7c6c93d201fix: remove missing comment to follow-up for bitcoin#15864 (Konstantin Akimov)65226da849Merge bitcoin/bitcoin#22229: test: consolidate to f-strings (part 1) (MarcoFalke)ad2c5a53eerefactor: unify feature_notifications.py after #5522 with bitcoin's codebase (Konstantin Akimov) Pull request description: ## Issue being fixed or feature implemented Just one backport bitcoin#22229 because it is a big size, even though there's nothing non-trivial in it. Though, even it is called as part I, there has not been part II yet. ## What was done? Some preparation, code unifications to make bitcoin#22229 with less conflicts and finally backport of itselfl. ## How Has This Been Tested? Run unit & functional test ## Breaking Changes N/A ## Checklist: - [x] I have performed a self-review of my own code - [ ] I have commented my code, particularly in hard-to-understand areas - [ ] I have added or updated relevant unit/integration/functional/e2e tests - [ ] I have made corresponding changes to the documentation - [x] I have assigned this pull request to a milestone ACKs for top commit: UdjinM6: utACK7c6c93d201PastaPastaPasta: utACK7c6c93d201Tree-SHA512: fe296e3255d45a7a1924bd1e5e21634b3cd36ea3f71cf5e8684b54336771665ea7758de7bfc78721669a928f967e7d4db7b1da0a5cd275feb1a2ec0df841ad5c
