@jasonsaayman, here it is 👍

I hate to do so, but seeing you did the last release @emilyemorehouse could you give us your advice on this PR? The caching module axio README provides is not working as of axios 0.19. Thanks!

When this can be merged? a lot of plugins have stopped working and waiting for this.

[akirilyuk]

When this will be merged? We would need to implement own solutions otherwise instead using plugins...

@emilyemorehouse @nickuraltsev FWIW, as author of #1395 I'd approve this PR and merge it.

As messy as it is to allow including any properties carried around in the axios config, it was the past behaviour and should definitely be restored. I was not aware of such functionality being relied upon by third-party plugins when making the original PR.

Even if the breaking change stands, is there a strategy for plugins having custom config options to migrate to?

[eaviles]

Looking forward to see this resolved. It would fix: softonic/axios-retry#82

Is this going to be merged?

Hey,

I am a new maintainer for this project. I updated @emilyemorehouse about it. I see one conflict. I am happy to merge unless someone has a clear objection.

There is a conflict right now that needs to be addressed

@rafaelrenanpacheco @felipewmartins as I see, the project does not use the merge strategy.
