Meltano

Could not having the most up to date version of Meltano at all effect ongoing Meltano runs?

Example:
If Meltano were to update on 5/5/2021 and I have a pipeline running daily, but don't update my Meltano project until let's say 5/10/2021... Would my pipeline be effected in anyway?



I am curious just so I know to look out for that and to pay closer attention.

Our aim is certainly that a Meltano project that once worked should always work, no matter how outdated it is. If you run `meltano install` between runs, you could get new (broken?) versions of taps/targets, but you can work around that by pinning your plugin versions (<https://meltano.com/docs/plugin-management.html#pinning-a-plugin-to-a-specific-version>) or just not running `meltano install` when you don't mean to.

Did you see a pipeline break after a new Meltano version was released? If so, we'd treat that as a high priority bug

The only external resource `meltano elt` uses that can change between releases even if your Meltano installation wasn't updated yet is <https://meltano.com/discovery.yml>, which Meltano requests periodically to get the index of discoverable taps/targets, so that we can add new plugins and make them available to users without them needing to update first.

If we change that in a backward incompatible way, that _could_ break an "old" Meltano installation, but we try very hard not to make such changes, and Meltano should be able to gracefully deal with a broken `discovery.yml` and fall back on the copy bundled with the Python package
