 Note: The [Turing](https://github.com/TuringLang/Turing.jl) probabilistic programming language uses this task copying feature in an efficient implementation of the [particle filtering](https://en.wikipedia.org/wiki/Particle_filter) sampling algorithm for arbitary order [Markov processes](https://en.wikipedia.org/wiki/Markov_model#Hidden_Markov_model).

-## For Developer
-
-### Release a new version
-    - If you have updates of the binary dylib (files under the `deps`
-      directory), you should:
-      - Update the version/commit information in [this
-        file](https://github.com/JuliaPackaging/Yggdrasil/blob/master/L/Libtask/build_tarballs.jl)
-        by a pull request
-      - Wait for that PR being merged, then you will find a new
-        release of the dylib
-        [here](https://github.com/JuliaBinaryWrappers/Libtask_jll.jl/releases)
-      - Then, in the root directory of the Yggdrasil project, run
-        `https://github.com/JuliaBinaryWrappers/Libtask_jll.jl/releases`,
-        you will get a build file like
-        `build/build_Libtask.v0.3.1.jl`. Copy the binary download
-        information (the variables `bin_prefix` and `download_info`)
-        from that generated file to `deps/build.jl` in our repo and
-        commit the changes.
-    - If you don't make any changes about the dylib, just ignore the
-      first step and go to next one.
-    - Update the new version number in `Project.toml`, ping
-      @JuliaRegistrator with `@JuliaRegistrator register` in a
-      comment.

+This feature is still experimental and should only be used with caution. Some discussions on its potential caveats can be found [here](https://github.com/JuliaLang/julia/pull/15078).
+
+## Julia nightly
+
+Libtask uses the `libtask_julia` library which is pre-built for Julia versions 1.3, 1.4, and 1.5 and
+distributed via the [Libtask_jll](https://github.com/JuliaBinaryWrappers/Libtask_jll.jl/) package.
+
+Julia nightly might not be compatible with the latest version of the `libtask_julia` library and is
+not officially supported. If you want to use Julia nightly, you have to add the Libtask_jll package
+manually:
+```julia
+julia> ] add https://github.com/JuliaBinaryWrappers/Libtask_jll.jl.git
+```
