Due to the smaller scale of Beta 1.2.5, a final bonus update was set to be released on December 20 with no early release for McLeodGaming Insiders. This update was revealed to be Beta 1.3, as the developers felt they had added enough new content since the release of Beta 1.2 to warrant incrementing it.
· Ganondorf as a new character · Butter Building as a new stage, and a resprite for Fourside · Character-specific Target Smash stages for certain characters, with more to be added over time · Improved replay system with the ability to adjust speed and frame step, auto-save after matches, and save Stadium replays
Notably, the auto-updater was removed from the installer version of the game, with update notices instead being handled by the News Feed.
