bumpversion fails when version is wrapped in quotes

See original GitHub issue

I have several applications that use bumpversion. The latest release has caused a breaking change. I have files like the following


current_version = 1.90.0
parse = (?P<major>\d+)\.(?P<minor>\d+)\.(?P<patch>\d+)
commit = True
tag = True
message = "Bump version: {current_version} → {new_version} [ci skip]"
serialize = 

search = CONF_VERSION={current_version}
replace = {new_version}


when my build runs bumpversion minor it errors because it cannot find the version in the file I figured out the it is because the value in wrapped in single quotes. This worked fine in version 1.0.0 but is now broken in 1.0.1

There was some breaking change. But it is still usable, just change your .bumpversion.cfg to:

search = CONF_VERSION='{current_version}'
replace = CONF_VERSION='{new_version}'

In my opinion the previous behavior sounds strange… maybe it did not find the search-string and then did fall back to the default search/replace?

I just confirmed, bumpversion is no longer usable due to this error. I recommend that users use
