See here for an (non necessarily efficient) idea for reproducible random number independent on number of threads the code run with, version of Julia and specific RNG:

[https://sylvaticus.github.io/BetaML.jl/stable/Utils.html#BetaML.Utils.generateParallelRngs-Tuple{Random.AbstractRNG,%20Integer}](https://sylvaticus.github.io/BetaML.jl/stable/Utils.html#BetaML.Utils.generateParallelRngs-Tuple%7BRandom.AbstractRNG,%20Integer%7D)

```julia
TESTRNG = StableRNG(123)

# ==================================
# New test
println("** Testing generateParallelRngs()...")
x = rand(copy(TESTRNG),100)

function innerFunction(bootstrappedx; rng=Random.GLOBAL_RNG)
     sum(bootstrappedx .* rand(rng) ./ 0.5)
end
function outerFunction(x;rng = Random.GLOBAL_RNG)
    masterSeed = rand(rng,100:9999999999999) # important: with some RNG it is important to do this before the generateParallelRngs to guarantee independance from number of threads
    rngs = generateParallelRngs(rng,Threads.nthreads()) # make new copy instances
    results = Array{Float64,1}(undef,30)
    Threads.@threads for i in 1:30
        tsrng = rngs[Threads.threadid()] # Thread safe random number generator: one RNG per thread
        Random.seed!(tsrng,masterSeed+i*10) # But the seeding depends on the i of the loop not the thread: we get same results indipendently of the number of threads
        toSample = rand(tsrng, 1:100,100)
        bootstrappedx = x[toSample]
        innerResult = innerFunction(bootstrappedx, rng=tsrng)
        results[i] = innerResult
    end
    overallResult = mean(results)
    return overallResult
end

# Different sequences..
@test outerFunction(x) != outerFunction(x)

# Different values, but same sequence
mainRng = copy(TESTRNG)
a = outerFunction(x, rng=mainRng)
b = outerFunction(x, rng=mainRng)

mainRng = copy(TESTRNG)
A = outerFunction(x, rng=mainRng)
B = outerFunction(x, rng=mainRng)

@test a != b && a == A && b == B

# Same value at each call
a = outerFunction(x,rng=copy(TESTRNG))
b = outerFunction(x,rng=copy(TESTRNG))
@test a == b

```

I thought that the 1.8.0-dev changes are in News file, and that what is new for 1.7.0 are on History. I think It’s as you say untill the beta-release. Then, everything in News have been moved to History. Now History points to 1.8.0-dev. Maybe I’m wrong. Sorry if that’s the case.

UPDATE: Sorry, I was pointing to `master` branch on which what’s on NEWS.md is now on HISTORY.md.
