All participants in the Julia community are requested to read the
Julia Community Standards, and abide by them in all Julia related
The primary online discussion venue for Julia is the Discourse forum at
discourse.julialang.org. This is a new site which is
to replace many of the mailing lists below. Announcements will be made on the relevant
lists if and when they are moved.
- julia-news – low traffic mailing list for important announcements, such as new releases.
- julia-opt – discussions related to numerical optimization in julia. This includes Mathematical Programming (linear, mixed-integer, conic, semi-definite, etc.), constrained and unconstrained gradient-based and gradient-free optimization, and related topics.
- JuliaBox – discussions related to running Julia in the so-called cloud.
- julia-users-es – discussions around the usage of Julia in the Spanish language.
The following lists were previously used, and are now in a read-only state for archive purposes:
- julia-users – discussion around the usage of Julia. New users of Julia can ask their questions here. As a courtesy to others, do check the archives and documentation to see if a particular question is already answered.
- julia-dev – discussions related to the development of Julia itself. Note that this is not the primary forum for the development of Julia: most of the discussions take place on GitHub instead (see below).
- julia-stats – special purpose mailing list for discussions related to statistical programming with Julia. Topics of interest include DataFrame support, GLM modeling, and automatic generation of MCMC code for Bayesian models.
We use GitHub to track our source code and for tracking and discussing issues (bugs and their fixes, new features, and proposed changes) and commits. GitHub’s pages are for Julia’s development; for user support, please see julia-users.
There is also a list of packages for Julia, many of which are also hosted on and developed using GitHub.
Various Julia projects are hosted under the following umbrella organizations on GitHub:
