Thanks!

[thijstriemstra]

No worries. @sybrenstuvel can you also put out new release/changelog/tag?

[sybrenstuvel]

Sure! Is the changelog up to date (i.e. do I only need to put the date in there)?

[thijstriemstra]

@sybrenstuvel there have been a couple of changes since the last release when looking at the commit log, if you can add those for a 2.3.2 section in changelog I think we're good to go.
