I was wondering if there is an equivalent code for `Pkg.installed("PackageName")` or `Pkg.status("PackageName")` in Julia v1.0. I want to check the version of a package installed.

Enter the package repl mode with `]`, then

```julia
(v1.0) pkg> st

```

will show the contents of your current environment (i.e. a list of installed packages and their versions)

Anyway to do it for an individual package?

`Pkg.installed` is available on Julia v1.0 too

```julia
julia> using Pkg; Pkg.installed()
Dict{String,Union{Nothing, VersionNumber}} with 4 entries:
  "StaticArrays" => v"0.8.3"
  "Documenter" => v"0.19.6+"
  "Sandbox" => v"0.1.0"
  "BenchmarkTools" => v"0.4.1"

```

This works :

```julia
using Pkg

julia> a=Pkg.installed()
Dict{String,Union{Nothing, VersionNumber}} with 13 entries:
  "ReadStat" => v"0.4.1"
  "BenchmarkTools" => v"0.4.2"
  "Arpack" => v"0.3.1"
  "WinRPM" => v"0.4.2"
  "StatsBase" => v"0.32.0"
  "HDF5" => v"0.12.1"
  "IJulia" => v"1.19.0"
  "Plots" => v"0.26.2"
  "StatFiles" => v"0.8.0"
  "XLSX" => v"0.5.4"
  "DataFrames" => v"0.19.2"
  "OnlineStats" => v"0.27.0"
  "ApplicationBuilder" => v"0.4.0"

julia> "DataFrames" in keys(a)
true

```
