Here is some guidance to update burpsuite.
Let's assume that we'd like to update to version 2024.3.1.4

	# Get the latest upstream tarball
	uscan -d

	UPSTREAM_VERSION=2024.3.1.4

	# Starting point: the kali/master branch
	git checkout kali/master

	# Create a new upstream branch
	git switch --orphan upstream-"${UPSTREAM_VERSION}"
	tar -xzvf ../burpsuite_"${UPSTREAM_VERSION}".orig.tar.gz
	git add burpsuite.jar
	git commit -m "New upstream version ${UPSTREAM_VERSION}"
	git tag upstream/"${UPSTREAM_VERSION}"

	# Create a new packaging branch
	git checkout -b kali-"${UPSTREAM_VERSION}"
	git restore --source kali/master debian/
	git add debian/
	git commit -m "Copy packaging files" -m "Gbp-Dch: ignore"
	
	# New changelog entry
	gbp dch --commit --release --new-version=${UPSTREAM_VERSION}-0kali1

	# Replace kali/master and force-push
	git branch -D kali/master
	git checkout -b kali/master

	# Push to the repository
	git push -u -f origin kali/master
	git push --all
	git push --tags
