commit 02f1c2d342c3b786489f25495ae746cc268cb604 parent c8ca3c93f6ebf82da0a4bae088e51773f97f8c50 Author: Daniel D’Aquino <daniel@daquino.me> Date: Wed, 20 Nov 2024 11:50:45 -0800 Add script to help identify duplicate changelog entries This commit adds a new script to devtools that can be used to help identify duplicate changelog entries. It works by identifying duplicate lines in CHANGELOG.md, and then searching whether each one of those duplicate lines are present in a separate text file (which can be a subset of the changelog that the user is interested in analyzing) No user-facing changes Changelog-None Signed-off-by: Daniel D’Aquino <daniel@daquino.me> Diffstat:
