NEWS formatting

The recommended strategy for formatting of NEWS.md file is the following:

During development, we can simply add the commit entries as bullet points, such as:

dev

• feat: feature A
• feat: feature B
• fix: Bug A
• fix: Bug B ...

Before making a release, we can then reformat this as follows, to give a better overview:

dev

Features:

• feature A
• feature B

Bugfixes:

• Bug A
• Bug B
