Release summary
Editorial Signals are a layer of human-controlled ranking rules that sit on top of the Content Recommendations API's machine-learned recommendations.
They let your newsroom override, nudge, or filter the model's output without retraining anything — the changes take effect on the very next recommendation request.
In short: AI decides what is likely to engage a given reader; signals decide what is editorially required for that reader to see (or not see).
Signals are exposed through a dedicated service — the Signals API (/signals/v1).
The four signal types
There are four distinct signal types. Each one answers a different editorial question.
Signal type | Editorial question | Effect on the ranked list |
|---|---|---|
Boost | "I want this to do better than the model thinks it will." | Multiplies the item's AI score by a weight between 1.0 and 10.0. Item rises naturally in the ranking. |
Bury | "I want this to do worse than the model thinks it will." | Multiplies the item's AI score by a weight between 0.0 and 0.9. Item falls in the ranking but isn't removed. |
Pin | "This item must appear at position N." | Forces the item into a specific 1-indexed slot, even if the content was not included in the preliminary candidate set. An absolute position override. |
Exclude | "This item must not appear at all, regardless of relevance." | Removes the item from the candidate set entirely. Takes precedence over every other signal, including Pin. |
These controls are currently API only. A user experience will be added in an upcoming release.

Release summary
We're excited to announce that Audio Articles and Translation capabilities are now available directly inside Composer as part of the AI Assistant — no Chrome extension required– for customers on the Core Arc Intelligence Package.
Audio Articles
You can now generate a text-to-speech (TTS) audio file for any story and add it inline — directly from Composer. This is a significant improvement over the previous Chrome extension experience, which required manually copying an embed code into an HTML element. The new workflow adds the audio file directly to Audio Center as well, so you can centrally manage all your audio files in one place.
Translations
You can now translate a story directly in Composer — either in place or as a cloned version of the original. The AI Assistant will translate headline, subheadline, and body text content automatically. Note that metadata, images, and embeds will not be affected at this point in time.
Supported languages: English, Spanish, French, Japanese, Korean, and German.
The release also addresses a few other updates in Composer including:
An issue where subtype field was incorrectly saving the label instead of the ID causing some intermittent issues
An IFX issue has been resolved where images weren’t being received when a composer publish event also published a photo.

Summary
We are excited to announce the Open Beta of the Content Recommendations API, Arc XP's new personalization platform for media companies. Participating customers will receive six months of free access to the API (and an IFX integration used to ingest content) and can use it to power personalized site, app, and email experiences that drive deeper engagement with their audience.
This doc summarizes what's available today, what it takes to get started, and what's on the roadmap.
What's available in the initial release
The Content Recommendations API is a personalization service that learns from your content catalog and audience behavior to return ranked content recommendations on demand. Each customer operates with their own fully isolated recommendation model: content, audience data, and the trained model are never shared across tenants.
The initial release supports two core recommendation types:
Personalized recommendations for a user overall — given a user identifier, the API returns a ranked list of content items tailored to that user's interaction history. Ideal for a “For You” module on a home page or a personalized section in a newsletter.
“More like this” recommendations in the context of a specific piece of content — given both a user and an anchor article, the API returns items similar to the anchor but still personalized to the reader. Ideal for an end-of-article or in-article recirculation module.
Cold-start behavior is handled automatically. New or anonymous users receive popularity-weighted results until they accumulate interaction history, and newly published content is eligible for recommendations immediately based on its metadata, no special handling required on the customer's side.
What participating customers need to do
The API is the personalization backend only. To put recommendations in front of readers, each participating customer is responsible for two integration workstreams:
Connecting their Customer Data Platform (CDP) to send behavioral events (page views, clicks, shares, engaged reads, scroll depth, and similar signals) to the Collector API. A richer event stream produces stronger personalization. More information about the Collector API can be found here.
Building the front-end UI that surfaces recommendations to readers — for example, a “For You” module on the home page, a recirculation rail on article pages, or a personalized section in an email template. The API returns ranked content IDs; the customer hydrates them from their CMS and renders the experience. More information about the recommendations API can be found here.
Arc XP CMS customers can use an IFX recipe to wire up the content webhook end-to-end without custom code. Non-Arc XP CMS customers will need to build a direct integration from their CMS to the Collector API's content endpoint.
A full onboarding checklist is available on the Arc XP for Developer site.
What's coming next
This initial release is only the foundation and we have significant functionality slated for release over the coming weeks and months. Planned updates include additional filtering and personalization controls, stronger editorial controls, and deeper integration hooks. Customers who join the beta now will benefit from those additions as they ship, within their six-month free access window.
Getting Started
Talk with your Technical Account Manager about enrolling in this beta. The free access beta is limited to customers who begin their beta engagement in May 2026.

