Super Smash Flash 2 Demo

The Super Smash Flash 2 Demo is made up of a series of playable alpha/beta versions of the game. These demos are released usually after a sizable amount of new content is added to the game in order to test everything coded within the game and keep fans interested. New versions of the demo usually include several new features, characters, or stages, and many bug fixes. The current and final version of the demo is Super Smash Flash 2 Beta, released on May 29, 2017, and its current revision is 1.0.2 beta.

Developer demo
There is a test demo for exclusive use by SSF2 developers and SSF2 balancers called the developer demo, or devmo for short. Its main function is to test new content before its public release (and thus preventing bugs from being in the release). Because of its exclusivity, Devs usually enjoy mocking non-devs in the McLeodGaming Forums by showing them screenshots from the devmo. The devmo includes a peculiar fps counter, which is not available for the public version.

Trivia

 * Although Super Smash Flash 2 has been in development since 2007, the developers feel that the game did not truly enter development until 2010 with the release of v0.6.
 * Demos v0.9a, v0.9b and Beta were first shown at Apex 2013, 2014 and 2015, respectively, making it the three consecutive years that SSF2 was showcased at Apex. As Apex 2016 was pushed back to the summer, entering in conflict with the developers schedules, it was decided to wait until Super Smash Con 2016 instead.
 * Beta has been showcased twice at Super Smash Con, in 2015 and 2016. This makes Beta the most showcased demo version of the game at tournament events.
 * Almost everything that was added to 0.9b were fan-suggested changes to the game, which made the game's popularity increase at a faster rate than before.
 * Beta marked the longest gap between two major versions of the game thus far, with 34 months since the release of 0.9b.
