I installed Julia 1.0.3 (last stable release at time of writing this), but seems like SampledSignals does not work with this version. I thought about installing Julia 1.0.0, but can’t find an installable binary of it.

Any suggestions?

```julia
(v1.0) pkg> add SampledSignals

It looks like `SampledSignals` has a new version which support Julia 1.0, but that version hasn’t officially been released yet (it’s waiting on this: [https://github.com/JuliaLang/METADATA.jl/pull/19905](https://github.com/JuliaLang/METADATA.jl/pull/19905) to be merged).

Don’t worry about trying to install Julia 1.0.0: the set of available packages will always be the same for any 1.0.x version. Instead, you can just install the master branch of the package:

```julia
pkg> add SampledSignals#master

```

Awesome! Thanks for the fast reply. And good to know that this notation (#master) seems to bypass the version requirements
