Branch	Build failing 🚨
Dependency	abstract-leveldown
Current Version	2.6.2
Type	dependency

This version is covered by your current version range and after updating it in your project the build failed.

abstract-leveldown is a direct dependency of this project this is very likely breaking your project right now. If other packages depend on you it’s very likely also breaking them.
I recommend you give this issue a very high priority. I’m sure you can resolve this 💪
