I added a concept called the feedstock epoch to help us track how feedstocks are reused and to help us easily find all of the artifacts from the previous project(s) built in the feedstock.

What do you think?

[beckermr]

Also thank you for writing this!

[beckermr]

comments @jaimergp ?

[beckermr]

@conda-forge/core comments welcome!

[isuruf]

I really don't like the extra complication with the feedstock epoch. It's just too much to wrap our heads around.

[beckermr]

That's fair. My concern is that overtime we'll loose track of the renames and which versions of the feedstock each artifact came from.

I'm sure all of this can be automated.

Would the automation help assuage your concern or is it deeper than the practical bits of actually making all of the labels etc.?

[h-vetinari]

Thanks for writing this up! I think there's still some things to be fixed/improved.

[beckermr]

OK @isuruf @h-vetinari @jaimergp This is ready for another look!

[h-vetinari]

Thanks a lot, this is getting better and better IMO! A few remaining nits & open points

[isuruf]

What are our thoughts on using epochs in the version? conda metadata spec supports epochs.

I've made a suggestion about this in one of the review threads. Happy to hear other people's thoughts on this.

They are not very user friendly, but if folks want to use them for their packages, then I'd let them go ahead personally. I personally don't think we need core to review their usage.

Hi @conda-forge/core, do you perhaps have any update on this? Thank you in advance :)
