Since version 2.23, git-blame has a feature to ignore certain commits. This feature is useful to ignore large formatting or apparently unimportant changes.

How to use

1. Create a revisions list file. The file name is usually .git-blame-ignore-revs
2. Set the file as a default ignore file for blame by git config blame.ignoreRevsFile .git-blame-ignore-revs

The file format is described in git-fsck's man: https://git-scm.com/docs/git-fsck#Documentation/git-fsck.txt-fsckskipList
