 ```julia
 julia> ]
-(v1.6) pkg> add FourierFlows
+(v1.10) pkg> add FourierFlows
 ```
 
 We recommend installing FourierFlows.jl with the built-in Julia package manager, because
 this installs a stable, tagged release. Later, you can update FourierFlows.jl to the
 latest tagged release again via the package manager by
 
 ```julia
-(v1.6) pkg> update FourierFlows
+(v1.10) pkg> update FourierFlows
 ```
 
 Note that some releases might induce breaking changes to certain modules. If after anything
 happens or your code stops working, please open an [issue](https://github.com/FourierFlows/FourierFlows.jl/issues) 
 or start a [discussion](https://github.com/FourierFlows/FourierFlows.jl/discussions). We're
 more than happy to help with getting your simulations up and running.
 
-!!! warn "Use Julia 1.6 or newer"
-    The latest FourierFlows.jl requires at least Julia v1.6 (the current long-term-release).
+!!! warn "Use Julia 1.10 or newer"
+    The latest FourierFlows.jl requires at least Julia v1.10 (the current long-term-release).
     Installing FourierFlows with an older version of Julia will install an older version
     of FourierFlows.jl (the latest version compatible with your version of Julia).
