August 2025 Developer Rollup

August brings a mix of UX polish and platform readiness for developers. You’ll see a new Sections Library modal in the page editor, upgrades to the marketplace listing editor, clearer certification renewal states, and the Smart Transfer tool rollout. We’re also postponing the Legacy CTA editor sunset while plans are finalized.

Sections Library modal improves “section-first” editing in the page editor

We’ve moved pre-built Sections, Embeds, and Saved Sections into a centered “Sections Library” modal, launched from a more prominent Add section button, so users can preview details before inserting. It’s already live for Landing Pages on the Elevate theme and is rolling out to Website Pages and remaining themes on September 12, 2025; for now, developers will see everything under a single Theme Sections category (custom categories aren’t yet exposed). Built-in search is being added now and broader rollout will continue once search ships, with future exploration into exposing categories and AI-assisted auto-tagging for developer sections.

App Marketplace Listing Editor Upgrade & Language Flexibility

We've upgraded our app marketplace listing editor to deliver a smoother, more efficient experience when creating or editing the listing for an app. This is primarily a backend improvement, though you will see some minor visual updates as well.

We're also removing the restriction that limited marketplace listing pages to only the languages officially supported by your app. Now, when creating or editing a listing, you can select any available language for your marketplace page, regardless of the settings for supported languages.

See the documentation for listing your app for more details.

App Certification Lifecycle Status & Renewal Update

We're introducing enhanced visual indicators for App Certification status in developer accounts, aligned with the new policy requiring certified apps to renew their certification every two years.

You will now see clearer, actionable status indicators throughout the certification lifecycle, including new states like “Expiring Soon” and “Under Review.” You can also view an app’s certification expiration date to better plan for recertification and avoid lapses in status. If a renewal is not submitted before the expiration date, the certification status and badge will be revoked.

In addition to the status indicators in your developer account, you will also receive automated reminder notifications when an app is close to expiration, beginning at 3 months before expiration, with a final reminder on the expiration date if no renewal has been submitted.

To prepare for certification or recertification, review your app’s compliance with HubSpot’s latest standards:

1. Certification requirements: Getting certified in the App Marketplace
2. Academy Course: Getting your app certified in the Marketplace

New Smart Transfer Tool (formerly CRM Migration)

Introducing an upgraded version of the CRM Migration Tool (formerly Smart Migration, now Smart Transfer), designed to enhance control, visibility, and ease during the migration of CRM data from third-party platforms into HubSpot. Previously, this tool was only available for Solution Partners and is now widely available to all HubSpot users.

What's changing?

• Enhanced Control and Visibility: Users have increased transparency and control during the data migration process.
• Data Audit and Cleanup: Easily audit, migrate, and clean up transferred CRM data to ensure accuracy and integrity.
• User-friendly Guidance: Includes comprehensive instructional videos from HubSpot Academy to streamline the migration process.

Users can find the Smart Transfer tool under Data Management > Data Integration. From there, clicking "Transfer data" opens the tool. Users can connect to a third-party app, resume previous transfers, and follow a guided process, including videos and setup wizards, to audit, configure, sync, and clean up CRM data through an integrated experience.

This update simplifies migration, giving users more control over data transfers. They can resume interrupted migrations, audit data at each step, and ensure data accuracy upon import. The user-friendly design and educational resources simplify migration, speeding up onboarding and increasing reliability.

Postponement of Legacy CTA Editor Sunset

We’re announcing a postponement of the previously communicated sunset for the Legacy CTA editor. This decision allows developers and teams additional time to continue using both the Legacy and new CTA editors while we finalize the transition plan.

For historical context on this specific sunset, please refer to:

• March 25, 2025 Developer Changelog – Original Sunset Timeline
• Community Forum Post– Sunset Scope and Timeline Discussion

What's changing?

• The planned sunset of the Legacy CTA editor is postponed. Previously, creation of new CTAs via the Legacy editor was to end on September 1, 2025, with a full transition by November 30, 2025. Those dates are no longer in effect. A new timeline will be announced in a future update.
• You can continue using the Legacy CTA editor to create and edit CTAs until further notice. There is no change to how existing Legacy CTAs behave — they will continue to function and capture analytics.
• The Legacy to 2.0 migration tool was removed in Q2 2024. Migration now requires recreating CTAs manually in the new editor.
• The new CTA editor now offers Smart CTAs (Live) and A/B testing (Public Beta).

What’s staying the same?

• Legacy CTAs continue to operate, track engagement, and can be edited using the Legacy editor.
• Both the Legacy and new CTA editors are available for use until a new sunset date is confirmed.

What does this mean for developers?

• No immediate migration is required — code and modules that rely on the Legacy editor or CTAs remain supported.
• Now is a good time to start testing the new editor, particularly for Smart CTAs and A/B variants.

Developers can continue to support both CTA types in custom modules, templates, and integrations with confidence that support is ongoing.

A new sunset date and transition plan will be communicated via the Developer Changelog.
