TL;DR
Massive update with many new features. I also released a draft of our new thread but it's far from done.

Opening Themes
• Themes re-imagine the opening experience
• By default, styles are locked and you may
unlock them by spending dust
• You may force some boxes to have the same
opening theme regardless of what players
have currently selected
• You may unlock an opening theme - players
can select it regardless if they have it
unlocked or locked.
• For now, only the Christmas opening theme
is available to purchase - a new theme will
be released in the future updates

Mystery Boxes
• You may define loot chances in the box configs (loot_id;loot_chance)
Loot chances inside the box configs are prioritized
• Added Christmas Box as a pre-generated box
• Common Box uses the Standard opening theme
• Christmas Box uses the Christmas Special opening theme

Mystery Loots
• Messages, broadcasts, commands, sounds, and fireworks
have their own individual settings discovering and duplicate
• Fixed sounds and fireworks not taking into account
whether the loot is a discovery or a duplicate
• You may disable duplicate loots entirely or for certain players
• You may use decimals as loot chances (e.g. 10.5%)
• Loot chances inside the loot configs are still
supported but not prioritized (see above)

Mystery Vaults
• Boxes have been moved into a different menu
• Vault manager item is only shown to OPs
• There was a bug causing the edit mode
to fail and has been successfully fixed
• We are still working on optimizing the particles
around the vault - more info will be revealed soon
