Previous state

The Bitbucket Cloud diff and diffstat APIs continued to support the deprecated ?merge=true query parameter while Atlassian's earlier deprecation notice remained pending.

Current state

Atlassian says the diff and diffstat APIs will no longer support the ?merge=true query parameter from 4 September 2026.

Who needs to care

Bitbucket Cloud integrations that request merge-oriented diff or diffstat behaviour through the ?merge=true query parameter.

What to do

Remove use of ?merge=true before 4 September 2026 and adopt Atlassian's supported alternative for retrieving merge-conflict information where that capability is required.

What the source does not prove

Atlassian proves removal of the ?merge=true parameter capability on the diff and diffstat APIs. It does not retire the diff or diffstat endpoints themselves or Bitbucket Cloud generally.
