Hi all,

Last year, we had a discussion on rebase and squash merge PRs to the develop 
branch,

  *   to have linear git history
  *   help with bisecting
  *   easier root cause analysis of failures
  *   easier to backport changes

However, many developers have reached out mentioning that sometimes they have 
clicked the merge button in hurry when they meant to rebase/squash. Once 
clicked there is no going back. All of them suggested that to have the GitHub 
setting on develop branch to rebase and squash merge option and hence there is 
no room for mistakes to occur.

I would like to propose to that we set the GitHub setting on develop PR to 
rebase and squash buttons.

Please do note that this is reversible and can be changed back, hence there is 
no harm in trying it out.


Regards
Nabarun Nag

Subject: Re: [REQUEST] Squash merge please

I’ve noticed quite a few PRs in the last week that were merged with “Merge” 
rather than “Squash and Merge”.

While the community consensus was to continue to allow all merge options, 
please try to default to “Squash and Merge” whenever you can to keep history as 
linear as possible. GitHub will save the last method you used in a cookie, 
which helps, but then it’s easy to miss when it resets itself back to the 
default of “Merge” some months later because you cleared cookies, changed 
browsers, etc.
