What happened to your addons in Minecraft full version 1.21.90

The Chase the Skies update in Minecraft 1.21.90 introduced new features but broke many addons, requiring adaptations to the changes and new visual possibilities.
Good News
The Chase the Skies Minecraft update just dropped, including very promising new Vibrant Visuals features and improvements, along with a few neat optimizations.
Bad News
This huge life-changing update broke my addons in various ways:
- The update patches my invisibility method used for making spawn cancels unnoticeable, causing pink entities to be visible all over the place.
- The update also changed a few coding-related things, mainly in behavior packs, as well as some strict syntax and suffix rules I will have to adapt to.
Vibrant Visuals
Vibrant Visuals brings very promising yet powerful new possibilities for addons and Minecraft in general, but at the cost of quite a lot of effort adapting to the new learning curve. MER Textures, for instance, are a totally new different world!
Future Plans
I will be very busy making my addons compatible with these changes. However, I can't fully promise these updates to be playable soon mainly due to IRL stuff and routines. I'm still very dedicated to making very cool addons, but I couldn't guarantee those work in this Minecraft drop yet, unfortunately. The majority of them broke. :(
Any successful updates/patches will be announced here on Modbay or on YouTube as soon as they become available! Thanks for your patience! Cheers! ;)
