v1.5.0

Minor Changes

• #251 8ce7b8d Thanks @DjimoSerodio! - Add optional attachment tags using the same strong-reference classifications and logical AND semantics as collections and features.

• #258 4baf102 Thanks @holkexyz! - Add optional validFrom and validUntil to app.certified.badge.award, so an award can state when it starts and stops applying: a certification granted before it was recorded, or a verification that lapses. Names follow W3C Verifiable Credentials 2.0 and Open Badges 3.0. Expiry is distinct from revocation, which remains deleting the award record.

• #258 5e72f78 Thanks @holkexyz! - Add legalName, logo, publicEmail, and additionalLocations to app.certified.actor.organization, so partner directories can publish an enterprise's registered name, full logo (wordmark or combination mark), public contact email, and every location it operates from. All four are optional, so existing records stay valid.

  Clarify field descriptions to say where each piece of organization data belongs: the square brandmark goes in app.certified.actor.profile avatar and the full logo in organization.logo; the public-facing name in profile.displayName and the legal name in organization.legalName; the main website in profile.website rather than urls; and the primary location in location (the one point shown on a map), with further locations in additionalLocations. The location description now notes that a strong reference pins a version, so it must be updated when the location record is edited.