Arc XP is excited to announce that we now have a new addition to our Edge Integration Framework.The integration detects known LLM user agents at the edge and redirects eligible requests to a customer-owned Tollbit subdomain, where Tollbit manages authorization, billing, metering, transformation, and optional caching. Non-LLM traffic continues through the standard Arc delivery path with no behavioral change.
This guide outlines the steps necessary to enable Tollbit’s bot monetization solution with Arc XP.
Below is a step-by-step implementation guide to enable the Arc XP + TollBit Edge Integration.
Tollbit:You have created a Tollbit account with Tollbit
Arc XP: Submit an ACS ticket to request the tollbit subdomain creation for EACH SITE where you would like the integration. ACS Ticket Example:
Org: Your Org name
Sites: examplesite1, examplesite2
Environment: Prod
Change type: Add
Sample %: 100
Push frequency: 30 sec
Integration type: Direct feed from CDN → TollBit
A TollBit subdomain must exist for each site and is correctly configured via CNAME.
Arc will also need a Tollbit provided API key. This key should be submitted to Arc via secure methods.
For each site
Create the subdomain:
tollbit.site1.comtollbit.site2.comtollbit.site3.com
Add the CNAME record(s) pointing to the TollBit-provided target (TollBit will give you the exact hostname).
Example format :
tollbit.<site> CNAME <tollbit-target-hostname>
Verify property ownership through DNS verification:
Once you create a property, we need to verify your ownership of the domain before we can continue with your TollBit integration. Verifying a Property
Confirm propagation:
DNS resolves correctly
TLS/cert is valid (your CDN/edge stack may need SAN coverage depending on how hostnames are managed)
Note: The Arc edge integration forwards LLM traffic to tollbit.*, so the hostname must work before you flip traffic.
Repeat these steps for each site in the desired Arc environment (Prod, Staging, etc).
Open Delivery UI → Edge Integrations for the site.
Select View for the site you wish to configure and then select Edge Integrations
Scroll down to the Tollbit integration and enable the toggle on the righthand side
Should you wish to override the list of enabled/disabled bots configured directly in Tollbit you can provide a comma delimited override list in the Arc UI.
Submit an ACS ticket to Arc so that a DataStream can be created in Akamai to provide Tollbit the site analytics information necessary to make their reporting fully functional. Integrations
Once fully enabled, using the steps above, Tollbit’s Dashboard provides a list of analytics, insights and configuration controls.
The Tollbit Dashboard also provides the ability to Allow or Block Bots. Remember, if you provide a list of allowed Bots in Arc it will override any selections in Tollbit. If you want to manage bot access directly in Tollbit make your sections in their UI and leave the override list blank in Arc.

