How to upgrade Julia to v0.5.0?

Question

now that they release v0.5.0 the question is how can I upgrade from 0.4.6 to 0.5.0 without loosing all my packages? is there even a way. Or if there is no easy way, how have people done it? What is the best way to do it?

Other question is, is it worth it or do I need to upgrade? What are the benefits or why I should not upgrade (yet)? Is there problems with Atom and other packages?

Yes there is quest same question already, but it is for older version and I thought if something has changed on upgrading.

Answer 1

You can go into your .julia/v0.4 folder and copy the REQUIRE file to the v0.5 folder. Then when you Pkg.update() your packages should automatically install.

There are very many upgrades (broadcast syntax, arraypoclypse, string changes, etc.), and many packages may stop supporting v0.4 for this reason. I would recommend you start upgrading soon. Juno has already released its v0.5 version, so when you update it should be compatible.
