New lines in parse

[sharksforarms]

Hello, I'm trying to do a parse/serialize using the following format:

MAJOR=1
MINOR=2
PATCH=3

My bumpversion looks like

[bumpversion]
current_version = 1.2.3

[bumpversion:file:version_info]
parse = "MAJOR=(?P<major>\d+)\nMINOR=(?P<minor>\d+)\nPATCH=(?P<patch>\d+)\n"
serialize = "MAJOR={major}\nMINOR={minor}\nPATCH={patch}\n"

I am getting an assertion error along the lines of:
`AssertionError: Did not find '1.2.3' or 'MAJOR=1\nMINOR=2\nPATCH=3\n' in file version_info
