  • API support for checkbox groups, allowing senders to define multi-select options within a form - Checkbox groups let senders specify how many options recipients must select, bringing new flexibility for agreements that require structured multi-choice input.
    Note that the option for multi-select checkboxes is available for API created agreements only. 
    • Define multi-select checkbox groups.
    • Configure rules for exact, minimum, maximum, or ranged selections.
    • Validation is enforced during signing in the classic eSign experience.

  • User Invitation to their Acrobat Sign organization - Invite teammates directly from the Acrobat Sign interface with admin-controlled workflows for faster team adoption. Depending on configuration, invited users may be auto-provisioned, routed through Just-In-Time (JIT) provisioning, or require admin approval. This streamlined flow reduces friction for SMB and mid-market teams, accelerates adoption of shared workflows, and gives admins better visibility into real license demand.
    • New Invite button on Home and Manage pages for end users
    • Invited users receive a welcome email and are added seamlessly to the organization
    • Invitations respect existing auto-provisioning rules
    • Admins can review pending requests in the Access requests section
    • If auto-provisioning is disabled, requests are routed to admins for approval

Available environments: Commercial | Available tiers of service: Acrobat Sign Solutions VIP licensed only | Configuration scope: Account

  • Reorganized Users page - The Users page has been reorganized to better manage users in their various states, and to provide better visibility for newly invited teammates. This helps isolate users who are having trouble activating their accounts and accelerates onboarding for the larger team.

  • Allowed IP ranges for access to Acrobat Sign have been extended to Groups and APIs - More flexibility has been provided for IP restriction controls when securing access to Acrobat Sign. IP restrictions can now be configured at the group level by Group Admins. In addition, restrictions now apply to API access: if an account or group specifies an allowed set of IP addresses, both the Acrobat Sign UI and APIs can only be accessed from those addresses.
    • IP restrictions now apply to both UI and API access.
    • Group Admins can configure IP restrictions for their groups.
    • Users in multiple groups are evaluated against their default group’s IP policy.
    • Integrations and partner applications are allowed by default and not restricted by IP blocking. 
      • Admins can work with Adobe Support to block applications at the group or account level. If access is blocked, the application must use allowlisted IP addresses to connect to Acrobat Sign.

  • Remove Certification and Locking Signatures from Digitally Signed Agreements - Organizations that need to pass third-party signature validation services can now request Adobe support to configure their account or group settings to skip the application of Adobe’s Certificate and prevent locking signatures on digitally signed agreements. When enabled, agreements only contain the recipient's digital signatures, reducing rejection rates in strict regional validation tools.
    • Account admins can request Adobe support to exclude Adobe Certification and Locking signatures at the account and/or group levels.
    • Agreements contain only recipient digital signatures, improving acceptance by third-party validators.
    • Audit Report records when certification is skipped, including a SHA-256 document fingerprint
    • Applies across all export touchpoints: email attachments, Manage page downloads, API, and webhook payloads
    • Resolves compliance gaps raised by customers requiring validation under regional trust schemes- Description

  • PDF/A improved to support PDF/A-3B conformance and convert all uploaded files to the selected PDF/A standard - Admins can now enable conversion and normalization of uploaded files—including PDFs, Microsoft Office formats, and raster images—into PDF/A-2b or PDF/A-3b. Existing PDF/A files are validated, repaired if needed, or normalized to the configured target level.
    • Admins can configure PDF/A workflows at the account or group level.

  • "Authentication Method Updated" events in Audit Reports - Changes to recipient authentication methods can now be included in the Audit Report as discrete events. When a sender (or authorized delegate) updates a recipient’s authentication method—such as switching from SMS OTP to Email OTP—the update is captured and recorded in the agreement’s audit report, activity log, and API events list.
    • A new event, Authentication Method Updated, appears in the audit report, showing:
      • The recipient impacted
      • The user who made the change
      • The original authentication method
      • The new authentication method
      • The timestamp of the change
    • Events are also exposed through the GET /agreements/{agreementId}/events API.
    • Activity logs display the event with recipient, initiator, and timestamp details.

Resolved Issues

Issue Description
4505635 Summary: The agreement_retention scope is unavailable in the GovCloud API.
Fix: The scope has been configured to work in the GovCloud environment with the Okta integration.
4515686 Summary: Webform owners cannot replace the counter signer on existing webforms in specific validation circumstances. Attempting to update the counter signer email returns an error: "You cannot add or remove your email address in the current state of the agreement." 
Fix: The validation is updated so that the correct sender or countersigner email is recognized. Webform owners can now replace the countersigner as expected. Users do not need to take any action.
4519727 Summary: The modern format for phone numbers in Benin isn't recognized (10 character length)
Fix: Acrobat Sign now supports the new 10-digit phone number format for Benin. Users can enter valid numbers with the +229 country code without errors. No action is required from users.
4525532 Summary: Prefill role is not available by default in the New Authoring Experience
Fix: The Prefill role has been exposed by default in the recipient context list when composing agreements
4526142 Summary: When applying a form field layer from an existing template in the new authoring experience, some fields do not copy over. 
Fix: New checking has been added to ensure the complete template is transferred.
4527772 Summary: Agreements with sequential routing sometimes lose the recipient name field when assigned to a participant with the Form Filler role. The field fails to display for that recipient, leaving the agreement incomplete.
Fix: Significant updates to the REST API have been established to ensure all fields are retained.
4527945 Summary:  Use of a form field template in an agreement that has a recipient group doesn't work - the template validation code filters out the recipient group participant and the associated fields are lost.
Fix: Code has been reworked to use a different member parameter instead of the email value.
4528619 Summary: When editing a recipient group name in the new Send experience, the cursor automatically jumps to the end of the text after each change. This makes it difficult to edit the name in one go. 
Fix: : Request tracking is updated to ensure all authentication methods load properly before sending. Agreements now process correctly once all required authentication details are provided. No action is required from users.
4531835 /
4537898/
4541002
Summary: Customers encounter errors when using some third-party certificates because the updated root certificates are not trusted, causing issues with webhooks and notifications.
Fix: Root CAs are being updated.
4532798 Summary: When applying a form field layer, Acrobat Sign creates a new document to capture the layer information. Due to versioning issues in these new documents, some “modify agreement” workflows fail.
Fix:  We have shifted our approach from pulling the source information through an API to publishing an event when a form field layer template is applied and consuming it in order to populate the source information for the agreements.
4534813 Summary:  Users in multiple groups cannot use automatic field recognition when creating templates or agreements. 
Fix: Added a new test to verify field detection in authoring V5 for a user with many groups.
4535639 Summary: In some agreements, required image fields are missing from the signed PDF. Although the FormFields.csv shows image URLs, the images do not appear in the final agreement.
Fix: The order of a few functions was changed to ensure that inline image fields are processed regardless of whether the form is present, and now the images show up properly for all signers.
4535828 Summary: The hyperlinks in the documents are getting changed when the agreement is sent.
Fix: When the URL is already encoded specifically with: /, which is a reserved character for URLs, decodeURI is not decoding them, so I changed it to decodeURIComponent to verify the condition before encoding.
4536354 Summary: Large PDF documents (~150 pages) fail to load with "unsupported format or password protected" error due to insufficient frontend timeout for image availability checks.
Fix: Increase max_retries parameter from 7 (default) to 13, extending the timeout from ~30s to ~60s. This provides sufficient time for large document processing.
4538897 Summary: Original IText templates with rotated page content cause the flattened signatures to be rotated out of place on the page.
Fix: Before flattening the signatures into the page content, the page content is wrapped with a push/pop gstate to keep the rotational matrix from affecting the added signatures.
4539304 Summary: Swagger documentation is default to "Try it out" mode and API consumers find it difficult to browse request schema
Fix: The documentation now defaults to view mode instead of “Try it out,” so schemas are visible by default. Performance is improved by eliminating redundant API calls for primitive data types.
4542576 Summary: Webhook payloads for the AGREEMENT_ACTION_COMPLETED event return different participant status values in the 16.2 Sandbox release. Previously, memberInfos entries showed “ACTIVE” or “REPLACED” even after signing. In 16.2, they show “COMPLETED.” when Dynamic Participation isn't enabled.
Fix: Use of new participant statuses will only be used if Dynamic Participations Feature for In-Flight Agreements is enabled.
