Recently Bitbucket have updated their Repository settings with direct support for Webhooks, and will be removing support for their old Services features in the future.
In Deploy we have now implemented support for the Webhooks and while you won't need to make any changes to your projects or their settings in Deploy, you will need to update your Bitbucket repositories to reflect this. For more information on adding or updating Webhooks to Bitbucket, see our support article.
As always, don't hesitate to drop us an email to with any questions.
