Cannot replace with multiple lines

It seems that bumpversion doesn’t work with multiline string.

Here is my CHANGELOG.md:

## Unreleased ##

  - xxxx

## 0.0.2 -- 2015-12-08 ##

  - yyyy

And here is my .bumpversion.cfg:

[bumpversion:file:CHANGELOG.md]
search = ## Unreleased ##
replace = ## Unreleased ##

  ## {new_version} - {utcnow:%Y-%m-%d} ##

---

After running bumpversion, the expected changelog is:

## Unreleased ##

## 0.0.3 -- 2015-12-09 ##

  - xxxx

## 0.0.2 -- 2015-12-08 ##

  - yyyy

But the actual content is:

## Unreleased ##
## 0.0.3 -- 2015-12-09 ##

  - xxxx

## 0.0.2 -- 2015-12-08 ##

  - yyyy

And .bumpversion.cfg is changed:

[bumpversion:file:CHANGELOG.md]
search = ## Unreleased ##
replace = ## Unreleased ##
        ## {new_version} - {utcnow:%Y-%m-%d} ##

Bumpversion removes the empty line.

How to replace current version with multiline string?

Yes, RawConfigParser in py2 doesn’t recognize empty lines in multiple lines.

Instead of wrapping RawConfigParser, shall we switch to another parser, e.g., a toml parser?

Just in case this is helpful to someone that finds this:

• I figured out it works fine with no spacing if you use rst instead of md.
• You should put this in .bumpversion.cfg instead of setup.cfg if you plan on building in python 3
