 # julia-invalidations
-Uses [`SnoopCompile.@snoopr`](https://timholy.github.io/SnoopCompile.jl/v2/snoopr/)
+Uses [`SnoopCompile.@snoop_invalidations`](https://timholy.github.io/SnoopCompile.jl/dev/tutorials/invalidations/)
 to evaluate number of invalidations caused by `using Package` or a provided script.
 
-Currently this action uses SnoopCompile v2.
-In a future release, we will upgrade to SnoopCompile v3.

 ## Usage
 
 This is a composite github action, that can be inserted into a github action on the target repo to evaluate number of invalidations
