@nastra could you take a look to see if the proposed update would work based on your release experience?

@jackye1995 should we maybe first get https://github.com/apache/iceberg-docs/pull/187 in? @gaborkaszab was doing the previous release and also added a few good items there

Oh sorry totally overlooked this. @gaborkaszab is it okay if I just include your content there and mark you as coauthor? Otherwise many changes will need to resolve conflict

#187

Hey @jackye1995 , I'd prefer to submit #187 separately. I believe I have addressed all the current comments. Apparently, there is a merge conflict, let me clean that up and ping the participants to see if we can get it merged soon.

@jackye1995 Thanks for creating this PR. I'd love to get this in since we've forgotten to update the Github releases for the last two releases. Would you have time to resolve the conflicts?

Had conflicts with how-to-release

@jackye1995, I'll be updating how to release for the docs section. Once I'm done with that, would you mind moving this over to https://github.com/apache/iceberg/pulls please?