Release summary
The AI Assistant has officially arrived in Composer — bringing intelligent, real-time editorial support directly into the publishing workflow. Designed to work alongside authors, the AI Assistant helps newsroom teams move faster, publish smarter, and maintain consistent standards — all without disrupting how they work today. From metadata optimization to style guidance and content enhancements, it acts as an integrated publishing partner embedded exactly where content gets created.For Arc Intelligence customers, this unlocks a more streamlined, standards-driven publishing experience — with flexibility and control built in from day one.
What the AI Assistant delivers
The AI Assistant is built around three core editorial workflows designed to improve quality, consistency, and performance directly inside Composer.
Metadata Review: Ensures every story is optimized before it’s published.
Supports: Headlines, Tags, SEO keywords, Descriptions
Admins can choose whether metadata updates are automatically applied or surfaced as suggestions for review.
All AI-generated changes are clearly labeled, with visual indicators to ensure transparency and control.
Style Guide Suggestions: The AI Assistant provides real-time editorial and stylistic recommendations aligned to your organization’s standards — helping authors meet expectations before stories move into review.
Reduce repeat corrections
Enforce tone, voice, and formatting standards
Catch issues earlier in the publishing process
Improve consistency across contributors
Style Guide Suggestions include a default prompt. Customers who want guidance tailored to their own style guide can customize the prompt to reflect their newsroom standards.
Suggested Content (Powered by Vector Powered Search): Surface the right related content — intelligently.Through vector search, the AI Assistant analyzes story context and recommends:
Related items
Featured media
These suggestions help strengthen story depth, improve engagement, and support internal linking strategies — all without requiring authors to manually search for assets. Vector search–powered recommendations are available to customers provisioned on the Advanced AI package.
What to Expect with AI Assistant General Availability
Any customer leveraging Arc Intelligence will have access to the AI Assistant in Composer
Respects existing Arc Intelligence permissions
Any user with the AI Editor permission will be able to use the native AI Assistant experience
Available features reflect Arc Intelligence package
New settings will be default to only run AI Assistant workflows manually
This means users with access will see the AI Assistant in Composer, but no automatic updates will run unless enabled by an administrator in Global Settings.
Customers can roll out automated suggestions and updates as they see fit
Customers can update AI Assistant settings at any time in Global settings
AI Assistant workflows are hooked up to Arc Prompts and will work with how you’ve configured prompts today
Style Guide suggestions will have a default prompt that needs to be updated if customers want suggestions based on their own style guide
Additionally in Composer 2.9 we addressed the following issues:
Comments now save drafts automatically if there is content written

Release summary
Arc Subscriptions now supports Paypal Multiparty Payment Solutions as a platform-supported payment gateway option (ID: 23).
Paypal’s “platform and marketplace payment solutions enable you to onboard global sellers by applying local regulations and compliance rules.”
Key features include:
Accepting multiple payment methods
Customizing pricing with partner fees
Handling foreign exchange for global currencies
Making payouts
Managing disputes and chargebacks
Your organization must have a PayPal Premier or Business account. It is not possible to set up this gateway using a personal PayPal account.
Only PayPal account–to–account transactions are supported.This feature does not function as a traditional credit card gateway.
Although PayPal accounts may be funded by linked bank accounts or credit cards, those funding sources are managed entirely within PayPal and are not visible or configurable in this system.Free trials are not supported. Subscriptions cannot be initiated with a trial period when using PayPal MultiParty.
Payment method changes are limited:
Users can switch from PayPal to another payment method.
Users cannot switch from another payment method to PayPal.
Subscribers using PayPal MultiParty can update their preferred card or funding source directly within the PayPal interface.
Get All Subscriptions endpoints updated
The Get All Subscriptions endpoints, included undocumented constraints and inconsistent behavior. This release streamlines the experience and includes explicit guardrails.
GET /sales/public/v1/subscription/all will return up to 25 subscriptions
GET /sales/public/v1/subscription/allactive will return up to 15 subscriptions
A new API (GET /sales/public/v1/subscription/gifted) was added that will return up to 250 gifted subscriptions
Notice: the next release of Arc Subscriptions (version 1.104) will include the following changes:
Gifted subscriptions will be removed from get-all-subscriptions and get-all-subscriptions will return up to 100 subscriptions
Gifted subscriptions will be removed from get-all-active-subscriptions and get-all-active-subscriptions will return up to 50 subscriptions
Enhanced Smart Dunning IFX Events
We’ve improved Smart Dunning support for the IFX payment gateways to better handle payment declines.
Decline type is not supported, so your custom code can now distinguish between soft and hard declines. Previously, all declines were treated as soft.
The legacy response type will still be accepted, but messages in this format
are now also allowed for declines. In the above example insufficient funds will eventually appear in the Smart Dunning console where it can be designated as hard or soft.

