The commit title should reflect the changes, since this is not really an update.

[ftpd]

@Duncaen that's why I've put _3 there (the current revision is _2). If it's not enough, what action should I take to fix it?

[Duncaen]

Its not enough, thats useless information, it tells us nothing, revision increases usually have a reason, be it rebuilds for updated dependencies or patches, but its important to document that reason in the commit message.

[ftpd]

I've put the reason in the first comment of this PR.

Sure, I will change the message if it's still possible now. Can simple --amend do this?

[ftpd]

I've changed the title of the PR, that's the thing I could do for now. Please tell me how to change commit message and I'll gladly do it.

• git --amend the commit message and add more information about this change
• use an email address associated with your github account for the commit, so we can easily see in the github UI who created the commit
• I think you got this patch from somewhere, could you include it whole including the commit message (as you downloaded it from their github/lab without any changes)?
• rename the patch to python3.10.patch
