Hi, I was about to report that "gbp dch" was not updating the version number in an UNRELEASED entry even after you have merged a new upstream version. But I found this (broader) bug report, covering this and more.
It would be really nice to get the changes documented in this bug report... Cheers, -- ⢀⣴⠾⠻⢶⣦⠀ Raphaël Hertzog <hert...@debian.org> ⣾⠁⢠⠒⠀⣿⡁ ⢿⡄⠘⠷⠚⠋ The Debian Handbook: https://debian-handbook.info/get/ ⠈⠳⣄⠀⠀⠀⠀ Debian Long Term Support: https://deb.li/LTS
