It is not yet on main branch! You'll need to right click on the game -> Properties -> Game Versions & Betas and set it to testing. Let me know how stable it is, if multiplayer works well, if mods work etc.
Full changelog:
Performance with a big show loaded is improved by about 2x (25fps to 50fps)
Performance with a lot of fireworks spawned is also improved
Mods now load instantly in menu and on demand during game when needed. (First startup might take a while to optimize them)
Firing system has now a "spread" parameter - if you connect for example a few mortars to a module and set spread to 0.25, the mortars will fire with a 0.25s delay between each other
Firing system controller now has a music waveform
Firing system controller now synchronizes music with all the players
Now if you middle click on a mortar rack while adding fireworks to a firing system module it'll add every mortar from that mortar rack to that module
Added shortcut to clean the world if you hold DEL key for about a second
Added ability to remove fireworks that were already fired in server settings menu (T)
Added separate volume slider for music from firing system controller
Mass explosions now sound better (try it :))
Blown up cakes now have a chance to do some fun things... try it!
Added a preview of spawned fireworks when selecting things in the spawn menu
Shells can now be inserted quickly inside mortar racks if there are already mortars in it
Loading save files is WAY faster
Saving should be way faster too!
Added really cool splashes to water! Be aware, the cooler ones are only available in high & explosive graphics quality. Try it out with a big cracker :)
Player movement in water has been improved
Most particles now bounce off the ground!
The game now takes about 2x less memory (about 4GB, 6-7GB with a big show loaded)
Stability of the game has been overall improved
A lot of bugs have been fixed
A lot of other small changes!
It is not yet fully stable, let know of bugs, feedback etc. on the Discord #chatting-pyroworks channel!
