I see both `v0.7.0` and `v1.0.0` tags are both available. I’m on `v0.6.4`. Should I just go straight to `v1.0.0`?

Are there some “migration” instructions? E.g., I see that `v0.7.0` (and presumably `v1.0.0`) has different package management. I have a `REQUIRE` file for `v0.6.4`; how do I use it to “bootstrap” my `v0.7.0/v1.0.0` system?

What else should I be aware of? Any `Jupyter` or `JupyterLab` issues?

The advice from the core-devs provided earlier regarding this question is as follows: If you port 0.6-\>0.7.0-\>1.0, then the first port 0.6-\>0.7 will give you many deprecation warnings that you can fix all at once. When they are all fixed, the port 0.7-\>1.0 should work without a hitch. On the other hand, 0.6-\>1.0 will break your code (no deprecations, just errors), so it is more tedious to fix the errors. I’m not quite there yet, so I can’t give you advice based on my own experience.

Thanks for your reply.

Is there an easy/fast method to determine package compatibility? For example, I have dozens of packages in my `v0.6.4 REQUIRE` and those packages require other packages. Out of all those packages, which have breaking issues for `v0.7.0/v1.0.0`?

The [juliacon2018 package management presentation](https://youtu.be/GBi__3nF-rM?t=6m25s) was great. It answered a lot of questions and calmed my change-phobia.
