At long last, the Julia developers are pleased to announce the release of Julia v1.3.0, the third minor release in the 1.x series. Binaries are available for all of your favorite platforms (Linux, Windows, macOS, and FreeBSD) at [Download Julia](https://julialang.org/downloads).

As a minor release, v1.3.0 contains no breaking changes, only new features, performance improvements, and marginal, undisruptive changes in behavior. The best reference for the changes in 1.3 is the [NEWS file](https://github.com/JuliaLang/julia/tree/v1.3.0/NEWS.md) for 1.3.0. There have also been a couple of blog posts highlighting some exciting new features in 1.3, including [multithreading](https://julialang.org/blog/2019/07/multithreading) and [Pkg artifacts](https://julialang.org/blog/2019/11/artifacts).

Note that 1.3, like 1.2 and 1.1 before it, does not have long term support. As of this release, 1.2 has been effectively superseded by 1.3, which means there will not likely be any further 1.2.x releases. Julia 1.0 is still currently the only long term support version.

We encourage everyone to give it a try. Packages can test with 1.3.0 on CI by specifying `1.3` on Travis, AppVeyor (with [Appveyor.jl](https://github.com/JuliaCI/Appveyor.jl)), and Cirrus (with [CirrusCI.jl](https://github.com/ararslan/CirrusCI.jl)). As always, let us know in the [issue tracker](https://github.com/JuliaLang/julia/issues) if you run into any issues.

Happy coding!

The bleeding edge branch `jl` in [julia-install (link to jl branch)](https://github.com/taqtiqa-mark/julia-install/tree/jl) should now build Julia 1.3.0:

```bash
$ sudo bin/julia-install julia 1.3.0

How can we transfer the list of installed packages in v1.2 into v1.3?

</div>

In your `~/.julia/environments` folder there’s a `v1.2` (or whatever version you are on) folder containing the `Project.toml` file, this is the list of installed packages (iirc the `Manifest.toml` includes installed dependencies, etc). You can copy/rename that folder to `v1.3` and in julia repl do `]instantiate`

There is no need to `instantiate`. All packages are already installed. It’s just the default environment that has changed.

Just to be sure (and not to alarm anyone; it’s probably nothing): my virus scanner tripped up a bit, as though it was treating the installer as suspicious. What can you tell me about it? It never happened before with previous Julia installations.

(I did verify the files.)

Thanks for the comment! Some package/dependencie may require specific julia versions so after a julia version update, the packages’ version may need to be changed, therefore it might be better to just copy over the `Project.toml` and use `]instantiate` to build the `Manifest.toml`? maybe `]up` should be enough…

If this is on Windows … uninstall your AV. I mean it. Windows Defender is as good (better) or bad as any other and far less intrusive.

I am going to celebrate by posting the

```julia
Note that if you want to keep the same packages as in 1.2 you 
can copy (or rename if you are no longer using julia 1.2)

How to get julia on the commandline to run julia-1.3 on a Mac

On a mac this is the easiest way

from [https://en.wikibooks.org/wiki/Introducing\_Julia/Getting\_started](https://en.wikibooks.org/wiki/Introducing_Julia/Getting_started)

A different approach is to create a link to the executable and put it into the `/usr/local/bin` directory (which should already be in your path), so that typing `julia` is the exact equivalent of typing `/Applications/Julia/.../julia` . This command does that:

```julia
ln -fs “/Applications/Julia-1.0.app/Contents/Resources/julia/bin/julia” /usr/local/bin/julia

```

replace “Julia-1.0” with the version of Julia you wish to run

COPIED FROM AN OLDER POST BELOW

Probably the easiest way is to issue a similar command like the one below in the MacOS terminal

```julia
ln -fs "/Applications/Julia-1.0.app/Contents/Resources/julia/bin/julia" /usr/local/bin/julia

```

Remember I said SIMILAR, you need to double check the location of julia first in the /Application folder

This is what I have on my Mac

```julia
$ cd /usr/local/bin
$ which julia
/usr/local/bin/julia
$ ls -l julia*
lrwxr-xr-x 1 ssiew admin 62 18 Nov 12:07 julia -> /Applications/Julia-1.3.app/Contents/Resources/julia/bin/julia
lrwxr-xr-x 1 ssiew admin 62 22 Sep 2018 julia06 -> /Applications/Julia-0.6.app/Contents/Resources/julia/bin/julia
lrwxr-xr-x 1 ssiew admin 62 22 Sep 2018 julia07 -> /Applications/Julia-0.7.app/Contents/Resources/julia/bin/julia
lrwxr-xr-x 1 ssiew admin 62 13 Apr 2019 julia10 -> /Applications/Julia-1.0.app/Contents/Resources/julia/bin/julia
lrwxr-xr-x 1 ssiew admin 62 23 Aug 18:41 julia11 -> /Applications/Julia-1.1.app/Contents/Resources/julia/bin/julia
lrwxr-xr-x 1 ssiew admin 62 23 Aug 18:42 julia12 -> /Applications/Julia-1.2.app/Contents/Resources/julia/bin/julia
lrwxr-xr-x 1 ssiew admin 62 18 Nov 12:06 julia13 -> /Applications/Julia-1.3.app/Contents/Resources/julia/bin/julia

```

I’m having difficulty with both a new install of v1.3.0 and upgrading from v1.1.0. In both cases the problem seems to be with OpenSpecFun(). In teh latter case I’m getting:

Can you report that issue to [GitHub - JuliaPackaging/BinaryBuilder.jl: Binary Dependency Builder for Julia](https://github.com/JuliaPackaging/BinaryBuilder.jl) ? (Might be a Pkg bug though; not sure).

Can you also please provide `versioninfo()` output?

For the workaround you should be able to pin SpecialFunctions.jl to the previous version, but I can’t check the version number right now
