enterprise-specific bug fixes in the Firefox for Enterprise 157 Release Notes.

Developer

• Developer Information

Web Platform

• Firefox now supports the at-rule() function for @supports. This allows authors to detect browser support for specific at-rules, such as @supports at-rule(@scope).

• Firefox now supports the chain value for the CSS overscroll-behavior property.

Full Changelog: v0.20.0-rc.6...v0.20.0-rc.7

We are super excited that the day many of you have been waiting for has finally arrived. Today, you can get ready to drive a new set of vehicles with the release of the Road Trip: Ford DLC for American Truck Simulator!

The Road Trip: Ford DLC is now released and available on Steam!

We first announced project Road Trip in April last year, and since then, it has been eagerly awaited by our #BestCommunityEver. A dedicated team was formed to bring this brand-new experience to American Truck Simulator, working closely with our vehicle team, programmers, testers, and many other colleagues across the company. The Ford DLC is the first release from the Road Trip project, and we're incredibly happy to finally bring it to our community!

Now, you can hit the open roads of American Truck Simulator like never before with this DLC as you take the wheel of:

• The iconic 1967 Ford Mustang Fastback
• The all-purpose 2023 Ford F-150
• The modern 2023 Ford Bronco
• and the legendary 1998–2012 Ford Crown Victoria

With the Road Trip: Ford DLC, you will unlock Car Mode, its related features, and all of these personal cars, which you can take out on the road and experience American Truck Simulator from a whole new perspective. Customise your vehicles with a variety of accessories and paint options, then hit the road and explore at your own pace.

Looking for something to do along the way? Take on smaller deliveries through Quick Jobs or the Dispatch Market and build your courier reputation, or discover the world around you with the new Atlas feature. Visit iconic locations, learn more about them, and collect beautifully designed postcards as you explore.

At release, the Atlas feature and its Tourist Boards will be available in California, and in the Oregon, Washington, Idaho, Montana, Wyoming, and South Dakota DLCs. The remaining states will be gradually included in future updates.

Step away from your big rig and get behind the wheel of iconic Ford vehicles, a fresh way to explore the world of American Truck Simulator. You can also team up with your friends in Convoy mode and hit the road together, with trucks and cars sharing the highways! And don't forget that if you own this DLC, you can also enjoy the Atlas feature from behind the wheel of a truck.

We're happy to have partnered with Ford to bring these iconic vehicles to life in American Truck Simulator, and we would like to thank them very much for their cooperation in making this possible. 

But now, it's all up to you - we can't wait to see where your next road trip takes you!

Release Live Stream

As we always do with our map expansions, we also plan to introduce the new Road Trip: Ford DLC to our community with a special release stream! Starting today at 3 pm CEST, we'll be joined by guests who worked on the DLC's development, chatting with them about the process while taking Ford cars out on the roads of American Truck Simulator. And at the end of the stream, we'll officially release the DLC together with you!

Make sure to share photos or videos from your road trip journeys with us on social media by tagging us on X/Twitter, Facebook, BlueSky, and Instagram. For more news from American Truck Simulator and further Road Trip development, don't forget to subscribe to our newsletter or follow us on our social media accounts. We will see you on the road!

Security:

• Fixed script injection in event scripts. With JScript, untrusted values passed to event handlers (such as the logon password in OnClientValidatePassword, or error text and UIDs sent by remote servers) could break out of their string. With either script language, a rule's "Run function" name could carry code. This would allow an attacker to run arbitrary code in the hMailServer process. Values are now escaped, and rule function names may only contain letters, digits and underscores.

If you are unable to install this version, disable JScript execution and do not give end-users access to the hMailServer COM API.

release: v2.0.19

Part-DB 2.19.2

Bug fix

• Fixed step 3D model viewer colors when one part contains multiple colors

Various changes

• Update KiCad symbols and footprints lists by @jbtronics in #1562
• Updated translations
• Updated dependencies

Full Changelog: v2.19.1...v2.19.2

• [p]Fixed pixel-gaps in various Rush rooms.[/p][/*]
• [p]Clipping adjustments in T/CT Castle rooms.[/p][/*]

Highlights

• Rév O’Conner added a settings popup to control the layout of the Inspector. “Auto” automatically switches the layout at a given toolbox width.
  • 
• The new sidebar (sidebar.revamp) and switcher setting will be enabled by default for users along with Nova in DevEdition, Beta and Release channels. To ease the transition for old sidebar users, the “Open tools from sidebar” option will be unchecked for those users to more closely resemble the old sidebar experience. The migration won’t apply to users who had already tried the new sidebar and reverted back.
• The custom wallpaper library for the New Tab page is coming along! This allows you to save multiple images to your wallpaper folder, rather than replacing one image at a time. While it’s still in development, you can test it by setting browser.newtabpage.activity-stream.newtabWallpapers.customWallpaper.library.enabled to true, starting in Firefox 157.
  • 
• Mark added an MDN search engine for Nightly and Developer Edition. Select it from the menus, or type @mdn <search term>.

