it was interesting to know that the format has changed again. This on-line tool from @balloob was supposed to help, however, it does not work correctly with the following customization formats:
The new format is actually easier compared to the one inbetween.
Ref is valid YAML, it will just allow you to re-use the same block without specifying it again.
Noticed a bug in the tool, it would not strip the strings properly. Hence the quotation marks around the entities with a space inside. Updated version is here: https://jsfiddle.net/balloob/d2e56q6f/74/
Have been pretty busy of late and have just upgraded from 0.38 to 0.41.
The breaking changes with Customize in 0.39 are causing me a bit of trouble at the moment. I’ve tried using the tool by @balloob to convert but I’m not having much luck.
