Close issues related to the merge of a pull request.

Useful:

• to close multiple issues related to a pull request.
• to close issues related to a pull request not based on the default branch (ex: master, main). For example, when a branch is related to version (e.g. v1.5, v2.0, ...)

• prefixes (case insensitive): close, closes, closed, fix, fixes, fixed, resolve, resolves, resolved
• issues references separators (can be mixed): (space), , (period)
• prefix and issues references can be separated by: (space), : (colon), or both.

Examples:

Fixes #1,#2,#3
close #1, #2, #3
fix #1 #2 #3
resolve #1,#2 #3
Resolves: #1,#2,#3
closed : #1, #2, #3