DevTools

• The team has a few sizable ongoing projects.
  • Bomsy is working on moving Stylesheets to the Debugger so we can retire the (XUL-based) Style Editor, and turn the Debugger into a “Sources” panel (keeping all the existing functionality of course).  (pref: devtools.debugger.features.stylesheets-in-debugger)
  • Alex is investigating ways to better handle CSS authored text and CSSOM changes in the Inspector, building information directly from the Rust CSS engine, with the hope it will bring performance improvement editing styles in the Rules view.
  • Nicolas is implementing a way to show to the user how the engine goes from a CSS declaration value to the computed value so it’s easier to follow what’s the result of the different call sites, or how the different units (em, %, vmin, …) are computed to their final (e.g. px) values.   (pref: devtools.inspector.css-explainers)

External contributions

Team/Project Update

• Florian Quèze [:florian] is working on fixing test flakiness in devtools/client/debugger and already landed an impressive stack of patches (#2001947, #2070917, #2070920, #2070932, #2070970, #2027953, #1932082, #2070923, #2070933, #1814093, #1868969, #2071238)
  • that also includes fixing various accessibility issues that were spotted by a11y_checks #2070911, #2070955, #2071227, #2071231)
  • Note that Julian Descottes [:jdescottes] also has an ongoing quest to reduce intermittent failures in our codebase and fixed a few those last 2 weeks (#1767707, 2069100, #2009386)
  • [florian] 24 patches landed on Friday, you can see the impact on https://tests.firefox.dev/tests.html?path=devtools%2Fclient%2Fdebugger
• Nicolas Chevobbe [:nchevobbe] fixed a few issues spotted by Jake in the Inspector for the new-ish attr()CSS function (#2068479, #2068480, #2068483)
• Alexandre Poirot [:ochameau] fixed an OOM crash when viewing source mapped file for a large wasm module with many workers (#2058286)
• Julian Descottes [:jdescottes] improved performance of the Inspector when Devtools was opened on a page with many grid elements (#1988868)
• Hubert Boma Manilla (:bomsy) fixed an infinite loop in the Debugger search if you were searching for $ on a big JS file (#2068517)

WebDriver

• Sameem merged two internal helpers (remote/shared/Sync.sys.mjs and remote/marionette/sync.sys.mjs) which removed some code duplication.
• Khalid AlHaddad unified the navigation commands in Marionette and WebDriver BiDi to always initiate navigations via browsingContext.loadURI().
• Khalid AlHaddad updated the WebDriver BiDi client used by WebDriver tests so that browsing_context.locate_nodes returns the nodes array directly instead of the enclosing result object, matching the updated command response.
• Julian Descottes made the destinationFolder mandatory when calling the browser.setDownloadBehavior command with type=”allowed” – which aligns us with the specification. In order to restore the default behavior without having to specify a folder, clients should call setDownloadBehavior with null instead.
• Henrik Skupin fixed a bug in geckodriver where specifying androidIntentArguments in the capabilities caused the default intent arguments to be omitted.

Fluent

• According to arewefluentyet.com, ~74.77% of our strings are now using Fluent!

Lint, Docs and Workflow

• According to arewemozsrcyet.com, ~59% of our modules are now using moz-src.
• eslint-plugin-mozilla has switched from using Mocha to Jest for tests.
  • Planning on future updates to investigate getting devtools & newtab to use the jest installed at the top-level, rather than separately installed copies.

