Elixir v1.9.3 released

Release: https://github.com/elixir-lang/elixir/releases/tag/v1.9.3

This release deprecates the use of URLs on mix archive.install, mix escript.install, and mix local.rebar. Support for passing URLs to said commands will be fully removed on Elixir v1.10, as they are unsafe. Thanks to Bram Verburg for the report and for providing a fix.

The alternative is straight-forward: you can simply download the artifact via the command line and then invoke the command with a file system path. For example, instead of:

$ mix archive.install https://example.org/installer.ez

You can execute on Unix (Linux, MacOS X):

$ wget https://example.org/installer.ez
$ mix archive.install installer.ez


$ curl -o installer.ez https://example.org/installer.ez
$ mix archive.install installer.ez

On Windows (Win7 or later):

> powershell -Command "Invoke-WebRequest https://example.org/installer.ez -OutFile installer.ez"
> mix archive.install installer.ez


> powershell -Command "(New-Object Net.WebClient).DownloadFile('https://example.org/installer.ez', 'installer.ez')"
> mix archive.install installer.ez

Note that, if you are a library author, consider providing installable escripts and archives through Hex, such as Phoenix:

$ mix archive.install hex phx_new

Installations through Hex are always safe and they come with version management and all other benefits from Hex too.

Have fun!


There was a tiny regression on v1.9.3 where we were showing deprecation warnings for mix local.hex, which we were not supposed to, so v1.9.4 has been released with a fix.


How do we install 1.9.4?

The installation instructions are on the website: https://elixir-lang.org/install.html

However, depending on how you install it, such as Homebrew for Mac, they may not have updated their repositories with the latest yet. So you have to check and ask the responsible developers, send a PR, or wait if it is not available.

Some options, like the Windows installer, Compiling from source (and perhaps asdf) are always up to date.


Just used brew update and it did install 1.9.4


asdf on Linux 1.9.4 ok too \o/
