- Update to version 2.2.1
* Shadows have been added to the game.
* A slew of camera options originally known as the “ficklecam”
mod (Made by fickle) from the forums has now been added to the
game.
* Added the “Simple” play style, which automatically orientates
the camera. It may prove easier for players using controllers.
* OpenGL batch files are included in this package.
* GIFs may be recorded under OpenGL.
* The renderer may now be changed while in game.
* Players now only uncurl from a ball after hitting the ground
when using the Elemental Shield’s ability. This means you can
break those monitors under the goop in THZ2!
* Added sixteen angle sprite support.
* Fixed the Fire Shield being extinguished by lava.
* Adjusted Tails’ flight to discourage mashing the jump button.
* Players no longer slide off polyobjects

- Update to version 2.1.24
* APNG recording should now work in the Linux/Mac versions.
* Added the “banip” command, for banning people by IP.
* Editing enchancements for music: song length, positioning, and
fading features with Linedef Exec and Lua support
* Fixed dedicated servers timing out after the credits.
* OpenGL: Sprite billboarding can be enabled with the
“gr_spritebillboarding” console variable. This just means they’ll
always face the camera rather than looking flat as paper.
* “localhost” now works as a valid IP address to join again, after
being broken since version 2.0. This means people can now join
their own servers without needing to find out their local IP anymore.
