How to upgrade Julia to a new release? -


question 1 - upgrade

i'm using v"0.3.8" on windows. found

http://julialang.org/downloads/

current release (v0.3.9)

i know download prebuild version , install again. there way upgrade (from current installed version) new version?

there's pkg.update(), runs long time without output - doesn't work in way.

from documentation:

update() update package metadata repo – kept in pkg.dir("metadata") – update fixed packages can safely pulled origin; call pkg.resolve() determine new optimal set of packages versions.

so not right tool upgrade language itself.

question 2 - release note

is there such thing releasenote or changelist? or hightlight on major change?

(i understand language hasn't reached v1.0. if there place find major change/improvement, that's good. if not, that's fine.)

update: how upgrade julia:

windows & macos & linux

the trivial way of upgrading julia go download page , manually install corresponding binaries. if you're going upgrade julia new major version(e.g. v0.4=>v0.5), can reinstall old packages following steps:

  1. in julia, run pkg.init();
  2. copy require file package directory of old version new 1 (in example .julia/v0.4 .julia/v0.5) overwriting existing file;
  3. in julia, run pkg.resolve() or pkg.update();

macos

if you're using homebrew , homebrew-julia, please follow instructions here.

ubuntu

see @a_a's answer.

to op's question

1.yeah you're right. pkg.update() used updating julia's packages, not julia itself. download prebuild version , install again seems way upgrade julia. or can build julia source https://github.com/julialang/julia.

2.you can find release notes here: https://github.com/julialang/julia/blob/master/news.md
