Deprecation Notice Brownout Notice: OAuth 1.0 and Implicit Grant Flows for Bitbucket Cloud

REST API - Bitbucket Cloud

As shared in our https://developer.atlassian.com/cloud/bitbucket/changelog/#CHANGE-2887, Bitbucket Cloud will fully deprecate support for OAuth 1.0 and implicit grant flows on Feb 27, 2026. To help teams identify and migrate any remaining usage ahead of the enforcement date, we will run a series of controlled brownouts starting Feb 28, 2026, for two weeks, after which the functionality will be fully removed on Mar 14, 2026.

During each brownout window:

  • All requests to generate OAuth 1.0 or implicit grant access tokens will fail with an HTTP 400 error code.

  • All requests authenticated with existing OAuth 1.0 or implicit grant access tokens will fail with an HTTP 401 error code.

Announcement Community Licenses Renamed to Social Impact Licenses

Marketplace Platform

Effective date: 25 Feb 2026 (PT)

1. Naming update

  • “Community Licenses” pricing plans are now called “Social Impact Licenses.”

  • Social Impact customers are eligible nonprofit and social enterprise customers approved for Atlassian Social Impact (formerly Community) Licenses.

  • The new discounts are designed to remove cost as a barrier to adopting collaboration tools—including Marketplace apps—so social impact teams can focus on delivering their mission.

  • For detailed information on:

    • the new Social Impact and Social Impact – Global Access license types

    • discount levels and eligibility

    • expected impact on Marketplace Partners

    please see the Quick Reference Guide:
    https://atlassianpartners.atlassian.net/wiki/spaces/resources/pages/1330544651/Changes+to+Community+Licenses+-+Quick+Reference+Guide


2. Renewals & new applications

From 25 Feb 2026 (PT):

  • Existing Social Impact customers

    • Automatically receive the new discounts at their next renewal (no action required from partners).


3. What do Marketplace Partners need to do?

From 25 Feb 2026 (PT), the license_type field in the Transactions API and Licenses API will return:

  • SOCIAL_IMPACT

  • SOCIAL_IMPACT_GLOBAL_ACCESS

instead of the previous COMMUNITY license_type value.

Exception: COMMUNITY Licenses in the new billing system(check here to identify licenses from New Billing system here) will be updated to the new license_type post next renewal.


Action for partners:

  • Update any logic, reporting, or internal tooling that:

    • filters or segments customers by license_type

  • Ensure your systems recognize SOCIAL_IMPACT and SOCIAL_IMPACT_GLOBAL_ACCESS as new license_type.

Deprecation Notice Removal of Public REST APIs to retrieve various Bitbucket artifacts for a user

REST API - Bitbucket Cloud

As shared in our previous announcement, Bitbucket Cloud will fully sunset the cross-workspace APIs on March 31, 2026. We had previously communicated an earlier date but have decided to postpone this due to feedback from our partners.

Based on feedback, we have also released a new API that allows you to list repository permissions in a workspace for a user.

To help teams identify and migrate any remaining usage ahead of the enforcement date, we will run a series of controlled brownouts starting March 23, 2026, for one week. During each brownout window, requests using the old cross-workspace APIs will be rejected, and affected endpoints will return a 404 Not Found error. If you have made the switch to the new APIs, announced here, then you will not be impacted during the brownouts.

Final removal

 

During the brownout, if you encounter an error, please contact your app vendor. They will need to switch to using the new, support cross-workspace APIs.

After the brownout schedule completes, requests to the old cross-workspace APIs will stop working entirely at all time will no longer be supported starting March 31, 2026.

We understand these changes require effort, and we're here to support you. If you have questions, need migration guidance, or run into issues, please contact Atlassian Support.

Announcement New Data Center app submissions no longer accepted On Marketplace

Added Now supporting advanced conditional logic in Forms API

REST API - Forms

We have added advanced conditional logic in the Forms API responses. The ‘save form template’ now accepts requests with advanced conditional logic.

More details

When a section has advanced conditional logic, the form response will include two new properties in the form condition input object design.conditions.CONDITION_ID.i:

  • operator - the logic operator between check groups, OR or AND.

  • groups - the list of check groups. In each check group:

    • operator - the logic operator between checks in the group, OR or AND.

    • checks - the list of checks in the check group. In each check:

      • fieldId - the question ID which the check depends on.

      • type - the comparison type, SOME_OF, NONE_OF or ALL_OF.

      • constraint - the list of constraint values the check depends on.

The form condition output object’s condition type design.conditions.CONDITION_ID.o.t now supports two types:

  • sh - show

  • hide - hide

Example:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 { "design": { "conditions": { "15": { "i": { "operator": "OR", "groups": [ { "operator": "AND", "checks": [ { "fieldId": "12", "type": "SOME_OF", "constraint": ["1", "0"] } ] } ] }, "o": { "sIds": ["3"], "t": "hide" } } } } }

More details

2026 updates to Cloud App Security Requirements

Key additions to the general Cloud App Security Requirements include:

  • AI Security: New requirements for apps using Forge Rovo actions and agents, including validating action inputs as untrusted, implementing permission checks for admin-level actions, and accurately configuring actionVerb values.

  • Data Protection:

    • External OAuth2 clients must use Forge's OAuth2 Providers and be configured as confidential clients where supported.

    • Application logs must strictly exclude PII, credentials, and sensitive data.

    • Apps must ensure strict tenant isolation during runtime.

    • Apps must not execute arbitrary code by spawning child processes (e.g., using Node.js child_process).

  • Application Security:

    • Apps using Forge SQL must use parameterized queries to mitigate SQL injection risks.

    • Updated guidance on Content Security Policy (CSP) regarding unsafe-inline and unsafe-eval directives.

  • Runtime Security:

    • Apps must not use EOL (end-of-life) Node.js runtimes.

Deprecation Notice Deprecating Connect Inspector Service

Connect - Core Platform (excludes product REST APIs)
Connect - Jira Cloud Platform (excludes Jira REST APIs)
Connect - JSM Cloud (excludes JSM REST APIs)
Connect - Jira Software Cloud (excludes JSW REST APIs)
Connect - Confluence Cloud (excludes Confluence REST APIs)
Connect - Bitbucket (excludes Bitbucket REST APIs)

The Connect Inspector service is moving to open source and also being deprecated. This service will no longer allow the creation of new temporary apps. Already registered temporary apps will stop recording new events, and old events will be deleted. Any apps already installed on developer sites will not be uninstalled.

More details

Why is this deprecation necessary?

Connect Inspector helped developers better understand Atlassian Connect lifecycle events and web-triggers. This service allowed developers to generate a temporary and unique Atlassian Connect app, which could be installed on a cloud development environment. This, in turn, let developers inspect the full request flow of a Connect app.

However, usage of the Connect Inspector has decreased significantly due to the following:

Deprecating Connect Inspector allows the team to focus on Forge.

Dates and rollout

The Connect Inspector service will be discontinued by the end of February 2026.

Migration guidance

Developers who still need similar functionality can use the open‑sourced version of the tool.

Atlassian Connect will reach end of support in December 2026. Migrate to Atlassian Forge for a more robust Events model.