Information Management/Sidebar

• We’re working away on bug fixes for sidebar, vertical tabs, split-view, and Nova
• Thanks Florian (:fqueze) for landing a set of patches that have markedly reduced test flakiness in the Sidebar component

New Tab Page

• Custom wallpaper library
  • Dre added a “Your images” folder to the wallpaper picker on the New Tab Page, letting users save and switch between multiple custom wallpapers directly from the picker UI (desktop channels), which reduces friction for users who frequently change backgrounds.
  • Dre implemented storage and migration for multiple custom wallpapers so users keep their existing wallpaper during upgrade while gaining the ability to save and switch multiple wallpapers — migration moves old single-wallpaper prefs into the new multi-wallpaper storage and the NTP now reads the wallpaper array at load/sync points.
  • Dre updated New Tab Page strings to support multiple custom wallpapers so users now see accurate, localized labels and accessibility text when managing or switching between multiple custom backgrounds, reducing confusion in the UI during wallpaper selection.
  • Dre added a delete affordance for saved custom wallpapers inside the New Tab Page picker so users can remove unwanted images from their saved set without going to profile files or prefs, improving manageability of user-provided wallpapers.
• We’ve completed a mass migration of our unit tests from Mocha (not mochi) / Karma to Jest/RTL, which is more modern and actively maintained.
• Sections is now enabled globally for all regions that show the content feed!
• Reem Hamoui fixed Lists widget so that keyboard users can now tab to completed items on the New Tab Page and see a visible selection/focus state
• Reem Hamoui fixed the Timer widget so that keyboard users can toggle focus vs break modes with standard keys (Enter/Space/arrow keys) thanks to restored keyboard handlers and tabindex semantics.
• Reem Hamoui made it so that screenreaders now announce wallpaper names via added aria-labels/alt text and role improvements in the Customize UI.
• Maxx Crawford made it so that the Customize UI now filters wallpapers by their metadata and no longer surfaces images marked hidden or in specific visibility groups.
• Irene Ni added Section Layout Name (String) telemetry to newtab content impression & click events so impressions/clicks now carry layout identifiers for more granular UX and A/B analysis
• Reem Hamoui added accessible names (aria-label/aria-labelledby) to the HNT Customize panel back buttons to fix screen-reader discoverability and keyboard/AT announcement when navigating the New Tab Customize flow.
• Nina Pypchenko [:nina-py] preserved iframe rendering for New Tab Page widgets during drag operations to prevent iframe-backed widgets from going blank while being moved.
• Nina Pypchenko [:nina-py] restored the Stocks widget dropdown and menu visibility under High Contrast Mode by adjusting contrast-aware CSS and ARIA roles so users relying on HCM can access stock controls again.
• Nina Pypchenko [:nina-py] fixed a results text overflow for long search queries in the Stocks widget by adding word-wrap/clamping to result lines, preventing layout breakage and truncated controls when users enter long symbols or queries.
• Nina Pypchenko [:nina-py] added telemetry for theme selection in the New Tab customization panel by emitting a selection ping on change, enabling measurement of user theme choices without changing UX.
• Irene Ni restored the Lists widget switcher checkmark for the selected list by fixing menu item selection-state rendering so users can again see which list is active in the switcher.
• Reem Hamoui updated the Privacy widget CTA and spacing on the New Tab Page, adjusting CSS/layout and CTA copy so the action is more discoverable and has a clearer tap/click target across responsive breakpoints.
• Reem Hamoui updated the zero-state copy for the New Tab Privacy widget to clarify what the widget does and the next steps for users when no privacy events or trackers are present, reducing confusion for first-time or cleared-state users.
• Maxx Crawford landed Fluent strings for the Nova launch New Tab customization callout, enabling localized text in the New Tab customization callout so users in supported locales see translated UI instead of missing-string fallbacks.
• Nina Pypchenko made the customization panel reset when closed, ensuring about:newtab customization state (temporary tile/layout previews) is cleared on close so users no longer see stale previews when reopening the panel.
• Dão Gottwald fixed New Tab to pick up system High Contrast Mode on Linux and macOS, restoring correct high-contrast colors/contrast on those platforms for users who rely on OS-level accessibility settings.
• Irene Ni restored theme matching for New Tab context menus by reapplying theme-aware CSS variables in the New Tab Page contextmenu styles, fixing mismatched colors for users with custom/light/dark themes.
• Dustin Whisman fixed New Tab section context menu button color regression by adjusting the section-contextmenu button style rules (button color variables and state selectors) so section actions now respect theme contrast.
• Irene Ni restored transparency to New Tab card backgrounds by removing opaque background rules so cards correctly display background images/themes and improve visual consistency across DPI/compositing setups.

Picture-in-Picture

• Thanks to Sebastian Zartner [:sebo] for fixing broken Dailymotion captions on the PiP player.
• kpatenio fixed YouTube’s displayed playback speed settings being out of sync with PiP.
  • Reminder that the playback speed settings can be enabled with media.videocontrols.picture-in-picture.playback-speed.enabled.
  • 
• Thanks to Sylvestre Ledru [:Sylvestre] for helping fix a broken link in our PiP docs as a part of Bug 2071683.
