Description

Discourse is an open-source discussion platform. From versions 2026.1.0-latest to before 2026.1.4, 2026.3.0-latest to before 2026.3.1, and 2026.4.0-latest to before 2026.4.1, GroupPostSerializer declared include_user_long_name? as the predicate for its :name attribute, but AMS looks for include_name?. The misnamed predicate was never called, so object.user.name was always serialized regardless of SiteSetting.enable_names. This issue has been patched in versions 2026.1.4, 2026.3.1, 2026.4.1, and 2026.5.0-latest.1.

Affected configurations

• discourse discourse (< 2026.1.0) • discourse discourse (>= 2026.1.0 < 2026.1.4) • discourse discourse (>= 2026.3.0 < 2026.3.1) • discourse discourse (>= 2026.4.0 < 2026.4.1) • discourse discourse 2026.5.0