Release summary
The AI Assistant has officially arrived in Composer — bringing intelligent, real-time editorial support directly into the publishing workflow. Designed to work alongside authors, the AI Assistant helps newsroom teams move faster, publish smarter, and maintain consistent standards — all without disrupting how they work today. From metadata optimization to style guidance and content enhancements, it acts as an integrated publishing partner embedded exactly where content gets created.For Arc Intelligence customers, this unlocks a more streamlined, standards-driven publishing experience — with flexibility and control built in from day one.
What the AI Assistant delivers
The AI Assistant is built around three core editorial workflows designed to improve quality, consistency, and performance directly inside Composer.
Metadata Review: Ensures every story is optimized before it’s published.
Supports: Headlines, Tags, SEO keywords, Descriptions
Admins can choose whether metadata updates are automatically applied or surfaced as suggestions for review.
All AI-generated changes are clearly labeled, with visual indicators to ensure transparency and control.
Style Guide Suggestions: The AI Assistant provides real-time editorial and stylistic recommendations aligned to your organization’s standards — helping authors meet expectations before stories move into review.
Reduce repeat corrections
Enforce tone, voice, and formatting standards
Catch issues earlier in the publishing process
Improve consistency across contributors
Style Guide Suggestions include a default prompt. Customers who want guidance tailored to their own style guide can customize the prompt to reflect their newsroom standards.
Suggested Content (Powered by Vector Powered Search): Surface the right related content — intelligently.Through vector search, the AI Assistant analyzes story context and recommends:
Related items
Featured media
These suggestions help strengthen story depth, improve engagement, and support internal linking strategies — all without requiring authors to manually search for assets. Vector search–powered recommendations are available to customers provisioned on the Advanced AI package.
What to Expect with AI Assistant General Availability
Any customer leveraging Arc Intelligence will have access to the AI Assistant in Composer
Respects existing Arc Intelligence permissions
Any user with the AI Editor permission will be able to use the native AI Assistant experience
Available features reflect Arc Intelligence package
New settings will be default to only run AI Assistant workflows manually

Customers can roll out automated suggestions and updates as they see fit
Customers can update AI Assistant settings at any time in Global settings
AI Assistant workflows are hooked up to Arc Prompts and will work with how you’ve configured prompts today
Style Guide suggestions will have a default prompt that needs to be updated if customers want suggestions based on their own style guide
Additionally in Composer 2.9 we addressed the following issues:
Comments now save drafts automatically if there is content written
Further pasting improvements have been made when copy and pasting from Word docs including white space issues
Divider lines in some templates no longer cause intermittent errors
A fix to single quotes in different languages that caused unintentionally duplication has been resolved

The Collections API currently defaults to returning 20 items per request but allows developers to specify a higher limit. To maintain the stability and performance of our platform, we are introducing a maximum limit of 100 items per request.
New Limit: The API will now cap all requests at 100 items maximum.
Query Adjustment: Any request specifying a limit greater than 100 will automatically be rewritten to limit=100. As a result, your results may be truncated.
Upcoming enforcement
On March 31, 2026, we will reject all requests that specify a limit above 100. Clients should update their integrations accordingly to ensure uninterrupted access.
How to Retrieve All Collections
If you need to fetch more than 100 items, use pagination to iterate through your collections.
Action required
Update any fetches to the Collections API that request more than 100 items.
