Community code lists include Update2.5 with scrolls, books and accessory tickets. That is evidence of a published reward report, not proof that those systems were introduced by the same patch.
The reported bundle
The sources list three Engraving Scrolls, five Enchant Books and five Accessory Tickets. Current redemption has not been tested. Check the code page for the full status explanation before using the code.
Do not infer a release history
A code named after a version does not establish a launch date, balance change or new mechanic. This collection does not contain the original complete developer changelog for 2.5, so no such list is presented.
