Hi everyone again

After more than two years, we are proud to release FileHelpers 3.2.7!
Thanks to all the contributors and testers!

The packages are available on

We have invested lots of effort in the automatic creation and publishing of NuGet packages.
This should allow us to publish more often and with less effort in the future.

Thank you for your patience and for using FileHelpers,

Marcos Meli & Matthias Cavigelli

Breaking changes & deprecated features
