Some files present in branch v0.34.x contain multiple references to Tendermint/Tendermint Core:

• CHANGELOG.md (updated in main by main: Use unclog for changelog control #130)
• CODE_OF_CONDUCT.md (updated in main by Update repo root documentation #252)
• CONTRIBUTING.md (updated in main by Update repo root documentation #252)
• README.md (updated in main by Update repo root documentation #252)

• STYLE_GUIDE.md (updated in main by .md - replace references to TM #148)
• UPGRADING.md (updated in main by Update repo root documentation #252)

The following files have no correspondence in the main branch:

• release_notes.md
• PHILOSOPHY.md
• CHANGELOG_PENDING.md

Should we maintain them in v0.34.x branch?
